Dataset: Settling and mortality measurements of brooded coral larvae at high and ambient temperature and pCO2, Taiwan, March 2011 (MCR LTER project, Climate_Coral_Larvae project)

Survival of the two groups of 20 larvae allocated to each tank for this purpose was determined at 10:00 h each sampling day by carefully removing the tubs from each tank and inspecting the seawater for larvae. Larvae were scored as swimming, settled and metamorphosed recruits (on the plastic of the tub), or missing; missing larvae were assumed to have died and broken down. Survivorship was calculated as the number of swimming larvae on each of the four days, divided by the number of larvae initially added, less the number that settled. Settled larvae (i.e., recruits)were removed from the analysis on the day they were noted as settled because the objective of the analysis was to evaluate survivorship of the swimming larvae. Importantly, recruits did not contribute to the larvae scored as dead, but they did reduce the sample size for the assessment of survival at each sampling interval; this effect was small.

The 'ambient' and 'high' pCO2 levels: 49.4 Pa versus 86.2 Pa
The 'ambient' and 'high' temperatures: 24.00 °C [ambient] versus 30.49 °C
