MCR LTER: Coral Reef: pH Time Series from Bottom-mounted SeaFET on the Fringing Reef, January-February 2011

Bottom-mounted instrumentation (SeaFET, Seabird thermistors) sampled for 6 weeks on the
fringing reef of Moorea Island, French Polynesia at site LTER Fringe 1. Sampling began in
January 2011. The instruments were secured to a cement piling at 3.3 meters depth and 0.7
meters above the sandy bottom. The SeaFET recorded voltages from a thermistor and pH
electrodes at a 10-minute sampling interval. Discrete seawater samples were collected using
a Niskin bottle during the deployment; pH, salinity, and total alkalinity of this sample
were measured to calculate seawater pH (total scale) from raw SeaFET data as well as other
carbonate chemistry parameters. The Seabird thermistors provided measures of seawater
temperature at 10-minute sampling intervals. These data are published in
Rivest, E.B. and G.E. Hofmann. 2014. Responses of the metabolism of the larvae of Pocillopora damicornis to ocean acidification and warming. PLoS ONE DOI:10.1371/journal.pone.0096172
