National Coral Reef Monitoring Program: Shallow Water Conductivity-Temperature-Depth (CTD) Profiles for select locations across American Samoa from 2015 to 2023
The data described here result from near-shore shallow water Conductivity-Temperature-Depth (CTD) casts conducted at select sites around American Samoa as part of the ongoing National Coral Reef Monitoring Program (NCRMP). These surveys were conducted by the NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD; formerly the Coral Reef Ecosystem Division) during ESD-led NCRMP missions to American Samoa in 2015, 2018, and 2023. The CTD casts provide vertical profiles (30-m max depth, downcast only) of water column conductivity, temperature, pressure, with calculated depth, salinity, and water density.
The CTD (Sea-Bird Electronics, SBE19-plus in 2015 and 2018, RBR Concerto in 2023) was deployed from a small boat using a hand line and held just under the surface for 1 minute to cycle water through the instrument and tubing. Afterward, data were collected by lowering the CTD in profiling mode at an even pace (descent rate ~0.5 to 0.75 meters per second) to a maximum depth of 30 m. Data processing was performed using Sea-Bird Scientific SBE or RBR Ruskin Data Processing Software and the R package "oce".
