Aerial surveys are frequently used to estimate the abundance of marine mammals, but their accuracy is dependent upon obtaining a measure of the avail?ability of animals to visual detection.
Antarctic krill (Euphausia superba) are a circumpolar species with an omnivorous diet. Knowledge of krill diet within different regions will help predict how environmental change may impact local krill populations. Krill from the Atlantic, Indian…
The Antarctic marginal ice zone (MIZ) is a highly dynamic region where sea ice interacts with ocean surface waves generated in ice-free areas of the Southern Ocean. Improved large-scale (satellite-based) estimates of MIZ extent and variability are crucial for understanding atmosphere–ice…
During 2021, and following on from 2020, net Antarctic sea ice coverage continued to exhibit strong variability (Fig. 6.11a), with distinct regional and seasonal contributions (Fig. 6.11b). The year began with below-average overall sea ice extent (SIE) in January through February (Fig. 6.11a)…
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…
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…
As we learn more about the importance of cetaceans in the Antarctic, including their populations' recovery and needs as krill and fish predators, it is increasingly clear that cetacean science is vital for informing ecosystem-based management.
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…
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…
Agenda Item(s) SC-CAMLR-41 - 10.3 - Reports of representatives at meetings of other international organisations
Agenda Item(s): WG-IMAF-2022 - 4.2.1 - Review of whale entanglement information … WG-IMAF-2022 - 4.1 - Population status of marine mammals in the CAMLR Convention Area … WG-IMAF-2022 - 4.3 - Mitigation methods for marine mammals
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)…
Antarctic krill (Euphausia superba) are amongst the most abundant animals on Earth, with a circumpolar distribution in the Southern Ocean. Genetic and genomic studies have failed to detect any population structure for the species, suggesting a single panmictic population. However…
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…
Here we present preliminary results on krill distribution from data collected from the Norwegian fishing vessel (F/V) Antarctic Endurance during her commercial operation for Antarctic krill in subareas 48.1 and 48.2 during different timings of the year in 2020, 2021 and 2022.
Evaluating the effects of climate change on Southern Ocean 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…
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…
The current krill management approach endorsed by CCAMLR will require systematic data collection on a variety of spatial and temporal scales for each of the three pillars of the plan: the biomass assessment, the Grym model, and the risk assessment layer.
At the Third Meeting of the Advisory Committee (AC3), 129 species of Procellariformes were assessed using a number of categories in order to provide Parties with an approximate priority list of species that might be considered for nomination to Annex 1 of ACAP (AC3 Doc 18).
The Advisory Committee Work Programme for the 2023 - 2025 triennium was drafted by the Advisory Committee and its Working Groups during its Twelfth Meeting (AC12), held as a virtual meeting, between 31 August and 2 September 2021.
This report has been prepared under Article IX(6)(d) of the Agreement and includes a collation of information provided under Article X(j) by Parties through the Secretariat under Article VII(1)(c) and Article VIII(10).
