As the world’s ice diminishes in the face of climate change—from the
dramatic decline in Arctic sea ice, to thinning at the margins of both the Greenland
and Antarctic ice sheets, to retreating mo...
A few decades ago, Antarctic ice sheets were expected to grow as the
atmosphere warmed and increasing poleward moisture transport added snowfall
to regions that would remain below freezing year-ro...

The goal of the ICEFISH 2004 cruise, which was conducted on board RVIB
Nathaniel B. Palmer and traversed the transitional zones linking the South Atlantic to the Southern
Ocean, was to compare the...

The West Antarctic Peninsula (WAP) shelf is deep and detritus-based
(i.e., it is fueled by organic material sinking from intense seasonal cycles of primary
production in the water column), le...

in recent years, mass loss from the Antarctic
ice Sheet has contributed nearly 0.5 mm yr–1
to global mean sea level rise, about one-sixth of
the current rate (church et al., 2011). Around

We investigated the responses of the ecologically dominant Antarctic phytoplankton species Phaeocystis
antarctica (a prymnesiophyte) and Fragilariopsis cylindrus(a diatom) to a clustered matrix of th...
Time ravages mountains, as it does people. Sharp features soften, and bodies grow shorter and rounder. But under the right conditions, some mountains refuse to age. In a new study, scientists explain ...

Antarctic krill (Euphausia superba) were sampled in contrasting habitats: a seasonally ice-covered deep ocean
(Lazarev Sea), ice-free shelves at their northern range (South Georgia) and the Antarctic...

Despite the fact that ocean acidification is considered to be especially pronounced in the Southern Ocean, little
is known about CO2

Seabed foraging by Antarctic krill: Implications for stock assessment, bentho-pelagic coupling, and the vertical transfer of iron
Seabed foraging by Antarctic krill Implications for stock assessment bentho-pelagic coupling the vertical transfer of iron
2014/4/8
A compilation of more than 30 studies shows that adult Antarctic krill (Euphausia superba) may frequent benthic habitats year-round, in shelf as well as oceanic waters and throughout their circumpolar...
