Coastal Antarctic ecosystems feature long periods of sea ice cover, strong seasonality in primary production, and low biodiversity relative to marginal ice zone regions. There are few records of annual cycles of biodiversity and abundance of neritic Antarctic zooplankton…
Global, regional and local sea?level projections rely on complex process?based models of the climate?ocean?cryosphere system. While extrapolation of observational data has been examined on global and regional scales, this approach has not yet been used for the additional complexities of coastal sea?
Allocation of energy is as important as energy uptake for maintaining healthy life cycles and sustainable populations of krill. Environmental factors such as temperature and food availability play important roles in the physiological performance of krill.
The Southern Ocean plays a key role in removing anthropogenic carbon dioxide (CO2) from the atmosphere, accounting for a quarter of the global ocean uptake during the Anthropocene period. Here we show, using a high-resolution ocean model under high-emission forcing (RCP8.5)…
Life at Robinson Ridge, located in the Windmill Islands region of East Antarctica, is susceptible to a changing climate. At this site, responses of the vegetation communities and moss-beds have been well researched, but corresponding information for microbial counterparts is still lacking.
Dense shelf water (DSW) overflows around Antarctica leads to the formation of antarctic bottom water, thereby driving the lower cell of global overturning circulation.
The Coupled Model Inter-comparison Project Phase 6 (CMIP6) multi-models predict future warming over Antarctica under five different scenarios, but their uncertainties remain high and have not been well constrained.
The vertically integrated zonal momentum balance of the Antarctic Circumpolar Current (ACC) is dominated by wind stress at the surface and topographic form stress (TFS) at the bottom. It has been argued that wind stress is transferred from the surface to the bottom by transient baroclinic eddies…

Marine protected areas (MPAs) are a commonly used management tool to safeguard marine life from anthropogenic impacts, yet their efficacy often remains untested.

Multiple datasets show the Antarctic Ice Sheet has lost mass over recent decades and therefore contributed to sea-level rise. Short-term variability in ice mass has been associated partly with El Niño/Southern Oscillation (ENSO), for both the grounded ice sheet and its bounding ice shelves…
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…
Physical features preserved in ice cores may provide unique records about past atmospheric variability. Linking the formation and preservation of these features and the atmospheric processes causing them is key to their interpretation as palaeoclimate proxies. We imaged ice cores from Law Dome…
We have considered TOMS (2000–2004) and OMI (2005–2021) total ozone column (TOC) data sets for the second part of winter cold period (January–March). Variations in both total ozone and characteristics of the Fourier wave harmonics with zonal numbers 1–5 are analyzed.
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.
