EL GOLFO DE TEHUANTEPEC Y ÁREAS ADYACENTES: VARIACIÓN ESPACIOTEMPORAL DE PIGMENTOS FOTOSINTÉTICOS DERIVADOS DE SATÉLITE THE GULF OF TEHUANTEPEC AND ADJACENT AREAS: SPATIAL AND TEMPORAL VARIATION OF SATELLITE-DERIVED PHOTOSYNTHETIC PIGMENTS

摘要: Photosynthetic pigment concentrations retrieved from data generated 1978 to 1986 by the sensor Coastal Zane Color Scanner were used describe seasonal and interannual variation of phytoplankton biomass Gulf Tehuantepec adjacent areas. The 0.3 mg m’ higher considered as an index productive waters. Its spatial coverage shows coastal upwelling in gulfs Papagayo (in eastern region study area) between October April. at Costa Rica dome during summer. transient effect mixing tropical storms July throughout area. Ilpwelling events Central America are not synchronous. west Tchuantepec is oligotrophic most time (CO.2 mm’). evident was El Nino 1982-1983, with very low associated a deep thermocline whole Also, there anti-El event 1985 region, high shallow thermocline.
