Image of the Week — Hidden lakes in East Antarctica !

Image of the Week — Hidden lakes in East Antarctica !

Who would have guessed that such a beautiful picture could get you interviewed for the national news?! Certainly not me! And yet, the photo of this englacial lake (a lake trapped within the ice in Antarctica), or rather science behind it, managed to capture the media attention and brought me, one of the happy co-author of this study,  on the Belgian  television… But what do we see on the picture and why is that interesting?


Where was the picture taken?

The Image of this Week shows a 4m-deep meltwater lake trapped 4 m under the surface of the Roi Baudouin Ice Shelf (a coastal area in East Antarctica). To capture this shot, a team of scientists led by Stef Lhermitte (TU Delft) and Jan Lenaerts (Utrecht University) went to the Roi Baudouin ice shelf, drilled a hole and lowered a camera down (see video 1).

How was the lake formed?

In this region of East Antarctica, the katabatic winds are very persistent and come down from the centre of the ice sheet towards the coast, that is the floating ice shelf (see animation below). The effect of the winds are two-fold:

  1. They warm the surface because the temperature of the air mass increases during its descent and the katabatic winds mix the very cold layer of air right above the surface with warmer layers that lie above.
  2. They sweep the very bright snow away, revealing darker snow/ice, which absorb more solar radiation

The combination leads to more melting of the ice/snow in the grounding zone — the boundary between the ice sheet and ice shelf — , which further darkens the surface and therefore increases the amount of solar radiation absorbed, leading to more melting, etc. (This vicious circle is very similar to the ice-albedo feedback presented in this previous post).

All the melted ice flows downstream and collects in depressions to form (sub)surface lakes. Those lakes are moving towards the ocean with the surrounding ice and are progressively buried by snowfalls to become englacial lakes. Alternatively, the meltwater can also form surface streams that drain in moulins (see video 2).

Why does it matter ?

So far we’ve seen pretty images but you might wonder what could possibly justify an appearance in the national news… Unlike in Greenland, ice loss by surface melting has  often been considered negligible in Antarctica. Meltwater can however threaten the structural integrity of ice shelves, which act as a plug of the grounded ice from upstream. Surface melting and ponding was indeed one of the triggers of the dramatic ice shelves collapses in the past decades, in the Antarctic Peninsula . For instance, the many surfaces lakes on the surface of the Larsen Ice shelf in January 2002, fractured and weakened the ice shelf until it finally broke up (see video 3), releasing more grounded ice to the ocean than it used to do.

Of course surface ponding is not the only precondition for an ice shelf to collapse : ice shelves in the Peninsula had progressively thinned and weakened for decades, prior their disintegration. Our study suggests however that surface processes in East Antarctica are more important than previously thought, which means that this part of the continent is probably more vulnerable to climate change than previously assumed. In the future, warmer climates will intensify melt, increasing the risk to destabilise the East Antarctic ice sheet.

  • We also launched our new “for dummies” category that aims at explaining complex glaciological concepts in simple terms. The first and most read “for dummies” is all about “Marine Ice sheet instability” and explains why West Antarctica could be destabilised.

Marine Ice Sheet Instability [By D. Docquier].

Three other “for dummies” have been added since then. They unravel the mysteries behind Water Masses, Sea Level and Ice Cores.

  • Drilling an ice core [By the Oldest Ice PhD students]

    Another welcomed novelty of 2016 was the first “ice-hot news” post, about the very exciting quest for the oldest ice in Antarctica. In this post — issued at the same time as the press release —  the 3 PhD students currently involved with the project explain how and where to find their holy grail, i.e. the 1 million year old ice!

The list goes on of course, and I could probably spend hours presenting each of our different posts one by one and explain why every single one of them is terrific. Instead, I have decided to showcase a few more posts with very specific mentions!

Good resolutions for 2017

The beginning of a new year is a great opportunity to look back at the previous year, and one of the logical consequences is to come with good resolutions for the coming year.  Thinking of a good resolution and then achieving it can however be tricky.  This is why we have compiled a few resolutions, that YOU dear cryo-followers could easily make 🙂

 Cryoblog stronger in the E(G)U blog competition

To celebrate the excellent display of science writing across all the EGU blogs, a competition has been launched.

Olaf the snowman begs you to vote for “the journey of a snowflake”

From now until Monday 16th January, we invite you, the cryo-readers, to vote for your favourite post of 2016, which should be “journey of a snowflake” (second-to last option). I am obviously being totally objective but if you’re not convinced, the little guy on the right might be more persuasive. If you’re really adventurous, you could also consider clicking on other posts to check what they look like, after having voted for the cryo-one, of course.

