   On September 17, 2020, the Moderate Resolution Imaging
   Spectroradiometer (MODIS) on board NASA’s Terra satellite acquired a
   true-color image of a sunny summer day over England and Wales.

   Heavy sediment fills Bristol Bay between England and Wales. Both
   countries sit on the island of Great Britain, with Wales bounded by
   Bristol Bay in the south and the Irish Sea in the west. England makes
   up the greater part of the island, with Scotland (not seen in this
   image) sitting in the north.

   Not only does sediment fill Bristol Bay, but sediment clings to the
   coastlines in the southeast, especially near the outflow of the River
   Thames. Tans and greens swirls are also seen in all the water
   surrounding the island, including the North Sea, the English Channel,
   and the Irish Sea. The greenish color may represent either sediment,
   which changes reflectivity as it sinks and thus can appear green, or
   blooms of phytoplankton. Or a mix of both. Phytoplankton are
   microscopic, plant-like organisms that live in the waters in this
   region year-round. When conditions are right, they can reproduce in
   huge numbers, creating blooms that can be easily seen from space.
