Moored Observations for the Forced Upper Ocean Dynamics Experiment in the Arabian Sea
Abstract
My long-term goals are to understand how biological processes in the ocean affect, and are affected by, physical processes (mixing, stirring, and the penetration of light into the ocean). I want to figure out how irradiance and wind-stress influence the dynamics of the upper ocean, how these dynamics govern the rate and nature of primary production, and ultimately, the growth of phytoplankton populations. I also want to understand the feedback between the changes in phytoplankton biomass and the variability in optical properties of the sea, and to use the absorption and scattering properties of phytoplankton to predict photosynthesis and growth. The specific scientific objectives of this grant are as follows: (1) determine the diurnal, within-season, and seasonal variability of phytoplankton for a locale subject to strong seasonal wind-stress; (2) understand how POC:Chl changes with the advent of the SW monsoon; (3) determine whether the seasonal increase in phytoplankton affects the surface heating of the water column; and (4) determine whether the chlorophyll-specific primary production is constant throughout the year in the Arabian Sea, where strong seasonal signals in nutrients are characteristic.
