Northeastern boreal forests are an important habitat type for many wildlife species, including migratory birds and moose. These animals play vital roles in the boreal forest ecosystem, are a source of pleasure for bird and wildlife watchers, and contribute to tourism revenue for many communities. However, moose and migratory birds are thought to be particularly vulnerable to the impacts of climate change. For example, in New York’s Adirondack Park system, five species of boreal birds have shown occupancy declines of 15% or more. Meanwhile, moose are threatened by winter ticks that thrive in warmer climates and spread disease. A 2018 New York Department of Environmental Conservation (NYDEC) report found that there...

The Caldiran cluster is named after the town of Cadiran in the district of Van, Turkey. This cluster consists of 83 events, including the magnitude 7.3 Caldiran earthquake on November 24, 1976 and five of its aftershocks, as well as several recent moderate magnitude events in 2000s, the largest being the magnitude 5.1 October 20, 2003 earthquake. A. Ghods repicked many of the arrival times from Iranian networks, including S-P data from the INSM network of accelerometers (BHRC). Focal depths of 24 events are set with near-distance picks, and 44 are constrained with local-distance picks. The remaining events in the cluster are held at a default depth of 12 km. ...

The Siah Kuh cluster is named after the village of Siah Kuh (Black Mountain) in Gilan Province, Iran. It consists of only 16 events, the largest being the M4.3 event on September 5, 2005. There's a fairly large azimuthal gap to the east, but the cluster is well calibrated at a level of 1.4 km by using data up to 1.6 degrees. Focal depths of almost all events are constrained with local-distance readings, except for the oldest event in the cluster (January 6, 2005) which is set to a default of 11 km. Number of events: 16 Calibration type: direct calibration using data to 1.6 degrees; hypocentroid...

This data release contains coastal wetland synthesis products for the geographic region from Jamaica Bay to western Great South Bay, located in southeastern New York State. Metrics for resiliency, including unvegetated to vegetated ratio (UVVR), marsh elevation, and mean tidal range, are calculated for smaller units delineated from a Digital Elevation Model, providing the spatial variability of physical factors that influence wetland health. Through scientific efforts initiated with the Hurricane Sandy Science Plan, the U.S. Geological Survey has been expanding national assessment of coastal change hazards and forecast products to coastal wetlands with the intent of providing Federal, State, and local managers with...

The Zahle cluster is named for the city of Zahle, Lebanon, but it covers most of the country and includes some offshore events as well. Most events are small and there are few arrival time data beyond ~30° epicentral distance. The distribution of stations is quite good and the calibration analysis is robust. All events have depth constraint. Depths range through most of the crust. Number of events: 69 Calibration type: direct calibration using data to 0.7 degrees; hypocentroid calibration level = 1.0 km Epicentral calibration range: 1 - 3 km Date range: 19950423 - 20180107 Latitude range: ...

The U.S. Geological Survey (USGS) worked in cooperation with the Federal Emergency Management Agency (FEMA) to document the August and September, 2017 Hurricane Harvey storm event in southeastern Texas and southwestern Louisiana. Hurricane Harvey was the most significant rainfall event in United States history in scope and rainfall totals since rainfall records began during the 1880s. From August 25 through September 1, 2017, some areas in southeastern Texas received more than 60 inches of rain; large areas received more than 40 inches of rain. This data release contains the flood inundation polygons, flood-depth rasters, mapped boundaries, and high-water mark (HWM) locations for the selected river basins, coastal...

The U.S. Geological Survey (USGS) in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, and Lone Star Groundwater Conservation District has produced this dataset of groundwater‐level altitudes and groundwater‐level altitude changes in the Chicot, Evangeline, and Jasper aquifers in the Houston‐Galveston region, Texas. This dataset shows current‐year (2018) groundwater‐level altitudes for each aquifer, 5‐year (2013‐18) groundwater‐level changes for each aquifer, long‐term (1990‐2018 and 1977‐2018) groundwater‐level changes for the Chicot and Evangeline aquifers, and long‐term (2000‐2018) groundwater‐level change for the Jasper aquifer. The groundwater‐level measurements...

Inland fishes provide important ecosystem services to communities worldwide and are especially vulnerable to the impacts of climate change. Fishes respond to climate change in diverse and nuanced ways which creates challenges for practioners of fisheries conservation and management. Although climate change is a known factor affecting fish globally, a comprehensive online, public database of how climate change has impacted inland fishes worldwide and management practices to address these impacts does not exist. We conducted an extensive, systematic primary literature review to identify peer-reviewed journal publications with projected and documented examples of climate change impacts on inland fishes. From this standardized...

Since 2008, over 1,400 quadrats and about 2,500 mussels have been systematically sampled within West Newton Chute (WNC), contributing to a diverse assemblage of 25 live species, including 2 federally endangered species, and 10 Minnesota listed species. West Newton Chute is a 2.4 km long side channel in Navigation Pool 5 of the Upper Mississippi River and has an overall aquatic area of ~75 ha. The Minnesota Department of Natural Resources has been quantitatively sampling a mussel bed here (~650 meters long X 170 meters wide) annually since 2008. About 200 systematically-placed 0.25 m2 quads are sampled annually and the quads are spaced ~25 m apart. Briefly, divers excavate substrates to a depth of ~15 cm and place...

The US Geological Survey, in cooperation with the National Park Service, mapped 35 7.5-minute quadrangles, within a 2-mile-wide+ corridor centered on the Parkway, from BLRI (Blue Ridge Parkway) Mile Post (MP) 0 near Afton, Virginia southward to MP 218 at Cumberland Knob, approximately 1.3 km south of the Virginia – North Carolina State Line. Detailed bedrock geologic mapping for this project was conducted at 1:24,000-scale by systematically traversing roads, trails, creeks, and ridges within and adjacent to the 2-mile-wide+ corridor along the 216.9-mile length of the BLRI in Virginia. Geologic data at more than 23,000 station points were collected during this project (September 2009 – February 2014), with approximately...

These data are a geospatial representation of potential damage resulting from fires following the HayWired earthquake scenario, a magnitude 7.0 earthquake occurring on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. These data take information about prevailing conditions (for example, average wind speed and direction) and potential hazard information (for example, ground shaking and liquefaction) and model the resulting fire-based damages which could occur following the HayWired scenario mainshock. The results are presented as a series of Voronoi polygons centered on known fire stations in the region. This vector .SHP dataset was developed and intended for use in GIS applications...

The Grand Canyon geologic field photograph collection contains 1,211 geotagged photographs collected during 43 years of geologic mapping from 1967 to 2010. The photographs document some key geologic features, structures, and rock unit relations that were used to compile nine geologic maps of the Grand Canyon region published at 1:100,000 scale, and many more maps published at 1:24,000 scale. Metadata for each photograph include description, date captured, coordinates, and a keyword system that places each photograph in one or more of the following categories: arches and windows, breccia pipes and collapse structures, faults and folds, igneous rocks, landslides and rockfalls, metamorphic rocks, sedimentary rocks,...
