Particulate Carbon Concentrations and Stable Carbon Isotopes Dataset Description: Methods and Sampling: <p>Dual-flowpath <em>in situ</em> pumps (McLane WTS-6-1-142LVUP) were deployed at targeted depths for 3-5 hours at 4 stations (CR1, CR2, CR3 and CR5), with approximately 1400 L seawater flowing through the filters. The filter holders had two stages for two size fractions and multiple baffle systems designed to ensure even particle distribution and prevent particle loss (Bishop et al. 2012; Lam et al. 2018).</p>
<p>Samples analyzed in this study were collected on the filter holder/flowpath which was loaded with a 51 um Sefar polyester mesh prefilter followed by a paired 0.5 um Glass Fiber Filter (GF/F) (Advantec GC-50, LOT No. 70207718, 142 mm diameter). The 51 um prefilter was underlain by a 150 um Sefar polyester mesh support filter to facilitate filter handling. The GF/F filters were pre-combusted at 450 C&nbsp;overnight to remove any potential organic matter. In this dataset, data reported from the 51 um prefilter were referred to as “LSF” to indicate large size fraction (&gt; 51 um); data reported from the main filters (GF/F, 0.5 – 51 um) were referred to as “SSF” to indicate small size fraction. Upon recovery of the pumps, the 51 um prefilters were subsampled into slices of 1/4 or 1/2 of the total filter, and the LSF particles were rinsed onto 26 mm diameter Glass Fiber Filters. The LSF and SSF GF/Fs were then dried at room temperature for 24 h. At CR, 1/4 of each LSF and SSF filter was used for Particulate Inorganic Carbon (PIC) concentration and d<sup>13</sup>C measurements; 1/4 of each LSF and a circle of 26 mm diameter of the SSF was used for Total Carbon (TC) concentration and d<sup>13</sup>C measurements.</p>
<p>For each pump cast, a dipped blank sample was collected, and all concentration calculations were corrected by subtracting the dipped blank signal to remove the potential effect of DOC absorbed onto the filters. The effect of DOC on the isotopic values of filter TC is neglected because the amount of DOC is trivial compared to POC on the filters.</p>

Collaborative Research: New approaches to study calcium carbonate dissolution on the sea floor and its impact on paleo-proxy interpretations

Collaborative Research: New approaches to study calcium carbonate dissolution on the sea floor and its impact on paleo-proxy interpretations
<p><em>NSF Award Abstract:</em><br />
The uptake of anthropogenic CO2 by the ocean will eventually be mitigated by the dissolution of CaCO3 on the sea floor. Dissolution is an important component of the carbon cycle in models used for climate projections though the relative importance of where it occurs (water column versus sediments) and the rates and processes involved are not fully understood. This ambitious field and laboratory study is designed to advance our knowledge of the important factors that control carbonate dissolution/ preservation in deep ocean sediments. Using a novel tracer approach and multiple in situ sampling strategies, the project will investigate sea floor dissolution rates, their kinetic controlling factors, the depth in sediments at which dissolution occurs, the role that oxidation of particulate organic carbon plays, and the ramifications of solid phase alteration for the use of geochemically-based paleoceanographic proxies. The project will foster further development of benthic lander technology and yield key information relating sea floor conditions to carbonate dissolution rate, thereby helping to constrain the rate at which the ocean can neutralize the impacts of ocean acidification. Graduate and undergraduate students will be trained and the research team will use film and animation to bring this work to a broader audience through a collaboration with the Los Angeles Natural History Museum.</p>
<p>The research team has developed a new approach to quantify calcium carbonate dissolution rates based on 13-C labeled carbonate substrates, a technique which is significantly more sensitive than traditional approaches based on alkalinity and/or calcium measurements. This has opened a range of new opportunities and insights into the governing mechanisms and rates of calcium carbonate dissolution, a challenging and long-standing geochemical problem. Carbonate dissolution rates on the sea floor will be directly assessed by benthic chamber flux measurements of alkalinity and calcium as well as pore water models of TCO2 and alkalinity and their isotopic composition. The potential impacts of organic carbon remineralization will be measured through oxygen and nutrient flux determinations, pore water gradients and modeling. Labeled 13C-enriched calcite will serve as a tracer of near surface dissolution processes when added to benthic chambers and of down-core dissolution processes using 13C-labeled rods inserted into the sediment column. These in situ experiments of labeled carbonate dissolution will be the first of their kind. To complement these measurements, the team will continue development of a rhizon-based pore water sampler that works on a multi-corer at all ocean depths. Field experiments will be conducted at sea at 4-6 sites in a transect through water column supersaturation to undersaturation between Panama and the Galapagos. Dissolution rate measurements, coupled with analyses of cation/Ca ratios in CaCO3 foraminiferal shells will help calibrate the impact of dissolution on paleo-proxy interpretations. Further, analyses of sediment calcite and aragonite fractions will help explain net dissolution and sediment response with time. The results from this study should help to better parameterize sediment variables in ocean-climate models (GCMs), which has important implications for predicting the consequences of ocean acidification and the modeling of paleoceanographic records. The methodologies and new techniques will surely be adopted by other researchers, therefore impacting the larger geochemical community.</p>
<p>This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.</p>
