Abstract:

Carbonate chemistry data from experiments conducted as part of a study of the effects of irradiance on the response of the coral Acropora pulchra and the calcifying alga Hydrolithon reinboldii to temperature elevation and ocean acidification published in Comeau et al. (2014).

Methods & Sampling

pH was measured twice daily using a portable pH meter (Orion 3-stars) with a DG 115-SC pH probe (Mettler). AT titrations were performed on the day of seawater collection using open cell potentiometric titration with an automatic titrator (T50, Mettler-Toledo), and AT calculated after Dickson et al. (2007). Parameters of the carbonate system were calculated from salinity, temperature, AT, and pHT using the R package seacarb (Lavigne and Gattuso, 2012).

For more details see Comeau et al.(2014).

Data Processing Description

R packages:

Lavigne, H., Gattuso, J.-P., 2012. seacarb: seawater carbonate chemistry with R, R package version 2.4.6, http://CRAN.Rproject.org/package=seacarb.

BCO-DMO Data Manager Processing Notes:
* Data submitted as sheet "carbonate chemistry" in original excel file "Comeau_et_al_JEMBE_2014.xlsx" exported as csv with the formatting that was set in Excel.
* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions: only A-Za-z0-9 and underscore allowed. Can not start with a number. (spaces, +, and - changed to underscores).

Supplied Description:

pH: Orion 3-stars pH Meter fitted with a DG 115-SC pH probe

Instrument Type

Generic Name: pH Sensor

Generic Description:

An instrument that measures the hydrogen ion activity in solutions.

The overall concentration of hydrogen ions is inversely related to its pH. The pH scale ranges from 0 to 14 and indicates whether acidic (more H+) or basic (less H+).

Supplied Description:

Instrument Type

Generic Name: Salinity Sensor

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/350/

Generic Description:

Category of instrument that simultaneously measures electrical conductivity and temperature in the water column to provide temperature and salinity data.

Supplied Name: ThermoFisher Traceable

Supplied Description:

Instrument Type

Generic Name: Water Temperature Sensor

Acronym: Water Temp Sensor

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/134/

Generic Description:

General term for an instrument that measures the temperature of the water with which it is in contact (thermometer).
