Observed survival of coral fragments throughout a 93-day ocean acidification and warming experiment

Abstract:

This dataset includes the observed survival of four species of Caribbean reef-building corals (Siderastrea siderea, Pseudodiploria strigosa, Porites astreoides, and Undaria tenuifolia) throughout a 93-day ocean acidification (280-3200 μatm) and warming (28°C and 31°C) experiment. Survival was assessed every 30 days during the experiment. After the experiment, these data were analysed to evaluate the effects of ocean acidification and warming on the survivorship of the four corals species.

Description

Methods & Sampling

Coral colonies were collected from inshore reefs (Port Honduras Marine Reserve; 16°11'23.5314”N, 88°34'21.9360”W) and from offshore reefs (Sapodilla Cayes Marine Reserve; 16°07'00.0114”N, 88°15'41.1834”W) along the Belize Mesoamerican Barrier Reef System (MBRS) in June 2015. The experiment was carried out from September 2015-December 2015 (recovery and acclimation June 2015-September 2015).

Coral fragments were considered dead when no living tissue remained and were quantified at each 30-day interval.

Data were analyzed using the survival package (2.39-5) and coxme package (2.2-5) in R (3.3.2).
