Hei! pim here! i am postdoc from #uio #geohyd and am catching up my original post from november. i would like to show a cool research place in #norway, the svartisen subglacial laboratory #ssl where i did my #phd. some call it "the most claustrophobic lab in the world", but it is eventually an amazing place to study what is happening under the glacier #engabreen in #northernnorway.
when we go there, we live and work under the mountain and the glacier in a tunnel network that is part of a hydro-power plant. this access gives us the opportunity to study how the glacier, the water flowing at the glacier bed and the rocks interact. this interaction is pretty complicated and we do not have enough direct observations to develop and validate physical models, hence the work we do there.
today, i want to show you a cool time-lapse video (slide the pictures) that we took after melting a cavity with hot water from the #ssl. we melt the ice to place instruments under the glacier, but we have to be fast because the ice above us create a lot of pressure and causes the glacier to deform and slide. the video shows that the ice is not a boring still material but a moving nature force #toothpaste.

Here is one of my (@andreasplach) experiments of the evolution of the #lastinterglacial #greenlandicesheet. The animation shows the ice thickness of the #icesheet. During the warm periods the ice sheet is getting smaller before it grows back towards the end of the simulation.

If you want to know more about my research check out the two articles we published recently:

Eemian Greenland SMB strongly sensitive to model choice: https://doi.org/10.5194/cp-14-1463-2018

Eemian Greenland ice sheet simulated with a higher-order model shows strong sensitivity to SMB forcing: https://doi.org/10.5194/tc-2018-225

Now that I (@andreasplach) have all these models which calculate #icesheetmelting for me, and I know how to simulate ice flow (remember: similar to water flow), I just need some temperature and
snowfall (#climatedata) to use in my models. I combine ice flow and melt models and finally can do some #icesheetmodelling. In my case, I want to know how the #greenlandicesheet looks in a period from the past which was warmer than today --- the #lastinterglacial period (approx. 125,000 years ago). I use the past conditions to get a better idea of how #greenland will look in the future #warmerclimate. My now you should not be surprised anymore, that I am using #computermodels or more precise #climatemodels to simulate the temperature and snowfall during the Last Interglacial period. #icesheets preserve snow which has fallen in the past (the snow is transformed to ice due to overburden pressure of snow which falls on top of old snow), and some of the ice on #greenland reaches back to the Last Interglacial. So it sounds like a good idea that I check out how an ice core is drilled, which I did in summer 2017 :-)! #eastgrip

I (@andreasplach) especially focus on the interaction between ice and atmosphere. Since my main interest is on a warmer-than-present climate, this basically means that I want to know how much #icemelting happens at certain temperatures. Ice melt can be measured at specific locations, but unfortunately the #greenlandicesheet is not completely covered by measuring stations. Therefore I need to use
#computermodels to simulate the melt over the whole #icesheet. There are several types of these melt models available, and a part of my research is to compare these different models to get a better idea of each of their individual strengths and weaknesses. If you are on #greenland in summer than you will see a lot of melt happening as I could experience myself at places like #russelglacier and #point660 close to #kangerlussuaq.

My research (@andreasplach) is strongly based on #computermodeling,
which means that I spend most of my time in front of the computer. However, once in a while I also get to go to the outdoors :-). At the beginning of my PhD for example I could join two amazing courses at #unisvalbard and in #karthaus, Italy, where I learned the basics of how one simulates #glaciers and #icesheets (which are basically very large glaciers) using #computermodels. I also got to experience glaciers of various sizes. I now use these basics in my research to simulate the flow of the #greenlandicesheet. The flow of an #icesheet is simulated in a similar way as the flow of water (#navierstokes), only that an icesheet flows much, much, much slower (#nonnewtonian). #icesheetmodelling #iglotakeover #portaleniglo #icesheetmelting

Hei, I'm Andreas (@andreasplach) and I'm this week's #iglotakeover for #portaleniglo. I'm a #climateresearcher and #PhD student at the Bjerknes Centre for Climate Research (#bjerknessenteret) in Bergen, Norway. I study how the #greenlandicesheet, the second largest land ice mass on Earth, behaves in a #warmerclimate using #computermodeling. In the following week I will tell you a little bit about what I do all day at the office and show you some of the amazing places I got to visit during my #phdlife. Stay tuned!

These are sediments taken from a small lake in Germany. Have a closer look and see for yourself that these deposits are made up of countless little layers. Each of these marks one season or year, so the section shown here covers thousands of years. The subtle differences in color that help us distinguish them indicate that each layer is unique. The same is true for their invisible chemical, biological and physical properties: my research focuses on measuring these to derive information about past climate change from year to year across many millennia. This long-term perspective derived from little layers of mud from the bottom of lakes create an invaluable context to help assess on-going climate change.

Before unraveling the many mysteries that polar lake sediments may hold, I want to spend some text on the exciting adventures required to bring them home from the field. This picture was taken during a recent field trip to Svalbard. The little boat drifting in front of that massive glacier was my home and means of transport for a week, moving from lake to lake. During transit, most time is spend weathering storms or getting some rest in the cramped space below deck. Things spring into action when approaching a field site: equipment, strapped on-deck, is brought on-land with zodiacs. Then the toughest part begins: dragging hundreds of kilos of equipment across the tundra to a lake of interest, while remaining vigilant against the ever-present danger of polar bears. Interested finding out more about these expeditions? Then read this piece @natgeo did on a 2017 trip up North that I was part of:
