1. High-resolution ocean modelling of the South Georgia and South Orkney Islands regions

   Abstract:  The marine ecosystem associated with the ocean shelves around South Georgia and the South Orkney Islands is highly productive, with a history of commercial exploitation. Many of the key oceanographic and ecological processes that determine the structure and functioning of this ecosystem

2. Start date of the CCAMLR fishing season for Antarctic krill

   Abstract:  In this paper we consider whether the CCAMLR fishing season for Antarctic krill should start at a time of year that is based upon ecological events, rather than upon a date that is convenient for management. We review data on the breeding phenology of predators, and use data from the

3. Spatial aggregation of harvesting in Subarea 48.1, in particular during the summer and close to the coast

   Abstract:  We explore CCAMLR Catch and Effort data from the fishery for Antarctic krill for the period 1999/2000 to 2014/2015. We show that since 2013, both the number of hauls as well as the associated level of catch has increased in Subarea 48.1 during the penguin breeding season. We explore in

4. Possible options for the future management of the Antarctic krill fishery in Subarea 48.2

   Abstract:  We review the state of ecological knowledge for Subarea 48.2 and suggest that the development of any new management approach based on ecological indicators is limited by the current level of relevant ecological information. We propose that there is therefore an urgent need to improve the

5. Growth and shrinkage in Antarctic krill Euphausia superba is sex-dependent

   Abstract:  The ability of Antarctic krill Euphausia superba Dana to withstand the overwintering period is critical to their success. Laboratory evidence suggests that krill may shrink in body length during this time in response to the low availability of food. Nevertheless, verification that krill

6. Preliminary report on the South Orkneys Ecosystem Studies (SOES) field work undertaken by RRS James Clark Ross (JR15004) and associated field camps in January–February 2016

   Abstract:  This paper briefly describes the rationale and structure of the research cruise that formed a key component of the co-ordinated, multi-national South Orkney Ecosystems Studies focusing on the krill-based ecosystem in the main fishing area in Subarea 48 undertaken in the austral summer of

7. Is current management of the Antarctic krill fishery in the Atlantic sector of the Southern Ocean precautionary?

   Abstract:  This paper is a revised version of WG-EMM-15/28, which uses a question and answer format to explain the management of the Antarctic krill (Euphausia superba) fishery in the subareas 48.1 to 48.4, and current knowledge about the state of the regional krill stock. The revisions provide a

8. A first assessment of marine Important Bird and Biodiversity Areas for penguins in Subarea 48.1 (Antarctic Peninsula, and South Shetland Islands) and Subarea 48.2 (South Orkney Islands)

   Abstract:  First attempt to systematically identify marine IBAs in the Antarctic Assessed all available penguin tracking data for Subarea 48.1 (Antarctic Peninsula, and South Shetland Islands) and Subarea 48.2 (South Orkney Islands) Developed new protocols for determining candidate IBAs based on

9. Classification of Southern Ocean krill and icefish echoes using Random Forests

   Abstract:  Target identification remains a challenge for acoustic surveys of marine fauna. Antarctic krill, Euphausia superba, are typically identified through a combination of expert scrutiny of echograms and analysis of differences in mean volume backscattering strengths (S V; dB re 1 m-1)

10. Integrating Climate and Ecosystem Dynamics in the Southern Ocean (ICED) programme: developing links between ICED and CCAMLR

    Abstract:  Integrating Climate and Ecosystem Dynamics in the Southern Ocean (ICED) is a regional programme of the Integrated Marine Biogeochemistry and Ecosystem Research (IMBER) Programme and is closely linked with Scientific Committee on Antarctic Research (SCAR). ICED is undertaking integrated
