- Abstract:
- We will measure biogenic silica (BSi) production in the Atlantic Ocean from 50?N to 50?S to 1) assess the role of diatoms relative to coccolithophores in driving the export of particulate matter from upper ocean oligotrophic waters and 2) understand the mechanisms by which diatoms grow in ultraoligotrophic regions. Objective 1 will be achieved by comparing BSi production data to opal fluxes at the base of the euphotic zone derived from 234Th deficits and 234Th /opal ratios on sinking particles and estimates of calcite export from calcification measurements, 234Th deficits and calcite/234Th ratios on sinking particles. Objective 2 will be achieved by conducting kinetics experiments on natural diatom populations from a range of depths.
