A brief guide to Navigating EGU 2019!

A brief guide to Navigating EGU 2019!

Are you going to the EGU General Assembly in Vienna next week? If so, read on for a quick guide to navigating the week: Where to start, what to see and how to meet people and enjoy yourself! After all, the meeting is as much about the opportunities to meet scientists from all over the world as it is about the science itself.


How on Earth do I know what is going on?!

The EGU General Assembly (GA) is a massive meeting with many parallel session, short courses, medal lectures and much more. So how do you know what is going on and when, and how can you effectively keep track of it all?

The simplest way is to use the online EGU program – it has options to browse sessions of interest chronologically or by discipline. You can simply click on a session or an individual presentation to add it to your personal programme. You can then view your personal program online, print it as a PDF or use the EGU2019 mobile app to keep track of your personal program on the go. The app also has a handy map feature, to help you find your way around AND new for 2019, a digital version of “EGU Today” – the daily EGU GA newsletter

Don’t forget to keep track of the twitter hastags #EGU19 and #EGU19_CR to see what is happening on a second by second basis and also the @EGU_CR twitter feed!

New Schedule for 2019!

The eagle-eyed amongst you may have spotted that the timing of sessions at EGU has changed this year. The new schedule has posters, orals and PICOs in parallel (posters always used to be in the afternoon only!)  and each “block” (i.e. one session of talks, posters or PICOs) is 15 minutes longer than before.

  • 08:30–10:15 – Posters, orals, PICOs
  • 10:15–10:45 – Coffee break
  • 10:45–12:30 – Posters, orals, PICOs
  • 12:30–14:00 – Lunch break
  • 14:00–15:45 – Posters, orals, PICOs
  • 15:45–16:15 – Coffee break
  • 16:15–18:00  – Posters, orals, PICOs
  • 18:00–19:00  – Beer/soft drinks – Networking
  • 19:00–20:00 – Townhall meetings, (some) medal lectures, (some) short courses, special events!

Note: If you have a poster, you should put it up before 08:30 on the day of your session. It will stay up all day, but you will only be expected to stand by it and present in your allocation time slot. Don’t forget to take it down between 19:00-19:30 if you want to keep it!


Urm… so I made it to Vienna – where is the conference centre?

The EGU General Assembly is held at the Austria Center Vienna (ACV) each year. The nearest metro stop is “Kaisermühlen/Vienna Int. Centre” on the U1 line – here is a handy Metro Plan! When you leave the station there will be plenty of signs to the conference – if in doubt follow the large group of Geoscientists (they can usually be recognised by their practical footwear and waterproof jackets 😉 )

The registration fee to the General Assembly includes a public transportation ticket. The public transportation ticket is valid Monday–Friday, 8–12 April 2019. More info on travel can be found here.


Social events Cryospheric Scientists!

So you have spend your days at EGU absorbing plenty of science… but there is another very important aspect to conferences – they are a great place to socialise! However, it can be very daunting to know how and where to meet people at such a large meeting.

This year the EGU Cryosphere team are organising two social events joint with APECS. Come along, meet some new people and enjoy a coffee, beer, soft drink – whatever takes your fancy! We also wanted to highlight this year’s Pride@EGU event – open to anyone!

Pre-Icebreaker Meet Up

When and Where: Sunday 7 Apr, from 16:00-18:00 at Cafe Merkur (U-bahn –  U2 – Rathaus)

Pre-icebreaker meet up EGU 2017

The conference icebreaker can be a daunting experience to attend alone but it is a great event to go along to. We are organising a friendly pre-icebreaker meet up for cryospheric and polar ECSs. We will meet up, have a chat, have a coffee/beer/cake and then head to the EGU conference centre together in time for the main icebreaker. Keep your eyes on the Facebook event for more details!

Cryo Drinks!

When and Where: Tuesday evening 9th April from 20:30 at Brandauer Bierbögen (U-bahn – Spittelau – U4 & U6)

This year we are there will be a return of the infamous Cryo meet-up with a small change – it will be a drinks only event this year (it was simply too big and hectic with everyone eating last year!). So come along and meet some fellow cryo-people old and new. If you want to travel from the conference centre together, we will meet after the ECS Networking Event at 20:00 at the main entrance (look for the blue and white EGU Cryosphere signs!) or you can meet us at Brandauer Bierbögen from 20:30.

Please remember to bring cash to pay for your own drinks (it will be very slow if 50+ people are trying to pay by card!)

Follow the Facebook event for updates and hopefully see plenty of faces old and new there 😀

Pride @ EGU

When and Where: Tuesday 9th April, 15:00-16:00 – Networking & ECS Zone (Red Level)

The main event is from 15:00 – 16:00 plus Twitter chat from 14:30! Pop along to support and find out more about the LGBTQA+ community at EGU. Open to anyone who is interested.


Conference highlights for ECSs:

There are so many courses and sessions running at EGU this year – we have highlighted a few below, but be sure to check out the full list in the online program (see above) as well as this helpful guide to “Session of special interest to Early Career Scientists (ECS)” published by EGU and this blog post “What is on for ECSs at EGU” by Oliver Trani the EGU Communications officer.

