MCR LTER: Coral Reef: Ocean Currents and Biogeochemistry: salinity, temperature and current at CTD and ADCP mooring FOR01 from 2004 ongoing

Moored and bottom-mounted instrumentation (ADCP, CTD, thermistors, wave-tide meters) sampled year-round on the reef of Moorea Island, French Polynesia at LTER 1 fore reef site (FOR01). Sampling began in 2005. All data have been interpolated onto a 20 min grid. ADCP data are organized into 1-meter bins, measured as height from the bottom, to a maximum of 20 bins. All bins may not be filled, and although post-processing attempted to exclude data from bins 'above the surface', users need to exercise caution with the near-surface bins. CTD parameters include Pressure, Temperature, Conductivity, Salinity, and Density. The two moored CTD packages are located approximately 5 and 14 meters above the bottom and there are up to 5 additional temperature thermistors spaced vertically along the mooring line. Note that the upper CTD and temperature thermistor data were terminated in 2020, and the bottom CTD was terminated in February 2022. There are 2 bottom mounted thermistors in the vicinity of the mooring at 10 and 20 meter depth. A bottom-mounted wave-tide meter at 10-meter depth provides a measure of significant wave height and dominant wave period at a 2-hour sampling interval. Tide-related data may be calculated from bottom-mounted pressure sensor data.
