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

Remote Sensing in Ecology and Conservation
Adélie penguin (Pygoscelis adeliae) colonies can be detected from space using very high‐resolution (VHR; 0.3–0.6 m resolution) satellite imagery, as the contrast between their guano and the surrounding terrain enables colony identification even when ...

Characterization of Staphylococcus intermedius Group Isolates Associated with Animals from Antarctica and Emended Description of Staphylococcus delphini

Microorganisms, 2020
Members of the genus Staphylococcus are widespread in nature and occupy a variety of niches, however, staphylococcal colonization of animals in the Antarctic environment has not been adequately studied.

Diversity of Lecidea (Lecideaceae, Ascomycota) species revealed by molecular data and morphological characters [PDF]

, 2002
The diversity of lichens, especially crustose species, in continental Antarctica is still poorly known. To overcome difficulties with the morphology based species delimitations in these groups, we employed molecular data (nuclear ITS and mitochondrial ...

Basal reflectance and melt rates across the Ross Ice Shelf, Antarctica, from grounding line to ice shelf front

Journal of Glaciology
We present a 1000 km transect of phase-sensitive radar measurements of ice thickness, basal reflection strength, basal melting and ice-column deformation across the Ross Ice Shelf (RIS).

Lateral flexure of Erebus Ice Tongue due to ocean current forcing and fast ice coupling

Journal of Glaciology
Ice tongues are unconfined by land on their lateral margins and are sensitive to external forcing from the ocean. They are found sporadically around the Antarctic coast but are common in the western Ross Sea.

Influence of sea surface temperature in the tropics on the Antarctic sea ice under global warming

Лëд и снег, 2019
Sea ice fields in the Antarctic, in contrast to the Arctic ones, did not show a reduction in observed global warming, whereas the global climate models indicate its certain decrease.

Two new species of Antarctic gorgonians (Octocorallia: Primnoidae) with a redescription of Thouarella laxa Versluys, 1906 [PDF]

, 2009
Two new species of the genus Thouarella from Antarctic waters are described and illustrated from material collected on the Polarstern cruises ANT XVII/3 (EASIZ III), ANT XIX/5 (LAMPOS) and ANT XXI/2 (BENDEX).