How to navigate EGU: tips & tricks

When and Where: Monday 08th Apr, 08:30–10:15 / Room -2.16 (Brown Level)

Held first thing on Monday morning, this could be just the session you need to get your week off to a productive start!

Help! I’m presenting at a scientific conference!

When and Where: Monday 08th Apr, 14:00–15:45 / Room -2.62 (Brown Level)

Presenting at a scientific conference can be daunting for early career scientist and established. How can you optimally take advantage of those 12 minutes to communicate your research effectively? How do you cope with nervousness? What happens if someone asks a question that you don’t think you can answer?

Come along to this short course on the Monday of EGU for some tips, tricks and advice!

Polar Science Career Panel (EGU Cryosphere and APECS)

When and Where: Tuesday 9th Apr, 12:45–13:45 / Room -2.32 (Brown Level)

Many early career scientists come to EGU looking for inspiration to take the next step in their careers. There are so many opportunities both academic and elsewhere that it can be daunting to know where to start looking and what the options are. Join us for a panel discussion about everything to do with life post-polar-PhD and expand your ideas about where you might go next!

If you can’t make it on the day, but want to see what our panelists have to say, follow the @EGU_CR twitter feed and hastag #EGU19_CR for a live-tweet of the event!

Cryosphere Division Meeting

When and Where: Thursday 11th Apr, 12:45–13:45 / Room N1 (Green Level)

Each division at EGU has a meeting during the GA, please come along to the Cryosphere Divisions meeting to learn more about what the EGU CR division does, who runs it and have your say! ECSs are particularly important – you are the future of EGU!

Meet The Cryosphere Editor! 

When and Where: Friday 12th Apr, 16:15–18:00 / Room -2.31 (Brown Level)

Publishing your research in a peer reviewed journal is essential for a career in research, however, getting those first few papers submitted can be daunting. This short course, given by the co editor-in-chief of The Cryosphere Thomas Mölg, will cover all you need to know about the publication process from start to end!


Things to keep in Mind:

This comes from a longer list the EGU provide here, but these are my highlights!

  • Bring a water bottle! There are water fountains all around the building and Vienna tap water is delicious!
  • EGU’s person of trust: if you experienced infringements against the rules of conduct, feel uncomfortable or experience any harassment, upset or abuse during the meeting, please contact EGU’s person of trust at the special registration desk in Hall X5. You can also contact the EGU Information in the entrance hall (Yellow Level 0 – ground floor) and they will call the person of trust. It is also possible to report to conduct@egu.eu.
  • Preferred pronouns: pick up a badge for your lanyard with your preferred pronouns from the EGU Booth in Hall X2 (Brown Level -2 – basement), the registration help desk in Hall X5, or the EGU Information (Yellow Level 0 – ground floor).

Some more general advice from your Cryosphere ECS rep…

The General Assembly can be an overwhelming experience. Take advantage of the lunch breaks and go for a walk! When you exit the main conference building turn left and head for the river, or turn right and you will find that behind the concrete buildings there is a very nice park. Beyond that, explore Vienna and treat yourself to a bit of time off to recover during the week. It is more important to pay attention to the sessions you do attend than attend ALL of the possible sessions. Did you know a Vienna U-Bahn ticket is included in the registration fee? Jump on a train the centre of town and go for a stroll!


Am I an ECS?

The EGU officially defines an Early Career Scientist (ECS) as:

an undergraduate or postgraduate (Masters/PhD) student or a scientist who has received his or her highest degree (BSc, MSc, or PhD) within the past seven years  (where appropriate, up to one year of parental leave time may be added per child).

However, everyone is of course more than welcome to come along and attend the short courses and social events organised by your ECS team, the more the merrier!

Image of the Week – Inspiring Girls!

Image of the Week – Inspiring Girls!

What, you may ask, are this group of 22 women doing standing around a fire-pit and what does this have to do with the EGU Cryosphere blog? This group of scientists, artists, teachers, and coaches gathered 2 weeks ago in Switzerland to learn how to become instructors on an Inspiring Girls Expedition. But what, you may ask again, is an Inspiring Girls Expedition? Well read on to find out more…


What is an Inspiring Girls Expedition?

In 1999 Glaciologist Erin Petit, Geographer Michele Koppes, and 5 high-school girls hiked out onto the South Cascade Glacier in Washington State. For the next week, this motley crew spent their time camped out on a glacier moraine, exploring the landscape and performing scientific experiments by day, and talking and listening to each others thoughts and stories by night – that was the birth of Girls on Ice.

Over the next 13 years, more expeditions took place and more instructors (scientists, artists and mountain guides) started to get involved. In 2012, a second Girls on Ice expedition was born in Alaska and, in the years since, there have been Girls on Ice expeditions in 4 different locations and in 2 different languages! The idea has expanded to other areas of wilderness expedition as well, with new projects starting up: Girls on Rock, Girls in Icy Fjords and Girls on Water – nowadays these expedition are collectively known as Inspiring Girls Expeditions!

