Compilation of Images from Rivers Reaches across the United States (CIRRUS) Compilation of Images from Rivers Reaches across the United States (CIRRUS)
This data release provides a Compilation of Images from River Reaches across the United States (CIRRUS). These images were retrieved programmatically using the Google Maps Application Programming Interface (API). The data set consists of a total of 281,024 individual images from rivers throughout the contiguous U.S. and Alaska, with an emphasis on locations likely to have rapids. For the...
Atlantic and Gulf Coast Sandy Coastline Topo-Bathy Profile and Characteristic Database Atlantic and Gulf Coast Sandy Coastline Topo-Bathy Profile and Characteristic Database
Seamless topographic-bathymetric (topo-bathy) profiles and their derived morphologic characteristics were developed for sandy coastlines along the Atlantic and Gulf coasts of the United States. The topo-bathy profiles are published as a database in the Hierarchical Data Format version 5 (HDF5) which contain cross-shore distance coordinates, Universal Transverse Mercator (UTM) coordinate...
Argon data for samples from Sheep Creek and other mineral systems in central and western Montana, USA Argon data for samples from Sheep Creek and other mineral systems in central and western Montana, USA
This dataset includes 40Ar/39Ar data for 14 samples from the Sheep Creek carbonatite occurrence and other mineral systems in central and western Montana, USA. Samples were acquired from this area by Christopher Gammons and his students (Montana Technological University). Mineral separates of biotite and sericite from the samples were analyzed in the Denver Argon Geochronology Laboratory...
Data on Lepidium draba seed set and genetic diversity in northern Colorado Data on Lepidium draba seed set and genetic diversity in northern Colorado
Data were collected on the seed production and genetic diversity of Lepidium draba, an invasive plant. Site characteristics were also measured for 26 sites throughout northern Colorado. In addition, a pollen supplementation experiment was conducted at six of those sites, in which L. draba plants were pollinated with within-population pollen, among-population pollen, or were not...
Raster layers of optimal protection and restoration sites, ecological status, greater sage-grouse lek abundance, and connectivity to prioritize multi-species, sagebrush ecosystem management across Wyoming, USA Raster layers of optimal protection and restoration sites, ecological status, greater sage-grouse lek abundance, and connectivity to prioritize multi-species, sagebrush ecosystem management across Wyoming, USA
This data release includes a set of 25 rasters representing solutions (and associated input data) to two sagebrush conservation problems that identify optimal sites across the state of Wyoming for protection or restoration action (based on management-relevant inputs and constraints). The arid sagebrush-steppe ecosystems of western North America are undergoing substantial loss and...
