Data

The dataset is composed of two data tables containing information from electrofishing surveys conducted in the Catskill and Adirondack regions. The first data table contains fish collection information and the second data table contains information on the sampled reaches. First posted September 25, 2018, ver. 1.0 Revised July 2019, ver. 2.0 Revised November 2020, ver. 3.0 Revised March 2022, ver.

A study was conducted to provide detailed mapping of glacial aquifers associated with the Fairport-Lyons channel system in Wayne, Ontario, and Seneca Counties, New York. The study was part of the cooperative Detailed Aquifer Mapping Program between the U.S. Geological Survey (USGS) and the New York State Department of Environmental Conservation (NYSDEC). The objective of the study was to character

The dataset is composed of five tables containing environmental DNA (eDNA) and electrofishing data from American eel (Anguilla rostrata) surveys conducted on parts of the Mohawk River watershed and tributaries to the Hudson River in New York. The dataset includes (a) eDNA data from 36 sites in the Mohawk River watershed and adjacent areas including parts of the Eastern Erie Canal, Mohawk River, an

This data release contains phytoplankton classification and enumeration results from two moving boat surveys conducted on July 15 - 18, 2019 and August 19 - 22, 2019. These data were collected from the Caloosahatchee River and estuary, the St. Lucie River and estuary, and Lake Okeechobee with funding provided by the USGS Priority Ecosystems Greater Everglades Program.

A total of 119 passive seismic soundings were collected with Tromino (MoHo s.r.l.) 3-axis seismometers in the Fountain Creek area to partially refine alluvial aquifer thickness (depth to bedrock) estimates, particularly over known or suspected paleochannels. Data were collected during June 21-24, 2021 with a team of 4-5 people, each equipped with a Tromino Blu or Tromino 3G passive seismometer.

This U.S. Geological Survey (USGS) Data Release provides continuously-measured turbidity data collected from ten sites in Kansas and two sites in Virginia from October 2014 to September 2017. All data are reported as raw measured values and are not rounded to USGS significant figures. Water-quality monitors were used to measure turbidity at hourly or fifteen-minute intervals for field comparisons

In October and November 2016-2017, transient electromagnetic (TEM) data, also called time domain electromagnetic (TDEM) surveys, were acquired at 120 locations in the Genesee Valley, Livingston County, New York, in order to characterize the subsurface resistivity structure in support of a U.S. Geological Survey groundwater investigation. The TEM data were collected as part of a project to evaluate

The U.S. Geological Survey, in cooperation with Ashokan Watershed Stream Management Program, investigated the feasibility of bedload monitoring in the upper Esopus Creek watershed, Ulster and Greene Counties, New York (NY), from 2017 to 2020. Traditional bedload samples were collected at two locations: Birch Creek at Big Indian, NY, and Stony Clove at Jansen Rd at Lanesville, NY. Active and passiv

A data release containing information on macroinvertebrate communities and sediment toxicity in the Niagara River and associated areas collected during 2019 and 2020. Sediment toxicity tests were conducted at 60 sites in the Niagara River, 5 sites on Smoke Creek, and 6 sites on Hoyt Lake using two test species, Chironomus dilutus and Hyalella azteca, following USEPA test methods 100.2 and 100.1, r

The data contained in this data release support USGS Scientific Investigations Report 2020-5023, "Distribution of selected hydrogeologic characteristics of the upper glacial and Magothy aquifers, Long Island, New York" (Walter and Finkelstein, 2020). This data release contains estimates of aquifer texture describing the Long Island aquifer system. These estimates in total can be considered a mode

Frequency domain electromagnetic induction (FDEM) data were collected in September 2016 near the Agashashok River and its tributaries, within the Noatak National Preserve near Kotzebue, AK to aid in local permafrost mapping. Data were collected with a GEM-2 instrument (1.6 m coil separation, Geophex, Ltd.); a broadband sensor that measures the bulk conductivity and magnetic susceptibility of the s

In cooperation with the New York City Department of Environmental Protection (NYC DEP), the U.S. Geological Survey (USGS) collected water and bed sediment samples along Alley Creek (Queens, New York) to help determine likely sources of fecal bacteria to the creek and Little Neck Bay. Potential terrestrial sources include stormwater, sewage via combined sewer overflow (CSO) and compromised infrastr
