1. 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

2. 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

3. 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

4. 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

5. Analysis of the Chilean operation in the Antarctic krill fishery, years 2017/18

   Abstract:  This paper provides a summarized description and analysis of the activities carried out by the Chilean krill fishing ship Antarctic Endeavour throughout its first year of operation (2017-2018), which was mainly destined towards testing its fishing systems and new equipment installed for

7. Pygoscelid penguins vulnerabilities to spatio-temporal changes of the krill fisheries in the Antarctic Peninsula

   Abstract:  Fast climate changes in the Antarctic Peninsula are reducing krill density, which, by its turn, is reflected in penguin population dynamics. The increased concentration of fishing activities in this area in the last two to three decades is believed to have feedbacked the impacts of

8. Draft Research and Monitoring Plan for the South Orkney Islands Southern Shelf Marine Protected Area (MPA Planning Domain 1, Subarea 48.2)

   Abstract:  We present a revised draft Research and Monitoring Plan (RMP) for the South Orkney Islands Southern Shelf MPA, with the aim of further harmonizing CM 91-03 and CM 91-04. The draft RMP is based on the draft initially proposed in 2014 (SC-CAMLR-XXXIII/11) and revised in 2018 (SC-CAMLR

9. Acoustic and underwater survey of the Argentine Islands (West Antarctic) water area for development of network of testing sites in the summer season of 2019

   Abstract:  In the summer season of 2019 (February-April), acoustic and underwater studies of the seabed off the Argentine Islands were continued. The purpose of these studies was further development of a network of underwater testing sites in the water area of the Argentine Islands. Author(s):  A.

10. Glider-based estimates of Antarctic krill in Bransfield Strait, and the West shelf off Livingston Island, Antarctica

    Abstract:  We used long-duration, deep-diving (1000 m) hybrid gliders (Slocum G3, Teledyne Webb Research), equipped with a suite of oceanographic sensors (CTD, fluorometers, and oxygen) and a three-frequency (38 kHz, 67.5 kHz, and 125 kHz) single-beam Acoustic Zooplankton Fish Profiler (AZFP) to
