Ammonium regeneration by Antarctic mesozooplankton: an allometric approach
Given the importance of copepods in the Southern Ocean food web, there are few assessments of their N budgets or their role in regenerating N. In this study we measured […]

Identifying patterns in the diet of mackerel icefish (Champsocephalus gunnari) at South Georgia using bootstrapped confidence intervals of a dietary index
Read more of: Identifying patterns in the diet of mackerel icefish (Champsocephalus gunnari) at South Georgia using bootstrapped confidence intervals of a dietary indexOntogenetic, inter-annual and regional variations in diet were investigated for mackerel icefish, Champsocephalus gunnari, in three successive summer seasons around South Georgia. Stomach contents from 2239 C. gunnari (130-560 mm […]

Recruitment and body size in relation to temperature in juvenile Patagonian toothfish (Dissostichus eleginoides) at South Georgia
Read more of: Recruitment and body size in relation to temperature in juvenile Patagonian toothfish (Dissostichus eleginoides) at South GeorgiaRecruitment variability in juvenile Patagonian toothfish (Dissostichus eleginoides), a commercially important, deepwater nototheniid fish, was examined at the sub-Antarctic island of South Georgia, South Atlantic. Data from 13 demersal trawl […]

Is the attempt to estimate the biomass of Antarctic fish from a multi-species survey appropriate for all targeted species’ Notothenia rossii in the Atlantic Ocean sector – revisited
Read more of: Is the attempt to estimate the biomass of Antarctic fish from a multi-species survey appropriate for all targeted species’ Notothenia rossii in the Atlantic Ocean sector – revisitedNotothenia rossii was the first target species in Southern Ocean fisheries. The species was already heavily fished at the beginning of the 1970s. The closure of the fishery for this […]

Significant intra-annual variability in krill distribution and abundance at South Georgia revealed by multiple acoustic surveys during 2000/01
Read more of: Significant intra-annual variability in krill distribution and abundance at South Georgia revealed by multiple acoustic surveys during 2000/01Three separate acoustic surveys of Antarctic krill (Euphausia superba) were conducted around South Georgia in the 2000/01 season: in October 2000 (early-season); during late December/early January 2000/01 (mid-season), and in […]

Extensive dynamic thinning on the margins of the Greenland and Antarctic ice sheets
Read more of: Extensive dynamic thinning on the margins of the Greenland and Antarctic ice sheetsMany glaciers along the margins of the Greenland and Antarctic ice sheets are accelerating and, for this reason, contribute increasingly to global sea-level rise(1-7). Globally, ice losses contribute similar to […]

Optimal estimation of changes in the mass of ice sheets
Read more of: Optimal estimation of changes in the mass of ice sheetsWe describe a new approach for estimating changes in ice sheet mass. Two methods are in common use: the ice budget and geodetic methods. The first makes use of separate […]
