Today’s Image of the Day from NASA Earth Observatory features a shallow freshwater lake located on the border of Russia and northeastern China known as Lake Khanka.
The striking green swirls in the water most likely represent the presence of chlorophyll-rich phytoplankton.
According to NASA, phytoplankton and other suspended solids in the lake are easily mixed by the wind.
The image was captured on April 12, 2019 by the Operational Land Imager on Landsat 8.
