SUMMARY:Particle flux in the deep Sargasso Sea: Insights from the Oceanic 
 Flux Program time series - Maureen Conte (WHOI)

DESCRIPTION:Sinking particles carry with them many different elements and 
 organic compounds\, some of which are essential to support life. The depth
 s at which these are dissolved and then redistributed by ocean currents to
  rise again to the surface controls nutrient distributions that regulate t
 he ocean’s productivity and the global cycles of many elements. The flux
  of carbon controls the rate at which oceans can adsorb atmospheric carbon
  dioxide\, and the flux of organic materials provides the fuel to support 
 life below the sunlit surface ocean. Additionally\, the residual flux mate
 rial that survives remineralization to be preserved in ocean sediments car
 ries with it many details about past ocean conditions that can be used to 
 reconstruct the earth's history. \n\nSince 1978\, the Oceanic Flux Program
  (OFP) sediment trap time-series has continuously measured the deep partic
 le flux in the northern Sargasso Sea near Bermuda. The OFP has produced a 
 seminal record of variability in flux magnitude and composition at time-sc
 ales of weeks to decades. This talk will provide an overview of the OFP ti
 me-series and current OFP studies that have elucidated key processes contr
 olling elemental flux and cycling within the water column. \n
