Water chemistry data from 20 sites in Nu'uuli Pala Lagoon and Backreef, American Samoa, collected between November 8 and 20, 2024. Five seawater samples were collected per site across a known water quality gradient and analyzed for chlorophyll-a and dissolved nutrients. The data was collected by NOAA's Pacific Islands Fisheries Science Center and processed by the University of Hawaii at Manoa.
Use Cases
- Modeling water quality gradients based on chlorophyll-a and nutrient concentrations
- Assessing coral reef ecosystem health based on dissolved nutrient levels
- Correlating environmental conditions with coral demographics based on related surveys
- Monitoring coastal processes and climate change impacts on lagoon chemistry
Strengths
- Data covers 20 distinct sites across a known environmental gradient
- Each site includes five replicate seawater samples
- Includes multiple measured parameters: chlorophyll-a, dissolved nutrients, salinity, pH, and total suspended sediments
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