Get involved

Hopefully by now:

  1. You are convinced that the cryosphere is amazing and that the EGU cryoblog enables you to seize some of the cryo-awesomeness
  2. You have read and elected the “journey of a snowflake”  as the best post of 2016
  3. You would like to contribute to the blog (because you would like to be part of this great team or simply because you think your sub-field is not represented well enough).

Not to confuse you with a long speech, the image below explains how to get involved. We always welcome contributions from scientists, students and professionals in glaciology, especially when they are at the early stage of their career.

Thank you for following the blog!

PS: this is one of my favourite tweets from the EGU cryospheric division twitter account. What is yours?

Image of the Week – Climate Change and the Cryosphere

Image of the Week – Climate Change and the Cryosphere

While the first week of COP22 – the climate talks in Marrakech – is coming to an end, the recent election of Donald Trump as the next President of the United States casts doubt over the fate of the Paris Agreement and more generally the global fight against climate change.

In this new political context, we must not forget about the scientific evidence of climate change! Our figure of the week, today summarises how climate change affects the cryosphere, as exposed in the latest assessment report of the Intergovernmental Panel on Climate Change (IPCC, 2013, chapter 4)


Observed changes in the cryosphere

Glaciers (excluding Greenland and Antarctica)

  • Glaciers are the component of the cryosphere that currently contributes the most to sea-level rise.
  • Their sea-level contribution has increased since the 1960s. Glaciers around the world contributed to the sea-level rise from 0.76 mm/yr (during the 1993-2009 period) to 0.83 mm/yr (over the 2005-2009 period)

Sea Ice in the Arctic

  • sea-ice extent is declining, with a rate of 3.8% /decade (over the 1979-2012 period)
  • The extent of thick multiyear ice is shrinking faster, with a rate of 13.5%/decade (over the 1979-2012 period)
  • Sea-ice decline sea ice is stronger in summer and autumn
  • On average, sea ice thinned by 1.3 – 2.3 m between 1980 and 2008.

Ice Shelves and ice tongues

  • Ice shelves of the Antarctic Peninsula have continuously retreated and collapsed
  • Some ice tongue and ice shelves are progressively thinning in Antarctica and Greenland.

Ice Sheets

  • The Greenland and Antarctic ice sheets have lost mass and contributed to sea-level rise over the last 20 years
  • Ice loss of major outlet glaciers in Antarctica and Greenland has accelerated, since the 1990s

Permafrost/Frozen Ground

  • Since the early 1980s, permafrost has warmed by up to 2ºC and the active layer – the top layer that thaw in summer and freezes in winter – has thickened by up to 90 cm.
  • Since mid 1970s, the southern limit of permafrost (in the Northern Hemisphere) has been moving north.
  • Since 1930s, the thickness of the seasonal frozen ground has decreased by 32 cm.

Snow cover

  • Snow cover declined between 1967 and 2012 (according to satellite data)
  • Largest decreases in June (53%).

Lake and river ice

  • The freezing duration has shorten : lake and river freeze up later in autumn and ice breaks up sooner in spring
  • delays in autumn freeze-up occur more slowly than advances in spring break-up, though both phenomenons have accelerated in the Northern Hemisphere

Image of the Week — ice tsunamis !

Image of the Week — ice tsunamis !

Tsunami is a word that became world famous after the so-called Christmas tsunami in 2004, when enormous waves hit the shores around the Indian Ocean with disastrous consequences for countries such as Sri Lanka, Thailand, Somalia and many others.

But did you know that tsunamis can be icy?

An ice tsunami is one of the many names associated with ice shoves (or ivu, shore ice override, ice pile-up, ice ride-up). This rare but impressing phenomenon happens when strong winds rapidly push slabs of sea/lake ice towards the shore.

  • Once on shore, the ice shoves can ride up and advance up to a few hundreds metres inland as a large but thinner sheet of ice (Mahoney et al, 2004; Whiteman, 2011)

  • Alternatively, the ice slabs can also pile up, forming a big ridge on the beach that can rise up to 200m high (Mahoney et al, 2004; Whiteman, 2011).

 

Conditions to get an ice shove

  1. Partial thaw: Ice shoves can only happen when the ice has started to melt but has not completely disappeared yet.  Spring is therefore the best time of the year to observe such a phenomenon.
  2. Strong winds: Only strong winds in the direction of the shore can push piles of ice ashore.
  3. Gentle slope of the beach: The gentler the slope of the shore, the less it prevents the ice pile to advance inland, and the more it can pile up.

This is a common phenomenon in Northern Canada and in Alaska but as these places are sparsely populated, the damages it causes are often limited.

Image of the Week — Where do people stay in the “coolest” place on earth?

What word would you use to characterise the Antarctic ?

White?
Windy?
Remote?
Empty?
Inhospitable?
Wild?
Preserved?

