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.\nOxygen profiles in the cores were collected with polarographic microelectrodes\n(Luther et al., 2008) using a DLK 70 WebPstat electrochemical analyzer (AIS,\nInc.) and a computer-controlled micro-profiler.\n \nNote: 'sd' in this dataset means that the electrode signal deterioriated,\nlikely due to sulfide interference.

attribute NC_GLOBAL instruments_0_dataset_instrument_nid String 746005
attribute NC_GLOBAL instruments_0_description String A miniaturized Clark-type dissolved oxygen instrument, including glass micro-sensors with minute tips (diameters ranging from 1 to 800 um). A gold or platinum sensing cathode is polarized against an internal reference and, driven by external partial pressure, oxygen from the environment penetrates through the sensor tip membrane and is reduced at the sensing cathode surface. A picoammeter converts the resulting reduction current to a signal. The size of the signal generated by the electrode is proportional to the flux of oxygen molecules to the cathode.The sensor also includes a polarized guard cathode, which scavenges oxygen in the electrolyte, thus minimizing zero-current and pre-polarization time.With the addition of a meter and a sample chamber, the respiration of a small specimen can be measured.  Example: Strathkelvin Inst. http://www.strathkelvin.com

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.
