Description

The effect of light and PCO2 on the calcification and survival of Pocillopora damicornis recruits settled from larvae
released in southern Taiwan was tested.

These data include the weight measurements for each light treatment in each of the tanks over the duration of the experiment. Growth rate is calculated.

These data were published in Aaron M Dufault, Aaron Ninokawa, Lorenzo Bramanti, Vivian R Cumbo, Tung-Yung Fan, Peter J Edmunds (2013) The role of light in mediating the effects of ocean acidification on coral calcification. Journal of Experimental Biology 216: 1570-1577. doi:10.1242/jeb.080549

Methods & Sampling

Dataset acquisition description

In March 2011and June 2012, recruits were incubated at 31, 41, 70, 122 and 226 µmol photons m-2 s-1 under ambient (493 µatm) and high PCO2 (878 µatm). After 5 days, calcification was measured gravimetrically and survivorship estimated as the number of living recruits.

To measure calcification, recruits were cleaned of tissue in bleach (6% NaOCl for 8 h), removed from the tiles with a razor blade, and weighed individually (±100 ng, UMT2 balance, Mettler-Toledo) after drying (72 h at 27°C); calcification was normalized to protein and time (mg CaCO3/mg protein/day).

Dataset Processing Description

BCO-DMO processing notes:

- added conventional header with dataset name, PI name, version date, reference information
- added lab, lat, lon, expt columns
- renamed parameters to BCO-DMO standard
- sorted by expt, treatment_pCO2, tank, treatment_light, tile, corallite_id
