| contents | Temporal and spatial variability of phytoplankton pigment concentrations in the Indian Ocean, derived from the CZCS time series images Abul B.M. Alauddin Talukder Ciencias de la Tierra monsoon Indian Ocean Coastal Zone Color Scanner phytoplankton pigment concentration A total of 93 monthly global composite remotely sensed ocean color images from the Coastal Zone Color Scanner (CZCS)on board the Nimbus-7 satellite were extracted for the Indian Ocean region (35ºN55ºS; 30120ºE) to examine the seasonalvariations in phytoplankton pigment concentrations, resulting from large-scale changes in physical oceanographic processes. TheCZCS data sets were analyzed with the PC-SEAPAK software, and revealed large phytoplankton blooms in the northwestArabian Sea and off the Somali coast. The blooms were triggered by wind-driven upwelling during the southwest monsoonalmonths of August and September. In the northern Arabian Sea, phytoplankton blooms, detected from January to March, appearedto be associated with nutrient enhancement resulting from winter convective mixing. In the Bay of Bengal, higher pigmentconcentrations were confined to the coastal regions but varied only marginally between seasons both in the coastal and offshoreregions. Phytoplankton pigment concentrations were consistently low in the open Indian Ocean. Analysis of pigmentconcentrations extracted from the monthly-accumulated images revealed that the Arabian Sea sustained a greater biomass ofphytoplankton compared with any other region of the Indian Ocean. Overall, the coastal regions of the Indian Ocean are richer inphytoplankton pigment than the open Indian Ocean. The number of images in individual areas was highly variable throughout theregion due to varying cloud cover. 2005 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48031305 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.3 Vol.31 |
