Paulet Island was formed by a volcano that erupted beneath an enormous sheet of ice. Now it is the site of the vast Adelie penguin colony that we visited this morning. Our lunch was delayed as we watched a large pod of killer whales near the ship. Our afternoon walks at Tay Head on Joinville Island featured a smaller Adelie penguin colony, Antarctic fur seals, and a glacier. After dinner, the ship cruised very close to huge tabular icebergs – the views were magical.