But I haven’t really answered the question – what is an Inspiring Girls Expedition? It is a wilderness and science education program for high-school aged girls. Over the course of around 12 days, these girls get the chance to explore a wilderness setting, learn about scientific thinking, increase self-confidence, and push their physical and intellectual boundaries as part of a single-gendered team. And, importantly – it’s FREE – opening it up to girls who might not have the financial means to do something like this otherwise. Everyone who goes on the expedition from scientists to mountain guides and instructors is female, making this expedition pretty unique! I think the philosophy of Inspiring Girls is best described by their mission statement:

Our mission is to bring out your natural curiosity, inspire your interest in science, connect the arts and sciences, free you from gender roles, provide a less competitive atmosphere, and encourage trust in your physical abilities.

The workshop

I’ve been following the work of Girls on Ice for a while, so when I saw a chance to go on an instructor training course, I enthusiastically signed up! Over 4 days in June 2018, a group of women from at least 8 different countries got together in a hiking hut in Switzerland for an Inspiring Girls Instructor Workshop, hosted by Swiss Girls on Ice. We came from a broad range of backgrounds: glaciologists, climate scientists, biologists, artists, architects, professional coaches, teachers (I hope I haven’t forgotten anyone!). We started off by learning more about the Inspiring Girls philosophy, what they expeditions aim to teach, and how they keep the girls safe and deal with any issues that might arise. Then came the thinking part for us…How do you teach in a wilderness setting? How to keep teenage girls engaged in what you are doing? What is a good leader? This gave us a lot of food for thought and we discussed a lot of these issues late into the evenings!

Then the fun part (although we all look rather serious in the pictures – below), working on ideas for new Inspiring Girls Expeditions (the current expeditions are often over-subscribed so there is certainly scope for more expeditions in more places) with the hope of inspiring more girls! So definitely watch this space for more expeditions coming to a mountain, cave or forest near you!

It was a fantastic few days, with a fantastic bunch of women and I certainly came away feeling inspired myself!

I have to admit, this isn’t your usual Image of the Week blog post, however, I hope the relevance to scientists, science educators, and anyone else that follows the blog is clear! There is a need to show girls and young women that they have the potential to do what they want: be that a glaciologist, a mountain guide (both very much male dominated careers) or something entirely different! This type of expedition, in a single-gendered environment, is a very effective way to help build courage, confidence, and self-reliance!

This sounds cool – how can I get involved?

The team at Inspiring Girls are always looking for new people who are keen and enthusiastic about their project to get involved as volunteers, by donating a bit of cash or simply spreading the word about the expeditions – check their website to see how you can help out!

What’s on at POLAR18?

What’s on at POLAR18?

Next Tuesday (19th June) the POLAR18 Open Science Conference kicks off in Davos, Switzerland. We have put together a quick guide about events that might be of interest to you during the week! Conferences are about the science, of course, but the social side is just as important 🙂


What is POLAR18?

The eagle-eyed among you will have spotted that the POLAR18 conference is, in fact, a collection of different meetings held between the 15th-26th June, it’s quite confusing at first glance, so here is a summary of what is going on!

  • 15 – 18 June – SCAR and IASC/ASSW Business & Satellite Meetings (i.e. Side meetings and workshops) – details here.
  • 19 – 23 June  – SCAR/IASC Open Science Conference & Open COMNAP Session (i.e. the main event!)
    • Main program here – this will be the most important part for most of you!
    • Side meetings program here
  • 24 – 26 June – SCAR Delegates Meeting & 2018 Arctic Observing Summit – details here.

Venue

The conference and side meetings are held at the Congress Centre Davos which is in the middle of town (see map below). It is easy to walk around Davos, but if you want to use the local buses you get a free “Guest Card” bus ticket included with most hotel, hostel and apartment bookings.

Needless to say, Davos is a great place to be if you like biking, hiking, trail running and just generally being outside – for ideas on what to do, check out the Q&A section of the POLAR18 website.


Events for ECSs

There is a lot going on during the week – below we have listed just some of the social and networking events we think might be of particular interest to ECSs.

APECS World Summit – Sunday 17th and Monday 18th June

The Association for Polar Early Career Scientists (APECS) is excited to invite members and other early career professionals from around the globe to our 2nd APECS World Summit 2018! Hosted directly before POLAR2018 – the theme for this two-day event on 17-18 June will be “Connecting the Poles”. Please check out this link for more information and very important – YOU NEED TO REGISTER!

Southern Ocean Data Hack 2018 – Sunday 17th June, from 8:00 AM – 4:00 PM

A brief guide to Navigating EGU 2018!

A brief guide to Navigating EGU 2018!

Are you going to the EGU General Assembly in Vienna in just over a week? If so, read on for a quick guide to navigating the week: Where to start, what to see and how to meet people and enjoy yourself! After all, the meeting is as much about the opportunities to meet scientists from all over the world as it is about the science itself.


