Happy blog birthday!

Happy blog birthday!

Can you believe it, people? We have been running this blog for 2 years! What a milestone! Time to celebrate and look back at a year of great blogging.

Who are the champions?

We are the champions, my friends!

That’s right! We actually won a prize this year: we won best blog post of 2018 by public vote for a post by one of our editors, Luca Dal Zilio, about a conference he attended in Singapore. So we are now an award-winning blog. Hell yeah!
Technically this post was written during our first blog year, but hey, we only got the prize in January, so I think we’re totally within our rights to mention it now. Since we won by public vote, we would like to thank all of you – our readers – for your support! It really means a lot to us and strengthens the idea that some people actually read this blog!

And talking about our readers…

Who are you?

Contrary to popular belief, there are actually people who read this blog! Although I don’t have any data to back this up, I think most of our readers are actually scientists from the geodynamics, tectonics and structural geology, and seismology divisions of EGU. So much for trying to do outreach. If I’m wrong, please let me know!
I do have some data on how many people visit our blog. On average, we have 37 unique visitors per day (and that’s quite something if you remember that we only post on Wednesdays and now Fridays). Our 100 most viewed pages (and this includes the homepage, author profiles, tags, etc. as well as individual posts) each have seen 150 unique visitors on average with some posts having over 2000 unique visitors in the past year! These popular posts are usually commissioned and promoted on social media by our editor Grace Shephard. Little gems of blog posts with many views from her hand include The Rainbow Colour Map (repeatedly) considered harmful, Thirteen planets and counting, and How good were the old forecasts of sea level rise?

We have a global readership! Most of our readers are accessing the website from the US, the United Kingdom, Germany, China, and Spain. Interesting list of countries, right? Apart from that, we also have some geodynamicists in Turkmenistan, Rwanda, Pakistan, Myanmar, and Mozambique. Or maybe that is just a result of geodynamicists being on holiday in exotic places who are dying to read geodynamics news to distract themselves from their amazing holiday destination. Who knows?

Who are we?

We have a lovely blog team and it’s quite a big team as well! Currently, there are 7 regular editors, one mysterious, anonymous editor under the name of ‘The Sassy Scientist’ and one Editor-in-Chief (yours truly). Who would’ve ever thought there would be 9 people in the blog team? Last year, we were 5, so we have grown a lot. If you have already forgotten who we are, you can check out our recent introduction post.

But, these 9 amazing editors don’t have the time (or the expertise) to write all these blog posts themselves. Therefore, we heavily rely on the most amazing guest authors. During the past year, we had 20 guest authors who contributed one or more posts. So here is a big shout out to all the guest authors of the past year:

• Manar Alsaif
• Marie Bocher
• Daniel Bowden
• Kiran Chotalia
• Robert Citron
• Lorenzo Colli
• João Duarte
• Rene Gassmöller
• Lars Gebraad
• Antoniette Greta Grima
• Charitra Jain
• Kirster Karlsen
• Maria Koroni
• Laurent Montesi
• Andrea Piccolo
• Adina Pusok
• Nico Schliffke
• Paul Tackley
• Katy Willis
• Jonny Wu

Thank you so much. We couldn’t do it without you!

Behind the scenes

During our first 1.5 years of blogging we had a system in place where we had regular types of posts, such as Geodynamics 101, Remarkable Regions, Peculiar Planets, and Wit & Wisdom posts. Additional content that did not fit in any of these categories, would go into our News & Views or Conferences. This meant that all the editors were encouraged to find posts that fitted into a certain topic and then we hoped for the best. In practice, most of the responsibility lay with yours truly: the Editor-in-Chief. I was in charge of keeping an eye on the schedule and asking the editors to contribute. In the end, I wrote and commissioned most of the posts myself.

That was clearly unsustainable.

