Moss carpets are a common feature in the maritime Antarctic. They provide habitats for a diverse community of organisms, including microbial groups, micro-invertebrates, and micro-arthropods, all of which depend on […]
Since the 1970s, Pine Island Glacier has exhibited thinning, acceleration, and retreat. During the last decade, the ice shelf has undergone major geometric changes, whilst the quantity and temperature of […]
The Eocene–Oligocene transition (EOT), approximately 34 million years ago, represents one of the most profound climate shifts in Earth’s history—a rapid cooling that marked the transition from the warm Eocene […]
Fish are among the most understudied components of the Southern Ocean food web, yet they are critically important to the functioning of Antarctic marine ecosystems (Caccavo et al., 2021; McCormack […]
Interactions between whistler‐mode chorus waves and electrons are a key driver of dynamics in Earth’s radiation belts. These global dynamics are often described using Fokker‐Planck diffusion models.Whilst, in many cases, […]
Recent ground-based radio-echo sounding (RES) surveys conducted by Centro de Estudios Cientificos (CECs) across the Ellsworth Subglacial Highlands (ESH), a topographically complex region near the Amundsen–Weddell ice divide (AWID), reveal […]
Connecting the West Antarctic Ice Sheet to the southern Antarctic Peninsula, northern Ellsworth Land is a region of enigmatic glacial history now experiencing significant cryospheric change. Large portions of the […]
The discovery of long-term accumulations of snow petrel stomach-oil deposits in Antarctica have provided an excellent opportunity to reconstruct changes in climate, ice-sheet thickness and sea ice. However, providing age […]
Very high-resolution (VHR) satellite imagery can increase the temporal frequency and spatial scale of wildlife studies and complement conventional monitoring methods, to address data gaps globally. However, most gaps in […]
Background Antarctic marine food webs are expected to be significantly impacted by future climate change. In particular, the recent rapid regional warming in the West Antarctic Peninsula has, and will […]
Background: Alongside their direct perceptions of prey, Northern gannets (Morus bassanus) likely derive foraging cues from memory of previously successful foraging areas (private information), and from conspecifics (public information). Together […]
The collapse of Northern Hemisphere ice sheets has been deemed as a trigger of positive climate feedback during Quaternary glacial terminations. Increasing boreal summer insolation is widely considered the primary […]
