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