The South Atlantic Ocean off the coast of Argentina and Uruguay is a rich mixing bowl of different water masses. The nutrient-rich waters from the combined Paraná and Uruguay Rivers empty into the South Atlantic through the Rio de la Plata. Under the right conditions, especially in spring and early summer, the nutrients fertilize the offshore surface waters allowing for large plankton blooms. This unique image captures traces of several different water masses just southeast of Montevideo, Uruguay, and the Rio de la Plata. Close to the coast of Uruguay, the muddy fresh water plume snakes along the coast. Farther offshore, broad swirls of light blue-green and darker water mark a bloom of plankton. To the right, deep blue water covered by puffy clouds suggests another, warmer water mass just north of the bloom.

In the southeastern corner of the Baltic Sea lies a skinny stretch of land. Known as the Curonian (or Courland) Spit, it separates the Curonian Lagoon (also known as the Courland Lagoon) from the Baltic Sea. Both the spit and the lagoon fall within the borders of Lithuania and Russia’s Kaliningrad Oblast.
