Do I need special Antarctic clothing?

​As it can be quite cold in the Weddell Sea and Ross Sea, warm clothing is essential. Waterproof trousers and jacket against wind, rain and salt spray coming into the zodiac. Furthermore thermal underwear, fleece jackets, warm gloves and a warm hat. A down-jacket will make a stay on the ice near the penguin colony more comfortable. Rubber-boots for the landings are also needed but are provided on board.
