Marie Byrd Land is one of the most remote territories of our planet’s most inaccessible continent. It is a real privilege to just be able to contemplate its shores! Between the Ross Sea and its large shelf to the east and Bellingshausen Sea to the west, the frozen coastlines of these lands are bordered by the Amundsen Sea, partially covered by a thick ice floe. Stretching over more than a million km2 (over 620,000 square miles) in Western Antarctica, its ground is also isolated from the rest of the continent by the Transantarctic Mountains. It is certainly this geographic remoteness and its harsh climate that have made it one of our planet’s rare Terra nullius, a territory claimed by no State. In 1929, Marie Byrd Land got its name from Admiral Richard E. Byrd, in honour of his wife, following his expedition to the region. The exploration of its ice-sculpted landscapes will plunge you into the infinite Antarctic desert, where penguins, seals, whales and orcas are the only living souls. Depending on the time and weather conditions, your exploration of the region will take you towards a string of islands which, although little-known, remain fascinating: Siple Island and its eponymous mount, resulting from an old volcano and Clark Island.
