Resource potential and maturity estimates of Euphausia superba in East Antarctica

Frontiers in Marine Science
The East Antarctic krill fisheries are spread across two Divisions of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), Division 58.4.1 between 80-150°E and Division 58.4.2 between 30-80°E.

Ground‐truthing of satellite imagery to assess seabird colony size: A test using Adélie penguins

Remote Sensing in Ecology and Conservation, Volume 12, Issue 2, Page 305-317, April 2026.
Adélie penguin colony size can be estimated from space using very high‐resolution (VHR; 0.3–0.6 m resolution) satellite imagery due to the contrast between their guano stain and the surrounding terrain. Our study assessed the utility of VHR imagery for making indirect assessments of changes in colony size.

Environmental Variability Shapes Life‐History Trade‐Offs Within and Between Populations of a Long‐Lived Seabird

Ecology Letters, Volume 29, Issue 4, April 2026.
Life‐history theory predicts a trade‐off between allocation of resources to reproduction or self‐maintenance, yet how environmental variability shapes this trade‐off remains poorly understood. We show that black‐browed albatrosses (Thalassarche melanophris) breeding in more variable environments display slower life histories (slow, late‐onset ...

Photoacclimation of cryptophytes and diatoms to light variability in the Western Antarctic Peninsula

Journal of Phycology, Volume 62, Issue 2, Page 643-665, April 2026.
Abstract Meltwater stratification during austral summer along the rapidly warming Western Antarctic Peninsula (WAP) exposes coastal phytoplankton to sudden light shifts. Such variability is thought to modulate phytoplankton dynamics, yet the photoacclimation capacity of Antarctic phytoplankton, especially cryptophytes, remains unclear.

Quantifying the Escape Mortality of Trawl Caught Antarctic Krill (Euphausia superba).

PLoS ONE, 2016
Antarctic krill (Euphausia superba) is an abundant fishery resource, the harvest levels of which are expected to increase. However, many of the length classes of krill can escape through commonly used commercial trawl mesh sizes. A vital component of the

Patterns of total mercury and methylmercury bioaccumulation in Antarctic krill (Euphausia superba) along the West Antarctic Peninsula.

Science of the Total Environment, 2019
We examined mercury (Hg) accumulation in juvenile and adult subpopulations of Antarctic krill (Euphausia superba) collected west of the Antarctic Peninsula.

Studies on the Lipid of Euphausiacea, Euphausia superba. II

Journal of Japan Oil Chemists' Society, 1964
Properties of the phospholipids contained in Euphausia superba separated from stomach of fin whale in the Antarctic Ocean were studied from the view point of utilization of macro-plankton.Mixed fatty acids prepared from the phospholipids were identified with paper chromatography, as their 2, 4-dinitrophenylhydrazones for the saturated acids, and as ...

Evidence for a decline in the population density of Antarctic krill Euphausia superba Dana, 1850 still stands. A comment on Cox et al

Journal of Crustacean Biology, 2019
Antarctic krill ( Euphausia superba Dana, 1850) exemplifies the key role of marine crustaceans in fisheries, foodwebs, and biogeochemical cycles. Ecological understanding and policy decisions require information on population trends.

Spatial variability in total and organic mercury levels in Antarctic krill Euphausia superba across the Scotia Sea.

Environmental Pollution, 2019
Total and organic mercury concentrations were determined for males, females and juveniles of Euphausia superba collected at three discrete locations in the Scotia Sea (South Orkney Islands, South Georgia and Antarctic Polar Front) to assess spatial ...
