Biomass of Antarctic krill (Euphausia superba) off east Antarctica (30–80°E) in January–March 2006
Abstract: A multidisciplinary, single-ship survey of CCAMLR Division 58.4.2 was conducted in January-March 2006, during which time multifrequency echosounder data were collected for the purposes of estimating the biomass (B 0) of Antarctic krill (Euphausia superba). The mean density of E. superba,

Winter distribution of chinstrap penguins from two breeding sites in the South Shetland Islands of Antarctica
Abstract: Satellite telemetry was used to determine the winter movements and distributions of eight chinstrap penguins known to breed at one of two colonies in the South Shetland Islands, Antarctic Peninsula region during the 2000 and 2004 austral winters. Six birds from a breeding site in

Technical note on the sampling procedures of the Saga Sea
Abstract: At the 2005 Scientific Committee (the Committee) Meeting (CCAMLR), Norway indicated that a Norwegian-flagged vessel, “Saga Sea” would be fishing for krill in the 2005/06 fishing season using modified gear and trawl system. The Committee agreed that this new technology would not be

Further progress on modelling the krill–predator dynamics of the Antarctic ecosystem
Abstract: This paper addresses work conducted on the Mori-Butterworth multi-species model of the Antarctic ecosystem subsequent to the Ulsan meeting of the IWC Scientific Committee. Points raised about the model during that meeting are addressed in turn. Results are quoted that suggest that krill

A comparison of model predictions from KPFM1 and KPFM2
Abstract: We compare two versions of the krill-predator-fishery model to demonstrate the extent to which the predictions of KPFM1 can be reproduced with KPFM2. We also discuss the incorporation of seasonality into parameter estimates and a necessary change in the predator recruitment function of

Comparison of long-term trends in abundance, recruitment and reproductive success of five populations of Pygoscelis penguins in the South Shetland Islands, Antarctica
Abstract: Responses of predator populations to environmental variability in the Antarctic have tended to exhibit site- and species-specific differences owing to variation in geographic settings and predator life-history strategies. Five populations of Pygoscelis penguins from King George Island

KPFM2, be careful what you ask for – you just might get it
Abstract: We have substantially revised the krill-predator-fishery model that was presented to the WG-EMM in 2005. The new version of our model is called KPFM2, and we have addressed all four of the changes which the WG-EMM indicated would be required to use the model for providing advice on the

The krill maturity cycle: a conceptual description of the seasonal cycle in Antarctic krill
Abstract: A long term study on the maturity cycle of Antarctic krill was conducted in a research aquarium. Antarctic krill were either kept individually or in a batch for 8 months under different temperature and food conditions, and the succession of female maturity stages and intermoult periods

Learning about Antarctic krill from the fishery
Abstract: Antarctic krill has been studied for many decades, but we are still long way from understanding their biology to be able to make reliable predictions about the reaction of their populations to environmental change. This is partly due to certain difficulties in relation to logistics,

Intra-annual variability in the abundance of Antarctic krill (Euphausia superba) at South Georgia, 2002–2005: within-year variation provides a new framework for interpreting previous ‘annual’ krill density estimates
Abstract: Upward-looking acoustic Doppler current profilers (300 kHz, ADCP) and echosounders (125 kHz) were deployed on moorings on- and off-shelf to the northwest of South Georgia to measure abundance of Antarctic krill continuously between 14 October 2002 and 29 December 2005. A distinct