Whenever I had a lapse of vigilance, holes were more likely to appear in the schedule, because no one else in the blog team felt responsible for posting (and rightfully so). This lead to the infamous gaps in content around February (which seems to be a recurring yearly theme).

Again: clearly unsustainable.

So. This year, I got inspired at the EGU Blog Editor meeting a few days before the General Assembly and I thought of a complete new blog strategy during EGU. I know: I spent my time at EGU wisely…

We recruited a bunch of new editors and we have now successfully implemented a new schedule: all 7 regular editors are responsible for a blog post for 1 week in a 7 week cycle. They can commission blog posts, write them, give their slot to another editor who might have more blog posts lined up, or whatever they want to do, but they are – in the end – responsible for uploading a blog post on Wednesday. I still keep an eye on the schedule and fill gaps where necessary, but at least now I have someone to address whenever there seems to be an empty slot. We also added some extra repercussions to increase the responsibility of our regular editors: if they fail to upload a Wednesday blog post on time in their scheduled weeks twice within one year, they will automatically stop being editors. Of course, we want to keep everyone in the team, so everyone is encouraged to help each other out, if a gap in the schedule threatens to appear.
The Sassy Scientist is responsible for weekly Friday Q&As, which is a lot of work actually: 52 blog posts in a year is a lot. So for these posts, we are working with a backlog of at least 5 blog posts at all times to ensure that our Sassy Scientist can sometimes take a holiday. Currently, I am editing all the Sassy Scientist blog posts, but I’m hoping they can fly solo soon! One of the most difficult things is getting questions for the Sassy Scientist to answer. So far most of the questions have been asked by editors, although some wished to remain anonymous, so their names were changed. Therefore, we ask everyone to just e-mail the Sassy Scientist a question, leave a comment to one of the blog posts or on social media. You will remain anonymous, if you so desire, and we will make sure that your question gets answered soon (i.e., we will adapt the schedule accordingly).
The new system works well so far. Let’s see if we can keep it up!

So now what?

Well, onwards and upwards, don’t you think? We will try to keep providing you with geodynamics news on Wednesdays and Sassy Scientist Q&As on Fridays for another year. That’s twice as much content as in our first year! Theoretically. We have lots of great posts lined up as well as some very impressive, new guest authors who are dying to pen down their thoughts. If you would like to contribute to the blog, don’t hesitate to contact us by sending us an e-mail. Until then: enjoy the read!

Introducing the blog team!

Introducing the blog team!

It’s time for another proper introduction of the blog team! As you will probably know, things have been a bit silent on the blog front lately. This is because all the blog editors were very busy and also: it’s hard to upload 52 times a year. You come up with some great blog ideas! (if you do: e-mail us, please!). Luckily, we used the EGU General Assembly to find some fresh blood for the blog team. Together with the seasoned blog team members and a new blog strategy, we are buzzing to give you regular content once again. Expect the usual blog posts on Wednesday at 9:00 am and in the future, maybe expect a little extra on Fridays… But who are these great people providing you with your weekly dose of geodynamics news?

The Blog Team

Iris van Zelst
I am a PhD student in the Seismology and Wave Physics group at ETH Zürich, Switzerland. I am right at the seismology border of geodynamic research, as I am combining geodynamic modelling with dynamic rupture modelling to look at earthquakes in subduction zones on the entire timescale relevant to the process. I also occasionally look at some data, because you should always keep it real. I am in the final year of my PhD (oh help!), so my aim as Editor-in-Chief is to make sure everyone else is organised and uploading regularly, while I will be mostly pulling the strings behind the scenes and writing an occasional blog post. Such as this one! In my spare time, I love to read lots of books in all kinds of genres, go to the theatre, and play a little bit of theatre myself. I recently enrolled in an improv class and it is so much fun! All the world’s a stage. You can reach my via e-mail.

