The data herein are geochemical (from X-Ray fluorescence spectrometry), grain size (percent clay, silt, sand), lithological (loss on ignition data), bathymetric, reconstructed IVT, and radioactive isotopes (14-C, 210-Pb, 226-Ra, and 137-Cs). These data were collected from sediments from Leonard Lake, Mendocino County, California, USA starting in 2014. Together, these data provide evidence for a record of extreme precipitation going back three millennia, showing regional pluvial and drought cycles.

Note: this data release is currently being revised and is temporarily unavailable. The Monitoring Trends in Burn Severity (MTBS) Program assesses the frequency, extent, and magnitude (size and severity) of all large wildland fires (wildfires and prescribed fires) in the conterminous United States (CONUS), Alaska, Hawaii, and Puerto Rico for the period 1984 and beyond. All fires reported as greater than 1,000 acres in the western U.S. and greater than 500 acres in the eastern U.S. are mapped across all ownerships. MTBS produces a series of geospatial and tabular data for analysis at a range of spatial, temporal, and thematic scales and are intended to meet a variety of information needs that require consistent data...

This data release contains U.S. Geological Survey (USGS) field survey data files for selected stream crossing locations in the Squannacook River Basin, north-central Massachusetts. The surveyed stream cross sections and culvert dimensions were used in developing U.S. Army Corps of Engineers (USACE) Hydrologic Engineering Center’s River Analysis System (HEC-RAS) hydraulic models. The data also include original survey notes, survey sketches, and photographs for each field survey conducted at stream crossing locations. The field survey documented and surveyed five stream cross sections for the upstream approach, upstream culvert face, top of road deck, downstream culvert face, and downstream exit. Global Navigation...
