Meteoroids of sub-milligram sizes burn up high in the Earth's atmosphere and cause streaks of plasma trails detectable by meteor radars. The altitude at which these trails, or meteors…
Components such as organic carbon (Corg), carbonate, opal or barite are valuable paleoceanographic proxies, enabling the reconstruction of past changes in carbon cycling under various climate regimes, particularly when 230Th-normalization is used to reconstruct particulate vertical rain rates.
Sea ice can be interspersed vertically with both permeable and impermeable layers. These features can be smaller than a few centimetres but are important for understanding biogeochemical cycles in sea ice. Traditionally…
Satellite tagging provides vital information about the ecology of whales, not currently obtainable in any other way, but it can elicit short- and long-term impacts on individuals.
The fronts of the Antarctic Circumpolar Current (ACC) influence the growth and instability of eddies, eddy-mean flow interaction, and the development of submesoscale processes. We use in situ hydrography and directly measured velocity from a comprehensive shipboard survey of the Polar Front (PF)…
Antarctic krill (Euphausia superba) is the target of the largest commercial fishery in the Southern Ocean. Its abundance varies regionally and exhibits great interannual variability. This natural variability, combined with climate change effects…
The Sea Ice Physico-Chemistry and Ecosystems 2024 (SLOPE2024) workshop was conducted in the Saroma-ko Lagoon, Hokkaido, Japan from the middle of February to the beginning of March 2024. The aim of SLOPE2024 was to study the physical, chemical…
Understanding how marine predators explore dynamic ocean environments is key for assessing the ecological significance of different habitats and for informing conservation efforts. This is particularly critical in remote and poorly surveyed regions…
The Southern Ocean (south of 30°S) contributes significantly to global ocean carbon uptake through the solubility, physical and biological pumps. Many studies have estimated carbon export to the deep ocean, but very few have attempted a basin-scale perspective, or accounted for the sea-ice zone…
A southern right whale (Eubalaena australis) was found dead, stranded on a remote rock platform at Torndirrup, Western Australia, on 20 September 2022.
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…
Around 176500 whales were killed in the sub-Antarctic waters off South Georgia (South Atlantic) between 1904 and 1965. In recent decades, whales have once again become summer visitors, with the southern right whale (SRW) the most commonly reported species until 2011. Here…
Southern right whales (Eubalaena australis) migrate between Austral-winter calving and socialising grounds to offshore mid- to high latitude Austral-summer feeding grounds. In Australasia…
Marine protected areas (MPAs) are a commonly used management tool to safeguard marine life from anthropogenic impacts, yet their efficacy often remains untested.

We use Multi-Sensor Reanalysis and ground-based total ozone content (TOC) data to study total ozone variations in Antarctica near the dates of sudden stratospheric warmings (SSW). Three events were analyzed, including the warmings in 1988, 2002 (major warming), and 2019.
The Totten Glacier in East Antarctica, with an ice volume equivalent to >3.5?m of global sea-level rise, is grounded below sea level and, therefore, vulnerable to ocean forcing. Here…
The papers in this volume were, with a few exceptions, presented at the third Island Invasives conference, held in Dundee, Scotland in July 2017. The papers demonstrate up-scaling in several aspects of eradication operations – not least in ambition, land area, operational size…
The CHinense Exoplanet Searching Program from Antarctica is a ground-based wide-field photometric survey using the AST3 and CSTAR telescopes located at Dome A, Antarctica. Blessed with the unparalleled observing conditions on the highest point of the Antarctic plateau, three remotely controlled…

INTRODUCTION The Commission and the Scientific and Conservation Committees have adopted numerous recommendations over the years for strengthening engagement with other organisations. The IWC Secretariat, in collaboration with members of the SC and CC have been working to carry out these mandates…
A proof-of-concept study was conducted to explore the viability of automated acoustic detection of upcall vocalisations produced by southern right whales (Eubalaena australis) on their high-latitude Antarctic feeding grounds. The automated acoustic detector used was that of Shiu et al (2020)…
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'.
The response of the global water cycle to changes in global surface temperature remains an outstanding question in future climate projections and in past climate reconstructions. The stable hydrogen and oxygen isotope compositions of precipitation (?precip), meteoric water (?MW) and seawater (?SW)…
