Antarctic krill (Euphausia superba) is the central prey species in the Southern Ocean food web, supporting the largest and fastest-growing fishery in the region, managed by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).
Like many polar animals, emperor penguin populations are challenging to monitor because of the species' life history and remoteness. Consequently, it has been difficult to establish its global status, a subject important to resolve as polar environments change.
The parties to the Montreal Protocol are informed by three panels of experts. One of these is the … Environmental Effects Assessment Panel (EEAP), which deals with two focal issues. The first focus is … the effects of increased UV radiation on human health, animals, plants, biogeochemistry…

U-Pb SHRIMP zircon analyses have been used to place time constraints on the Proterozoic reworking of Archaean rocks during the Rayner Structural Episode in the Oygarden Group of islands, Kemp Land, East Antarctica.
Ornithogenic soil is derived from the deposition of the fecal matter of various species of birds and is a major source of nutrient input in the Antarctic marine ecosystem. A significant proportion of microbiota of ornithogenic soil collected from an Adelie penguin colony in eastern Antarctica…
Layered orthogneisses of the Oygarden Islands preserve evidence for four high-grade deformation events (D1 to D4). Archaean D1 and D2 structures are only patchily preserved due to extensive recrystallization during D3 and D4, which represent effects of the c.1000 Ma Rayner Structural Episode (RSE).
