Ocean Carbon and Biogeochemistry http://us-ocb.org/ Ocean Carbon and Biogeochemistry The Ocean Carbon and Biogeochemistry (OCB) program focuses on the ocean's role as a component of the global Earth system, bringing together research in geochemistry, ocean physics, and ecology that inform on and advance our understanding of ocean biogeochemistry. The overall program goals are to promote, plan, and coordinate collaborative, multidisciplinary research opportunities within the U.S. research community and with international partners. Important OCB-related activities currently include: the Ocean Carbon and Climate Change (OCCC) and the North American Carbon Program (NACP); U.S. contributions to IMBER, SOLAS, CARBOOCEAN; and numerous U.S. single-investigator and medium-size research projects funded by U.S. federal agencies including NASA, NOAA, and NSF. The scientific mission of OCB is to study the evolving role of the ocean in the global carbon cycle, in the face of environmental variability and change through studies of marine biogeochemical cycles and associated ecosystems. The overarching OCB science themes include improved understanding and prediction of: 1) oceanic uptake and release of atmospheric CO2 and other greenhouse gases and 2) environmental sensitivities of biogeochemical cycles, marine ecosystems, and interactions between the two. The OCB Research Priorities (updated January 2012) include: ocean acidification; terrestrial/coastal carbon fluxes and exchanges; climate sensitivities of and change in ecosystem structure and associated impacts on biogeochemical cycles; mesopelagic ecological and biogeochemical interactions; benthic-pelagic feedbacks on biogeochemical cycles; ocean carbon uptake and storage; and expanding low-oxygen conditions in the coastal and open oceans. OCB largerWorkCitation program MedFlux collaborative research project http://www.msrc.sunysb.edu/MedFlux/ MedFlux collaborative research project <p class="text">The MedFlux collaborative research project will<br /> test two hypotheses of the influence of "ballast" on the flux of<br /> particulate matter through the water column. It either 1)<br /> acts as a physical shielding of the organic matter protecting it as it<br /> falls through the water column, or 2) is the ratio of<br /> mineral ballast to organic carbon that controls the sinking<br /> velocity and consequently the organic carbon flux to the deep<br /> sea. The project has two major objectives:</p> <ol> <li>To assess the extent to which settling velocity separation techniques accurately and reliably measure in-situ settling velocities and to devise mechanical improvements and/or statistical correction procedures to overcome any deficiencies.</li> <li>To develop perspectives and protocols that take advantage of the different sampling characteristics of in-situ pumps, sediment traps, and optical instruments, combined with radiochemical analysis, to assess the dependence of settling velocity and remineralization on particle size and the organic and inorganic composition of particles.</li> </ol> <p><strong>Project description from the NSF award page:<br /> <br /> Collaborative Research: Mineral Ballast and Organic Matter Compositions as Determinants of Particle Settling Velocities and Fluxes in the Sea (MedFlux) </strong></p> <p> Sinking particulate matter is the major vehicle for exporting carbon from the sea surface to the ocean interior. During its transit towards the sea floor, most (&gt;90%) particulate organic carbon (POC) is returned to inorganic form and redistributed in the water column. This redistribution determines the depth profile of dissolved CO₂, which in turn determines the concentration of CO2 in the surface mixed layer, and hence the rate at which the ocean can absorb CO₂ from the atmosphere. It also determines the depth profile of nutrient regeneration, which determines the time scale of return of mineral nutrients to the photic zone. The ability to predict quantitatively and mechanistically the depth profile of remineralization is therefore critical to predicting the response of the global carbon cycle to environmental change. </p> <p>Minerals typically constitute more than half the mass of particles sinking out of the ocean surface, and this fraction