NCCOS Assessment: Water Quality Data to Assess Eutrophication Effects on Coral Ecosystem Health in Vatia Bay, American Samoa from 2015-05-13 to 2018-08-28 (NCEI Accession 0208020)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 03:31 AM | Dataset Last Updated: December 10, 2019 at 12:00 AM
This dataset represents three years of water quality data collected in Vatia Bay, American Samoa. A standard suite of nutrient parameters (nitrate, nitrite, ammonium, urea, total nitrogen, orthophosphate, total phosphorus and silica), as well as tracers of human waste (sucralose and caffeine) were quantified at sixteen randomly selected sites (surface and bottom samples) monthly from 2015 to 2017. In 2018, sampling efforts focused on capturing precipitation events, so the sampling was conducted at less regular intervals.