How on Earth do I know what is going on?!

The EGU General Assembly is a massive meeting with many parallel session, short courses, medal lectures and much more. So how do you know what is going on and when, and how can you effectively keep track of it all?

The simplest way is to use the online EGU program – it has options to browse sessions of interest chronologically or by discipline. You can simply click on a session or an individual presentation to add it to your personal programme. You can then view your personal program online, print it as a PDF or use the EGU2018 mobile app to keep track of your personal program on the go – scan the QR code to download it or click here from your smartphone. The app also has a handy map feature, which can be a great help navigating such a large venue!

Don’t forget to keep track of the twitter hastag #EGU18 to see what is happening on a second by second basis and also the @EGU_CR twitter feed and hashtag  for cryo-info!


Urm… so I’m in Vienna – where is the conference centre?

The EGU General Assembly is held at the Austria Center Vienna (ACV) each year. The nearest metro stop is “Kaisermühlen/Vienna Int. Centre” on the U1 line – here is a handy Metro Plan! When you leave the station there will be plenty of signs to the conference – if in doubt follow the large group of Geoscientists (they can usually be recognised by their practical footwear and waterproof jackets 😉 )

The registration fee to the General Assembly includes a public transportation ticket. The public transportation ticket is valid Monday–Friday, 9–13 April 2018. More info on travel can be found here.


Social events for Early Career Cryosphere Scientists!

So you have spend your days at EGU absorbing plenty of science… but there is another very important aspect to conferences – they are a great place to socialise! However, it can be very daunting to know how and where to meet people at such a large meeting.

This year the EGU Cryosphere team are organising two social events joint with APECS, as well as a lunch for anyone who is interested in joining our blog/social media team. Come along, meet some new people and enjoy some tasty food and a cold beer or two!

Pre-Icebreaker Meet Up

When and Where: Sunday 8 Apr, from 16:00-18:00 at Cafe Merkur

The conference icebreaker can be a daunting experience to attend alone but it is a great event to go along to. We are organising a friendly pre-icebreaker meet up for cryospheric ECSs. We will meet up, have a chat, eat some cake and then head to the EGU conference centre together in time for the main icebreaker. Keep your eyes on the Facebook event for more details!

Cryo Night Out!

When and Where: Wednesday evening 11 April from 19:30 in Zwölf-Apostelkeller

There will be a return of the infamous joint APECS and EGU Cryosphere division night out come and join us for Viennese food and drinks and plenty of laughs! If you want to travel from the conference centre together, we will meet after the poster session at 18:50 at the main entrance (look for the blue and white EGU Cryosphere signs!) or you can meet us at Zwölf-Apostelkeller at 19:30. Two important things to do if you would like to come:

  • Please fill out Doodle poll to give us an idea of numbers!
  • Please remember to bring cash to pay for your own meal and drinks (it is possible to pay by card, but it will be very slow if 50+ people are trying to do it!)

Follow the Facebook event for updates and hopefully see plenty of faces old and new there 😀

EGU Cryosphere Blog and Social Media Team Lunch

When and Where: Wednesday lunchtime (12:15), on the left when looking at the main entrance.

Come along for an informal lunch meeting if you are already — or interested in getting — involved in the EGU Cryosphere team (which includes this blog and out social media channels). We will meet on the left of the main entrance to the conference centre at 12:15 and then we will decide on where to go depending on the weather. Don’t forget to bring your lunch with you. Please email Sophie Berger for more details.


Short courses

As well as the scientific sessions, did you know there are also other sessions called “short courses” at EGU? Short courses provide a great chance to learn about a topic, skill or piece of software that has been on your to do list, so why not drop by and meet the experts who have kindly agreed to participate and share their knowledge?

There are many courses running at EGU this year – we have highlighted a few below, but be sure to check out the full list in the online program (see above) as well as this helpful guide to “Session of special interest to Early Career Scientists (ECS)” published by EGU.

How to navigate EGU: tips & tricks

When and Where: Monday 09 Apr, 08:30–10:00 / Room -2.91

Held first thing on Monday morning, this could be just the session you need to get your week off to a productive start!

Help! I’m presenting at a scientific conference!

When and Where: Monday 09 Apr, 13:30–15:00 / Room -2.16

Presenting at a scientific conference can be daunting for early career scientist and established. How can you optimally take advantage of those 12 minutes to communicate your research effectively? How do you cope with nervousness? What happens if someone asks a question that you don’t think you can answer?

Come along to this short course on the Monday of EGU for some tips, tricks and advice!

