Ocean Color Gallery, late summer 2019

Released on September 17, 2019

A selection of images from https://oceancolor.gsfc.nasa.gov/gallery/ from late summer 2019.

In what appears to be the new summertime normal, a large portion of the Baltic Sea is once again choked by thick, slick-forming cyanobacteria blooms. This view was collected by Landsat 8 on July 19, 2019.

This Landsat 8 scene shows the Kolyma River delivering its load of suspended sediments and colored dissolved organic matter to the Arctic Ocean which remained ice covered just north of the river's mouth on June 16, 2019 when the image was collected.

The Yenisei River exports large quantities of sediment and organic carbon to the Arctic Ocean. The above Lansat 8 image was collected on July 17, 2019. It shows the waters mixing where the Yenisei estuary widens out into the Kara Sea by the ice-flanked Sibiryakov Island.

This Landsat 8 view of southwestern Greenland was collected on August 29, 2019. It shows meltwater loaded with glacial sediments flowing into the Davis Strait.

Excessive heat drove accelerated melting across Greenland during the summer of 2019. The above Aqua/MODIS composite shows melt ponds and grayish patches that indicate bare ice and wet snow along the southwest coast — results of the warming. Offshore, plumes of turquoise melt water flow into the Davis Strait and mingle with the blooming phytoplankton there. The data comprising the above image were collected on August 29, 2019.

When Hurricane Dorian passed over the Bahamas and along the southeastern United States coastline, its waves resuspended large quantities of sea-floor sediment which give the ocean a milky, aquamarine appearance in the above composite of VIIRS data collected on September 7, 2019. The browner hues closer to the U.S. shore come from runoff generated by the heavy rainfall of the hurricane.

This is the season for Trichodesmium blooms along the Great Barrier Reef in Australia. This Landsat 8 image collected on September 2, 2019 shows long, linear, yellowish features in the Capricorn Channel and along the coastline that are most likely slicks of those nitrogen-fixing cyanobacteria.
