Laguna de Términos on the Yucatan Peninsula, Mexico18.6N 91.5W
The Laguna de Términos (Términos Lagoon), in the lower left quadrant, is located along the coast of the Yucatán Peninsula in Mexico. It is made up of a series of rich, sediment-laden lagoons and tidal estuaries connected by two channels to the Bay of Campeche in the southern part of Gulf of Mexico.
The lagoon is about 112.5 square km in area (about 50 miles long and 20 miles wide). Twenty-nine percent of the lagoon is covered with seagrass, and its are swampy and support mangroves.
It is fed with fresh water by several rivers, including the Mezcapala, Grijalva and Usumacinta Rivers. Every nine days, approximately 50% of the lagoon’s water volume is renewed, primarily through the effect of ocean tides.
