Seasonal Distribution of the Fin Whale (Balaenoptera physalus) in Antarctic and Australian Waters Based on Passive Acoustics Frontiers in Marine Science, 2022 (Ref: 16470)
Category 1: Peer-reviewed literature

The fin whale is listed as globally vulnerable, with ongoing threats to their population, yet little is known about the distribution and movements of the Southern Hemisphere sub-species, Balaenoptera physalus quoyi.

Diel patterns of fin whale 20 Hz acoustic presence in Eastern Antarctic waters Royal Society Open Science, 2023 (Ref: 16779)
Category 1: Peer-reviewed literature

This study presents evidence of diel patterns in fin whale (Balaenoptera physalus) 20 Hz acoustic presence in Eastern Antarctic waters. Passive acoustic recordings were collected at four sites in Eastern Antarctica from 2013 to 2019.

New Zealand southern right whale (Eubalaena australis; Tohora no Aotearoa) behavioural phenology, demographic composition, and habitat use in Port Ross, Auckland Islands over three decades: 1998–2021 Polar Biology, 2022 (Ref: 16690)
Category 1: Peer-reviewed literature

Changes in habitat availability and prey abundance are predicted to adversely influence survival and reproduction of wildlife in the Southern Ocean. Some populations of southern right whale (SRW; Eubalaena australis) are showing dramatic changes in habitat use.

A dynamic framework for assessing and managing risks to ecosystems from fisheries: demonstration for conserving the krill-based food web in Antarctica Frontiers in Ecology and Evolution, 2023 (Ref: 16864)
Category 1: Peer-reviewed literature

The ecosystem approach to fisheries has been discussed since the 1980s. It aims to reduce risks from fisheries to whole, or components of, ecosystems, not just to target species. Precautionary approaches further aim to keep the risk of damage to a low level. Here…

Scientific echosounder data provide a predator's view of Antarctic krill (Euphausia superba) Scientific Data, 2023 (Ref: 16853)
Category 1: Peer-reviewed literature

Raw acoustic data were collected in East Antarctica from the RSV Aurora Australis during two surveys: the Krill Availability, Community Trophodynamics and AMISOR Surveys (KACTAS) and the Krill Acoustics and Oceanography Survey (KAOS) in the East Antarctic (centre coordinate 66.5° S, 63° E).

Assessing the viability of estimating baleen whale abundance from tourist vessels Frontiers in Marine Science, 2023 (Ref: 16762)
Category 1: Peer-reviewed literature

Many populations of southern hemisphere baleen whales are recovering and are again becoming dominant consumers in the Southern Ocean. Key to understanding the present and future role of baleen whales in Southern Ocean ecosystems is determining their abundance on foraging grounds.

Pelagic forage fish distribution in a dynamic shelf ecosystem–Thermal demands and zooplankton prey distribution Estuarine, Coastal and Shelf Science, 2021 (Ref: 16717)
Category 1: Peer-reviewed literature

The fine-scale distribution of pelagic forage fish is shaped by competing factors as fish optimise foraging while avoiding predation.

Antarctic krill and its fishery: current status and challenges Antarctic Environments Portal, 2022 (Ref: 16649)
Category 1: Peer-reviewed literature

The Antarctic krill is a dominant species of the Southern Ocean ecosystem, with possibly the largest biomass of any wild animal species on Earth. Krill play fundamental roles in marine food webs, including carbon cycling, and nutrient cycles.

Standing stock of Antarctic krill (Euphausia superba Dana, 1850) (Euphausiacea) in the Southwest Atlantic sector of the Southern Ocean, 2018–19 Journal of Crustacean Biology, 2021 (Ref: 16595)
Category 1: Peer-reviewed literature

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’.