Polar Science Career Panel (EGU Cryosphere and APECS)

When and Where: Tuesday 10 Apr, 12:15–13:15 / Room -2.85

Many early career scientists come to EGU looking for inspiration to take the next step in their careers. There are so many opportunities both academic and elsewhere that it can be daunting to know where to start looking and what the options are. Join us for a panel discussion about everything to do with life post-polar-PhD and expand your ideas about where you might go next. Our panelists are:

  • Rob Bingham – Reader in Glaciology and Geophysics at Uni. Edinburgh, UK
  • Maria Eden, project manager of Beyond EPICA: Oldest Ice
  • Daisy Dunne, journalist for Carbon Brief
  • Nora Helbig, research Scientist at SLF in Davos
  • Helge Goessling, Junior Research Group leader at AWI, Bremerhaven

If you can’t make it on the day, but want to see what our panelists have to say, follow the  hashtag for a live-tweet of the event!

Communicating geoscience to the media 

When and Where: Tuesday 10 Apr, 15:30–17:00 / Room -2.31

The news media is a powerful tool to help scientists communicate their research to wider audiences. However, at times, messages in news reports do not properly reflect the real scientific facts and discoveries, resulting in misleading coverage and wary scientists.  In this short course, co-organised with the CL and CR divisions, we will bring together science journalists and researchers with experience working with the media to provide tips and tricks on how scientists can better prepare for interviews with reporters.

Heads up: over EGU Cryosphere’s very own Sophie Berger will be one of the speakers! 😀


Am I an ECS?

The EGU officially defines an Early Career Scientist (ECS) as:

an undergraduate or postgraduate (Masters/PhD) student or a scientist who has received his or her highest degree (BSc, MSc, or PhD) within the past seven years  (where appropriate, up to one year of parental leave time may be added per child).

However, everyone is of course more than welcome to come along and attend the short courses and social events organised by your ECS team, the more the merrier!


General Advice….

The General Assembly can be an overwhelming experience. Here are some tips which have been passed down over the years from one ECS Rep to another:

  • Take advantage of the lunch breaks and go for a walk! When you exit the main conference building turn left and head for the river, or turn right and you will find that behind the concrete buildings there is a very nice park.
  • Don’t get star-struck by a “big name” scientist you have always wanted to talk to – remember they are just humans (and usually friendly)! Go and introduce yourself and tell them what you do – the afternoon poster session is often a good chance to do this!
  • Go to a session outside your field or area of interest. Even in completely different research topics, similarities in methods or applications can inspire you to think differently about your own research.
  • Explore Vienna and treat yourself to a bit of time off to recover during the week. It is more important to pay attention to the sessions you do attend than attend ALL of the possible sessions. Did you know a Vienna U-Bahn ticket is included in the registration fee? Jump on a train the centre of town and go for a stroll!

Image of the Week – Vibrating Ice Shelf!

Image of the Week – Vibrating Ice Shelf!

If you listen carefully to the Ekström ice shelf in Antarctica, a strange sound can be heard! The sound of a vibrating truck sending sounds waves into the ice. These sound waves are used to “look” through the ice and create a seismic profile of what lies beneath the ice surface. Read on to find out how the technique works and for a special Cryosphere Christmas message!


What are we doing with this vibrating truck on an ice shelf?

In early December a team from the Alfred Wegener Institute (AWI) made a science traverse of the Ekström ice shelf, near the German Neumayer III Station. Their aim was to make a seismic survey of the area. The seismic source (sound source) used to make this survey was a vibrating truck, known as a Vibroseis source (Fig. 2).

Fig. 2: The Vibroseis truck. It is attached to a “poly-sled” so that it can be easily towed across the ice shelf. The vibrating plate can be seen suspended below the centre of the truck. [Credit: Judith Neunhaeuserer]

It has a round metal plate, which is lowered onto the ice-shelf surface and vibrates at a range of frequencies, sending sound waves into the ice. When the snow is soft the plate often sinks a little, leaving a rather strange “footprint” in the snow (Fig. 3).

Fig. 3: The “footprint” of the Vibroseis truck plate in the snow [Credit: Olaf Eisen].

The sound waves generated travel through the ice shelf, through the water underneath and into the rock and sediment of the sea floor, they are reflected back off these different layer and these reflections are recorded back on the ice surface by a string of recording instruments – geophones (Fig 1). There are sixty geophones in a long string, a snow streamer, which can be towed behind the truck as it moves from location to location. By analyzing how long it takes the sound waves to travel from the source to the geophones an “image” of the structures beneath the ice can be made. For example, you can see a reflection from the bottom of the ice shelf and from the sea floor as well as different layers of rock and sediment beneath the sea floor. This allows the team to look into the geological and glaciological history of the area, as well as understand current glaciology and oceanographic processes!

 

As it happens, the team from AWI consists of your very own EGU Cryosphere Division President, Olaf Eisen and ECS Rep, Emma Smith! As this is the last post before Christmas, we wanted to wish you a merry Christmas from Antarctica!

Merry Christmas! As you can see the weather is beautiful here! [Credit: Jan-Marcus Nasse]

Image of the Week – See sea ice from 1901!

Image of the Week – See sea ice from 1901!

The EGU Cryosphere blog has reported on several studies of Antarctic sea ice (for example, here and here) made from high-tech satellites, but these records only extend back to the 1970s, when the satellite records began. Is it possible to work out what sea ice conditions were like before this time? The short answer is YES…or this would be a very boring blog post! Read on to find out how heroic explorers of the past are helping to inform the future.


