Improved parametrization of Antarctic krill target strength models [PDF]

The Journal of the Acoustical Society of America, 2006
There are historical discrepancies between empirical observations of Antarctic krill target strength and predictions using theoretical scattering models. These differences are addressed through improved understanding of key model parameters. The scattering process was modeled using the distorted-wave Born approximation, representing the shape of the ...

The importance of Antarctic krill in biogeochemical cycles [PDF]

Nature Communications, 2019
AbstractAntarctic krill (Euphausia superba) are swarming, oceanic crustaceans, up to two inches long, and best known as prey for whales and penguins – but they have another important role. With their large size, high biomass and daily vertical migrations they transport and transform essential nutrients, stimulate primary productivity and influence the ...

Non‐Starch Purple Sweet Potato Polysaccharide Ameliorates Lipopolysaccharides‐Induced Acute Colitis by Regulating Gut Function and Inactivating the NOD‐Like Receptor Protein 3 Signaling Pathway

Food Frontiers, Volume 7, Issue 2, March 2026.
Purple sweet potato polysaccharide (PSP) ameliorates lipopolysaccharide‐induced ulcerative colitis in mice through multiple coordinated mechanisms. Oral PSP administration dose‐dependently: (1) Modulates gut microbiota composition and increases short‐chain fatty acid levels; (2) strengthens intestinal barrier function; (3) attenuates systemic ...

The potential role of Antarctic krill faecal pellets in efficient carbon export at the marginal ice zone of the South Orkney Islands in spring [PDF]

, 2017
Antarctic krill (Euphausia superba) play a central role in the food web of the Southern Ocean, forming a link between primary production and large predators.

Projected Warming of the Southern Ocean Disrupts Embryonic Development and Hatch Timing in Antarctic Fish

Global Change Biology Communications, Volume 1, Issue 1, March 2026.
Embryos are particularly sensitive to thermal challenge. Antarctic fish embryos raised at projected Southern Ocean temperatures hatch during the winter, have a high incidence of morphological abnormalities, have shorter body lengths, and express genes indicative of cellular stress.

Restricted regions of enhanced growth of Antarctic krill in the circumpolar Southern Ocean [PDF]

, 2017
Food webs in high-latitude oceans are dominated by relatively few species. Future ocean and sea-ice changes affecting the distribution of such species will impact the structure and functioning of whole ecosystems. Antarctic krill (Euphausia superba) is a

Factors impacting the timing of reproductive development in female Antarctic krill at the northwestern Antarctic Peninsula

Frontiers in Marine Science
The northwestern Antarctic Peninsula is an important spawning, recruitment, and overwintering ground for Antarctic krill. The region is warming rapidly, and the current impacts of climate and environmental variability on the reproductive cycle of krill ...

Advection, krill, and Antarctic marine ecosystems

Antarctic Science, 2004
Advective processes are recognized as being important in structuring and maintaining marine ecosystems. In the Southern Ocean advective effects are perhaps most clearly observed because the Antarctic Circumpolar Current (ACC) provides a connection between most parts of the system, including open ocean and continental shelf regions.

Spatial Resolution Impact Assessment for Long‐Term Population Monitoring of Adélie Penguin Guano

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Adélie penguins (Pygoscelis adeliae) are key indicators of the Antarctic ecosystem, and remotely sensed guano stains offer an efficient means of estimating breeding abundance. Landsat medium‐resolution (MR) imagery enables long‐term monitoring through its archive.
