Review of some assumptions for modelling Patagonian toothfish dynamics at CCAMLR Subarea 48.3
Abstract: During the year 2005 meeting of the WG-FSA two different methods for assessing ... Patagonian toothfish stock in CCAMLR Subarea 48.3 were available to the Working Group: CASAL and ASPM (WG-FSA ... -05/16; WG-FSA-05/73). Although the underlying basic age-structure population dynamics models in both ... cases were similar, there were considerable differences in assumptions and implementations of the two ...

Antarctic sea ice losses drive gains in benthic carbon drawdown
Abstract: Loss of sea-ice, ice shelves and retreat of coastal glaciers around the Antarctic ... Peninsula in the last few years has exposed new open water, allowing large blooms of phytoplankton to ... flourish in the newly exposed coastal areas. This new productivity has important consequences as the ... phytoplankton die and sink to the sea-bed where the carbon is sequestered for thousands of years. This carbon ...

Model-based, ecosystem risk assessments of MPA scenarios in Planning Domain 1
Abstract: The Scientific Committee has previously considered results from the Krill-Predator ... -Fishery Model to assess the risks of distributing catch limits for krill among small-scale management ... units (SSMUs) in Subareas 48.1, 48.2, and 48.3. Here we describe a method to update the ... parameterizations of this model and conduct comparable risk assessments at smaller spatial scales. We use the method ...

A study of UK and Russian surveys using acoustics to augment trawling methods in shelf waters off South Georgia (Subarea 48.3)
. Both used acoustic and trawl methods, and this paper uses both datasets to explore the similarities and ... differences between the surveys and discuss how much of the variation between the vessels was due to ... differences in the gear used and how much was due to natural spatial/temporal variability of the stock. The ... acoustic surveys indicated that icefish were not only located near to the seabed, but that a significant ...

Proposal for an experimental crab fishery in Subarea 48.3
Abstract: An experimental management strategy is proposed for the Paralomis spinosissima fishery ... around South Georgia. The strategy is designed to answer specific, a priori questions about the ... years/fishing seasons. Phase 1 occurs at the start of the first fishing season and is a "survey ... fishing operations continue until the TAC for the first fishing season is attained. Phase 2 starts at the ...

Krill aggregation characteristics: spatial distribution patterns from hydroacoustic observations. Polar Biology (in press)
Abstract: The distributional features and physical characteristics of some 1500 krill (Euphausia ... superba Dana) aggregations detected and sized acoustically in the south-west Indian Ocean are described ... . The aggregations were on average considerably smaller than elsewhere in the Antarctic. Aggregation ... biomass was log-normally distributed with a mean of 0.18 t. Only 3% of the aggregations were heavier than ...
