摘要

Relative to other parts of the western tropical Indian Ocean, the study area off the coast of Tanzania (05°29.28□S, 40°56.01□ E) has a characteristically unique environment. Studies of the modern day oceanographic conditions on this side of the Indian Ocean suggest that the area has stratified waters year round, a steady thermocline, and relatively low surface-water productivity. In general, the surface waters of the western Indian Ocean are governed by seasonally reversing monsoon winds that lead to upwelling and downwelling in the ocean, which in turn affect the nutrient availability and surface-water productivity. Coccolithophores are the most common primary producers of the world's oceans and are found to respond directly to variations in temperature, salinity, and nutrient availability.
