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.
The focal point of this project was to establish a comprehensive biological, water quality, and carbonate chemistry baseline for Aua reef. This work aims at identifying measurable spatial differences in the structure and composition of the benthic and coral community at Aua that can be explained by measurable spatial patterns of water quality (nutrients and sediments) and water carbonate chemistry (pH and Alkalinity). This work is of fundamental importance for the development of the Aua Watershed Management Plan, and will enable Federal and jurisdictional resource managers to more effectively assess the effectiveness of watershed management actions reducing land-based pollution and impacts to the adjacent coral reef ecosystems.

This project builds on prior baseline and status and trends assessments conducted in 2012, 2015, and 2020 in Faga'alu Bay (U.S. Task Force watershed priority site) and Vatia (Territorial priority watershed) to address National and Jurisdictional goals to reduce land-based sources of pollution impacts in coral reef ecosystems.
This baseline assessment for land-based sources of pollution on Aua reef is part of a larger CRCP-funded project ID 31303: "Linking watershed management activities to reef health in American Samoa".
Water samples were collected alongside the CTD casts as part of this baseline assessment for the analysis of particulate and dissolved nutrients, total suspended solids, chlorophyll-a, and seawater pH and Alkalinity. Coral demographic, benthic cover, and non-coral community data was also collected as part of this project. These data are documented and archived separately.

Completeness Report
Obviously erroneous data have been removed from the final dataset. Missing values are indicated with a blank.
Conceptual Consistency
The same methods of data collection are used each time a CTD cast is conducted. Conductivity, temperature, pressure, depth, salinity, and density are routinely included in the observation dataset.
Following a 1 minute soak, CTDs are usually deployed 5-10 feet above the reef at depths ranging from 0-5 m at 18 sites along the water quality gradient in Aua, American Samoa established by the NOAA Fisheries, Ecosystem Sciences Division.
Sites were selected randomly along a water quality gradient established by local knowledge.
RBRconcerto3 CTD casts were manually collected via a snorkeler. The CTD was held just under the surface (~1m) for 1 minute to cycle water through the instrument and tubing. Afterwards, the CTD was slowly swam down to the reef benthos by the snorkeler. CTD was set in profiler mode and the descent rate was ~0.5 to 0.75 meters per second) to a depth right above the reef (maximum depth of 5m). Once the target depth is reached, the CTD is immediately pulled back on board. A GPS waypoint is taken at the beginning of the cast to mark the position and time.
