Continuous Records of Shallow Soil Temperature and Moisture in the Noatak River Basin, Alaska Continuous Records of Shallow Soil Temperature and Moisture in the Noatak River Basin, Alaska
Soil moisture and temperature were measured at four shallow depths in multiple locations within tundra and forested landscapes of the Agashashok River basin. The measurements were made continuously beginning in 2015 until the most recent download in summer, 2019 or until the sensors or loggers failed.
Meteorological Data from Two Locations in the Agashashok River Watershed, Northwestern Alaska, 2015 to 2017 Meteorological Data from Two Locations in the Agashashok River Watershed, Northwestern Alaska, 2015 to 2017
Meteorological data was collected from two locations in the Agashashok River Watershed, one high in the drainage located on tundra (67.5440 N, 161.6828 W) and a second on a rocky knoll near the watershed mouth (67.2821 N, 162.5841 W). The data contain information on air temperatures, rainfall, barometric pressure, relative humidity, incoming and outgoing radiation, and wind speed and...
Electron microprobe analyses of hydrothermal muscovite crystals from gold-bearing quartz veins of the Klamath Mountains, California, 2014 and 2019 (ver. 1.1, June 2022) Electron microprobe analyses of hydrothermal muscovite crystals from gold-bearing quartz veins of the Klamath Mountains, California, 2014 and 2019 (ver. 1.1, June 2022)
This data release provides geochemical results of in situ electron probe microanalyses of hydrothermal muscovite associated with gold-bearing quartz veins from the Klamath Mountains, California. Samples were collected from eight different mines in the summer of 2013 and electron probe microanalyses were carried out May 27, 2014 and November 12, 2019.
Chemical and biological exposure bioassay data from sediment collected within the Grand Calumet River, Indiana, USA Chemical and biological exposure bioassay data from sediment collected within the Grand Calumet River, Indiana, USA
The Grand Calumet River (GCR), located in northern Indiana, is contaminated due to a wide range of historical industrial activities. Short-term and long-term sediment exposure bioassays with the amphipod Hyalella azteca, the midge Chironomus dilutus, and the mussel Lampsilis siliquoidea were conducted with samples collected in 2013, 2015, and 2017, from up to 26 sites, including both...
Lidar-derived Beach Morphology (Dune Crest, Dune Toe, and Shoreline) for U.S. Sandy Coastlines Lidar-derived Beach Morphology (Dune Crest, Dune Toe, and Shoreline) for U.S. Sandy Coastlines
The U.S. Geological Survey (USGS)Coastal Change Hazards Technical Capabilities and Applications (TCA) project aims to identify areas of the nation’s coastline that are most vulnerable to extreme storms and long-term shoreline change. These assessments require coastal elevation data across diverse geographic regions and covering a time span of many years. The datasets published here...
