MCR LTER: Coral Reef: Sensor Network: Bottom-mounted CTD Data - GUMPR

Physical oceanographic data from bottom-mounted instrumentation (Seabird 16+ CTD) are sampled year-round on Gump reef in Cooks Bay on Moorea, French Polynesia (GUMPR site). Sampling began in 2006 and is ongoing. The CTD measures conductivity, temperature, pressure, from which density and salinity are calculated. Data are collected every 5 minutes, processed and reported every 20 minutes. The instrument is mounted 2 m above the bottom in 6 m of depth. These data stream near real-time as part of the Digital Moorea project. Daily, weekly, monthly and yearly means are calculated for temperature, salinity, and density.
