Description

Mean calcification rates for the coral Porites rus and alga Hydrolithon onkodes in varying carbonate chemistry conditions. These data are part of a larger data set containing light and dark calcification rates and experimental chemistry conditions, which in turn are part of experiments performed during July-August 2011 in French Polynesia to test the effect of various concentrations of carbonate and bicarbonate ions on the calcification of a coral and a calcifying alga.

Methods & Sampling

For calculating mean calcification rates, buoyant weight (± 1 mg) was recorded before and after the 15 d of incubation, and the difference between the two was converted to dry weight using an aragonite density of 2.93 g cm^-3 for Porites rus, and a calcite density of 2.71 g cm^-3 for Hydrolithon onkodes. Calcification was normalized to surface area estimated using aluminum foil for P. rus, and by digital photography and image analysis (Image J, US NIH) for H. onkodes.

Data Processing Description

BCO-DMO Processing Notes:

Original data file: “Raw_data_Comeau_et_al_PRSB-1.xls” contained three spreadsheets. This file was split into three separate datasets. Resultant datasets were edited in excel by BCODMO. The following edits were made to the file mean_calcification.dat:

-Added BCO-DMO header
    -edited 'Porites run calcification' to 'calcification_Porites_rus'
    -edited 'Hydrolithon onkodes calcification' to 'calcification_Hydrolithon_onkodes'
    -replaced spaces in condition text with underscores
-Added column for 'date_begin' and 'date_end'
-Added 'lat' and 'lon' column of experiment site (Richard B. Gump Research Site, Moorea, Tahiti)
-Added title, version and PI lines

-Added column for deployment ID 'deploy_id' with "lab_Carpenter_Moorea" as a value.
