Dataset Overview | National Centers for Environmental Information (NCEI)

Dissolved inorganic carbon, total alkalinity, pH, and other variables collected from surface discrete observations onboard R/V Joe Ferguson in the U.S. East Coast near Gray's Reef National Marine Sanctuary for 2012-02-02 (NCEI Accession 0185764)

Preview graphic

This dataset contains discrete bottle sample data collected from the Gray's Reef mooring, within the Gray's Reef National Marine Sanctuary in February. Samples were collected from the surface layer, treated with 0.1 µL of HgCl2, stored on ice, and transported to the University of Delaware for DIC and TAlk analysis. Data is used to calculate pCO2 and compared to moored observations for internal consistency and validation of time series observations.

Samples for DIC, TA and pH were collected without bubbling into 125-ml groundglass bottles with greased stoppers. Bottles were overflowed 2.5 times the volume before the sample was collected and preserved with 0.1 ml of saturated mercuric chloride solution, and immediately cooled. Samples were generally stored for about a week before analysis. DIC was measured first from each sample bottle, followed sequentially by pH and TA. DIC of unfiltered water was determined using an automated analyzer built by Apollo SciTech.
