Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Histopathology of tri-colored bats (Perimyotis subflavus) exposed to the fungus Pseudogymnoascus destructans under varying temperature and humidity conditions Histopathology of tri-colored bats (Perimyotis subflavus) exposed to the fungus Pseudogymnoascus destructans under varying temperature and humidity conditions
This work is part of an experimental trial investigating the effects of microclimate conditions of temperature and humidity on a fungal pathogen, Pseudogymnoascus destructans (Pd), that causes white-nose syndrome (WNS) disease in hibernating bats. As part of the trial, tri-colored bats (Perimyotis subflavus) were exposed to Pseudogymnoascus destructans (Pd) and allowed to hibernate in...
Risk assessment of chanchita Cichlasoma dimerus (Heckel, 1840), a newly identified non-native cichlid fish in Florida Risk assessment of chanchita Cichlasoma dimerus (Heckel, 1840), a newly identified non-native cichlid fish in Florida
Cichlasoma dimerus was only recently discovered in Florida and little is known of its dispersal abilities and potential impacts. Many factors likely contribute to the variability in establishment and spread of non-native fishes in Florida, including biotic (e.g., predation and competition) and abiotic variables (e.g., cold tolerance, low-oxygen tolerance). Of the abiotic variables, cold...
Whole rock geochemistry and comparative leachability of variably bleached and red sandstones of the Permian Cutler Formation, Mesa County, Colorado Whole rock geochemistry and comparative leachability of variably bleached and red sandstones of the Permian Cutler Formation, Mesa County, Colorado
Forty samples of outcropping rock samples were collected from the Permian Cutler Formation exposed in the Sinbad Valley, Mesa County, Colorado by USGS volunteer Jon Thorson. This sample set includes 13 pairs of co-existing red unaltered and yellow-grey bleached sandstone. The decimal latitude and longitude locations of the sample collection sites are listed in the "All_Rock_Data"...
Fluvial Erosion Hazard Rapid Geomorphic Assessment Data from the Marengo Watershed, Ashland County, Wisconsin Fluvial Erosion Hazard Rapid Geomorphic Assessment Data from the Marengo Watershed, Ashland County, Wisconsin
An extreme flood in 2016 caused widespread culvert blockages and road failures across northern Wisconsin, including extensive damage along steep tributaries and ravines in the Marengo River watershed. Along with the flooding, there were fluvial erosion hazards (FEH) associated with a large amount of erosion in headwater areas. Of special concern were FEHs associated with gullying, loss...
Earthquake triggered ground failure associated with the M7.1 2018 southcentral Alaska Earthquake (ver. 2.0, December 2023) Earthquake triggered ground failure associated with the M7.1 2018 southcentral Alaska Earthquake (ver. 2.0, December 2023)
The November 30, 2018, magnitude (Mw) 7.1 Anchorage, Alaska earthquake triggered substantial ground failure throughout Anchorage and surrounding areas (Grant et al., 2020; Jibson et al., 2020). The earthquake was an intraslab event with a focal depth of about 47 km and an epicenter about 16 km north of the city of Anchorage. Peak ground accelerations reached ∼30% g. Despite the...
Database for the geologic map of the upper Santa Cruz River basin, southern Arizona Database for the geologic map of the upper Santa Cruz River basin, southern Arizona
This digital publication contains the database, base maps, and style files used to build the geologic map of the upper Santa Cruz River basin in southern Arizona published in U.S. Geological Survey Scientific Investigations Map 3490 (Page and others, 2023). Shapefiles are also included for the user’s convenience. In the database, there are polygon features outlining the map units and...
GW/SW-MST: A Groundwater/Surface-Water Method Selection Tool GW/SW-MST: A Groundwater/Surface-Water Method Selection Tool
The Groundwater/Surface-Water Method Selection Tool (GW/SW-MST) is a spreadsheet-based tool to help practitioners identify methods for use in groundwater/surface-water (GW/SW) exchange and hyporheic studies. GW/SW exchange and hyporheic processes are topics receiving increasing attention from the hydrologic community. Hydraulic, chemical, temperature, geophysical, and remote sensing...
Hakalau Forest National Wildlife Refuge host plant associations of Lepidoptera, 2016-2017 Hakalau Forest National Wildlife Refuge host plant associations of Lepidoptera, 2016-2017
This data release includes metadata and tabular data that documents species of caterpillars collected from different plant species at Hakalau Forest National Wildlife Refuge during 2017-2018. Data sets document (1) numbers of caterpillars collected on each plant species, (2) caterpillar host plant associations, (3) the fate of caterpillars during rearing, (4) types of mandibles possessed...
Biomass and methylmercury concentrations in biweekly biological samples from Brownlee and Oxbow Reservoir outflows, Snake River Hells Canyon Complex (Idaho-Oregon), 2018-2019 Biomass and methylmercury concentrations in biweekly biological samples from Brownlee and Oxbow Reservoir outflows, Snake River Hells Canyon Complex (Idaho-Oregon), 2018-2019
This dataset describes biomass and methylmercury concentrations in zooplankton, other invertebrates, fish, and coarse and fine detritus samples collected at the outflow locations of Brownlee and Oxbow Reservoirs in the Snake River Hells Canyon Complex. Based on the sampling locations, the sampled materials were presumed to have flowed through the dam turbines or over the spillway...
Beach Profile Data Collected from Madeira Beach, Florida Beach Profile Data Collected from Madeira Beach, Florida
This dataset, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center, provides beach profile data collected at Madeira Beach, Florida. Data were collected by a walking person equipped with a Global Positioning System receiver and a GPS antenna affixed to a surveying backpack. The horizontal position data are given in the Universal Transverse Mercator (UTM...