increases dramatically with depth. Marine plankton contribute biominerals, e.g., opal by diatoms and radiolarians, and CaCO₃ by coccolithophorids and foraminifera. Detrital minerals (largely quartz and aluminosilicates) introduced from land by rivers and wind also can become associated with marine plankton (or their remains) through sorption and aggregation processes. Minerals are important for making less dense organic matter (OM) sink, and may also protect OM from degradation, allowing it to penetrate deeper into the ocean. </p> <p>Prior to the inception of MedFlux, investigators demonstrated that ratios of particulate organic carbon to mineral ballast converge to a nearly constant value (~3-7 wt% POC) at depths &gt;1800 m (Armstrong et al. 2002), and Klaas &amp; Archer (2002) demonstrated that the variability in the data can largely be explained by the chemical composition of the ballast (opal vs. carbonate vs. dust). The focus of MedFlux is to develop a better mechanistic understanding of this “ballast hypothesis”. In particular, given the many processes that could cause large deviations from this ratio, a fundamental goal is to understand why POC:mass ratios seem to be well-delimited, and to use this understanding to create, as fully as possible, a new mathematical description of remineralization to replace those currently in use. This last goal is of utmost significance if, for example, lowered pH causes carbonate minerals to dissolve preferentially, affecting both ballasting and the average remineralization depth of POC in the ocean.</p> <p>MedFlux is a collaborative research project that includes investigators from the U.S. and Europe. <br /> Robert Armstrong, Stony Brook University, Stony Brook, NY <br /> Kirk Cochran, Stony Brook University, Stony Brook, NY <br /> Anja Engel, Alfred Wegener Institute, Bremerhaven, Germany <br /> Scott Fowler, Stony Brook University, Stony Brook, NY <br /> Madeleine Goutx, CNRS/Université de la Mediterranee (aix-Marseille) Marine Microbiology Laboratory, France <br /> Cindy Lee, Stony Brook University , Stony Brook, NY <br /> Pere Masqué, Universitat Autonoma de Barcelona, Spain <br /> Juan Carlos Miquel, IAEA Marine Environment Laboratories, Monaco <br /> Michael Peterson, University of Washington, Seattle, WA <br /> Olivier Rageneau, Institute Universitaire Europeen de la Mer, Brest, France <br /> Richard Sempéré, CNRS/Université de la Mediterranee (aix-Marseille) Marine Microbiology Laboratory, France <br /> Gillian Stewart, Queens College, NYC, NY <br /> Christian Tamburini, CNRS/Université de la Mediterranee (aix-Marseille) Marine Microbiology Laboratory, France <br /> Stuart Wakeham, Skidaway Institute of Oceanography, Savannah, GA </p> <p><strong>Publications:</strong><br /></p> <p>Goutx, M., Wakeham, S.G., Lee, C., Duflos, M., Guigue, C., Liu, Z., Moriceau, B., Sempéré, R., Tedetti, M., and Xue, J..

Instrument Name: Sediment Trap - IRS Instrument Short Name:Sed Trap - IRS Instrument Description: Sediment traps are specially designed containers deployed in the water column for periods of time to collect particles from the water column falling toward the sea floor. In general a sediment trap has a jar at the bottom to collect the sample and a broad funnel-shaped opening at the top with baffles to keep out very large objects and help prevent the funnel from clogging. The Indented Rotating Sphere (IRS) Sediment Trap is described in Peterson et al. (Field evaluation of a valved sediment trap. 1993. Limnology and Oceanography, 38, pp. 1741-1761 and Novel techniques for collection of sinking particles in the ocean and determining their settling rates. 2005. Limnology and Oceanography Methods 3, pp. 520-532). The IRS trap consists of four cylindrical modules; a particle interceptor, an IRS valve; a skewed funnel, and an eleven sample carousel (designated IRSC trap). The key to the trap design is the patented IRS valve located between the particle interceptor and particle accumulator portions of the trap. The valve and carousel are regulated by a TattleTale IVA (manufactured by Onset Computer Corp.) microprocessor and custom software. The IRS sediment trap was specifically designed to exclude zooplankton (Trull et al. 2008. Deep-Sea Research II v.55 pp. 1684-1695).
