Humpback Whales (Megaptera novaeangliae) feeding on Krill in Wilhelmena Bay, Antarctic Peninsular and surfacing wth a metre of a zodiak. The whales migrate here in the summer to feed on the Krill. Krill numbers have declined by over 50%. They feed on algae that grows on the underside of sea ice, As the sea ice melts, both algae and krill decline. This shot has penguins resting on an iceberg in the background.

A birdwatcher is on the lookout for a particular penguin, which left for sea about a week ago. He needs to catch it just as it returns to land, before it enters the colony to feed its chick. This is to recover the GPS tag glued to its plumage, which has measured a large number of parameters (dive depth, immersion time, water temperature and salinity, and above all GPS position).
