As part of the Northeast Coastal and Barrier Network's Estuarine Nutrient Enrichment Monitoring program, Network staff continued to estuarine water quality at several park units. This file contains spatial (i.e., not continuous) water quality data collected through the most recent field season at Assateague Island National Seashore.

The manuscript assembled data from existing sources (summarized below) to assess water quality improvements in three estuaries (Peconic Estuary (NY), Roberts Bay (FL), and Newport Bay (CA) associated with reduction of nonpoint sources of nutrients. No EPA generated data in this manuscript, only secondary sources. This dataset is associated with the following publication: Green, L., C. Magel, and C.A. Brown. Management pathways for the successful reduction of nonpoint source nutrients in coastal ecosystems. Regional Studies in Marine Science. Elsevier B.V., Amsterdam, NETHERLANDS, 45: 101851, (2021).

This data release consists of the data used to develop SPAtially Referenced Regression On Watershed(SPARROW) attributes models for estimating loads of total phosphorus and total nitrogen in Tennessee streams. These data support the publication containing the Tennessee SPARROW models results (Hoos and others, 2019) and include model input used in the South Atlantic-Gulf Drainages and Tennessee River Basin (SAGT) nutrient SPARROW models (Hoos and McMahon, 2009; Garcia and others, 2011) as well as model input for river basins in Tennessee not included in the domain of the published SAGT SPARROW models. Also included in this data release are model coefficients, the software required to execute the Tennessee SPARROW models, and the model output for all streams in Tennessee. Each data set is listed in this data release with an accompanying file containing metadata for the dataset. For additional details, please refer to the README.txt file.

Physical and nutrients data were collected from bottle casts from the Gulf of Maine. Data were collected in support of the Gulf of Maine Regional Marine Research Program from 02 August 1932 to 13 July 1991. Physical parameters include temperature and sigma-t. Nutrient parameters include nitrate, nitrate, ammonium, phosphate, silicate, chlorophyll, and phosphate.

As part of the Northeast Coastal and Barrier Network's Estuarine Nutrient Enrichment Monitoring program, Network staff continued to estuarine water quality at several park units. This file contains all data collected during the 2006-2018 field seasons. All data have undergone strict quality control procedures as outlined in the NCBN Estuarine Nutrient Enrichment Monitoring Protocol (https://irma.nps.gov/App/Reference/Profile/661689). Data contained within this database were collected at the following park units: Assateague Island National Seashore, Cape Cod National Seashore, Colonial National Historical Park, Fire Island National Seashore, Gateway National Recreation Area, and George Washington Birthplace National Monument.

As part of the Northeast Coastal and Barrier Network's Estuarine Nutrient Enrichment Monitoring program, Network staff and cooperators continued to monitor seagrass cover and health at several park units. This file contains seagrass monitoring data collected between 2003 and 2024 field season at Assateague Island National Seashore, Cape Cod National Seashore, and Fire Island National Seashore.
