attribute NC_GLOBAL acquisition_description String Sediment cores were collected by divers, sealed in the field with rubber\nstoppers and returned to the lab for processing. Pore waters were collected by\ninserting rhizon samplers (Seeberg-Elverfeldt et al., 2005) through pre-\ndrilled holes in the core tubes. Samples were collected in gas-tight glass\nsyringes and filtered through 0.45 \\u00b5m nylon filters into storage vials.\nAlkalinity samples were titrated within 12hr of collection; other samples were\nreturned to the lab for analysis, using techniques routinely used in my lab:\nalkalinity and initial pH - Hu and Burdige (2008); sulfate, DIC, ammonium and\nDOC - Burdige and Komada (2011), Komada et al. (2016); sulfide - Cline (1969),\nAbdulla et al. (in prep.).\n \nAlkalinity and initial pH were determined by Gran Titration using a Metrohm\nautomatic titrator (model 785 DMP Titrino) combined with a Cole-Parmer pH\nelectrode, calibrated using pH 4.00, 7.00 and 10.00 NIST-traceable buffers (Hu\nand Burdige, 2008).\\u00a0 Sulfate was determined by ion chromatography and\nconductivity detection with a Thermo-Fisher Dionex ICS-5000 ion chromatograph,\nwhile DOC was determined by high-temperature combustion using a Shimadzu TOC-V\ntotal carbon analyzer (Burdige and Komada, 2011; Komada et al. 2016).\\u00a0\nAmmonium and DIC were determined by FIA analysis using a home-built system\nconsisting of a Rainin Rabbit peristaltic pump and a Dionex CDM-II\nconductivity detector (Hall and Aller, 1992; Lustwerk and Burdige,\n1995).\\u00a0 Total dissolved sulfide was determined spectrophotometrically\nwith an Ocean Optics USB400 UV-Vis spectrophotometer (Cline, 1969; Abdulla et\nal., in prep.); Total dissolved iron was also determined\nspectrophotometrically by the ferrozine method using the same\nspectrophotometer\\u00a0 (Viollier et al., 2000).\n \nNote:\\u00a0\\\"ns\\\" stands for \\\"samples not collected for this analysis\\\".

attribute NC_GLOBAL instruments_1_description String Ion chromatography is a form of liquid chromatography that measures concentrations of ionic species by separating them based on their interaction with a resin. Ionic species separate differently depending on species type and size. Ion chromatographs are able to measure concentrations of major anions, such as fluoride, chloride, nitrate, nitrite, and sulfate, as well as major cations such as lithium, sodium, ammonium, potassium, calcium, and magnesium in the parts-per-billion (ppb) range.

attribute NC_GLOBAL projects_0_acronym String Seagrass Blue Carbon
attribute NC_GLOBAL projects_0_description String NSF abstract:\nThis research will develop a quantitative understanding of the factors controlling carbon cycling in seagrass meadows that will improve our ability to quantify their potential as blue carbon sinks and predict their future response to climate change, including sea level rise, ocean warming and ocean acidification. This project will advance a new generation of bio-optical-geochemical models and tools (ECHOES) that have the potential to be transform our ability to measure and predict carbon dynamics in shallow water systems.\nThis study will utilize cutting-edge methods for evaluating oxygen and carbon exchange (Eulerian and eddy covariance techniques) combined with biomass, sedimentary, and water column measurements to develop and test numerical models that can be scaled up to quantify the dynamics of carbon cycling and sequestration in seagrass meadows in temperate and tropical environments of the West Atlantic continental margin that encompass both siliciclastic and carbonate sediments. The comparative analysis across latitudinal and geochemical gradients will address the relative contributions of different species and geochemical processes to better constrain the role of seagrass carbon sequestration to global biogeochemical cycles. Specifically the research will quantify: (i) the relationship between C stocks and standing biomass for different species with different life histories and structural complexity, (ii) the influence of above- and below-ground metabolism on carbon exchange, and (iii) the influence of sediment type (siliciclastic vs. carbonate) on Blue Carbon storage. Seagrass biomass, growth rates, carbon content and isotope composition (above- and below-ground), organic carbon deposition and export will be measured. Sedimentation rates and isotopic composition of PIC, POC, and iron sulfide precipitates, as well as porewater concentrations of dissolved sulfide, CO2, alkalinity and salinity will be determined in order to develop a bio-optical-geochemical model that will predict the impact of seagrass metabolism on sediment geochemical processes that control carbon cycling in shallow waters. Model predictions will be validated against direct measurements of DIC and O2 exchange in seagrass meadows, enabling us to scale-up the density-dependent processes to predict the impacts of seagrass distribution and density on carbon cycling and sequestration across the submarine landscape.\nStatus, as of 09 June 2016: This project has been recommended for funding by NSF's Division of Ocean Sciences.
