This data set includes results for hormone and pharmaceutical compounds analyzed in environmental and quality-control samples collected by the USGS National Water-Quality Assessment Project during 2013 through 2015 for a study of groundwater resources used for drinking-water supply across the United States. Hormone and pharmaceutical results are provided for environmental samples collected at 1,120 wells or springs; selected ancillary data, such as principal aquifer, well depth, and land-use information also are provided for the sampled sites. The types of quality-control samples included in this data set are blanks, matrix spikes, and replicates collected at field sites or field offices. Included in this data...
The Turt cluster is named for a small settlement on the northeastern shore of Lake Khovsgol in northern Mongolia. The cluster crosses the border with Russia, into Buryatia. The cluster was formed around a 6.7 Mw earthquake on January 11, 2021. This event was followed by a large number of aftershocks which could have been included in the cluster but the coverage from local stations for these events was unbalanced and the location calibration tended to become unstable when a large number of them were included. Most of them were only recorded at regional distances. Several of the largest aftershocks are included. It was difficult to obtain adequate azimuthal coverage for this cluster but the final selection of events...

The Potenza cluster is named for the city of Potenza in the region of Basilicata in southern Italy. It includes the Irpinia earthquake (Ms 6.8) on November 23, 1980, and includes a number of moderate-sized events in recent years. The number of seismic stations in the source region increased markedly in 1999 and again in 2010, making direct calibration very easy. The velocity structure was refined with a subset of recent events for which free-depth relocations could be done. All events have depth constraint from near-source or local distance readings, or for a couple events, teleseismic depth phases. ...

Landscape conservation cooperatives (LCCs) are conservation-science partnerships between the U.S. Fish and Wildlife Service, U.S. Geological Survey (USGS), and other federal agencies, states, tribes, NGOs, universities and stakeholders within a geographically defined area. They inform resource management decisions to address national-scale stressors-including habitat fragmentation, genetic isolation, spread of invasive species, and water scarcity-all of which are accelerated by climate change.

This map shows the channel boundary (2011) of the Colorado River mainstem between the Utah Colorado border and the upper pool of Lake Powell, Utah (146 miles). The channel boundary was mapped from public available NAIP imagery flown on June 28, 2011, when the river flow was 886 m3/s at the Cisco gage. The channel is subdivided into channel types: fast water (main channel, secondary channel), and still water types (backwater, isolated pool and tributary channel).

The Kaki cluster is based on the Mw 6.2 mainshock on April 9, 2013, a few tens of km southeast of Bushehr in southern Iran. It's named after a village near the epicenter. The 2013 sequence, including one foreshock and aftershocks through the end of the year, comprises over half of the cluster. Arrival time readings from a temporary seismic network deployed by F. Yamini-Fard (IIEES) to monitor aftershocks are of critical importance to calibrating this cluster. The calibration of this cluster is done by both with direct and indirect technique; near-distance readings up to 0.4 degrees are used for the direct calibration and 18 well calibrated events located by the temporary seismic networks are used for indirect calibration....

The Kobe cluster is named for the city of Kobe, Japan. The cluster is based on the Ms 6.9 earthquake on January 16, 1995 and its aftershocks but it includes more recent events as well. Fitting the pattern of arrivals at local distances required an unusually low crustal P velocity. Number of events: 60 Calibration type: direct calibration using data to 1.0 degrees; hypocentroid calibration level = 0.6 km Epicentral calibration range: 1 - 1 km Date range: 19950116 - 20140805 Latitude range: 34.107 - 35.158 Longitude range: 134.672 - 135.802 Depth range: 14.0 - 22.0 Magnitude range: 3.5...

This shapefile is the official boundary of the Eastern Brook Trout Joint Venture. The boundary was originally developed by the United States Fish and Wildlife Service and was updated in 2013 to reflect revisions from the Eastern Brook Trout Joint Venture, a recognized Fish Habitat Partnership (FHP) of the National Fish Habitat Partnership.

The Samaria cluster is named for the old community of Samaria, Idaho and the Samaria Mountains in southeastern Idaho. The cluster straddles the border with Utah. It contains one large earthquake, an M6.1 event on March 28, 1975, but none of the other events exceeds 4.6 in magnitude. The M6.1 (USGS) earthquake is often referred to as the Pocatello Valley earthquake. About half of the events are from the 1970s and the quality and quantity of arrival time data are poorer than for modern events; in particular they have few S readings. Focal depths are established by free depth relocation but they are rather unstable and the uncertainties are larger than usual. Depths span a large range, roughly from zero to 20 km,...

Hurricane Harvey made landfall near Rockport, Texas on August 25 as a category 4 hurricane with wind gusts exceeding 150 miles per hour. As Harvey moved inland the forward motion of the storm slowed down and produced tremendous rainfall amounts to southeastern Texas and southwestern Louisiana. Historic flooding occurred in Texas and Louisiana as a result of the widespread, heavy rainfall over an 8-day period in Louisiana in August and September 2017. Following the storm event, U.S. Geological Survey (USGS) hydrographers recovered and documented 2,123 high-water marks in Texas, noting location and height of the water above land surface. Many of these high-water marks were used to create flood-inundation maps for...
