The data set consists of fecal indicator bacteria and microbial source tracking marker concentrations in water and sediments across multiple seasons. Samples were collected during baseflow from a variety of watershed classifications. Portions of this dataset are inaccessible because: Researchers are still working on manuscripts out of this data set and can't be released at this time. They can be accessed through the following means: Contacting corresponding author for product. Format: The data set will contain environmental parameters, fecal indicator bacteria concentrations and DNA source tracking markers. This dataset is associated with the following publication: Bradshaw, J.K., B. Snyder, A. Oladeinde, D. Spidle, M. Berrang, R. Meinersmann, B. Oakley, R. Sidle, K. Sullivan , and M. Molina.

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).

Data represent response variables from a series of mesocosm experiments to assess how estuarine macrophyte communities respond to nitrogen loading under two different thermal regimes.