While all of these are true it may surprise you to find out that the Antarctic is occupied by humans all year round with almost half of its 82 research stations operating 365.25 days a year!

Just a few hours before the launch of the biennial Antarctic meeting held by the Science Committee on Antarctic Research (SCAR) in Malaysia, we thought it would be perfect timing to check out who is leading research in Antarctica and where…

…but before that let’s have a look first at what makes Antarctica so special!


Antarctica, a very peculiar continent, regulated by the Antarctic treaty

Antarctica is regulated by the Antarctic Treaty that defines this continent as a “natural reserve, devoted to peace and science” (Environmental Protocol, 1991). This means that since the treaty came into force in 1961:

  • the Antarctic environment is fully protected
  • the land doesn’t not belong to any country because the treaty pauses existing territorial claims in Antarctica, as long as it stays in force
  • Antarctica has been demilitarised and no nuclear tests are allowed
  • International collaboration in the name of progressing scientific research is encouraged, with many countries with greater operational capacity aiding those with little or none to allow them to conduct research.

Who is conducting research in Antarctica and where?

The map above shows the 82 permanent research stations dotted across the Antarctic. Among those bases, 40 are operated all year long while the others only host scientific research during the Austral summer (November-February). The location and capacity of these stations also varies considerably from one to another. For instance, the US McMurdo station – the biggest scientific base in Antarctica – is settled on an island and is open all year-ong, accommodating up to 1,000 people during summer. On the contrary, a small seasonal station such as the Belgian Princess Elisabeth Station is only open during the summer and can host up to 20 people.

The research supported by these scientific stations is very broad and covers topic as diverse as sea level rise, climate change, observation of space, biodiversity, etc… Much of this happens in the austral summer when field parties are able to travel from the research stations into even more remote areas of the continent to conduct experiments and install equipment. However, some science, such as meteorology and weather observations takes place all year round no matter how cold, windy and inhospitable the continent may be for those conducting the research.

This is the case of the two “brave” GPSes of Tweetin ice shelf project, which are installed on an ice shelf and tweet their position and movement all year long (you can follow them on @TweetinIceShelf).

Antarctic (stations) fun facts

  •  1 is the number of station operated by an African country : SANAE IV (South Africa)
  • 13 stations is the maximum for one single country (Argentina)
  • -89.2°C is the coldest temperature ever recorded on earth. It was at an Antarctic Station:  Vostok (Russia)
  • 1904 is the opening date of the oldest station still in activity: Orcadas (Argentina)
  • 2014 is the opening date of the youngest station : Jang Bogo (Republic of Korea)
  • 1,000 people is the maximum number of people that a station can accommodate : Mc Murdo (USA)
  • 4087 m is the elevation of the highest station : Kulun (China)
  • 8 is the number of Pokemon Go currently pinpointed in the Antarctic 😀

Here are the countries with at least one scientific base in Antarctica, does yours belong to this list?

Image of the Week — Arctic porthole, Arctic portal

No need to be a superhero to momentarily escape your everyday life!
For that you, can just rely on the EGU Cryosphere Blog, which cares for taking you on trips to all sorts of remote and cool places (OK, OK we have to admit that some of these places are indisputably cold 🙂).

The picture of this week was taken through the porthole of a boat in the middle of Isfjorden, one of the largest fjord in Svalbard .

What is Svalbard and why should we care about it?

Svalbard is not only the mythical home of Phillip Pullman’s armoured bears but it also an archipelago (island cluster) north of Norway, in the Arctic circle. 60 % of its surface is covered by glaciers (1615 in total) which hold enough ice to raise global sea level by 19mm. These glaciers are very varied, covering a wide range of different ice dynamic types. For example – you can find tidewater glaciers (terminating at floating ice shelves in the sea), surging glaciers (which experience cycles of rapid speed-up and slow-down) and ice caps (on the Eastern Islands).

Svalbard is a place for adventurous cryospheric fieldwork related on this blog and the subject of much scientific study, but here are a few reason why this place is significant:

  • Enhanced warming is currently occurring in the Arctic as a result of polar amplification.
  • The glaciers and ice caps in Svalbard are currently losing 5 ± 2 Gigatons of ice per year (IPCC, 2013).
  • Despite its very northern latitude (74° to 81° north), the climate in Svalbard is relatively warmer than in other islands at the same latitude. This due to the influence of the warm north Atlantic current that, in the winter, warm Svalbard up to 20°C, compared to its Russian and Canadian Arctic counterparts.

Does anyone live there?

It may surprise you to know that the Svalbard area counts more polar bears (~3500) than people living there (~2,650) ! Being sparsely populated, however, doesn’t prevent the Archipelago from having human activities such as coal mining, tourism and scientific research.

Image of the Week – Mushrooms at zero degrees = hair ice?!

Image of the Week – Mushrooms at zero degrees = hair ice?!

