Growth metrics of Pocillopora verrucosa and Acropora hyacinthus corals under two pCO2 treatments at Moorea, French Polynesia from May to June of 2014 (OA coral adaptation project)

Abstract:

These data include net calcification rates and measures of horizontal and vertical colony growth of coral species Pocillopora verrucosa and Acropora hyacinthus from an experiment performed in Moorea from May to June of 2014.

Description

These data were utilized in Evensen & Edmunds, 2016.

Other datasets utilized in Evensen and Edmunds, 2016:
* Field data - coral colony interactions - https://www.bco-dmo.org/dataset/68452
* seawater chemistry - https://www.bco-dmo.org/dataset/684541

Methods & Sampling

Aggregates of 12 colonies were placed in one of six tanks (1 aggregate per tank) at either ambient (~400 uatm) or high (~1100 uatm) pCO2 (3 tanks per treatment) for 28 days. Buoyant weights of the corals were recorded before and after incubation. The difference between the initial and final buoyant weight was converted to dry skeletal weight using the aragonite density of 2.93 g cm-3, in accordance with the mineral form of CaCO3 deposited by Pocillopora and Acropora. Rates of net calcification (Gn) were normalized to the tissue area, which was estimated using wax dipping (Stimson and Kinzie 1991).

Flume experiments took place at Richard B. Gump South Pacific Research Station, Moorea.

Coral collection occurred in 2014 and was conducted at ‘LTER1 and LTER2’ (~1.5 km apart; n = 40 site−1 ) on the north shore of Moorea.

Data Processing Description

Physical conditions in the flumes were analyzed with a two-way ANOVA, with pCO2 as a fixed
effect and flume a random factor nested in each treatment. Calcification, horizontal growth, and
vertical growth collectively were analyzed in multivariate framework using mixed effects
PERMANOVA, with pCO2 as a fixed, between plot effect, flume as a random factor nested in
each treatment, and arrangement as a fixed, split-plot effect in each flume.

BCO-DMO Data Manager Processing Notes:
* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions
* All values were rounded to three decimal places if more than that.
* latitude and longitude added for experiment location

Instrument Type

Generic Name: Automatic titrator

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB12/

Generic Description:

Instruments that incrementally add quantified aliquots of a reagent to a sample until the end-point of a chemical reaction is reached.

pH Sensor

Supplied Name: Orion 3-stars

Supplied Description:

pH Sensor: Orion 3-stars, Thermo Scientific, USA, mounted with a combination pH probe (Orion Ross Ultra, Thermo Scientific, USA).

Instrument Type

Generic Name: pH Sensor

Generic Description:

An instrument that measures the hydrogen ion activity in solutions.

The overall concentration of hydrogen ions is inversely related to its pH. The pH scale ranges from 0 to 14 and indicates whether acidic (more H+) or basic (less H+).
