Shallow Water Conductivity-Temperature-Depth (CTD) Profiles of Aua Reef along a water quality gradient in American Samoa from 2022-09-13 to 2022-09-23 (NCEI Accession 0278377)
The data described here is from near-shore shallow water Conductivity-Temperature-Depth (CTD) casts conducted in Aua Reef, American Samoa, by scientists of the Ecosystem Sciences Division (ESD) of the NOAA Pacific Islands Fisheries Science Center (PIFSC). The NOAA Fisheries, Ecosystem Sciences Division established 18 survey sites along the water quality gradient near land-based source pollution. This is part of a larger collection of datasets collected as part of the CRCP-funded project 'Linking watershed management activities to reef health in American Samoa' (project no. 31303).
The CTD casts provide vertical profiles (5-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 cast was conducted by snorkel. The CTD soaked at 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 5 m.
