Today’s Image of the Day from NASA Earth Observatory features the stunning colors produced by blooms of phytoplankton in the Chukchi Sea off the coast of Alaska. Striking seawater colored by phytoplankton blooms and shows the beautiful colors in image above.

As the Arctic sea ice retreats each spring, the phytoplankton blooms create brilliant blue and green patterns in the water. A microscopic form of algae known as a diatom is one of the most common types of phytoplankton in the ocean, and generates radiant shades of green.

This image was captured on June 18 by the Operational Land Imager (OLI) on Landsat 8.

Chukchi Sea (Russian: Чуко́тское мо́ре, tr. Chukotskoye more, IPA: [tɕʊˈkotskəjə ˈmorʲɪ]), sometimes referred to as the Chuuk Sea, Chukotsk Sea or the Sea of Chukotsk, is a marginal sea of the Arctic Ocean. It is bounded on the west by the Long Strait, off Wrangel Island, and in the east by Point Barrow, Alaska, beyond which lies the Beaufort Sea. The Bering Strait forms its southernmost limit and connects it to the Bering Sea and the Pacific Ocean. The principal port on the Chukchi Sea is Uelen in Russia. The International Date Line crosses the Chukchi Sea from northwest to southeast. It is displaced eastwards to avoid Wrangel Island as well as the Chukotka Autonomous Okrug on the Russian mainland. Striking seawater colored by phytoplankton blooms often in this area showing a large amount of amazing colors.
