1. Preliminary report on the South Sandwich Island research cruise by RRS Discovery (DY098) in January-February 2019

   Abstract:  This paper describes the structure and preliminary results of the research cruise to investigate the marine pelagic ecosystem around the South Sandwich Islands in the austral summer of 2019. The research cruise consisted of a large scale acoustic survey, following track lines established

2. Advances are urgently needed in providing regular estimates of krill stock status based on the available data

   Abstract:  CCAMLR currently manages the krill fishery in subareas 48.1 to 48.4 using an arbitrary measure (the trigger level) which was established in 1991 and is “not related to the status of the krill stock”. At the same time, CCAMLR recognises that “advances are urgently needed” specifically

3. Evidence of change to the environment, ecosystem and fishery within Area 48 indicates the need for continued precaution

   Abstract:  CCAMLR manages the krill fishery in Area 48 using a catch limit (the trigger level) which was established in 1991 based on the maximum catches reported for each subarea. Since that time the ecosystem has undergone rapid environmental change. Several studies suggest that krill numerical

4. Towards the development of Marine Important Bird and Biodiversity Areas (mIBAs) for penguins in Antarctica – an update on progress

   Abstract:  Our study area encompasses all CCAMLR MPA Planning Domains contiguous to mainland Antarctica. We present the preliminary marine Important Bird and Biodiversity Areas (mIBAS) for penguins. A total of 64 definitive sites were identified as IBAs We present a systematic overview of the

5. CEMP 2018/19 data and updated spatial analysis of Area 48

   Abstract:  This paper reports on the CCAMLR Ecosystem Monitoring Program (CEMP) data submissions for the 2018/19 monitoring season detailed by site and species, and includes an update to the Combined Standardised Index (CSI) analysis from 2018 for Area 48. The CSI analysis is a method used to

6. Weddell Sea MPA data layers have been deposited with the data publisher PANGAEA

   Abstract:  This paper informs EMM 2019 about the data layer products, which were developed for WSMPA spatial planning, and lists the DOIs to the respective PANGAEA entries. By depositing these data layers with PANGAEA, we provide transparency regarding the WSMPA development process and follow the

7. Reporting procedures for the continuous fishing method

   Abstract:  Commercial catch rates are important information for scientific evaluation of the krill resource and potential impacts of fishing on the ecosystem. Imprecise information confounds analysis and might undermine efficient and correct management actions. The following procedure now

8. Report from a krill- focused survey with RV Kronprins Haakon and land-based predator work in Antarctica during 2018/19

   Abstract:  The primary objective for this krill research activity was twofold 1) to conduct a survey that provides updated estimates of the biomass and distribution of krill which are used in models to estimate sustainable yield in CCAMLR Area 48 and 2) to develop knowledge on the marine

9. Revisiting krill ageing method using eyestalk cuticles

   Abstract:  The development of a consistent and reproducible ageing method for krill is critical for improving the precautionary management of krill fisheries. The only method to date that has shown promise in the determination of the absolute age of krill is that of Kilada et al. (2017), which

10. Habitat use of type – C killer whales (Orcinus orca) in the Ross Sea, Antarctica

    Abstract:  In Terra Nova Bay, western Ross Sea, during the austral summer 2015 ten type- C killer whales were equipped withSmart Position Only (SPOT) and depth-recording satellite transmitters (SPLASH). Hierarchical switching state-space models (hSSSM) were applied to Argos satellite tracking data
