Phytoplankton in Barents Sea - August 14th, 2011

This image shows a striking green and blue phytoplankton bloom in the Barents Sea, between Norway’s  Svalbard Archipelago (visible at the upper left of the full image) and the Norwegian mainland. Also visible at the left edge is Bear Island (Norwegian: Bjørnøya), the southernmost island of the Svalbard archipelago.

When conditions are right, phytoplankton populations can grow explosively, a phenomenon known as a bloom. Blooms in the ocean, such as the one visible here, may cover hundreds of square kilometers and are easily visible in satellite images. Although a bloom may last several weeks, the life span of any individual phytoplankton is rarely more than a few days.

Svalbard Archipelago, Norway - June 2nd, 2009

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.
