This data release supports analyses of the relations between monthly average nutrient concentrations in the Herring River on the ebb tide near Wellfleet Massachusetts and monthly average precipitation, temperature, runoff, solar radiation, ocean water temperature, mean sea level, nutrient concentrations in Wellfleet Harbor, and atmospheric deposition of nitrogen 2015-2021. The Environmental_Variables.csv file contains the monthly average precipitation, temperature, runoff, solar radiation, ocean water temperature, mean sea level, nutrient concentrations in Wellfleet Harbor, and atmospheric deposition of nitrogen data. The Velocity_andgage_height.csv file contains the data on surface water velocity that were used...
Staff from the Cape Cod National Seashore, National Park Service (CACO NPS) began limited water-quality data collection in the Herring River Estuary as early as 1984. In 2006 a monthly sampling program was established for 14 sites to monitor nutrient concentrations, dissolved oxygen, and other constituents. This monitoring program is ongoing and has been supplemented with data from other CACO NPS projects and cooperative monitoring with the U.S. Geological Survey. With the anticipated restoration of the estuary, which has been diked off from the ocean for over 100 years, these data are critical in supporting the characterization of pre-restoration water quality. The data collected in the estuary from 1984-2017 have...

Note: this data release has been withdrawn. Please see new data release here: https://doi.org/10.5066/P13LGNTT. Geochemical data were obtained to investigate the fate and transport of nitrogen in a subterranean estuary near East Falmouth, Massachusetts. The goal of this investigation was to assess nitrogen attenuation in the aquifer under the Eel River Estuary and the adjacent peninsula that was densely populated with residences having septic systems and legacy cesspool inputs of inorganic nitrogen. This estuary is one of many small embayments on Cape Cod where nutrient enrichment can lead to eutrophication and is a major concern for water-quality impairment. Groundwater water-quality data were collected from...
This data release provides data in support of an assessment of changes in slope of the concentration-discharge relation for total organic carbon in eight major rivers at gaging stations in Connecticut from October 1972 to September 2019 (U.S. Geological Survey water years 1973 to 2019). The rivers include the Connecticut at Thompsonville (01184000), Housatonic at Stevenson (01205500), Quinebaug at Jewett City (01127000), Farmington at Tariffville (01189995), Shetucket at Willamantic (01122500), Naugatuck at Beacon Falls (011208500), Quinnipiac at Wallingford (01196500), and Salmon at East Hampton (01193500). The assessment is described in the article “An increase in the slope of the concentration discharge relation...

This data release supports an analysis of changes in dissolved organic carbon (DOC) concentration and in the slope of the concentration-discharge relation in the Sleepers River Research Watershed W9 near North Danville, Vermont 1991 to 2018. The data release includes pre-processed model inputs and model outputs. W9 is a 40.5-hectare forested sub-watershed of the Sleepers River Research Watershed that was originally established by the U.S. Department of Agriculture in 1959 and has been intensively studied by the USGS since 1991. The W9 headwater sub-watershed drains to Pope Brook and is gaged at USGS station ID 01135100. Pope Brook flows into Sleepers River and ultimately into the Connecticut River. Two models...

This data release provides data in support of an assessment of water quality and discharge in the Herring River at the Chequessett Neck Road dike in Wellfleet, Massachusetts, from November 2015 to September 2017. The assessment was a cooperative project among the U.S. Geological Survey, National Park Service, Cape Cod National Seashore, and the Friends of Herring River to characterize environmental conditions prior to a future removal of the dike. It is described in U.S. Geological Survey (USGS) Scientific Investigations Report "Assessment of Water Quality and Discharge in the Herring River, Wellfleet, Massachusetts, November 2015 – September 2017" (in press). This data release is structured as a set of comma-separated...
This dataset includes CSV data files containing environmental data that may be associated with the occurrence and toxicity of the diatom Pseudo nitzschia in Frenchman Bay, Maine, that can form harmful algal blooms and produce the toxin domoic acid. The dataset covers the period 2010 through 2022 or shorter period depending on the variable. Elevated concentrations of domoic acid in Pseudo nitzschia can lead to the contamination of shellfish, threats to human health and closures of shellfish harvesting areas. This dataset was compiled in cooperation with the National Park Service. The file “Site_Infomation_v4.csv” contains the latitudes and longitudes for the locations where Pseudo nitzschia cells were enumerated,...
This data release provides analytical and other data in support of an analysis of nitrogen transport and transformation in groundwater and in a subterranean estuary in the Eel River and onshore locations on the Seacoast Shores peninsula, Falmouth, Massachusetts. The analysis is described in U.S. Geological Survey Scientific Investigations Report 2018-5095 by Colman and others (2018). This data release is structured as a set of comma-separated values (CSV) files, each of which contains data columns for laboratory (if applicable), USGS Site Name, date sampled, time sampled, and columns of specific analytical and(or) other data. The .csv data files have the same number of rows and each row in each .csv file corresponds...

Geochemical data were obtained to investigate the fate and transport of nitrogen in a subterranean estuary near East Falmouth, Massachusetts. The goal of this investigation was to assess nitrogen attenuation in the aquifer under the Eel River estuary and the adjacent peninsula, introduced as inorganic nitrogen that was densely populated with residences havingfrom residential septic systems and legacy cesspool inputs of inorganic nitrogens. Groundwater-quality data were collected from three transects from a total of twenty-seven locations that were sampled between November 2015 and October 2016. Samples were analyzed for pH, dissolved oxygen, temperature, specific conductance, nitrate + nitrite, ammonium, total...
