Phytoplankton Bloom in the Barents Sea [Detail]

NASA image acquired August 31, 2010 To see the full view of this image go to: <a href="http://www.flickr.com/photos/gsfc/4970549945">www.flickr.com/photos/gsfc/4970549945</a> In this natural-color image from August 31, 2010, the ocean’s canvas swirls with turquoise, teal, navy, and green, the abstract art of the natural world. The colors were painted by a massive phytoplankton bloom made up of millions of tiny, light-reflecting organisms growing in the sunlit surface waters of the Barents Sea. Such blooms peak every August in the Barents Sea. The variations in color are caused by different species and concentrations of phytoplankton. The bright blue colors are probably from coccolithophores, a type of phytoplankton that is coated in a chalky shell that reflects light, turning the ocean a milky turquoise. Coccolithophores dominate the Barents Sea in August. Shades of green are likely from diatoms, another type of phytoplankton. Diatoms usually dominate the Barents Sea earlier in the year, giving way to coccolithophores in the late summer. However, field measurements of previous August blooms have also turned up high concentrations of diatoms. The Barents Sea is a shallow sea sandwiched between the coastline of northern Russia and Scandinavia and the islands of Svalbard, Franz Josef Land, and Novaya Zemlya. Within the shallow basin, currents carrying warm, salty water from the Atlantic collide with currents carrying cold, fresher water from the Arctic. During the winter, strong winds drive the currents and mix the waters. When winter’s sea ice retreats and light returns in the spring, diatoms thrive, typically peaking in a large bloom in late May. The shift between diatoms and coccolithophores occurs as the Barents Sea changes during the summer months. Throughout summer, perpetual light falls on the waters, gradually warming the surface. Eventually, the ocean stratifies into layers, with warm water sitting on top of cooler water. The diatoms deplete most of the nutrients in the surface waters and stop growing. Coccolithophores, on the other hand, do well in warm, nutrient-depleted water with a lot of light. In the Barents Sea, these conditions are strongest in August. The shifting conditions and corresponding change in species lead to strikingly beautiful multicolored blooms such as this one.

The Turbulent Bering Sea [full frame]

Large blooms of phytoplankton (likely coccolithophores) surrounded the 51-kilometer-long St. Matthew Island in the Bering Sea on October 8, 2014 when the above Aqua-MODIS image was collected. The swirls and eddies of color give some indication of the turbulent nature of these waters. The reflective blooms have been visible from orbit for a few months now.

Phytoplankton bloom in the Bay of Biscay

Springtime in the Bay of Biscay, off the coast of France, as in most places, is a season of abundant growth. On April 20, 2013, the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite captured this true-color image of the dynamic growth of a springtime phytoplankton bloom. The swirling colors indicate the presence of vast numbers of phytoplankton – tiny plant-like microorganisms that live in both fresh and salt water. Although these organisms live year-round in the Bay of Biscay, it is only when conditions are right that explosive blooms occur. In spring, the lengthening sunlight, the increased nutrient load swept into the Bay from ocean currents and from snowmelt carried by freshwater rivers, combined with warming waters create the perfect conditions to spur phytoplankton in to tremendous growth. The result is a swirling, multi-hued discoloration that can be easily seen from space. Each year, typically from March through April, such blooms occur in the Bay of Biscay. By May, however, conditions are not as favorable and the blooms fade, then disappear.

Phytoplankton bloom in the Bay of Biscay

Phytoplankton growth in the Bay of Biscay intensified in early May, 2013, painting the deep blue waters with huge swirls of jewel-tone colors that were brilliantly visible from space. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite captured this true-color image on May 4, 2013. Each year, typically from March through April, such blooms occur in the Bay of Biscay. By May, however, conditions are not as favorable and the blooms tend to fade, then disappear. This bloom is expanding in early May this year, but will likely begin to diminish soon.
