The "MasterDB-csv-final2" dataset includes 548 laboratory measurements of sediment total mercury (STHg, nanograms per gram of soil, dry), bulk density (BD, grams per cm3 of soil, dry), percent of soil organic matter (%OM, loss on ignition, LOI), percent of soil organic carbon (%SOC, calculated using the Redfield's number), RHgC (Hg to carbon ratio), and age (YBP) from 13 permafrost cores collected from 2004 to 2012 in the interoir and northern slope of Alaska by trained personnel from the U.S. Geological Survey National Research Program and the National Snow and Ice Data Center in Boulder, Colorado.

This report contains water-quality and sediment-quality data from samples collected in the Yukon River Basin from March through September during the 2004 water year (WY). Samples were collected throughout the year at five stations in the basin (three on the main stem Yukon River, one each on the Tanana and Porcupine Rivers). A broad range of physical, chemical, and biological analyses are presented.
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...

Total mercury, bulk density, percent organic matter, and percent organic carbon measured in permafrost cores from the interior and northern slope of Alaska and previously published studies
This data release contains two datasets (see child items below). The first dataset, "MasterDB-csv-published-final.csv", includes 11,000 published measurements of sediment total mercury (STHg, nanograms per gram of soil, dry), bulk density (BD, grams per cm3 of soil, dry), percent of soil organic matter (%OM, loss on ignition, LOI), percent of soil organic carbon (%SOC, calculated using the Redfield's number), RHgC (Hg to carbon ratio), and age (YBP) from 13 published studies conducted throughout the arctic and subarctic. The second dataset, "MasterDB-csv-final2.csv", includes 548 laboratory measurements of sediment total mercury (STHg, nanograms per gram of soil, dry), bulk density (BD, grams per cm3 of soil,...

The Shingobee Headwaters Aquatic Ecosystem Project is a long-term, multi-disciplinary monitoring and research study of a 28-square-kilometer headwaters watershed in north-central Minnesota that began in 1978. Emphasis is on processes related to hydrology, limnology, geochemistry, and watershed ecology and the land-water and atmosphere-water interfaces. Lakes are a substantial focus and integrator of many of the physical, chemical, and biological processes that occur within watersheds. Large volumes of groundwater discharge provide resilience to lakes and wetlands in response to anthropogenic and climatic influences. Minnesota, located in north-central USA, has been both warmer and wetter than normal during the past...

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.