Luca Dal Zilio
I am a postdoctoral researcher in Mechanical Engineering and Geophysics at the California Institute of Technology (Caltech). My research is primarily aimed at understanding the relationship between crustal deformation and earthquakes in mountain belts, such as the Alps and Himalaya. By combining theoretical, computational, and observational approaches, I attempt to understand the interplay between geodynamic space–time scales of millions of years of slow and broadly distributed regional deformation with seismic space–time scales of rapid and localised earthquake processes. My passion lies in democratising science communication via innovative and accessible tools in order to spread scientific research and discovery. And yes, I like coffee. Espresso. You can reach me via e-mail.

Anne Glerum
I am a postdoctoral researcher at GFZ Potsdam, Germany. With numerical models, I investigate the link between local stress and strain observations and far-field forcing in the East African Rift System. Other modelling interests include magma-tectonic feedback and surface evolution during continental extension. Outside of research, I love to go on walks with my dog, to explore my new home Berlin and to read books on all possible topics. I’m excited to show you the variety of geodynamics and its overlap with other disciplines as an editor of the GD blog team. You can reach me via e-mail.

Anna Gülcher
I am a PhD student at the Geophysical Fluid Dynamics group at ETH Zürich, Switzerland. With the use of numerical modelling, I study the interior dynamics of the Earth and other planets. For my research, I am trying the put geophysical, geological, and geochemical observations in a geodynamically coherent framework (with an emphasis on trying). I found a passion for windsurfing early on while still living in my flat home country (the Netherlands). Yet, since moving to mountainous Switzerland, I have traded in my windsurfing equipment for hiking boots or snowboarding gear and try to spend my free time in the Alps to seek some adrenaline. I’ve very recently started to learn how to play the guitar, and am very proud to say that I can now play my very first complete song. I am excited to be part of the GD team as an Editor! You can reach me via e-mail.

Diogo Lourenço
I am a postdoctoral researcher at the Department of Earth and Planetary Sciences at the University of California Davis, USA. My research aims at understanding the evolution and interior dynamics of the Earth and other rocky planets, primarily through the use of numerical models. When I am not working on theoretical geodynamics, I like to keep things theoretical. I like reading and playing music. Sometimes I also exercise by walking around museums and looking at things. With my work as an editor in this blog, I hope to bring geodynamics to the reader in a friendly and exciting way. I also hope to help building a more involved and integrative geodynamics community. You can reach me via e-mail.

Tobias Meier
I am currently a PhD student at the Center for Space and Habitability (CSH) at the University of Bern. My research focuses on understanding the interior dynamics of rocky exoplanets, particularly planets that are partly molten. At the CSH, Earth and planetary scientists and astrophysicists work side-by-side to understand the formation and evolution of solar system bodies and exoplanets. As an editor of the GD blog I will nurture the link between geodynamics and terrestrial planet evolution and foster interactions between related disciplines.
As an undergraduate I worked in the field of cosmology, so it was necessary for me to downsize from thinking about the vast scales of the universe to zooming in on individual planets when I transitioned to my PhD work. At the time of writing, there has not been a confirmation of an inhabited exoplanet where we could possibly travel to. So, on our own wonderful planet, I enjoy hiking in the beautiful Swiss mountains and I also (almost) never say no to a game of table tennis. You can reach me (also for table tennis!) via e-mail.

Antoine Rozel
I am a senior researcher in ETH Zürich. After studying physics (nobody is perfect), I have been working on numerical simulations of mantle convection involving absurd rheologies for quite a while now, I am getting old. I am also interested in crust and craton production in all solar system planets. To make life even more beautiful, I have also finished the conservatory in classical piano and I organised some painting exhibitions in the last years (you can find my gallery here). I have also found recently that -when I do not play pinball or videogames- I can save time by doing both music and sport at the same time by playing Japanese drums (taiko)! You can reach me via e-mail.

