We are investigating how dark particles (black) and microbial processes (Bloom) drive the melt of the Greenland Ice Sheet.
We recently published a paper in The Cryosphere which examines the dynamics of dark ice in south-west Greenland. Some of the largest declines in the albedo of the ice sheet … Continue Reading Summary: Dark ice dynamics of the south-west Greenland Ice Sheet
Our new paper in The Cryosphere presents a model for predicting the spectral albedo reduction resulting from biological growth on snow or ice. The biomass concentration and pigmentation of cells, … Continue Reading TCD Paper: Bioalbedo model and critique of empirical methods
In the 4 months since our return from Greenland, the Black and Bloom team has been busy analysing samples, collecting data, and preparing manuscripts. In August, Steffi, Alex Holland, Liane, … Continue Reading Particulate geochemistry update: Using synchrotron light to see black carbon nanoparticles
The hard grind of processing and analysing our field samples is well underway, some two months after the field season ended. Most of us would die for even the 1% … Continue Reading Perspiration after fieldwork
Joe Cook has had a paper accepted in Cryosphere too. The link and abstract follow. https://www.the-cryosphere-discuss.net/tc-2017-73/ The darkening effects of biological impurities on ice and snow have been recognized as … Continue Reading Quantifying bioalbedo: A new physically-based model and critique of empirical methods for characterizing biological influence on ice and snow albedo
Andrew Tedstone has just had a paper accepted in The Cryosphere. The link and abstract for the paper are given below. https://www.the-cryosphere-discuss.net/tc-2017-79/ Runoff from the Greenland Ice Sheet (GrIS) has increased … Continue Reading Dark ice dynamics of the south-west Greenland Ice Sheet
Black and Bloom’s second field team to hit the ice this year were proud to host the Science Editor of the BBC, David Shukman, and his team, for a night … Continue Reading Black and Bloom hits the press
A mix of white snow, darkening bare ice and blue melt streams near the snow line on the Greenland Ice Sheet last summer, in the vicinity of our camp. The … Continue Reading First team return to Kanger tomorrow morning
I just chatted to the field team. They remain in very good spirit. The melt has been very limited by cloud and low temperatures over the last week, and there … Continue Reading Melting restarts in earnest
New to the ice By Andy Connelly I am writing this on the way home after a successful eighteen days working on the Greenland ice sheet. As a lab manager … Continue Reading Lab Manager Andy Connelly was new to the ice. Here’s his blog.
We have just had a partial crew change, with Andy and Jim returning to Leeds and Alex A(nesio), Liane and Laura coming into camp. The transition has been pretty smooth, and … Continue Reading Ewa’s blog of the first 16 days…….
News from the team is that the melt is proceeding quickly now, but that they are dealing with the slush relatively easily. We are fortunate that the snow depth in … Continue Reading Field Team managing the slush comfortably so far
Chris called from camp this morning and reports that the melt is on. Bizarrely, the surface around the camp seems to have gone up by about 5 cm, presumably because … Continue Reading The melt is on……
A text from the field team’s satellite phone says that the snow is starting to melt slowly. The snowmelt chemist in me is very excited now, because melting and freezing cycles … Continue Reading Snow is melting slowly
All is well at the snow camp, morale is high and the team are still busy sampling snow. Last night was cloudy, and they were on high alert for a … Continue Reading Waiting on a sunny day…..
Jim and Andy have the met station up and running, and air temperatures are down to -6 C at night and above freezing during the day. Alex, Chris and Jenine have been … Continue Reading Snowpack ready to melt
