Bigourdan Fjord is a
sound, long in an east-west direction and averaging wide, lying between
Pourquoi Pas Island and the southwest part of
Arrowsmith Peninsula, along the west coast of
Graham Land. It was discovered by the
French Antarctic Expedition, 1908–10, under
Jean-Baptiste Charcot, and named by him for
Guillaume Bigourdan, a noted French astronomer. It was roughly surveyed by the
British Graham Land Expedition, 1934–37, under
John Riddoch Rymill, and resurveyed by the
Falkland Islands Dependencies Survey, 1948–50.
