Off the coast of France (bottom right) and the United Kingdom (top right), microscopic marine plants known as phytoplankton are blooming in the waters of the Atlantic Ocean, coloring the ocean blue and green. The Bristol Channel, which separates England from Wales, appears filled with murky water. The tan color could be a mixture of sediment and organic matter flowing into the Channel from rivers and streams as well as material churned up by waves and tidal actions.
