Abstract:

Partial pressure of carbon dioxide (pCO2) from in-situ flume experiments to manipulate pCO2 on shallow tropical coral reef communities at UCB Gump Research Station Moorea, French Polynesia in May of 2018. These data are for a proof of trial experiment for the Shallow COral REef Free Ocean Carbon Enrichment (SCORE FOCE), outlined in Srednick et al. (2020).

Methods & Sampling

Seawater pCO2 was calculated from TA, pH, salinity, and temperature using the R package seacarb (Lavigne and Gattuso, 2013).

Data sources used for calculations:
TA and salinity from "Srednick et al. 2020 - L&O Methods - TA_SAL" https://www.bco-dmo.org/dataset/812891
pH from "Srednick et al. 2020 - L&O Methods - pH seafet" https://www.bco-dmo.org/dataset/812864
temperature from "Srednick et al. 2020 - L&O Methods - temperature https://www.bco-dmo.org/dataset/812873 "

The full methodology can be found in Srednick et al. (2020).

Data Processing Description

Data were processed using seacarb, seawater carbonate chemistry, R package version 2. 4. 10 (Lavigne H and Gattuso, 2013).

BCO-DMO Data Manager Processing Notes:
* Original data submitted as in Excel file L&O_2019_data.xlsx sheet "pCO2" extracted to csv.
* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions (spaces, +, and - changed to underscores). Units in parentheses removed and added to Parameter Description metadata section.
* blank values in this dataset are displayed as "nd" for "no data." nd is the default missing data identifier in the BCO-DMO system.
* Added ISO_DateTime_UTC column in ISO 8601 format yyyy-mm-ddTHH:MMZ from local date and time provided in local time, Tahiti, UTC-10.
