Marguerite Bay (Bahía Margarita), on the west coast of the southern tip of the Antarctic Peninsula, was chosen for its relatively mild climate and friendly shores to be the location of several antarctic polar stations. I've written about Rothera (UK) sometime ago, and in its vicinity is San Martin, an Instituto Antártico Argentino (IAA) base.
Marguerite Bay is a large and deep bay, but the access is quite difficult most of the year because the water surface is frozen, or dangerously covered with moving ice floes. Small islands, underwater cliffs and rocks compose a net of narrow navigable canals. Only during the short antarctic summer is the route easy for supply ships as well as for tourist cruises or scientific expeditions.
Barry Island was first charted by the British Graham Land Expedition (BGLE) under John Riddoch Rymill, who used it for a base in 1936 and 1937. He also named it after the eldest son of an expedition member.
Coordinates: 68° 07´ S , 67° 06´ W
350 km south of the Antarctic circle.
Occupation: ~ 20, all year round.
Base San Martín is a permanent, all year-round Antarctic base for scientific research on climate, seismology and geodesics.
A quick description: one two-story main house with double wooden walls, an emergency house, five metal warehouses for supplies, housing for the dog packs, a power generator and the four towers for the 25 meters high antenna.
The IAA meteorological station within the base has been for long providing detailed weather records and developing forecasts for the navigation of the sea waters adjacent to the Antarctic Peninsula.
In order to transport the personnel and materials to Marguerite Bay, the navy has several polar ships, some with ice-breaking capacities.
All emergency - supply, rescue missions - are usually done by helicopter, and in winter relief crew comes by helicopter transfer. In adequate weather conditions, the team can also be reached by plane.
Two Glaciars - Uspallata and McClary - face Barry Island. Now, just look how magnificent is Marguerite Bay and its glaciars at sunset, or during the midnight sun by the antarctic summer solstice:
