Phytoplankton in Barents Sea - September 9th, 2011

The phytoplankton bloom in the Barents Sea Eosnap had originally observed off the northern coast of Norway can now be seen north of the coast of Russia.

This part of the bloom is located in the Arctic Circle, in the waters north of the Kola Peninsula (left central edge to center), which shares a border with Norway, and northwest of the Kanin Peninsula (right).

Great Bear Lake, covered in ice, to the right, is the largest lake entirely within Canada (Lake Superior and Lake Huron straddling the Canada-US border are larger). It is the third largest in North America, and the seventh largest in the world.

The lake is situated on the Arctic Circle between 65 and 67 degrees of northern latitude and between 118 and 123 degrees western longitude, 186 m (610 ft) above sea level. It empties through the Great Bear River (Sahtúdé) into the Mackenzie River.

Great Bear Lake has a surface area of 31,153 km2 (12,028 sq mi) and a total volume of 2,236 km3 (536 cu mi). Its maximum depth is 446 m (1,463 ft) and its average depth 71.7 m (235 ft). The total shoreline is 2,719 km (1,690 mi) and the total catchment area of the lake is 114,717 km2 (44,292 sq mi).

The landscape of Alaska’s North Slope Borough is dotted by many lakes in this orthorectified image. The borough has a total area of 94,763 square miles (245,436 km²), of which, 88,817 square miles (230,035 km²) of it is land and 5,946 square miles (15,399 km²) of it (6.27%) is water.

Its western coastline is along the Chukchi Sea, while its eastern shores, beyond Point Barrow, are on the Beaufort Sea (visible in the top part of this image). Here, the Colville River can be seen crossing the North Slope and spilling into the Beaufort Sea.

The Colville is a major river of the Arctic Ocean coast of Alaska in the United States, approximately 350 mi (560 km) long. One of the northernmost major rivers in the North America, it drains a remote area of tundra on the north side of the Brooks Range entirely above the Arctic Circle. The river is frozen for more than half the year and floods each spring.

Upon opening the full image, the river can be seen flowing through the foothills on the north side of the Brooks Range, broadening as it receives the inflow of many tributaries that descend from the middle Brooks Range. After flowing across the Arctic plain, it enters the western Beaufort Sea in a broad delta near Nuiqsut, approximately 120 mi (190 km) west of Prudhoe Bay.

Svalbard Archipelago, Norway - June 2nd, 2009

The Svalbard Archipelago is a group of islands in the Arctic Ocean that forms the northernmost part of Norway and the northernmost lands of Europe.

The islands cover an area of 61,022 km², of which about 60% (36,502 km²) is covered by glaciation. Three large islands dominate: Spitsbergen (upper right), Nordaustlandet (top center) and Edgeøya (above Spitsbergen).

The swirled patterns in the ocean near the islands are created when sea ice freezes or melts.

Svalbard lies far north of the Arctic Circle. In Longyearbyen, the midnight sun lasts from April 20 to August 26, and polar night lasts from October 26 to February 15.

From November 12 to the end of January there is civil polar night, a continuous period without any twilight bright enough to permit outdoor activities in the absence of artificial light.
