Phytoplankton and Sediments along Western Coast of Yucatan Peninsula19.5N 89W
Bright blue and green phytoplankton, mixed with sediments, float off the coast of the Yucatán Peninsula, particularly on the western side.
The shores of the Isthmus of Tehuantepec, where the distance between the Gulf of Mexico and the Pacific Ocean is shortest, however, are relatively clear.
The Yucatan peninsula, a karstic tropical region shared by Mexico, Belize and Guatemala, frequently experiences phytoplankton blooms.
These blooms are often fed by nutrients in surface runoff, which rivers deposit into the ocean. Here, sediment outflow is particularly noticeable near the Términos Lagoon, the large green lagoon just right of the center.
