Five seawater samples were collected at each site, with a total of 20 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 dissolved nutrients and chlorophyll-a. This water quality and environmental data includes chlorophyll-a, dissolved nutrients (nitrate + nitrite, phosphate, ammonia), total suspended sediments (measured at NOAA), seawater salinity (measured at NOAA), and seawater pH (measured in the field). In addition to environmental conditions surveyed across sites in Nu'uuli Pala Lagoon and Backreef in November 2024, additional surveys are described separately and accessible under 'Related Items' and include surveys of coral demography, benthic imagery/benthic cover, subsurface temperature loggers, non-coral communities, and coral demography. The project was funded by NOAA CRCP under project number 31454, and through funds from NOAA's Pacific Islands Regional Office. Land-based sources of pollution negatively impact reef communities. Our goal here was to collect water samples and analyze them for their nutrients and environmental properties. We intend to assess whether or not a water quality gradient exists in the coral reefs of Nu'uuli Pala Lagoon and Backreef. The focal point of the mission was to establish a biological and water quality baseline for Nu'uuli Pala Lagoon and Backreef. This work was aimed at identifying measurable spatial differences in the structure and composition of the benthic and coral community at Nu'uuli Pala Lagoon and Backreef that can be explained by measurable spatial patterns of water quality (nutrients and sediments). This work 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.

Additional funds were provided by NOAA Pacific Islands Regional Office. This mission (CRCP Project number 31454) sought out to examine the impacts of LBSP on reef communities (coral and non-coral) in Nu'uuli, the largest watershed in American Samoa. This mission builds on prior assessment and monitoring surveys of benthic reef communities conducted in Faga'alu and Vatia bays in 2012 and 2015, and Aua in 2022 to address National and Jurisdictional goals to reduce the impacts of LBSP in local priority watersheds. Together with periodic monitoring, this coral reef community baseline for Nu'uuli Pala Lagoon and Backreef will allow scientists to quantify temporal changes in the condition and integrity and enable Jurisdictional and Federal resource managers to make informed decisions pertaining to the protection and preservation of critical habitats. The overall effort required to evaluate the effectiveness of management strategies is significant and requires close coordination between local and Federal efforts. For this project, NOAA and CIMAR staff worked in tandem with staff from American Samoa's Department of Marine and Wildlife Resources and the Coral Reef Advisory Group. false eng false Data Table ESD_Environmental_Parameters_DataDictionary_Nuuuli_2024 2025-09-18 publication CSV - Comma Separated Values (Text) NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact WWW:LINK-1.0-http--link NCEI Contact Information Information for contacts at NCEI. information distributor https://accession.nodc.noaa.gov/0307818 WWW:LINK-1.0-http--link ESD_Environmental_Parameters_Nuuuli_2024.csv Contains data from 20 sites along a water gradient in Nu'uuli Pala Lagoon and Backreef, American Samoa.

Missing values are indicated with a n/a. Conceptual Consistency The same methods of data collection are used each time a water sample is collected. Pressure, depth, temperature, and salinity are routinely included in the observation dataset. The data are very consistent, sample collection and processing protocols are adhered to very rigorously, both in the field and in the lab. All carbonate system collection and measurement methodologies follow the protocols accepted by the greater scientific community and outlined in Dickson et al. (2007) Sites were selected randomly along a water quality gradient established by local knowledge. Water samples collected in the field and analyzed by SOEST. Smith, Joy joy.smith@noaa.gov processor Water samples were measured for pH using hand-held YSI that had been calibrated with buffers (pH 4, 7, 10).
