The weaning mass of southern elephant seal pups (Mirounga leonina) is a key predictor of their first-year survival probability. However, variations in pup morphometric characteristics (length, mass and body condition i.e. the residual of the allometric relationship between log(mass) and log(length))…
Antarctic krill (Euphausia superba) are integral to Southern Ocean pelagic ecosystems. Winters with extensive sea ice have been linked to high post-larval krill recruitment the following spring, suggesting that sea ice plays a critical role in larval overwinter survival.
A range of leaching protocols have been used to measure the soluble fraction of aerosol trace elements worldwide, and therefore these measurements may not be directly comparable.
Ice shelves affect the stability of ice sheets by supporting the mass balance of ice upstream of the grounding line. Marine ice, formed from supercooled water freezing at the base of ice shelves, contributes to mass gain and affects ice dynamics.
Glaciers and ice sheets are an integral part of Earth's system, advancing and retreating in response to changes in climate. Clues about the past, present and future behaviour of these ice masses are found throughout current and former glaciated landscapes. In this commentary…
Oxygen isotope ratios (d18O) of foraminifera in marine sediment records have fundamentally shaped our understanding of the ice ages and global climate change. Interpretation of these records has, however, been challenging because they reflect contributions from both ocean temperature and ice volume.
Plastic pollution is distributed patchily around the world’s oceans. Likewise, marine organisms that are vulnerable to plastic ingestion or entanglement have uneven distributions. Understanding where wildlife encounters plastic is crucial for targeting research and mitigation. Oceanic seabirds…
Background … Incomplete species inventories for Antarctica represent a key challenge for comprehensive ecological research and conservation in the region. Additionally, data required to understand population dynamics, rates of evolution, spatial ranges, functional traits…

Report submitted to CCAMLR: Leaper, R., Biuw, M., Favero, M, Forster, I., Johnson, C., Kelly, N., Heinemann, D., Hines, E., Landry, S., Mattila, D., Meyer, M., Parker, S., Passadore, C., Reeves, S., Soffker, M., Stimmelmayr, R., Walker, N., 2022.
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…
In response to a report of the incidental mortality of three juvenile humpback whales in the Antarctic … krill trawl fishery in Subareas 48.1 and 48.2 during the 2021 calendar year, SC-CAMLR reconvened … the Working Group on Incidental Mortality Associated with Fishing (WG-IMAF).

A total of 44 records of southern right whale mortalities and non-fatal anthropogenic interactions have been documented in Australia by … museums, wildlife agencies and researchers since 1950. Sixteen of the events involved whales that apparently survived.
First results of the Muon Spaceweather Telescope for Anisotropies at Greifswald (MuSTAnG) that is dedicated to spaceweather forecasting are reported.
Short-tailed shearwaters Puffinus tenuirostris (STSH) make use of a number of physical … oceanographic features on their foraging trips to the Southern Ocean from their breeding colonies in … southeast Australia.
