1. Predicting distribution and relative abundance of mid-trophic level organisms using oceanographic parameters and acoustic backscatter

   Abstract:  Data on the distribution and abundance of mid-trophic level organisms (MTLOs) in the pelagic open-ocean ecosystem are normally sparse or absent. Consequently, ecosystem models are limited in their ability to support decision-making for issues ranging from fisheries management to

2. Casal2: New Zealand’s integrated population modelling tool

   Abstract:  Casal2 (pronounced Casal-two) has replaced CASAL, New Zealand’s integrated fish stock assessment pack-age since 2002. Casal2 replicates most of CASAL’s functions such as many stocks, fisheries, and areas; age-or length-based dynamics; the use of several data sources (e.g., abundance

3. Diet overlap among top predators at the South Orkney Islands, Antarctica

   Abstract:  In order to understand interspecific trophic relationships among top predators, we analyzed diet information on nine bird and two seal species collected in the austral summer from 1996 to 2000 at South Orkney Islands. Overall, the diet of most of the predators was mainly composed of

4. Foraging patterns in the Antarctic Shag Phalacrocorax bransfieldensis at Harmony Point, Antarctica

   Abstract:  During the 1995 and 1996 summer seasons the foraging patterns of the Antarctic Shag Phalacrocorax bransfieldensis were studied by direct observation on individuals breeding at Harmony Point, Nelson Island, South Shetland Islands. During pre-laying and incubation individuals of both sexes

5. Candidate baseline data for ecosystem indicators in the Ross Sea region

   Abstract:  The research and management plan for the Ross Sea region MPA is currently under development. That plan will identify key research questions that aid in assessing the MPA’s efficacy in achieving its objectives. It may be helpful to have an agreed set of baseline data for key species which

6. Diagnostic tools for Champsocephalus gunnari stock assessments

   Abstract:  Based on a recommendation by WG-FSA in 2017 (para. 3.13), this paper presents examples for a set of standard diagnostics including R code to be used for mackerel icefish (Champsocephalus gunnari) stock assessments presented to WG-FSA. Author(s):  D. Maschette, T. Earl and R. Sinègre

7. Hierarchical monitoring plans to determine patterns of change in the Antarctic Marine Ecosystem

   Abstract:  In this paper we drawn comparison between the existing CCAMLR Ecosystem Monitoring Programme (CEMP) and plans to develop Research and Monitoring Plans for Marine Protected Areas. We recall the outcomes of the CEMP Review in 2003, and as a result highlight the intensity of monitoring

8. An experimental approach for the Antarctic krill fishery: advancing management and conservation through the use of Krill Reference Areas and Krill Fishing Areas

   Abstract:  We review reasons why the fishery for Antarctic krill is challenging to manage and consider ways in which management could be improved, whilst responsible and precautionary harvesting continues. We propose an experimental framework to help improve the scientific basis for management.

9. Developing the risk assessment framework for the Antarctic krill fishery in Area 48

   Abstract:  Recognising that CM 51-07 is scheduled to lapse at the end of the 2020/2021 fishing season, we outline a plan of work to engage with the CCAMLR community to move towards refining the krill risk assessment framework. WG-EMM has previously offered advice about how the risk assessment might

10. The vision for a Southern Ocean Observing System

    Abstract:  The Southern Ocean is fundamentally important to the Earth system, influencing global climate, biogeochemical and ecological cycles. Limited observations suggest the Southern Ocean is changing, yet chronic under-sampling makes the causes and consequences of such changes difficult to