Grace Shephard
I am a Researcher at the Centre for Earth Evolution and Dynamics (CEED) at the University of Oslo, Norway. My research links plate tectonics,​ palaeogeography, and deep mantle structure and dynamics. I spend much of my time hunting for evidence to constrain the opening and closure of ocean basins, particularly around the Arctic, Atlantic and the Pacific. I think GPlates is an excellent Tardis with which to time travel. Geodynamics offers a lot of interdisciplinary and creative avenues to explore – and why not follow up your idea with a blog post! You can reach me via e-mail or find a sporadic tweet at @ShepGracie.

The Sassy Scientist
I am currently employed at a first tier research institute where I am continuously working with the greatest minds to further our understanding of the solid Earth system. Whether it is mantle or lithosphere structure and dynamics, solid Earth rheology parameters, earthquake processes, integrating observations with model predictions or inversions: you have read a paper of mine. Even if you are working on a topic I haven’t mentioned here, I still know everything about it. Do you have any problems in your research career? I have already experienced them. Do you struggle with your work-life balance? Been there, done that. Nowadays, I have only one hobby: helping you out by answering the most poignant questions in geodynamics, research, and life. I am waiting for you right here. Get inspired.

A belated happy new year!

A belated happy new year!

It was that time of the year again: holidays! Time to take a break from work, relax, and see all your friends and family again. The blog team is no different: we took a break from blogging for a little while as well, so you had to survive the holidays without us! Did you survive Christmas day without one of our blogposts? It must’ve been dreadful, I know, but that’s life! Luckily, we have some good news: we are back with some belated happy new year wishes and wintersport recommendations. We also tried to write limericks. Also also, we discuss chocolate and peppermint. Because we can. Cheers to a good blog year in 2019! 

Iris van Zelst

I once tried to ski down a slope
as friends thought there might be hope
I was covered in snow
from my head to my toe
If they invite me again it’s a ‘nope’

So, as many of you might have guessed, winter sports (or any sports, really) are not entirely my thing. Particularly skiing did not go down well for me. However, as a true Dutch girl, I do really enjoy ice skating and can recommend it thoroughly! However, this year no winter sports at all for me: I flew towards the sun in an effort to actually destress from work (feeble attempt as I brought my laptop, but still, kudos for trying, right?). I hope everyone had a very nice holiday and relaxing break. May all your (academic) wishes come true in 2019!

I also tried cross-country skiing once. That was infinitely better than alpine skiing. It was actually fun!

Grace Shephard

In hemispheric defiance of the “wintersport” edition, I am currently back Down Under where I have replaced the (seemingly eternal) television coverage of cross-country skiing with cricket, swapped a toboggan for me ‘togs’, and exchanged a pull-over for some ‘pluggers.’ I wish all of our blog readers a very happy and safe end to the year that was, and a fabulous start to the next!

Anne Glerum

This year I spend winter in Berlin,
Where no snow has fallen and the ice is too thin.
So I drink myself heavy,
With hot chocolate and Pfeffi,
And wait for the fresh air of spring!

In the weeks before Christmas, Christmas markets dominate the streets of Berlin. Besides delicious food, they offer mulled wine and, as I discovered this year, hot chocolate with peppermintliqueur. A green version of the liqueur is made by Pfeffi, while a colorless Berlin-made peppermintliqueur is called Berliner Luft. It’s as clear and fresh as Berlin’s air according to the manufacturer. Although the freshness of Berlin’s air is debatable, the combination of chocolate and peppermint is delicious. I wish everybody a fresh start of the New Year with loads of hapiness!

Holiday recommendations – blog break summer 2018

Holiday recommendations – blog break summer 2018

Even dedicated workaholics such as the editors of your EGU GD Blog Team sometimes deserve a break! Let me clarify that by saying ‘an intentional break’ (because uploading every Wednesday is hard!). We will be ‘on holiday’ during August, so there won’t be any new blog posts then. But don’t worry: we will be back stronger than ever in September and we already have a lot of very good blog posts in the pipeline for you. To start the holidays properly and to get you in the holiday spirit as well, the EGU GD Blog Team shares their geodynamical holiday recommendations with you. Enjoy & relax!

