Description
Nearshore and offshore Conductivity-Temperature-Depth (CTD) casts were collected at sites in the Hawaiian Archipelago as part of the 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 in the main Hawaiian Islands (MHI) and Northwestern Hawaiian Islands (NWHI) in 2013, 2015, 2016, 2019, 2021, and 2024. The CTD casts provide vertical profiles (downcast only) of water column conductivity, temperature, and pressure with calculated depth, salinity, and water density.
Nearshore CTD (Sea-Bird Electronics SBE19plus in 2013, 2015, and 2016; RBR Concerto 3 in 2019, 2021, and 2024) casts were collected from a small boat using a hand line and held just under the surface for 1 minute. 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. Offshore (~10-15km from land) CTD profiles were collected from the ship using a SBE19plus (2013, 2015, 2016), RBR concerto 3 (2019, 2024 NWHI), or SBE911plus (2024 MHI). Offshore casts were typically conducted to a maximum depth of ~10m, though deeper profiles (down to ~500m) were collected at some locations and years. Data processing was performed using Sea-Bird Scientific SBE or RBR Ruskin Data Processing Software and the R package "oce".
