Nutrient and water chemistry data of Aua Reef in American Samoa from samples collected along a water quality gradient between 2022-09-13 to 2022-09-23

Description

The data described here are from water samples collected during NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD) led fly-in Mission to Aua, American Samoa from September 8-29, 2022. Five seawater samples were collected at each site, with a total of 18 sites established across a locally known water quality gradient. The seawater samples were processed in the field, then sent to the University of Hawaii at Manoa's SOEST S-Lab to be analyzed for water chemistry and nutrients. This water quality and chemistry data includes chlorophyll-a, dissolved nitrogen, nitrate, nitrite ammonia, dissolved phosphorus, phosphate, silicate, total suspended solids, and seawater pH. The analysis of water samples was one of several surveys conducted at the same sites across Aua reef in September 2022. Other surveys are described separately and accessible under 'Related Items' and include surveys of coral demography, benthic imagery/benthic cover, CTD casts, non-coral communities, and coral demography. The project was funded by NOAA CRCP under project number 31303. Samples were collected by NOAA divers Bernardo Vargas-Angel, Joy Smith, and Juliette Verstaen.
