        abstract:  NCEI Accession 0157461 includes Surface underway, chemical, discrete sample, meteorological, physical and profile data collected from PELICAN in the Coastal Waters of Louisiana, Coastal Waters of Texas and Gulf of Mexico from 2013-09-09 to 2013-09-22. These data include BAROMETRIC PRESSURE, CONDUCTIVITY, DISSOLVED INORGANIC CARBON (DIC), Partial pressure (or fugacity) of carbon dioxide - atmosphere, Partial pressure (or fugacity) of carbon dioxide - water, SALINITY, TOTAL ALKALINITY (TA), WATER TEMPERATURE and pH. The instruments used to collect these data include Alkalinity titrator, CTD, Carbon dioxide (CO2) gas analyzer, Non-dispersive infrared (NDIR) dissolved inorganic carbon (DIC) analyzer, Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement, bottle and pH sensors. These data were collected by Antonio Mannino of US NASA; Goddard Space Flight Center and Dr. Joseph Salisbury and Christopher Hunt of University of New Hampshire as part of the Coastal_GOMEX2013_BOT and Coastal_GOMEX2013_UW data set. CDIAC associated the following cruise ID(s) with this data set: 32PE20130909 and GOMEX2013 The Global Coastal Carbon Data Project data includes the bottle (discrete) and surface (underway) carbon-related measurements from coastal research cruises, the data from time series cruises and coastal moorings. The coastal regions data are very important for the understanding of carbon cycle on the continental margins.
        purpose:  This dataset is available to the public for a wide variety of uses including scientific research and analysis.

                description:  Parameter or Variable: Dissolved Inorganic Carbon; Abbreviation: DIC; Observation type: discrete; In-situ / Manipulation / Response variable: In-situ observation; Measured or calculated: Calculated; Detailed sampling and analyzing information: DIC of unfiltered water was determined using an automated analyzer built by Apollo SciTech (Bogart, GA). Immediately after opening the sample bottle, a digital syringe withdrew a small amount of sample (0.5 mL), acidified it with 10 % phosphoric acid and subsequently measured the evolved CO2 with a Li-Cor 6262 non-dispersive infrared gas analyzer (similar to the method described by Cai and Wang 1998).; Standardization description: Certified seawater reference materials from Dr. A. Dickson were used to determine DIC concentration by preparing a calibration curve covering the range of DIC from 200 to 2000 μmol kg−1 (Dickson et al. 2003), with a resulting precision ranging from 0.05 to 0.5 % (or 0.1–10 μmol kg−1), with an average of ∼0.1 % (2 μmol kg−1).; CRM batch number: 131 136.

                description:  Parameter or Variable: Total alkalinity; Abbreviation: TA; Observation type: discrete; In-situ / Manipulation / Response variable: In-situ observation; Measured or calculated: Measured; Type of titration: Gran; Cell type (open or closed): open; Curve fitting method: AT and pH of unfiltered water were simultaneously measured by the same instrument (Apollo SciTech AS-2), and thus pH and AT measurements are both based on the same pH electrode. The pH electrode used in the AT titration (Orion 3-Star, Thermo Fisher Inc.) was calibrated using three low ionic strength pH buffers certified on the U.S. National Bureau of Standards (NBS) scale to ±0.01, and the initial reading before the addition of acid titrant was taken as the sample pHNBS (pH on the NBS scale, hereafter simply referred to as pH). AT was measured by Gran titration (Gran 1952) with 0.1 N HCl using an automated titrator. This method adds an initial aliquot of acid to the sample in an open cell, generally lowering the sample pHNBS below 3, and then adds subsequent aliquots of titrant until the pHNBS changes linearly with the volume of acid added. The AT endpoint is then obtained from linear regression of the change of pHNBS against the volume of acid added, according to a Gran transformation.; Uncertainty: Multiple analyses of the Dickson reference material resulted in a calculated precision of this method of about 0.1 % (or ∼±2 μmol kg−1). The accuracy of the AT automated system, also calibrated with multiple batches of the Dickson CRM as discussed above, was ±3–4 μmol kg−1; Method reference: DOE (U.S. Department of Energy). 1994.

            type:  Carbon dioxide (CO2) gas analyzer
            description:  Carbon dioxide gas analyzer has often been referred to as LI-COR, because a lot of researchers choose to use products manufactured by LI-COR incorporation for their carbon dioxide measurement. The main component of a carbon dioxide analyzer is a nondispersive infrared (NDIR) spectroscopic sensors to detect CO2 in a gaseous environment by its characteristic absorption. Carbon dioxide (CO2) gas analyzer works together with carbon dioxide (CO2) equilibrator (insttypes_id 184) to measure carbon dioxide in the water. To measure water carbon dioxide, water needs to be continuously supplied to a showerhead inside an equilibrator. As the water flows through the equilibrator chamber, dissolved carbon dioxide exchanges quickly with air in the headspace. This air is then sampled by the carbon dioxide analyzer to determine the mole fraction of CO2 in water.

            type:  Non-dispersive infrared (NDIR) dissolved inorganic carbon (DIC) analyzer
            description:  A known amount of seawater is dispensed into a stripping chamber where it is acidified and purged with an inert gas. The amount of CO2 in the resulting gas stream is determined with a non-dispersive infrared (NDIR) carbon dioxide analyzer.

                code:  Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement
            type:  Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement
            description:  A carbon dioxide equilibrator is usually in the shape of a vertical tube, with a shower head on the top, some head space, a lot of beads to increase the surface exchange area between water and air, a water seal device at the bottom to allow water to overflow, but prevents air exchange between inside and outside. Carbon dioxide (CO2) equilibrator works together with carbon dioxide (CO2) gas analyzer (insttypes_id 183) to measure carbon dioxide in the water. To measure water carbon dioxide, water needs to be continuously supplied to a showerhead inside an equilibrator. As the water flows through the equilibrator chamber, dissolved carbon dioxide exchanges quickly with air in the headspace. This air is then sampled by the carbon dioxide analyzer to determine the mole fraction of CO2 in water.
