Andvord Bay

Location of Andvord Bay in Antarctica

Andvord Bay (64°50′S 62°39′W / 64.833°S 62.650°W / -64.833; -62.650) is a bay-like fjord, 9 nautical miles (17 km) long and 3 nautical miles (6 km) wide, which lies between Beneden Head and Duthiers Point along the west coast of Graham Land.

It was discovered by the Belgian Antarctic Expedition, 1897–99, under Adrien de Gerlache, and named by him for Rolf Andvord, Belgian consul at Christiania (Oslo) at that time.^[1]

A popular cruise-ship destination is Neko Harbour,^[2]^[3] which was discovered by Belgian explorer Adrien de Gerlache in the early 20th century. It was named for a Scottish whaling boat, the Neko, which operated in the area between 1911 and 1924.

FjordEco Project

The FjordEco Project, formally titled "Fjord Ecosystem Structure and Function on the West Antarctica Peninsula – Hotspots of Productivity and Biodiversity?(FjordEco)", is an integrated field and modeling study supported by the United States National Science Foundation. The study conducted research cruises to Andvord in Nov-Dec 2015, April 2016, and Mar-Apr 2017 to evaluate physical oceanographic processes, glacial inputs, plankton dynamics, and benthic community structure and function in Andvord Bay.^[4] Scientific publications from the project include the following:
