Title: National Coral Reef Monitoring Program: Shallow Water Conductivity-Temperature-Depth (CTD) Profiles for selected locations across the Northwestern Hawaiian Islands from 2015-07-31 to 2015-08-19 (NCEI Accession 0161170)
Abstract: The data described here result from near-shore shallow water Conductivity-Temperature-Depth (CTD) casts conducted at selected sites around the Northwestern Hawaiian Islands 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 Northwestern Hawaiian Islands in 2015. The CTD casts provide vertical profiles (30-m max depth, downcast only) of water column conductivity, temperature, and pressure (Sea-Bird Electronics, SBE19-plus), with calculated depth, salinity, and water density. The CTD 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 Data Processing Software and the R package "oce".
