Argentina – September 24th, 2012

Sediments line the coast of the Argentine provinces of Santa Cruz and Tierra del Fuego, both part of Patagonia, from the San Jorge Gulf to the Mitre Peninsula.

Visible parallel to the west coast are the Andes Mountains, along the border with Chile. Visible by the mountains are several bright blue glacial lakes (from north to south): Lake O’Higgins/San Martín (the former name is used in Chile, the latter in Argentina), Viedma Lake and Argentino Lake.

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 - 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.

This orthorectified image shows two of the eight Channel Islands of California, Santa Cruz (right) and Santa Rosa (left). The islands are located in the Pacific Ocean off the coast of Southern California, along the Santa Barbara Channel in the United States of America.

Santa Cruz is 22 miles (35 km) long and from 2 to 6 miles (3.2 to 9.7 km) wide. At 61,764.6 acres (249.952 km2 or 96.507 sq mi), it is the largest of the eight islands in the chain. The coastline has steep cliffs, gigantic sea caves, coves, and sandy beaches. The highest peak is Devils Peak, at 2450+ feet (747+ m).

Santa Rosa Island is the second largest of the chain, at 53,195 acres (215.27 km² or 83.118 sq mi). It is occupied by rolling hills, deep canyons, a coastal lagoon and beaches adorned with sand dunes and driftwood. Its highest peak is Vail Peak, at 1,589 feet (484 m).
