Empirically-driven feedback management incorporating multi-scale risk assessment and an experimental framework to facilitate adaptive improvement
Abstract: Currently, several approaches to FBM have been tabled to CCAMLR – Risk Assessment (RA: Constable et al. 2016), experimental fishing (EF: WS-SM-18/05) and Decision Rule approaches (DR: Watters et al. 2016), and recently a more empirical approach using a combination of fishing fleet

Exploring trends of the krill fishery indicators among the NWAP D1MPA zones in the Subarea 48.1
Abstract: Domain 1 marine protected area (D1MPA) proposal has been developed sin 2012 and now has been intensively discussed. Its implementation will establish a new scenario for the current krill fishing fleet dynamic, therefore it is necessary to understand what represent each D1MPA zones for

Detection of predator dive patterns from stationary echosounder data
Abstract: Standard protocols for processing of echosounder data are geared towards the estimation of biomass indices of pelagic organisms. More transient visitors to the watercolumn however also give echoes, and the data provided by the echosounders may be used to assess the behaviour of these

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,

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

Ross Sea Environment and Ecosystem Voyage 2019
Abstract: New Zealand carried out a 40-day voyage to the Ross Sea from 8 January to 16 February 2019 using the research vessel Tangaroa. The purpose of this multi-disciplinary research voyage was to increase knowledge about key environmental and biological processes in the Ross Sea region of

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
