Today we enjoyed another adventurous day. Early risers found killer whales off the bow of National Geographic Orion while navigating Gerlache Strait. Following breakfast our morning landing was at the Port Lockroy historic site. During the afternoon we deployed the Zodiacs to explore the scenic Lemaire Channel from water level, and amazing experience to witness the ship navigated the steep-walled fjord. We discovered sculpted icebergs and both leopard and crabeater seals sleeping peacefully on the ice.
