falkland Islands - December 27th, 2011

The Falkland Islands (Spanish: Islas Malvinas) are an archipelago in the South Atlantic Ocean, located about 250 nautical miles (290 mi; 460 km) from the coast of mainland Argentina. This image focuses on East Falkland (Spanish: Isla Soledad). Visible in the Atlantic to the south is a blue phytoplankton bloom.

East Falkland is the largest of the Falkland Islands, with an area of 6,605 km2 (2,550 square miles) and a coastline 1,036.9 mi (1,668.7 kilometres) long. The island is almost bisected by two deep fjords, Choiseul Sound and Brenton Loch-Grantham Sound which leaves the northern portion and Lafonia in the south, connected only by an isthmus just under 1.5 miles (2.4 km) wide. The island contains many smaller bays, inlets and headland.

Argentina - October 20th, 2011

Sediments can be seen near Cape Tres Puntas, Santa Cruz Province, Argentina, the southern limit of the semi-circular San Jorge Gulf.

Visible to the southeast of the cape are the Falkland Islands, an archipelago in the South Atlantic Ocean, located about 250 nautical miles (290 mi; 460 km) from the coast of mainland South America. The ocean water to the south of the islands appears slightly bluish in color, indicating the presence of phytoplankton.

Argentina - August 25th, 2011

Sediments from the Naposta Stream line the shores of Argentina near the city of Bahía Blanca. The irregularly shaped landform down the coast to the south is Peninsula Valdes.

Continuing down the coast in the full image, one crosses the San Jorge Gulf and can observe the shoreline as far as Ushuaia. Northeast of Ushuaia are the Falkland Islands (known in Argentina as the Islas Malvinas).

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.

Argentina - February 10th, 2011

The thumbnail image focuses on the rugged coastline of the Falkland Islands (also known as the Islas Malvinas). East Falkland (Isla Soledad) is situated to the right, while West Falkland (Isla Gran Malvina) is to the left.

The two main islands are sepearted by the Falkland Sound (Spanish: Estrecho de San Carlos) is a sea strait running southwest to northeast. Other smaller islands are present in the strait.

In the full image, a faint phytoplankton bloom can be observed to the east of the islands. The very light color suggests that the bloom is either just beginning or just ending; bright colors would indicate a much higher concentration of organisms in the water.
