Distribution and diversity of cumacean assemblages in Admiralty Bay, King George Island

Polish Polar Research, 2011
Distribution and diversity of cumacean assemblages in Admiralty Bay, King George IslandEleven species of cumaceans were found in 105 samples collected in Admiralty Bay (King George Island) in the summers of 1984/85 and 1985/86, from 20 to 500 m depth range. Four cumacean assemblages were distinguished using the multivariate analysis.

Soil-Landforms Interdependencies and Weathering at Admiralty Bay, King George Island, Maritime Antarctica

Quaestiones Geographicae
Soil formation in polar regions is relatively weakly recognised due to their rarity and spatial dispersion. The main pedological, sedimentological and cryogenic features of the ice-free coasts of Admiralty Bay were described and quantified with an ...

Mapping of Polar Areas Based on High-Resolution Satellite Images: The Example of the Henryk Arctowski Polish Antarctic Station

Reports on Geodesy and Geoinformatics, 2017
To produce orthophotomaps or digital elevation models, the most commonly used method is photogrammetric measurement. However, the use of aerial images is not easy in polar regions for logistical reasons.
