Acquiring a ‘base datum of normality’ for a marine ecosystem: the Ross Sea, Antarctica
Abstract: The Ross Sea Shelf Ecosystem (RSShelfE) offers the last chance to understand ecological processes in a system where both top-down and bottom-up forcing are still intact. Elsewhere in Earth’s oceans the systems used for understanding ecological processes and fishery effects all have

Foraging patterns in the Antarctic shag (Phalacrocorax bransfieldensis) at Harmony Point, Antarctica
Abstract: During the 1995/96 and 1996/97 summer seasons the foraging pattern of the Antarctic Shag Phalacrocorax bransfieldensis was studied by direct observation on individuals breeding at Harmony Point, Nelson Island, South Shetland Islands. During pre-laying and incubation individuals of both

Demography of Antarctic krill in the Lazarev Sea (Subarea 48.6) and the Elephant Island area (Subarea 48.1) in 2004
Abstract: Standardized krill net sampling surveys were conducted in the Lazarev Sea (Subarea 48.6) in April 2004 and in the Elephant Island area (Subarea 48.1) in January and February/March 2004. Krill densities in the Elephant Island area were below the long-term average which mark a substantial

A possible framework in which to consider plausible models of the Antarctic marine ecosystem for evaluating krill management procedures
Abstract: CCAMLR requires an assessment method for recommending a subdivision of the krill catch limit in Area 48 that will be highly likely to achieve the objectives of the convention despite the uncertainties in knowledge. This will be part of the management procedure governing the krill fishery

Incidental seal entanglements on trawl vessels fishing for krill in CCAMLR Subarea 48.3
Abstract: Observers on krill vessels fishing around South Georgia in the 2003 fishing season recorded fur seal captures by some krill fishing vessels. These captures can be attributed to the absence of effective mitigation measures (escape panels in the nets) and lack of experience of crews new to

The applicability of international conservation instruments to the establishment of marine protected areas in Antarctica
Abstract: Many international conservation treaties, non-binding agreements and other instruments that have relevance to marine protected area (MPA) development provide for action to be taken globally, and thus include Antarctica within the scope of a worldwide system of marine protected areas.

Food consumption estimates of southern elephant seal females during their post-breeding aquatic phase at South Shetland Islands
Abstract: Labelled water methodology was used to quantify energy expenditure during lactation and energy gain during the post-breeding aquatic phase in Southern elephant seal females at Stranger Point, King George Island (25 de Mayo). During lactation females spent a mean of 6021±1365 Mj, which

Physical forcing in the southwest Atlantic: ecosystem control
Abstract: In the southwest Atlantic sector of the Southern Ocean, temporal variability in the physical environment has been recorded since the early part of the last century. For example, ocean temperatures are known to vary both between seasons and between years. Time series analysis of sea
