Annual estimates of road salt application were developed for the conterminous United States for the calendar years 1992 through 2015. The final dataset consists of 24 rasters in Geostationary Earth Orbit Tagged Image File Format (GeoTIFF), one for each year from 1992 through 2015. The final estimates (in pounds) were derived from several data sources, which include road density and proportion of developed land use, depth and spatial extent of long-term snowfall, and the production and distribution of salt sources by state. The extent is the conterminous United States, and the spatial resolution is one-square kilometer.
BLM controlled roads, trails, and closure devices in SWO.
These data were compiled for a study evaluating if rare or endangered fishes (e.g., Humpback Chub and Bonytail) can be transported in a shipping bag with 1-L of water and minimal sedative into remote locations. There were two components (laboratory trials and a field trial) of the study conducted in 2014 and 2017. Laboratory trials were conducted at the Rocky Mountain Research Station in Flagstaff, Arizona to evaluate three sedatives: AquaCalm, Tricaine-S, or Aqui-S 20E. Pilot trials were conducted with five fish (Bonytail) placed in a bag, where induction/recovery times, level of sedation, and fate after release were monitored for fish exposed to a sedative. Fish density increased to 20 fish (Bonytail and Humpback...
