dc.description.abstractEl objetivo de la presente investigación, fue diagnosticar las áreas de mayor productividad biológica en base a Clorofila "a" superficial y subsuperficial, durante la década 1989-1999 para la región del Pacífico Tropical (Ecuador).es
dc.description.abstractDuring 1988-1999 were carried out 23 oceanographic cruise on board the B/I-ORION of the Instituto Oceanográfico de la Armada (INOCAR) in the Tropical Pacific Equatorial. The study area was a geographical location among 81°W-94°W y 2°N - 3.23°S of Ecuador. This data were contained by seasonal category, with a total of 23 cruises, 486 stations and 3187 data to chlorophyll sampling in 8 levels of depth (0, 10, 20, 30, 40, 40, 50, 75m). The results emphasized two areas of more productivity. 1) In Galapagos this upwelling were presented with the high biomass of chlorophyll >0.5 mg/m³, was presented toward the south region of Galapagos. Other nucleus of 1.5 mg/m³ among Island Isabela and Fernandina in dry seasonal. In the humid seasonal was registered two nuclei (1.0 mg/m³), a nucleus to the west of Galapagos associated with Cromwell Current and another nucleus to Island San Cristobal southeast possibly associated with a mixture of upwelling Cromwell and Humboldt. 2) In Gulf of Guayaquil: it is the high estuary in profile of the South American Pacific, present nuclei among 1 to 3 chlorophyll mg/m³. At level subsuperficial the biggest density was located among the 0 to at 30m of depth, condition that varies depending on the intensity of the area of mixtures of appeared waters and warm waters lightly. During events El Niño the chlorophyll biomass diminished with values <0.2 mg/m³, due to the discontinuity of the upwelling and/or masses of waters warm poor in nutrients. These areas of more biological productivity in chlorophyll "a" to they would be associated to the areas of more captures of fishing pelagic and of the Tuna.en
