An adult skua sits on its nest near a nest marker. These markers made it easier for scientists to find skua nests, which blend into their surroundings and are often difficult to find.

A skua steals an egg from an Adelie penguin nest as nearby Adelie penguins look on in defense of their own nests. Skua predation is a major cause of mortality in penguin eggs and chicks.

Antarctic krill, Euphausia superba. The small front appendages are used for raking tiny bits of algae from ice. The green mass in the photo is the hepatopancreas, and bioluminescent (light-emitting) organs are visible at the base of the eyestalk and thorax.

Arctowski station seen from the high hillside above the base. Near lighthouse are the aquarium building and Biological Lab, next the meteorological building. Yellow building is main living quarters, behind that a big freezer and at angle, greenhouse. 2 large buildings in foreground are garages and storage areas. Silver bldg is generator bldg and yellow bldg to right is old radio bldg.

These are the Aquarium (smaller) and Biological Lab bldgs on the point. The picture is taken from the beach looking Northwards. The bulk of the Arctowski Polish Station is to the left of picture.