Iris van Zelst – Edinburgh

Hutton’s Section with a very young me (in 2012) for scale

Go. To. Edinburgh. Seriously: Edinburgh is the place to be for anyone who has an affinity with the Earth sciences. In this beautiful, historic city, James Hutton – the founder of modern geology, who originated the idea of uniformitarianism – lived and died. Everywhere in the city you can find little reminders indicating this iconic scientist lived there. You could, for example, visit his grave, and hike to his geological section on Edinburgh’s Salisbury Crags. There are also little plaques spread around the city that mark significant James Hutton places and events. The city itself is also steeped in a mix of geology and history: Edinburgh Castle, situated on the impressive volcanic Castle Rock, boasts an 1100-year-old history and towers over the city. Directly across from the castle, connected by the charming Royal Mile is Holyrood Palace, where you can soak up even more history – Mary Queen of Scots lived here for a while. Nearby, there is Holyrood Park where you can find the group of hills that hosts Hutton’s Section and a 350 million year old volcano named Arthur’s Seat. Climb it when the weather is nice and you will have the most amazing view of Edinburgh. The whole park is perfect for day hikes and picknicks.
Even if you (or your travel buddy) are not that into Earth Sciences (or history), Edinburgh has plenty of other attractions. It is the perfect place for book and literature lovers with the large International Book Festival every August and a very rich literary history with iconic writers such as Walter Scott (Ivanhoe), Robert Louis Stevenson (Strange Case of Dr Jekyll and Mr Hyde; Treasure Island), Arthur Conan Doyle (Sherlock Holmes), and – more recently – J. K. Rowling (Harry Potter). Theatre fans will also love Edinburgh, particularly during August when it hosts the Edinburgh Festival Fringe – the largest arts festival in the world.
I totally should’ve booked a trip to Edinburgh this year… Learn from my mistakes and enjoy it in my stead!

The view of Edinburgh when you’re standing on top of Arthur’s Seat: a more than 300 million year old volcano. Pretty epic.
Picture by me in 2012 (also: proof that the weather can be good in Scotland!)

Luca Dal Zilio – Aeolian Islands

My recommendation? I vote for the Aeolian Islands! Smouldering volcanoes, bubbling mud baths and steaming fumaroles make these tiny islands north of Sicily a truly hot destination. This is the best place to practice the joys of “dolce far niente“: eat, sleep, and play. The Aeolian Arc is a volcanic structure, about 200 km long, located on the internal margin of the Calabrian-Peloritan Arc. The arc is formed by seven subaerial volcanic edifices (Alicudi, Filicudi, Salina, Lipari, Vulcano, Panarea, and Stromboli) and by several volcanic seamounts which roughly surround the Marsili Basin. The subduction-related volcanic activity showed the same eastward migration going from the Oligo-Miocene Sardinian Arc to the Pliocene Anchise-Ponza Arc and, at last, to the Pleistocene Aeolian Arc. My favourite island, Stromboli, is one of the few volcanoes on earth displaying continuous eruptive activity over a period longer than a few years or decades. I like Stromboli because it conforms perfectly to one’s childhood idea of a volcano, with its symmetrical, smoking silhouette rising from the sea. Most of this activity is of a very moderate size, consisting of brief and small bursts of glowing lava fragments to heights of rarely more than 150 m above the vents. Occasionally, there are periods of stronger, more continuous activity, with fountaining lasting several hours, violent ejection of blocks and large bombs, and, still more rarely, lava outflow. I can’t quite explain what made it so special to me. It may be because Stromboli itself is an island, and all the time during the hike I enjoyed splendid sea views (with a beer in my hand). It may be the all encompassing experience, where I could see, hear and literally feel the lava explosions. It was simply fantastic.

