attribute NC_GLOBAL cdm_data_type String Point
attribute NC_GLOBAL comment String Comparisons between data recorded by gliders and discrete water samples taken at glider deployments and recoveries. Water samples were collected via Niskin bottles mounted on a CTD-rosette, or via individual Niskin bottle casts and preserved with saturated mercuric chloride until analysis. pH (on the Total pH scale) of water samples was measured spectrophotometrically at 25°C with purified meta-cresol purple (mCP, Liu et al. 2011) using 10 cm pathlength cylindrical glass cells and an Agilent Technologies Cary 8454 UV-Vis spectrometer. pH was calculated according to the equations presented in Douglas and Byrne (2017). Total alkalinity (TA) open-cell titrations for water samples were performed by a custom-built titration apparatus, following the approach of Standard Operating Procedure 3b (Dickson et al. 2007). DIC was quantified using a non-dispersive infrared method (Chen et al., 2015; Huang et al., 2012). TA and DIC accuracies were determined using Certified Reference Materials (CRMs) from Andrew Dickson’s group at the Scripps Institution of Oceanography. Measured pH was corrected for in-situ temperature, pressure and salinity using the PyCO2SYS python package.