 

When you go down to the woods today you’re in for a big surprise….. hair ice! 

Did you know that there is a type of ice called hair ice? It is shaped like fine, silky hairs and looks like white candy floss. It grows on the rotten branches of broad-leaf trees during humid winter nights when the air temperature drops slightly below 0°C. A 100-year-old theory states that hair ice also needs something else to grow – a fungus – but, until recently, no one had managed to confirm this.

A team of scientists (a physicist, a chemist and a biologist) in Germany and Switzerland have now identified the missing ingredient – the fungus Exidiopsis effusa – after performing a series of experiments (Hofmann et al, 2015).

The biologist, Gisela Preuß, studied samples of hair-ice wood under the microscope and discovered that all of them were home to Exidiopsis effusa. If the fungus was missing or its activity stopped by fungicide or hot water, the hair ice would be missing too. The physicist, Christian Mätzler, studied the physical mechanism that makes hair ice grow in such fine strands. He discovered that the shape of the ice is due to the internal structure (rays) of the wood and growth of the fungus, which together prevent the ice from forming large crystals at the wood surface. The chemist, Diana Hofmann, studied the hair ice itself and identified natural substances produced by the fungus – lignin and tannin – that allow the hair ice to keep its hairy shape for a long time. This collaboration between scientists from different fields really shows the power of putting your heads together!

It took 100 years to confirm the theory because hair ice is rare and hard to spot: it mostly forms during the night, melting when the sun rises.

So…keep an eye out next time you go for an early morning walk in the woods. If you can find hair ice, you are in for a treat!

Image of the Week — Glowing Ice

Image of the Week — Glowing Ice

Two weeks ago, the EGU General Assembly was coming to an end in Vienna. With over 16,500 participants, this year’s edition was bigger and more varied than ever (e.g check out this good overview of the science-policy short course, published 2 days ago on geolog). The week was particularly fruitful for the cryospheric sciences and to mark this we have cherry-picked one of the winning picture of the EGU photo contest 2016 as our image of this week. It’s great that an image of the cryosphere is a winner in this competition and we are pleased to see that it isn’t only us that go bananas for pictures of ice!

What do we see?

The beautiful shot shows a stranded block of ice on the shore the glacial lagoon Jökulsárlón, south-east Iceland. Ice calves off Breiðamerkurjökull, an outlet glacier which flows out from Vatnajökull, the ice cap which makes up the largest ice body of Iceland. Jökulsárlón developed as Breiðamerkurjökull retreated away from the Atlantic ocean (into which it flows) and the lagoon continues to grow in size as the glacier continues to retreat (see image below).

Image Of The Week – Do My Ice Deceive Me?

Image Of The Week – Do My Ice Deceive Me?

A few weeks ago, we focussed our image of the week on very particular parts of Antarctica, which display blue ice at the surface.

Today we would like to put the spotlight on an even more extreme chromatic phenomenon : the Fyndið ísjaki Brandari (should be pronounced “/fɪːntɪð/ˈiːsjacɪ /ˈprantaːrɪ/“, even though a bit of phonetics never hurt anyone, for the sake of simplicity this phenomenon will be referred to as the FIB).

Despite our poor understanding of the FIB, this phenomenon has been recognised since ancient times. According to Icelandic folklore, FIB has been observed in remote regions at the centre of ice sheets and ice caps for many hundreds of years and was originally thought to indicate a unicorn breeding ground. However, recent studies have begun to find a more scientific explanation for this truly wonderful phenomenon.

Dr Joe Kerr, the world specialist of FIB, told us that the presented picture was an exceptional shot because colour changes, known as Layered Ice Extraordinaire (LIE), are aligned with isochronic layers, indicating a time-dependant source for the changes in colour. He even concluded that this specific FIB shows indications of originating from ice which has travelled to Iceland from tropical regions, although more thorough dating (using a new mobile software package known as TINDER) of the layering must take place to confirm this.

On the other hand, Prof Han-Ki Ding, a competitor for the title of FIB world specialist, also inspected the picture and does not agree with his colleague Joe Kerr. Han-Ki Ding, hypothesises that the thick layer of white snow on top of the coloured layers is indicative of ice of a polar origin. He even added that the snow layer that is sagging on the left part of the image provides further evidence. Recordings of a high pitched noise, know as an “ice scream“, were made when the snow collapsed into its current position. Careful analysis showed that in this particular case the collapse emitted a “coo kiedough” ice scream – indicative of ice originating at high latitudes.

Of course we could further discuss the connection between the FIB and unicorn breeding grounds but then our story would not be plausible anymore, and you might realise that today is April Fools Day… Anyway we thank you – the readers – for wasting a few minutes of your time reading this entirely uninformative post and we hope it made you smile in the process 🙂
