Argentina - July 23rd, 2011

Sediments line the coastline of Argentina by the provinces of Chubut and Santa Cruz. The large, semi-circular indentation is the San Jorge Gulf (Golfo San Jorge), a bay in southern Patagonia that opens to the Atlantic ocean. Its shoreline spans both of the aforementioned provinces.

The gulf measures approximately 142 miles (229 km) at its mouth and covers approximately 39 square kilometres (15 sq mi). It is located between Cape Dos Bahías and Cape Tres Puntas. Due to its geography, more than 70% of the gulf’s basin is between 70 metres (230 ft) and 100 metres (328 ft) deep. To the south it is about 50 metres (164 ft) 60 metres (197 ft) deep and in the north 90 metres (295 ft).

Visible in the lower right quadrant are the Falkland Islands (Islas Malvinas), an archipelago in the South Atlantic Ocean, located about 250 nautical miles (290 mi; 460 km) from the coast of mainland South America.
