Shallow Water Conductivity-Temperature-Depth (CTD) Profiles along a water quality gradient in Aua, American Samoa from 2022-09-13 to 2022-09-23

This metadata record describes the data collected 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) from September 13 - 23, 2022. For this fly-in mission (MP2206), 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 #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.
