Ocean Carbon and Biogeochemistry

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.

MedFlux collaborative research project

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 (>90%) particulate organic carbon (POC) is returned to inorganic form and redistributed in the water column. This redistribution determines the depth profile of dissolved CO<sub> 2</sub>, which in turn determines the concentration of CO2 in the surface mixed layer, and hence the rate at which the ocean can absorb CO<sub>2</sub> 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 CaCO<sub>3</sub> 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 >1800 m (Armstrong et al. 2002), and Klaas & 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 />

<p><strong>416Filter_*</strong> <br />
From SBE manual, &quot;FILTER can be run before CELLTM to remove any residual response time between the temperature and conductivity sensors and to minimize digitization noise. On average, a low pass filter with a time constant of 0.03 sec reduces the noise in computed salinity slightly.&quot; <br />
for SBE9/11 SBE9plus, older manualSBE4249.txt suggests <br />
Low pass filter B = 0.15s for pressure <br />
Low pass filter A = 0.03s for conductivity <br />
New SBEDataProcessing_5.32a.pdf suggests only .15 for pressure <br />

<h4>OCB DMO processing note:</h4>
<p>The OCB DMO used perl scripts to reformat semi-colon delimited (Seabird-processed .asc) files with Seabird parameter names to space-delimited files with OCB ontology parameter names. All data are from primary (T0 and C0) sensors; and a text file recorded the Seabird/OCB parameter name translation, see: <a href="http://ocb.whoi.edu/MedFlux/PI-NOTES/ctd_EN416_params.txt">ctd_EN416_params.txt</a> <br />

<strong>Important:</strong> station 19 is an uptrace (no downtrace data reported); These comments regarding stations 18 and 19 were recorded in the CTDCastLogandInfo416.xls file <a href="http://ocb.whoi.edu/MedFlux/PI-NOTES/ctd/CTDCastLogandInfo416.pdf">PDF version</a>):<br />

<strong>Station 18:</strong> &quot;HPSS cast. Trip HPBottles then wait for 10min before ascending. FGP P0 = V6 went from 0 to ~0.77 at ~1300m to 2400m downcast then to 2.2 when tripped at 2400m. V6 decreased during upcast - leak in system for FGP Pressure 0. FGP P1 = V7. Fluorometer has high voltage values during downcast ~1600m+ then also on upcast to ~800m. Tripped carousel positions 9-13 two times because FGP1 didn't change when bottle should have tripped. Stopped acquisition at 500m bottle stop. The maximum of 24 positions had been tripped with still 5 bottles to trip. Those remaining 5 were tripped during CTD019.&quot; <br />
<br />
<strong>Station 19:</strong> &quot;HPSS cast. This cast started at 500m after ending CTD018 at 500m bottle-tripping stop during the upcast. The maximum of 24 bottle positions were fired during CTD018 to double check that High Pressure bottle tripped. Thus acquisition had to be restarted to trip remaining bottles. Niskin bottle GOEX109 bottom cap broke before CTD017, replaced w/OTE112.&quot;</p>

CTD Sea-Bird 9
CTD Sea-Bird 9
PI Supplied Instrument Name: CTD Sea-Bird 9 Instrument Name: CTD Sea-Bird 9 Instrument Short Name:CTD SBE 9 Instrument Description: The Sea-Bird SBE 9 is a type of CTD instrument package. The SBE 9 is the Underwater Unit and is most often combined with the SBE 11 Deck Unit (for real-time readout using conductive wire) when deployed from a research vessel. The combination of the SBE 9 and SBE 11 is called a SBE 911. The SBE 9 uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 and SBE 4). The SBE 9 CTD can be configured with auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorometer, altimeter, etc.). Note that in most cases, it is more accurate to specify SBE 911 than SBE 9 since it is likely a SBE 11 deck unit was used. more information from Sea-Bird Electronics Community Standard Description: http://vocab.nerc.ac.uk/collection/L05/current/130/
