Coral community hourly metabolism from outdoor flumes at the UCB Gump Research Station Moorea, French Polynesia from November of 2015 to March of 2016

Abstract:

This dataset contains hourly coral community metabolism data from outdoor flumes at the UCB Gump Research Station Moorea, French Polynesia. These measurements were taken during an experiment designed to measure coral reef community metabolism responses to ocean acidification over a 4-month period from November 13th, 2015 to March 15th, 2016. These data were published in Carpenter et al. (2018).

Methods & Sampling

See Carpenter et al. (2018) for a detailed overview of the methodology of the experiment designed to measure coral reef community metabolism responses to ocean acidification over a 4-month period from November 13th, 2015 to March 15th, 2016 in outdoor flumes at the UCB Gump Research Station Moorea, French Polynesia.

Hourly metabolism data:
Community Gnet was measured using the alkalinity anomaly method (after Smith (1973)), and community Pnet was measured using changes in dissolved oxygen (DO). Calculated per hour.

Community composition:
~ 25% coral cover, comprised of 11% cover of massive Porites spp., 7% Porites rus, 4% Montipora spp. and 3% Pocillopora spp. There was ~ 7% cover of crustose coralline algae (CCA), with 4% Porolithon onkodes and 3% Lithophyllum kotschyanum, and ~ 5% cover of small pieces (i.e., ~ 1-cm diameter) of coral rubble (Fig. S2, Carpenter et al., 2018)."

Data Processing Description

BCO-DMO Data Manager Processing Notes:
* Data submitted as sheet "hourly metabolism" in original excel file exported as csv with the formatting that was set in Excel.
* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions
* blank values in this dataset are displayed as "nd" for "no data." nd is the default missing data identifier in the BCO-DMO system.
* Column name "Pnet N" occurred twice in the dataset. After consulting the submitter, the first occurance was changed to "Gnet_N."
