Summary of Field Work: |
Since 1978, the Oceanic Flux Program (OFP) has continuously measured particle fluxes in the deep Sargasso Sea. The 37+ year time-series is the longest of its kind and has produced a unique record of temporal variability in the "biological pump", a term loosely applied here to material transfer from the surface to deep ocean resulting from upper ocean biological/physical processes. Two overarching goals drive core activities funded under the OFP grant. The first is to extend the time-series by collection of new samples that are of the highest possible quality and that have maximal oceanographic context. The second is to elucidate the causal processes that drive oceanic particle flux through comparative studies of flux magnitude and composition, and concurrent observations of external forcing (e.g. synoptic scale meteorology, climate patterns), surface water physics and biology (e.g. mesoscale features, blooms, etc.), and interior processes (e.g. particle aggregation/disaggregation, midwater scavenging). |
