Research topic: Global synthesis of deep ocean carbon, carbonate, opal, and nutrient particle fluxes, benthic fluxes and sediment accumulation
We request support to synthesize sea floor flux and sediment composition measurements into a global description of biogenic fluxes in the deep ocean and sediments to provide the basis for testing models of organic matter fluxes. This work will be comprised of three specific activities.
The development of an accurate understanding of global biogenic fluxes will require the synthesis of satellite, process, time-series and sea floor studies, each providing unique information. Sea floor studies, while not constraining temporal variability at the same time-scale as surface water processes, provide an assessment of the spatial distribution of deep fluxes not attainable by process and time-series studies and not visible by satellites. Sea floor studies further provide the link between ocean processes and the sediment record upon which paleoceanographic reconstructions depend. By providing improved quantitative descriptions of deep water column fluxes, benthic fluxes and sediment accumulation rates, this project will contribute to the following SMP objectives:
