Brown Bluff is a basalt tuya located on the Tabarin Peninsula of northern Antarctica. This site supports a breeding colony of about 20,000 pairs of adelie penguins and about 550 pairs of gentoo penguins. Geologically speaking, Brown Bluff is simply fascinating. The towering bluffs were the result of an explosive volcanic eruption under ice. Large boulders have toppled from Brown Bluff to the beach ...[Read More]

Since my instrument was set up on an observatory south of the main station, every day I would walk past a Scott pyramid tent to go and do my research. One day, in the midst of an Antarctic storm, I caught sight of the tent deep in the drifting snow, and took this picture. Th ...[Read More]

Imaggeo on Mondays: Monitoring Antarctica’s ocean current

This week’s featured image depicts a quiet and still oceanic landscape in Antarctica, but polar scientists are studying how energetic and variable the ocean currents in this part of the world can be. In this picture, the marine research vessel RRS James Clark Ross is making its way through the Lemaire Channel, a small passage off the coast of the Antarctic Peninsula, south of the southernmost tip ...[Read More]
