After a busy week exploring the Antarctic Peninsula, we spent a relaxing day at sea, heading north to Ushuaia. Our crossing of the Drake Passage earlier in the trip was incredibly calm and, although most of today had been pretty calm, the ship did start rocking more by about 15:00 and continued to pick up throughout the afternoon.

By the evening there was definitely enough motion to cause some of us have issues sleeping, with swells up to 18 feet. We had a good number of albatrosses and cape petrels circling the ship in the afternoon, keeping the birders amongst us occupied.

There were three talks today. One by Peter, the undersea specialist onboard who talked about his time working on an Antarctic station. After lunch, Marylou spoke about the oft overlooked Antarctic keystone species – krill. Max then talked about working on assignment with National Geographic.
