Coral physiology data from a short-term heating experiment using samples collected from Nikko Bay and Rebotel Reef in Palau in the spring of 2018

Abstract:

Using samples collected from Nikko Bay and Rebotel Reef in Palau in the spring of 2018, this dataset examines coral physiology of two species of coral, Psammacora digitata and Pocillopora verrucosa, as part of a short-term heating experiment.

Methods & Sampling

On-land experiments were run at the Palau International Coral Reef Center (PICRC). Coral fragments from two species of coral: Psammacora digitata and Pocillopora verrucosa, were originally collected from Nikko Bay, Palau (7°14.93′N, 134°14.149′E) at 5 meters depth, and Rebotel Reef, Palau (7°32.48′N, 134° 49.34′E) at 7.5 meters depth.

Coral collection and heating experiments were run in the same fashion as detailed in the Hoadley et al. (2019) (see related reference listed below), with the following exceptions:

The experimental system was held indoors, and lighting was provided by LEDs (CREE LED XP-G3, cool white) set to diurnal intensity ramping by digital controllers (Storm X, Coralux). Corals were supplied with a continuous flow of seawater (at 1 liter per minute) with water flow in each treatment bin supplemented with a submersible powerhead pump (Sicce Micra – 90 gallons per hour). Coral skeletal surface area was calculated by 3-D scanning (HDI 120, LMI Technologies).

Data Processing Description

All sampling methods and analytical procedures used for collecting this data have been previously presented in Hoadley et al. (2019), referenced below. The one additional procedure that deviates from this is the 3-D scanning of coral skeletons that is described above.

Coral skeleton scans were converted to 3D surface area mesh maps in FlexScan 3D software (Polyga)
