The Gulf of Tehuantepec and adjacent areas: spatial and temporal variation of satellite-derived photosynthetic pigments

Photosynthetic pigment concentrations retrieved from data generated from 1978 to 1986 by the sensor Coastal Zane Color Scanner were used to describe the seasonal and interannual variation of phytoplankton biomass of the Gulf of Tehuantepec and adjacent areas. The pigment concentrations 0.3 mg m–3 an...

The pigment concentrations 0.3 mg m–3 and higher were considered as an index of productive waters.

Upwelling events in Tehuantepec and Central America are not synchronous. The region west of the Gulf of Tehuantepec is oligotrophic most of the time (less than 0.2 mg m–3). The most evident interannual variation was the effect of El Niño 1982–1983, with very low pigment concentrations associated with a deep thermocline in the whole study area.

Las concentraciones de 0.3 mg m–3 y mayores fueron consideradas como índice de aguas productivas. Su cobertura espacial muestra las surgencias costeras de los golfos de Tehuantepec y Papagayo (en la región oriental del área de estudio) entre octubre y abril, la surgencia del domo de Costa Rica en verano y el efecto episódico de mezcla por tormentas tropicales de julio a octubre en toda el área de estudio. Los eventos de surgencia de Tehuantepec y Centroamérica no son sincrónicos. La región al occidente de Tehuantepec es oligotrófíca la mayor parte del tiempo (menor que 0.2 mg mm–3). La variación interanual mas evidente fue el efecto de El Niño 1982–1983, con muy bajas concentraciones de pigmentos asociadas con una termoclina profunda en toda el área de estudio. Además, hubo un evento anti-El Niño en 1985 en la región oriental, con concentraciones elevadas de biomasa fìtoplanctónica asociadas con una termoclina somera.
