National Coral Reef Monitoring Program: Shallow Water Conductivity-Temperature-Depth (CTD) Profiles for select coral reef locations across the Hawaiian Archipelago from 2013 to 2021

Metadata Updated: March 16, 2024

The data described here result from near-shore shallow water Conductivity-Temperature-Depth (CTD) casts conducted at select sites around the Hawaiian Archipelago 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 the Hawaiian Archipelago from 2013 to 2021. The CTD casts provide vertical profiles (30-m max depth, downcast only) of water column conductivity, temperature, and pressure with calculated depth, salinity, and water density. From 2013 to March 2019, a Sea-Bird Electronics, SBE19-plus instrument was used to collect this data, while in July 2019 to 2021, a RBR Concerto3 CTD was utilized.

The CTD was deployed from a small boat using a hand line and held at approximately 1-m depth for 1 minute to cycle water through the instrument and tubing (SBE19) or equilibrate the internal thermistor with ambient seawater (RBR). Afterward, data were collected by raising the CTD to just under the surface and then lowering 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 Data Processing Software, RBR Ruskin software, and the R package "oce".
