Annual migrations of pelagic fish stocks into a krill hotspot
Abstract: We report here on the existence of seasonal fish migrations into a krill hotspot, utilized both by central place foragers and the industry. We do not have trawl samples overlapping with the acoustic data, but the behaviour displayed suggests that the fish are planktivorous. Furthermore,

Using stationary acoustic platforms to assess precision and accuracy of acoustical krill surveys
Abstract: The current CCAMLR protocol specifies daytime acoustic sampling in order to avoid issues of krill migrating too close to the surface to be acoustically detected, as well as potential issues of diel changes in acoustic scattering strengths. However, due to logistic constraints, acoustic

Preliminary results on the observations of cetaceans in the CCAMLR Statistical Subareas 48.1 and 48.2
Abstract: Visual observations of cetaceans were conducted aboard the Ukrainian krill fishing vessel More Sodruzhestva. Observations were made during December 2018 – to January 2019 in Subareas 48.1 and 48.2. 66 baleen whale registrations were recorded. Whale’s behavior was observed and analyzed.

Adélie penguins’ response to unmanned aerial vehicle at Cape Hallett in the Ross Sea region, Antarctica
Abstract: Aerial photography is widely accepted as a useful method for monitoring penguins in Antarctica, but there are concerns about the disturbance it causes to penguins in the process. Since 2016, aerial photography using unmanned aerial vehicles (UAVs) has been carried out by Korean

Stable isotope analysis reveals trophic variation in adult Antarctic krill (Euphausia superba) around the Antarctic Peninsula from austral fall to early winter
Abstract: The Antarctic krill (Euphausia superba) is a key species in the Southern Ocean ecosystem and an important link in the food web of the Antarctic ecosystem. The trophic information for this species during the transition from the austral fall to the winter is important to understand its

Engaging ‘the crowd’ in citizen science and remote sensing to learn about habitat affinity of two Southern Ocean seals
Abstract: Satellites Over Seals (SOS) is a crowd-sourced, remote sensing approach to identify presence/absence patterns of the Weddell seal (Leptonychotes weddellii), and has recently been adapted for crabeater seals (Lobodon carcinophagus) in the Weddell Sea region. Satellites Over Seals provides

How trophic dynamics of adult Antarctic krill Euphausia superba responses to the condition of no ice in the water during the winter: a case study at South Georgia?
Abstract: Understanding the variation in krill diet during winter is crucial to elucidate the overwintering of krill in the Southern Ocean. The information on trophic variation of krill under ice-free waters during the winter can also provide the insight for understanding the response of krill to

Change in environmental conditions of the Southern Ocean observed by satellites and data-assimilating models between 1981 and 2019
Abstract: We provide a summary of environmental change in the Southern Ocean over the period of satellite observaton (1981 to present). The environmental data we consider are: (1) chlorophyll-a concentration from merged observation of SeaWiFS and MODIS-Aqua (1987–2019); (2) sea-surface temperature