During the Heroic Age of Antarctic Exploration (1897–1917), expeditions to the “South” by explorers such as Scott and Shackleton involved a great deal of time aboard ship. Our image of the week shows one such ship – the ship of the German Erich von Drygalsk – captured from a hot air balloon in 1901.

These ships spent many months navigating paths through sea ice and keeping detailed logs of their observations along the way. Climate scientists at the University of Reading, UK have used these logs to reconstruct sea-ice extent in Antarctica at this time – providing key information to extend satellite observations of sea ice around the continent.

Why do we want to know about sea-ice extent 100 years ago?

In the last three decades, satellite records of Antarctic sea-ice extent have shown an increase, in contrast to a rapid decrease in Arctic sea-ice extent over the same period (see our previous post). It is not clear if this, somewhat confusing, trend is unusual or has been seen before and without a longer record, it is not possible to say. This limits how well the sensitivity of sea ice to climate change can be understood and how well climate models that predict future ice extent can be validated.

To help understand this increase in Antarctic sea-ice extent; records of ice composition and nature from ships log books recorded between 1897–1917 have been collated and compared to present-day ice conditions (1989–2014).

What does the study show?

The comparison between sea ice extent in the Heroic Age and today shows that the area of sea ice around Antarctica has only changed in size by a very small amount in the last ~100 years. Except in the Weddell sea, where ice extent was 1.71o (~80 km) further North in the Heroic Age, conditions comparable to present-day were seen around most of Antarctica. This suggests that Antarctic sea-ice extent is much less sensitive to the effects of climate change than that Arctic sea ice. One of the authors of the study, Jonny Day, summarises these findings in the video below:

Image of the Week – A rather splendid round-up of CryoEGU!

Image of the Week – A rather splendid round-up of CryoEGU!

The 2017 edition of the EGU general assembly was a great success overall and for the cryospheric division in particular. We were for instance thrilled to see that two of the three winning photos of the EGU Photo contest featured ice! To mark the occasion we are delighted to use as our image of this week,  one of these pictures, which  shows an impressive rapid in the Pite River in northern Sweden. Congratulations to Michael Grund for capturing this stunning shot.  You can find all photos entered in the contest on imaggeo — the EGU’s  open access geosciences image repository.

But being the most photogenic division (at least the ice itself is…not sure about the division team itself!) was not our only cryo-achievement during the conference. Read on to get the most of (cryo)EGU 2017!


EGU 2017 in figures

  • 17,399 abstracts in the programme (including 1179 to cryo-related sessions)
  • 14,496 scientists from 107 countries attending the conference
  • 11,312 poster, 4,849 oral and 1,238 PICO presentations
  • 649 scientific sessions and 88 short courses
  • 53% of early-career scientists

Polar Science Career Panel

During the week we teamed up with APECS to put on a Polar Science Career Panel. Our five panellists, from different backgrounds and job fields, engaged in a lively discussion with over 50 session attendees. With many key topics being frankly and honesty discussed by our panelists, who had some great comments and advice to offer. Highlights of the discussion can be found on the @EGU_CR twitter feed with #CareerPanel.

At the end we asked each panellist to come up with some final words of advice for early-career scientists, which were:

  • There is no right and wrong, ask other people and see what you like
  • Remember you can shape your own job
  • Take chances! Even if you are likely to fail and think outside the box
  • Remember that you are a whole human being… not only a scientist and use all your skills
  • And last but not least… come and work at Carbon Brief (thanks Robert McSweeney!!)

However, the most memorable quotation of the entire panel is arguably from Kerim Nisancioglu :

Social media

One of the things the EGU Cryosphere team has been recognised for is its great social media presence. We tweeted away pre-EGU with plenty of advice, tips and information about events during the week and also made sure to keep our followers up-to-date during the week.
If it is not yet the case, please consider following us on twitter and/or facebook to keep updated with the latest news about the cryosphere division, the EGU or any other interesting cryo-related news!

We need YOU for the EGU cryosphere division

Conferences are usually a great way to meet new people but did you know that getting involved with the outreach activities of the division is another way?

Each division has an ECS (early-career scientist) representative and a team to go with that and the Cryosphere division is one of the most active. Our new team of early-career scientists for 2017/18 includes some well known faces and some who are new to the division this year:

Nanna Karlsson : outgoing ECS representative and incoming coordinator for posters and PICOs awards

Emma Smith : incoming ECS representative and outgoing co-chief editor of the  cryoblog

Sophie Berger: chief-editor of the cryoblog and incoming outreach officer

Clara Burgard : incoming co-chief editor the cryoblog

 

 

 

We also have many more people (who aren’t named above) involved in the blog and social media team AND the good news is that we are looking for new people to either run our social media accounts and/or contribute regularly to this “award winning” cryoblog. Please get in touch with Emma Smith (ECS Representative and former blog editor) or Sophie Berger (Chief Blog Editor and Outreach Officer) if you would like to get involved in any aspect of the EGU Cryosphere team. No experience is necessary just enthusiasm and a love of bad puns!

