Ozone depletion associated with tropospheric bromine explosion in the Arctic substantially modify the oxidative capacity of the atmospheric boundary layer and promote the oxidation and deposition of gaseous elemental mercury […]
Bathymetry (ocean-bottom topography) beneath ice shelves is challenging to observe yet is vitally important for modelling how ice sheets will evolve into the future. An alternative to direct observation of […]
Accurately representing polar stratospheric clouds (PSCs) in global Chemistry-Climate Models and Earth System Models is important as they play a key role in springtime ozone depletion in polar regions by […]
Brachiopods appeared early in the Cambrian radiation and represent an important clade for understanding the origin of animal body plans and the evolution of biomineralized structures. A robust phylogenetic framework […]
We present the first multi-model study of the Antarctic sea ice response to enhanced meltwater due to dynamic mass loss from the Antarctic ice sheet. This meltwater flux (and its […]
The emperor penguin Aptenodytes forsteri is highly sea ice dependent and vulnerable to climate change, yet the at-sea distribution and habitat associations of breeding adults remain poorly understood for colonies […]
Conservation of biodiversity is a global priority as human‐driven pressures continue to intensify and alter ecosystems worldwide. Marine mammals are vulnerable species, facing numerous escalating anthropogenic threats. Here, we evaluate […]
Autonomous fixed-wing drones operating beyond visual line of sight of the pilot were used to conduct the first aerial, multi species baseline reference survey at the sub-Antarctic island of South […]
Cold regions are among the most pristine areas remaining globally, hosting unique fauna and flora. Historically, these regions have often been refugia from land-use change, resource exploitation, and pollution, but […]
Antarctic sea ice has declined since 2015, but placing this trend in a longer-term context remains challenging. Ice core methanesulfonic acid (MSA) offers a potential record of sea ice variability […]
The South Georgia continental shelf break is a highly productive and biodiverse region of the Southern Ocean, with abundant macrozooplankton forming the foundation of off- and on-shelf communities. Antarctic krill […]
The Antarctic Peninsula and Scotia Sea are experiencing the greatest pressures from climate change and fisheries in the Southern Ocean, with associated penguin population declines. However, surveys of the South […]
