Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 26, 2026 | Last Modified: 2019-12-10T00:00:00.000+00:00
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.
