David and I went back to the ship for a quick lunch, and then got ourselves in the first zodiac back to shore in the afternoon. Once again, we made the difficult trek up and over big rocks with assistance from the expedition team. As with every landing, we got our onshore briefing from a staff member. Just as we were about to begin the long hike to the albatross colony, the ship's emergency siren went off. In 6 trips, I'd never heard that sound before. It meant we should abort whatever we were doing and get back to the ship. The weather had turned and conditions were becoming dangerous.
