1. Features of chronology and breeding success of Pygoscelis papua and Pygoscelis adeliae penguins in the Wilhelm Archipelago (CCAMLR Subarea 48.1)

   Abstract:  We aim to investigate the qualitative changes in the habitats of two most common species penguin populations in the Wilhelm Archipelago  Pygoscelis papua  (gentoo) and  Pygoscelis adeliae  (Adelie) penguins in the CCAMLR Subarea 48.1 under the impact of climate changes and krill fishery.

2. Coastal weather drives foraging behaviour of chinstrap penguins, Pygoscelis antarctica

   Abstract:  There is increasing interest in using higher-trophic level predators as ecosystem indicators because their performance is presumed to be linked to the overall function of the ecosystem that supports them. In the southwest Atlantic sector of the Southern Ocean, Antarctic krill (Euphausia

3. Update: Rapid unsupervised automated krill density estimation from fishing vessels (RAPID-KRILL)

   Abstract:  The RAPID-KRILL project is funded by the Antarctic Wildlife Research Fund to develop at-sea automated processing of acoustic data on fishing and research vessels. An update on the project progress is presented here, including an overview of the data processing methods. Author(s):  S.

4. Precision of growth band determination from eyestalk sections of Antarctic krill (Euphausia superba) preserved in formalin

   Abstract:  Age information for commercial fish species is crucial to fishery management. Age information for Antarctic krill (Euphausia superba) will be important for stock assessment modeling and future feedback management of krill fisheries. Samples stored in 70% ethanol provide an opportunity to

5. Consumption estimates for male Antarctic fur seals at the South Orkney Islands during the post mating migration

   Abstract:  The estimates of fur seal consumption of krill in subareas 48.1 to 48.3 which have been used in ecosystem modelling and CCAMLR’s risk assessment approach, are based on the distribution of fur seal breeding populations. Fur seal breeding colonies south of 60 o have remained relatively

6. Integrating Climate and Ecosystem Dynamics in the Southern Ocean (ICED) programme: Preliminary report of the ICED–CCAMLR Projections Workshop, 5 to 7 April 2018

   Abstract:  Climate change will alter the structure and functioning of Southern Ocean ecosystems and affect the ecosystem services they provide. The impacts of climate change will require development of conservation and management strategies that anticipate and adapt to potential changes in krill

7. Climate change impacts, vulnerabilities and adaptations: Southern Ocean marine fisheries

   Abstract:  • The Antarctic region is characterized by complex interaction of natural climate variability and anthropogenic climate change that produce high levels of variability in both physical and biological systems, including impacts on key fishery taxa such as Antarctic krill. • The impact of

8. Protocols for trawl sampling, recording of biological data, and hydrography for the 2019 International synoptic krill survey in Area 48

   Abstract:  Experience gained through participation in international programmes like BIOMASS and the CCAMLR 2000 Survey has demonstrated that standardization of equipment and methods is one of the most crucial steps for any successful work during the field sampling period and later analytical work.

9. Abundance and trends of Type B killer whales (Orcinus orca) around the western Antarctic Peninsula

   Abstract:  The western Antarctic Peninsula (WAP) is warming rapidly and we need to understand the impact of these physical changes on the marine ecosystem. The WAP is surrounded by a complex marine food web involving a number of predator and prey populations, and empirical data on abundance and

10. Second progress report of the CEMP Special Fund overwinter penguin tracking project

    Abstract:  We provide a 2 nd update on the progress of our project “Tracking the overwinter habitat use of krill-dependent predators from Subarea 48.1”. The project was initiated with support from the CEMP Special Fund in 2015/16. Of 150 tags purchased in 2016, all have been deployed and the data
