Abstract

Estimates of vertical particulate carbon flux and inorganic nitrogen input from rain events were evaluated in relation to horizontal diffusion during a four day study in the Sargasso Sea. Productivity (c300 mg C m-2 d-1) and particulate organic C flux (f-ratio of 0.17) from sediment trap arrays were similar to those recently documented in this region. For small, convective rain events, diffusion may be as important as phytoplankton uptake in reducing nitrogen concentrations to ambient nanomolar levels. -from Authors
