Adult specimens, additional juvenile specimens, egg cases and embryos were used to provide a more detailed anatomical description of the Kerguelen sandpaper skate Bathyraja irrasa…
Introduction: This document updates the research bibliography of SC/66b/SAN01 presented in 2016. The Southern Ocean Sanctuary (SOS) was established by the Commission in 1994. The area covered by the SOS in combination with the complementary Indian Ocean Sanctuary (IOS) is shown in Figure 1.
Despite widespread iron (Fe) limitation in the Southern Ocean, intense phytoplankton blooms are observed around productive coastal regions such as the Mertz Polynya (off George V Land and Adelie Land, East Antarctica; 140–155°E). Sources of Fe across coastal East Antarctica vary…
To understand the scope and scale of the loss of biodiversity, tools are required that can be applied in a standardized manner to all species globally, spanning realms from land to the open ocean.
Echosounder data are widely collected and employed to address multitude scientific questions, from characterizing pelagic marine ecosystems, to investigating the behaviour and dynamics of marine organisms, and estimating the abundance and biomass of marine resources.
Contracting governments to the International Convention for the Regulation of Whaling are required to provide an annual National Progress Report summarising cetacean related activities annually.
Following open, competitive Calls for Proposals in 2016/17, 2018/19 and 2019/20 a total of £144,058 GBP, £489,154 GBP and £129,955 GBP, respectively, were allocated from the IWC-Southern Ocean Research Partnership (IWC-SORP) Research Fund to 31 research projects in total. In addition…
Among large cetaceans in the Southern Hemisphere, fin whales were the most heavily exploited in terms of numbers taken during the period of intense industrial whaling. Recent studies suggest that…
Blue whale populations each produce distinctive repeated songs that are stable over periods of decades, and can be used to identify where each population resides and moves. In the Southern Hemisphere and northern Indian Ocean, there are at least seven distinct populations based on their songs…
Evaluating the effects of climate change on Antarctic marine living resources is a priority topic for CCAMLR and was identified by the 2022 Scientific Committee Symposium as a key area of research. Acknowledging the need to better coordinate, target and integrate scientific advice on climate change…
Antarctic krill are a fundamental component of Southern Ocean ecosystems and perturbations to krill populations have ramifications for the entire ecosystem. Krill are fished across the Southern Ocean and sustainable management of this fishery is a high priority for the Australian Government.
Since 2019 there has been considerable discussion by the Scientific Committee and its Working Groups regarding data collection issues in the krill fishery. This document outlines issues that have been identified for consideration by the Scientific Committee and its working groups…

Introduction … Miller and Kelly (2023) provides some guidelines on spatial model-based estimation of abundance (and its uncertainty) from counts of cetaceans obtained using standard distance sampling line transect surveys.
The SCAR Krill Expert Group (SKEG) aims to improve the understanding of krill biology and ecology and serve as a link between the scientific krill community and the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), which manages the Antarctic krill fishery.
The scope of this document is model-based estimation of abundance (and its uncertainty) from counts of cetaceans obtained using standard distance sampling line transect surveys (e.g., Buckland et al., 2015).
Background … Satellite tags were deployed on 50 east Australian humpback whales (breeding stock E1) between 2008 and 2010 on their southward migration, northward migration and feeding grounds in order to identify and describe migratory pathways, feeding grounds and possible calving areas.
As the use of coastal and offshore environments expands, there is a need to better understand the exposure of marine megafauna to anthropogenic activities that potentially threaten their populations. Individual satellite telemetry studies are often hampered by small sample sizes…
Individual life-history traits, such as age and sex, influence vital rates in most large vertebrate species. Developmental differences are especially profound in polygamous mating systems. One of the most polygamous of all mammals, the southern elephant seal (Mirounga leonina)…
Following the request by WG-SAM-2021 (SC-CAMLR 2021a, para. 10.3) and the presentation of the preliminary krill stock assessment in Maschette et al. (2021a; 2021b) to WG-FSA-2021 (SC-CAMLR 2021b, paras. 5.8 - 5.13)…
Estimates of the distribution and density of Antarctic krill (Euphausia superba Dana, 1850) were derived from a large-scale survey conducted during the austral summer in the Southwest Atlantic sector of the Southern Ocean and across the Scotia Sea in 2018–19, the '2018–19 Area 48 Survey'.
An international workshop to investigate a potential use of ageing method for the Antarctic krill (Euphausia superba, Dana) based on growth band counts observed in krill eyestalks was held in August and November 2021.
The annual meeting of the SCAR Krill Action Group (SKAG) was held online from 7 to 11 March 2022 at 1500-1700 UTC as a series of Zoom meetings, and attended by around 60 participants each day. The meeting consisted of SKAG administrative updates…