Anne Glerum – Montenegro

In case you don’t make it to Montenegro/Serbia this summer, it’s fun in winter too. And yes, it’s fun in spring too – there’s snow, mountains and a younger me on a tiny sled. Photo courtesy of Cyriel de Grijs

My geo-holiday-destination: Montenegro!
A summer without beach-time is not a summer to me (already got one beach-day in this year, phew). Being Dutch, a proper holiday also requires some proper mountains – or hills at least. And no trip is complete without cultural and culinary highlights to explore.
Montenegro is a country that ticks all the boxes. Situated along the Adriatic Sea it hosts a score of picture-perfect beaches; quiet or taken over by the jet-set, intimate coves or long stretches of white sand, take your pick.
Further inland, you reach the Dinarides orogenic chain, the product of 150 My of contractional tectonics and later collapse during the Miocene. Traversing the chain into neighboring Serbia will lead you past complete ophiolite sequences, syn-orognic magma intrusions and major detachment zones of the extensional orogenic collapse.
Visit the centuries old fortified coastal cities of Budva or Kotor or one of the many churches and frescoed monasteries spread around the countryside. For more bodily sustenance, enjoy the fresh fish dishes, rich meats or the regional cheeses and yoghurts. Seasonal fruits are eaten for dessert or, even better, turned into wine and rakija. Ehm, why I am not going there again this year – this time in summer?

Diogo Lourenço – CIDER Summer School

This year, my favourite geodynamical destination is CIDER 2018! It’s far from holidays… but it’s really cool! For the last three weeks (one week to go), we have been intensely learning about heterogeneity in the Earth, and trying to understand it in an interdisciplinary perspective with contributions from geochemistry, geodynamics, and seismology. Quite an intense schedule and a lot of information to process, but I think we are all learning a lot, and hopefully in the future we will use more constraints coming from other fields into our own work. Oh, and did I mention that it is happening in Santa Barbara? Great Californian weather, beautiful coastal landscapes, barbecues by the beach, and swimming in the ocean, all sprinkled with scientific discussions! Quite the geodynamical destination, no?

Just had to cross the street from the KITP building where the conference is happening to take this photo…

Grace Shephard – Svalbard

Geoscientists are no strangers to travelling to exotic places and many of us take the opportunity to turn a work-related trip into potential holiday scouting. My suggested destination is most probably the northernmost point you can quite easily travel to on this planet – Svalbard.
Svalbard is an Arctic archipelago located around between 74-81°N latitude. It is sometimes confused with Spitsbergen, which is actually the name of the largest island where the main settlements, including Longyearbyen and Barentsburg, are situated. The islands are part of Norwegian sovereignty, though with some interesting taxation and military restrictions (the Svalbard Treaty of 1920 makes for some pretty interesting reading). Svalbard is host to a stream of tourists and scientific researchers year-round, and this week I will travel back to Longyearbyen as a lecturer for an Arctic tectonics, volcanism and geodynamics course at the University Centre in Svalbard (UNIS).
Geologically speaking, Svalbard makes for a very interesting destination. It offers a diverse range of rock ages and types; having experienced orogenic deformation events, widespread magmatism, and extensive sedimentary and glacial processes.
If you’re after a more usual tourist package amongst the draw cards are of course iconic polar bears (though please keep your distance), stumpy reindeer, arctic foxes, whales, birds and special flora. There are many glaciers – in fact around 60% of Svalbard is covered in ice – as well as fjords and mountains, former coal mining settlements… the list goes on. You are even spoilt for choice between midnight sun or midday darkness, depending on the time of year, so prioritise your activities wisely. Plus, did I mention those miles and miles of unvegetated, uninterrupted rock exposures to keep any geology enthusiast happy?… if you’re lucky you might come across some incredible fossil sites.

Itinerary recommendation, tried and tested: Whale watching and fjord cruising to a Russian mining ghost town (Pyramiden) followed by an important sampling of the world’s northernmost brewery.