And here is your “Save the Date” for EGU 2018 – which will be held between 8th – 13th April 2018.

A brief guide to navigating EGU 2017!

A brief guide to navigating EGU 2017!

Are you going to the EGU General Assembly in Vienna next week? If so, read on for a quick guide to navigating the week: Where to start, what to see and how to meet people and enjoy yourself! After all, the meeting is as much about the opportunities meet scientists from all over the world as it is about the science itself.


How on Earth do I know what is going on?!

The EGU General Assembly is a massive meeting with many parallel session, short courses, medal lectures and much more. So how do you know what is going on and when, and how can you effectively keep track of it all? The simplest way is to use the online EGU program – it has options to browse sessions of interest chronologically or by discipline. You can simply click on a session or an individual presentation to add it to your personal programme. You can then view your personal program online, print it as a PDF or if you have a smartphone you can also use the EGU2017 mobile app to keep track of your personal program on the go – scan the QR code to download it or click here from your smartphone.

Don’t forget to keep track of the twitter hastag #EGU17 to see what is happening on a second by second basis and also the #CryoEGU17 hashtag for up-to-date cryosphere news.


Short courses

Short courses at EGU are designed to give you an insight into a certain area or topic and cover all sorts of subjects and skills. There are many courses running at EGU this year – we have highlighted a few below, but be sure to check out the full list in the online program. Short courses provide a great chance to learn about a topic, skill or piece of software that has been on your to do list, so why not drop by and meet the experts who have kindly agreed to participate and share their knowledge?

How to navigate EGU: tips & tricks

When and Where: Mon, 24 Apr, 08:30–10:00,  Room -2.31

Social event for Early Career Cryosphere Scientists!

So you have an idea of what scientific stuff is going on, but there is, of course, another important aspect to any conference…. they are a great place to socialise! However, it can be very daunting to know how and where to meet people at such a large meeting. This year the EGU Cryosphere team are organising two social events joint with APECS as well as a lunch for anyone who is interested in joining our blog team – also don’t forget the March for Science taking place on Saturday the 22nd April.

Pre-Icebreaker Meet Up

The conference icebreaker can be a daunting experience to attend alone but it is a great event to go along to. We are organising a friendly pre-icebreaker meet up for cryospheric ECSs on Sunday 23rd from 16:00We will meet at a yet-to-be-determined cafe in Vienna, have a chat, do some networking, have a cake and then head to the EGU conference centre together in time for the icebreaker. Keep your eyes on the Facebook event for more details!

Cryo Night Out!

On Thursday evening (27th), after the Polar Science Career Panel there will be a joint APECS and EGU Cryosphere division night out. We will be leaving from the conference centre after the panel session (Room -2.16) and heading for Wieden Braü for food and drinks, you can walk down with us as a group or meet there at 19:30. If you would like to eat please fill out the Facebook poll to give us an idea of numbers! Hopefully see plenty of faces old and new there 😀

EGU Cryosphere Bloggers Lunch

An informal lunch meeting for anyone interested in getting involved in the EGU Cryosphere blog on Tuesday 25th. Meet in front of the main entrance at 12:15 and we will decide on where to go depending on the weather. Please email the editors Emma (emma.smith@awi.de) or Sophie (sberger@ulb.ac.be) if you want to come along but aren’t sure who to look for. As an extra incentive Sophie will be bringing some Belgian chocolate!!

Ice Core Young Scientist (ICYS) social

Early-career scientists with an interest in ice cores are invited to join the Ice Core Young Scientists (ICYS) for a get-together with drinks and/or dinner on Tuesday 25th, from 18:30 (more details on facebook).
The get-together will take place at Café Einstein, Rathausplatz 4, Vienna . For those going directly from the conference venue, we will be leaving from there at 17:45, and you can find us (Mai Winstrup & Emma Kahle) by the main entrance.

March for Science

The day before the official start of the EGU GA (Saturday 22nd April) is Earth Day. On this day scientists and science enthusiasts across the globe will be marching to celebrate science and to call for the safeguarding of its future. A satellite march organised by local researchers is taking place in Vienna. If you are going to be in Vienna on the Saturday then it is a great chance to get involved – find out more details, including where and when to meet, on the EGU blog.


Am I an ECS?

The EGU officially defines an Early Career Scientist (ECS) as:

an undergraduate or postgraduate (Masters/PhD) student or a scientist who has received his or her highest degree (BSc, MSc, or PhD) within the past seven years  (where appropriate, up to one year of parental leave time may be added per child).

However, everyone is of course more than welcome to come along and  attend the short courses and social events organised by your ECS team, the more the merrier!


General Advice….

