New review paper on Si isotopes in Arctic and sub-Arctic glacial meltwaters

New review paper on Si isotopes in Arctic and sub-Arctic glacial meltwaters

In 2015 and 2016, we travelled around the (sub)Arctic and collected lots of samples of glacial meltwaters and subglacial sediment. We are very happy the…

New review paper on glacier algae

New review paper on glacier algae

Algae grow on melting glacier and ice sheet surfaces across the cryosphere, causing the ice to absorb more solar energy and consequently melt faster, while…

New paper on the fate of assimilated N in Antarctic glacial meltwater streams

New paper on the fate of assimilated N in Antarctic glacial meltwater streams

Microbial mats are abundant in the small glacial meltwater streams of Antarctica. Despite the limited amount of nitrogen (N) released from source glaciers and the…

New paper shows glacier size and hydrological drainage systems may influence the structure of exported microbial assemblages

New paper shows glacier size and hydrological drainage systems may influence the structure of exported microbial assemblages

Glacial meltwater streams export supra- and subglacially-derived microbial cells, along with terrestrial material from the ice-free landscape, and deliver them to downstream ecosystems. Despite the…

New paper shows Greenland ice surface albedo controlled by distributed biologically-active impurities

New paper shows Greenland ice surface albedo controlled by distributed biologically-active impurities

The Greenland Ice Sheet (GrIS) is the largest cryospheric contributor to global sea-level rise. The dominant energy source for snow and ice melt is direct…
