Soil frost measurements have been made at Sleepers River Research Watershed starting in 1983. Measurements were made by U.S. Army Corps of Engineers Cold Regions Research and Engineering Laboratory from 1983 to 1993, followed by the U.S. Geological Survey from 1993 to the present. Measurements started at 5 sites and has increased to 10 sites. Sites range in elevation from 225 to 670 meters and are in a mix of field and forest types. Soil frost measurements are made with tubes filled with methylene blue solution; on freezing, the methylene blue remains in the liquid phase, yielding clear ice that marks the depth of soil frost (Ricard and others, 1976). Soil frost measurements typically are made 2 to 4 times a month...

This dataset describes water yields for precipitation, throughfall, and stemflow for 22 rain events within the 40.5-hectare (ha) forested W-9 catchment at Sleepers River, Vermont. Sampling occurred during the summer and fall of 2018. Dissolved organic carbon (DOC) and total dissolved nitrogen (TDN) concentrations are reported for each sampled event. The dataset also includes 5-minute catchment normalized runoff and the hourly precipitation record for 2017 and 2018 calendar years. Stream water chemistry for DOC and TDN are also included. Major ions and spectroscopic properties are also reported. First posted May 17, 2021, ver. 1.0 Revised September 2022, ver. 2.0
The Sleepers River Research Watershed, near Danville, Vermont, is a 111-square-kilometer watershed established in 1958 by the Agricultural Research Service.The research watershed has since been operated by three other federal agencies: National Weather Service, U.S. Army Cold Regions Research and Engineering Laboratory (CRREL), and U.S. Geological Survey (USGS). USGS started at the site in collaboration with CRREL in 1991 and has been the sole operating entity since 2000. From 1991 to 2017, the research watershed was part of the national 5-site network of the USGS Water, Energy, and Biogeochemical Budgets (WEBB) program. Since 2017 Sleepers has been funded by USGS Land Change Science to continue the core measurements...

This data release supports publications on the Sleepers River Research Watershed near Danville, Vermont. Most of the research at Sleepers River takes place at W-9, the 40.5-hectare forested headwater site. Topics include understanding hydrologic flow paths, biogeochemical cycling, and organic carbon dynamics. Flow and precipitation data are integral to understanding these processes, for example by combining flow and chemical concentrations to compute solute export from the catchment. These records begin in late September 1991 and extend through calendar year 2018. The release includes five-minute data for discharge, daily data for precipitation, runoff,and maximum and minimum air temperature, and an annual tabulation...
A dataset of well information and geospatial data was developed for 426 U.S. Geological Survey (USGS) observation wells in Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. An extensive list of attributes is included about each well, its location, and water-level history to provide the public and water-resources community with comprehensive information on the USGS well network in New England and data available from these sites. These data may be useful for evaluating groundwater conditions and variability across the region. The well list and site attributes, which were extracted from USGS National Water Information System (NWIS), represent all of the active wells in the New England network...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