The General Assembly can be an overwhelming experience. Here are some tips from the EGU Cryosphere’s esteemed ECS representative Nanna Karlsson:

  • Take advantage of the lunch breaks and go for a walk! When you exit the main conference building turn left and head for the river, or turn right and you will find that behind the concrete buildings there is a very nice park.
  • Go to a session outside your field or area of interest. Even in completely different research topics, I often find similarities in methods or applications that inspire me to think differently about my own research.
  • Explore Vienna and treat yourself to a bit of time off to recover during the week. If your programme is completely packed, then hurry to the U-Bahn in a lunch break (the ticket is after all included in the registration fee) and go to the centre of town. Half an hour’s stroll will give you at least an impression of the city and you will not leave Vienna with the feeling that you have really only seen the conference centre.

Image of the Week – Ice on Fire (Part 2)

Image of the Week – Ice on Fire (Part 2)

This week’s image looks like something out of a science fiction movie, but sometimes what we find on Earth is even more strange than what we can imagine! Where the heat of volcanoes meets the icy cold of glaciers strange and wonderful landscapes are formed. 


Location of the Kamchatka Peninsula [Credit: Encyclopaedia Britannica]

The Kamchatka Peninsula, in the far East of Russia, has the highest concentration of active volcanoes on Earth. Its climate is cold due to the Arctic winds from Siberia combined with cold sea currents passing through the Bearing Strait, meaning much of it is glaciated.

Mutnovsky is a volcano located in the south of the peninsula, which last erupted in March 2000. At the base of the volcano are numerous labyrinths of caves within ice. The caves are carved into the ice by volcanically heated water. The roof of the cave shown in our image of the week is thin enough to allow sunlight to penetrate. The light is filtered by the ice creating a magical environment inside the cave, which looks a bit like the stained glass windows of a cathedral. It is not always easy to access these caves, but when the conditions are favourable it makes for a wonderful sight!

The Mutnovsky volcano is fairly accessible for tourists, around 70 km south of the city of Petropavlovsk-Kamchatsky. Maybe this could be the holiday destination you have been searching for?

Image of The Week – The Pulsating Ice Sheet!

Image of The Week – The Pulsating Ice Sheet!

During the last glacial period (~110,000-12,500 years ago) the Laurentide Ice Sheet (North America) experienced rapid, episodic, mass loss events – known as Heinrich events. These events are particularly curious as they occurred during the colder portions of the last glacial period, when we would intuitively expect large-scale mass loss during warmer times. In order to understand mass loss mechanisms from present-day ice sheets we need to understand what happened in the past. So, how can we better explain Heinrich events?


What are Heinrich Events?

During a Heinrich event large swarms of icebergs were discharged from the Laurentide Ice Sheet into the Hudson Strait and eventually into the North Atlantic Ocean. This addition of fresh water to the oceans caused a rise in sea level and a change in ocean currents and therefore climate.

We know about these events by studying glacial debris that was transported from the ice sheet into the oceans by the icebergs and eventually deposited on the ocean floor. From studying ocean-sediment records we know that Heinrich events occurred episodically during the last glacial period but not on at a regular intervals. Interestingly, when compared to temperature records from Greenland ice cores, it can be seen that the timing of Heinrich events coincides with the cold phases of Dansgaard–Oeschger (DO) cycles – rapid temperature fluctuations which occurred during the last glacial period (see our previous post).

the timing of Heinrich events coincides with the cold phases of Dansgaard–Oeschger (DO) cycles

What do we think causes them?

A new study, published last month in Nature, uses numerical modelling to show how pulses of warm ocean water could trigger Heinrich events. Our image of the week (Figure 1) illustrates the proposed mechanism for one event cycle:

  • a) Ice sheet at it’s full extent, grounded on a sill (raised portion of the bed, at the mouth of the Hudson Strait). Notice the sill is around 300m below sea level at this time.
  • b) A pulse of sub-surface water (purple) warms by a few degrees, encouraging iceberg calving at the glacier front and causing the ice begin to retreat from the sill.
  • c) As the ice retreats, it becomes unstable due to an inwards sloping bed (see our previous post on MISI). This leads to sudden rapid retreat of the ice – characteristic of Heinrich events.
  • d) Due to ice loss and thus less mass depressing the bed, the bed will slowly rise (Glacial Isostatic Adjustment), eventually the sill has risen to a level which cuts off the warmer water from the ice front and the ice can slowly advance again.

Once the ice has advanced back to it’s maximum extent (a) it will slowly depress the bed again, allowing deeper, warmer water to reach the ice front and the whole cycle repeats!

The authors of this study used this model to simulate Heinrich events over the last glacial period and were able to accurately predict the timing of Heinrich events, as known from ocean sediment records. Check out this video to see the model in action!!

Why is it important?

This study shows that the proposed mechanism probably controlled the onset of rapid mass-loss Heinrich events in the past and more generally that such mechanisms can cause the rapid retreat of marine terminating glaciers. This is important as it adds to our understanding of the stability (or instability) of present day marine terminating glaciers – such as the West Antarctic Ice Sheet! If such rapid mass loss happened regularly in the past we need to know if and how it might happen in the future!

such mechanisms can cause the rapid retreat of marine terminating glaciers.
