Today saw the Caledonian Star back in the South Shetland Islands on the western side of the Antarctic Peninsula. After a wildlife-packed morning ashore at Hannah Point on Livingston Island, we headed south towards Deception Island. In addition to being one of the most famous landmarks in Antarctica, Deception's perfect volcanic caldera (about 8 kilometers in diameter) is one of the best natural harbors in the world. A small part of the caldera wall has collapsed, allowing sea water to flood in. Sailing through this narrow gap into the caldera provided us with a unique and exciting navigational experience. Deception Island's last major volcanic event took place in 1970.
After a landing at Whaler's Bay 'inside' Deception, we moved further in to Pendulum Cove, where the sea water is warmed slightly by the volcanic activity underground. Here a handful of hardy souls, led gallantly by naturalist Steve MacLean, seized the opportunity to take the plunge in Antarctic waters. Shedding multiple layers of warm clothing in chilling winds over 30 knots brought forth an array of interesting squeals and screams. Enthusiastic supporters cheered on the 'Polar Plungers' from the comfort of the ship's bow.
