The day was spent at sea, northbound for Cape Horn from the South Shetland Islands, Antarctica. We enjoyed clear blue skies, crisp cold air, and great visibility throughout the day. Dawn broke with the most incredible light, not long after sunset (during which we were treated to a rare “green flash”). There was a stiff breeze on our tail and it was therefore a good day to be a seabird. Birds wheeled around the ship all day, making for great photography opportunities to help us hone our seabird identification skills.
