Andvord Bay is a bay on the south-western side of the Arctowski Peninsula, on the Danco Coast along the west side of Graham Land in the British Antarctic Territory. The bay is 9 nautical miles long and 3 nautical miles wide, lying between Beneden Head and Duthiers Point.

The bay was roughly charted by the Belgian Antarctic Expedition between 4th and 6th February 1898, and named Baie Andvord or Baie d'Andvord after Rolf Andvord, Belgian Consul in Christiania at that time. The bay was photographed from the air by the Falkland Islands and Dependencies Aerial Survey Expedition in the 1956-57 season.

Geography

Andvord Bay extends in a north-west direction from Forbidden Plateau. The Laussedat Heights on the Arctowski Peninsula and Rongé Island are to the east of the bay, which opens onto the Gerlache Strait opposite Anvers Island and the Palmer Archipelago.

Lying to the south-west are Lemaire Island and Paradise Harbour.

Glaciers entering the bay, clockwise from the northeast, include Deville Glacier, Arago Glacier, Moser Glacier, Rudolph Glacier, Bagshawe Glacier and Grubb Glacier.

Coastal features, clockwise from the northeast, include Beneden Head, Neko Harbour, Forbes Point, Lester Cove, Dallmeyer Peak, Almirante Ice Fringe, Steinheil Point, Mount Hoegh and Duthiers Point.

It is a glacial fjord, whose mouth is just to the north of an aquatic sill that restricts movement of relatively warm upper layer of circumpolar deep water from the Gerlache Strait into the fjord. The fjord therefore has cold deep water compared to bays further south, and its glaciers mainly lose ice through calving rather than glacial retreat driven by ocean water.

The lack of strong wind combined with the surface freshing cause stratification of salinity to a significant depth in the photic zone. This is hospitable to phytoplankton blooms.[1]

FjordEco Project

In November-December 2015, in April 2016, and in March-April 2017, the United States National Science Foundation conducted research cruises into Andvord Bay as part of their 'FjordEco Project', an integrated field and modelling study. The study sought to evaluate physical oceanographic processes, glacial inputs, plankton dynamics, and benthic community structure and function in the bay.[2]
