Antarctic krill (Euphausia superba) are integral to Southern Ocean pelagic ecosystems. Winters with extensive sea ice have been linked to high post-larval krill recruitment the following spring, suggesting that sea ice plays a critical role in larval overwinter survival.
Understanding how sea ice serves zooplankton species during the food-limited season is crucial information to evaluate the potential responses of pelagic food webs to changes in sea-ice conditions in the Southern Ocean. Stable isotope analyses (13C/12C and 15N/14N)…
Polynyas are persistent and recurrent regions of open water and/or thin ice or reduced ice concentration, tens to tens of thousands of square kilometers in areal extent…
This paper aims to provide the overview needed to include krill in food-web models and to guide modellers to key sources of data. It describes the strengths of each method of sampling krill, i.e. with nets (for historical time series, demographic information and live krill), acoustics (distribution…
Abstract We examined the incidence of extreme … diving in a 3-year overwintering study of emperor … penguins Aptenodytes forsteri in East Antarctica. We … defined extreme dives as very deep (> 400 m) and/or … very long (> 12 min).
The effect of different light regimes on physiological parameters (feeding activity, oxygen consumption, and … activity of the metabolic enzyme malate dehydrogenase [MDH]) of Antarctic krill, Euphausia superba, was studied … over 12 weeks under laboratory conditions.
Antarctic coastal krill (Euphausia crystallorophias) were collected in Austral winter (July/August) 1999 in the Mertz … Glacier polynya off the coast of East Antarctica and were compared to krill collected off East Antarctica during … summer in 1996 and 2001 and spring 1999.
The first three cruises in the 'year round' Southern Ocean GLOBEC series for 2001-2002 were conducted from March - June 2001. International Whaling Commission researchers participated in all three cruises (Gould LMG 01-03 USA mooring cruise…
