Arrowsmith Peninsula
Laubeuf Fjord is a sound in Antarctica, long in a north-south direction and averaging wide, lying between the east-central portion of Adelaide Island and the southern part of Arrowsmith Peninsula, Graham Land. It connects Hanusse Bay to the north with Marguerite Bay to the south. The southern 'border' between Laubeuf Fjord and Marguerite Bay is formed by the line between Rothera Point, Adelaide Island, and Cape Sáenz, which is the southernmost point of the Arrowsmith Peninsula. The fjord was discovered by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot, and named by him for Maxime Laubeuf, a French marine engineer who supervised building the engine for the ship "Pourquoi-Pas".
