FrostByte X Fettweis: Modeling of the Greenland ice sheet surface mass balance with the regional MAR model

noreply@blogger.com (Polar Botanist) — Wed, 03 Jun 2015 07:30:00 +0000

This FrostByte was created by Xavier Fettweis, from University of Liège (Belgium), for the Constraining uncertainty in Greenland Ice Sheet surface mass balance model output and in situ validation workshop, held 19-20 May 2015, in Sheffield, UK.

This FrostByte shows that the Greenland ice sheet contribution to sea level changes is a drop over the 20th century and a rise during the 21st century.

FrostByte C Treat: Detecting permafrost aggradation in peatland ecosystems to understand the effects on climate

noreply@blogger.com (Polar Botanist) — Mon, 25 May 2015 07:30:00 +0000

This FrostByte was created by Claire Treat for the Permafrost Carbon Network Project Leads Meeting, in Flagstaff, AZ, USA, in May, 2015.

My research uses a synthesis of plant macrofossils, or small pieces of plants preserved in peat, to study the causes and effects of permafrost aggradation in boreal and arctic peatlands.

FrostByte J Strauss: Organic carbon stocks in ice-rich permafrost of the Yedoma region

noreply@blogger.com (Polar Botanist) — Wed, 20 May 2015 07:30:00 +0000

This FrostByte was created by Jens Strauss for the Permafrost Carbon Network Project Leads Meeting, held in Flagstaff, AZ, USA in May, 2015.

This FrostByte is about ice-rich Yedoma and thermokarst permafrost in the Yedoma region. I found that that this kind of permafrost stores about 213 gigatonnes organic carbon, which is a significant amount of carbon so far not included in climate models.

I Vankova: Calving and Fjord Dynamics

noreply@blogger.com (Anonymous) — Fri, 26 Dec 2014 09:00:00 +0000

Much of glacier mass is lost via calving, occasional events when glacier fronts break and fall off to the ocean. We would like to understand the conditions under which such events occur.

We have been conducting field research at Helheim glacier and adjacent Sermilik fjord. Yearly measurements of vertical salinity, temperature and pressure profiles give us a good estimate of the fjord water structure and a weather station installed at the glacier provides us with atmospheric data. Calving events cause strong perturbations in the fjord waters, which we were able to detect and separate from other signals. We will combine this with the rest of the data and with numerical models, and we hope to develop a better insight on this phenomenon.

R Hall: Drivers of North Atlantic Jet Stream Vaiability, 1870-2014

noreply@blogger.com (Anonymous) — Tue, 23 Dec 2014 09:00:00 +0000

The North Atlantic jet stream shows considerable interannual variability. Much of this is due to internal atmospehric variability. However, there are a number of potential drivers of this variability, which are capable of nudging the jet stream. The research aims to identify these drivers scross all four seasons.

E Hanna: The Jet Stream and Greenland Warming

noreply@blogger.com (Anonymous) — Mon, 22 Dec 2014 09:00:00 +0000

Rapid summer warming in Greenland since the early 1990s is much greater than global warming over the same period. This Arctic amplification may well have consequences for the behaviour of the northern hemisphere polar jet stream: a giant river of airflow in the atmosphere which is driven by thermal contrast between tropical and polar air masses.
