Bottle sample TA, pH, and DIC collected during an inter-comparison of autonomous in situ instruments for ocean CO2 measurements under laboratory-controlled conditions at Scripps Institution of Oceanography in 2016

Abstract:

This dataset contains total alkalinity (TA), pH, and dissolved inorganic carbon (DIC) from bottle samples collected 3 to 4 times a day. These data were part of an inter-comparison of autonomous in situ instruments for ocean CO2 measurements under laboratory-controlled conditions at Scripps Institution of Oceanography in August of 2016. These data were published in Shangguan et al. (2022).

Methods & Sampling

Bottle samples are analyzed following descriptions:
The pH samples were analyzed by spectrophotometry immediately after collection using purified mCP. The AT and DIC samples were poisoned and stored following standard protocol (Dickson et al., 2007), and were analyzed within three days using CRMs for quality assurance (Batch 156; see Dickson et al., 2003). AT was determined by open-cell potentiometric titration (Gran, 1952) and a nonlinear least squares approach (Dickson et al., 2007). DIC was determined by acidifying samples and quantifying the extracted CO2 gas by infrared detection (Goyet and Snover, 1993).

Data Processing Description

Data is output directly from instrumentation.

BCO-DMO Data Manager Processing Notes:
* Data from source file "2016 bottle samples.xlsx" Sheet1 were imported into the BCO-DMO data system. Value "na" in the source file was classified as a missing data identifier.
* Parameters (column names) renamed to comply with BCO-DMO naming conventions. See https://www.bco-dmo.org/page/bco-dmo-data-processing-conventions
