The North American Breeding Bird Survey in Mexico, 2008-2018 - unprocessed data The North American Breeding Bird Survey in Mexico, 2008-2018 - unprocessed data
This dataset includes all North American Breeding Bird Survey data collected in Mexico between 2008-2018. These data were used as the basis for all analyses discussed in an associated publication: The North American Breeding Bird Survey in Mexico, 2008-2018 - A Status Report; https:doi.org/10.3133/cir1479. The records include avian point count data for all reported taxa (species, races...
Geospatial bathymetry datasets for New York City's East of Hudson Reservoirs and Controlled Lakes Geospatial bathymetry datasets for New York City's East of Hudson Reservoirs and Controlled Lakes
From May 2017 to November 2019, the U.S. Geological Survey conducted bathymetry surveys of New York City's East of Hudson Reservoirs. The East of Hudson Reservoirs consist of 16 reservoirs and controlled lakes in Putnam and Westchester County, New York, including Amawalk Reservoir, Bog Brook Reservoir, Boyd Corners Reservoir, Cross River Reservoir, Croton Falls Reservoir, Diverting...
Pesticides in Weekly Water Samples from the NAWQA California Regional Stream Quality Assessment (2017) Pesticides in Weekly Water Samples from the NAWQA California Regional Stream Quality Assessment (2017)
Dissolved pesticides were measured in weekly water samples from 85 wadeable streams in Central Coastal California over a variable six-week period during March-May, 2017, as part of the California Stream Quality Assessment (CSQA) study conducted by the U.S. Geological Survey's (USGS) Regional Stream-Quality Assessment (RSQA) Project. The 85 streams consisted of 40 urban sites (5...
Chemical analyses and precipitation depth data for wet deposition samples collected as part of the National Atmospheric Deposition Program in the Colorado Front Range, 2017-2019 Chemical analyses and precipitation depth data for wet deposition samples collected as part of the National Atmospheric Deposition Program in the Colorado Front Range, 2017-2019
The USGS Precipitation Chemistry Quality Assurance Project (PCQA) conducts research using the infrastructure of the National Atmospheric Deposition Program (NADP) National Trends Network (NTN). Beginning in December 2016, the PCQA installed and began operating NTN monitoring sites in the Denver-Boulder metropolitan area to study urban reactive nitrogen wet deposition. Precipitation depth...
Water-quality and stream discharge data for estimation of nitrogen loads in the South Platte River, Denver, CO, 2017-2018 Water-quality and stream discharge data for estimation of nitrogen loads in the South Platte River, Denver, CO, 2017-2018
The purpose of this data release is to provide the original data, analysis methods, and nitrogen loading models in support of a study of the upper South Platte River annual total nitrogen loads attributed to atmospheric deposition of reactive nitrogen during 2017-2018. The data release includes water-quality and stream discharge data and associated predictive regression models used in...
