This dataset contains chemical data collected on R/V Knorr during cruise KN199-04 in the North Atlantic Ocean from 2010-10-17 to 2010-11-02. These data include depth, particulate organic Carbon (POC), and particulate organic nitrogen. The instruments used to collect these data include CHN Elemental Analyzer and Pump surface. These data were collected by Charles McClain and Joaquin Chaves of National Aeronautics and Space Administration as part of the "U.S. GEOTRACES North Atlantic Transect (U.S. GEOTRACES NAT)" project and "U.S. GEOTRACES (U.S. GEOTRACES)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-05-01.

The following is the text of the dataset description provided by BCO-DMO:

Supplemental Information	Acquisition Description: Sampling Excerpt from associated file: Determination of Carbon and Nitrogen collected on Whatman glass fiber filters (GFF) Water samples are filtered through 2.5 cm pre-combusted Whatman GFF filters using an all-glass filtering funnel. Once enough material has been accumulated on the filter the samples are stored in Nalgene 1.8 mL cryovials at -80°C until analysis. For shipping, samples are stored in liquid nitrogen dry-shippers. Prior to analysis samples are thawed and dried overnight at 65°C inside the uncapped cryovials. Dry samples in the uncapped vials are transferred overnight to a desiccator saturated with HCl fumes to remove particulate inorganic carbon present in the sample. The air in the desiccator is kept saturated by leaving concentrated HCl in an open container in the lower compartment of the desiccator. Acid–treated samples are transferred back to a 65°C oven overnight, after which can be stored capped in cryovials for extended periods prior to analysis in elemental analyzer. For analysis the samples are wrapped in tin foil discs (PE N241-1363) and pelletized on a Parr Pellet press. The samples are analyzed in the Perkin Elmer CHNS/O Analyzer 2400 Series II. The manufacturer’s data management software for the elemental analyzer is set up so that the analysis report includes the zero read (ZR), and the carbon and nitrogen signals (CS, NS) from the instrument for each analyzed sample. For complete analysis and processing details, see the Supplemental Document: Determination of Carbon and Nitrogen collected on Whatman glass fiber filters (GFF) (POC_Pkn_Elmer_2400.pdf).
