PROBLEM The valley‐fill aquifer in the lower Fall Creek valley (designated as aquifer 4, fig. 1), within the Towns of Dryden and Groton, was mapped by Miller (2000) and identified as one of 17 unconsolidated aquifers in Tompkins County that need to be studied in more detail. The east end of the valley (near the Tompkins and Cortland County border) is on the backside of a large morainal plug, which is part of the Valley Heads Moraine. A large system of springs discharge from the backside of the moraine and forms part of the headwaters to Fall Creek. The valley‐fill aquifer thins and pinches out to the west (figs. 1 and 2)— where the valley is floored by bedrock and becomes a “hanging valley” to Cayuga Lake trough....

The U.S. Geological Survey (USGS) is providing a polygon feature class delineating the extent of Glacial Lake Great Bend within the Binghamton East 1:24,000 quadrangle of south-central Broome County, New York, 2020. The shapefile was created and intended for use with geographic information system (GIS) software. A companion report, USGS Scientific Investigations Report 2021-5026 (Van Hoesen and others, 2021; https://doi.org/10.3133/sir20215026) further describes data collection and map preparation.

The U.S. Geological Survey (USGS) is providing a polygon feature class containing the approximate locations and confining units of the unconfined and confined aquifers within the Binghamton East 1:24,000 quadrangle of south-central Broome County, New York, 2020. The shapefile was created and intended for use with geographic information system (GIS) software. A companion report, USGS Scientific Investigations Report 2021-5026 (Van Hoesen and others, 2021; https://doi.org/10.3133/sir20215026) further describes data collection and map preparation.

The Shimian cluster is named for Shimian County in Sichuan Province, China. The cluster is based on a 6.6 Mw earthquake on September 5, 2022, and includes a 6.0 Ms event, on January 15, 1975. Location calibration of this cluster depends completely on data from the provincial seismograph networks in the area that was collected by Sun Ruomei. In order to include enough events (with depth control) to obtain good azimuthal coverage and enough arrival time data at local distances for robust statistics, the area of the cluster is larger than usual, over 200 km across. All events are recorded to teleseismic distances and all have depth control, although it is a bit weak in some cases. It appears that seismicity in this...

This data release supports interpretations of field-observed root distributions within a shallow landslide headscarp (CB1) located below Mettman Ridge within the Oregon Coast Range, approximately 15 km northeast of Coos Bay, Oregon, USA. (Schmidt_2021_CB1_topo_far.png and Schmidt_2021_CB1_topo_close.png). Root species, diameter (greater than or equal to 1 mm), general orientation relative to the slide scarp, and depth below ground surface were characterized immediately following landsliding in response to large-magnitude precipitation in November 1996 which triggered thousands of landslides within the area (Montgomery and others, 2009). The enclosed data includes: (1) tests of root-thread failure as a function of...

The Denver fossil algae database were gathered from the inception of Denver Region in 1953 by Richard Rezak. His specialty was algae, carbonate platforms, and off-shore modern reefs. He developed a very useful litho-stratigraphic tool while studying Proterozoic algae and stromatolites in Glacier National Park. This lead to his studies of modern analogs in the Caribbean and South Seas. His catalogs were converted into digital form, Excel and Filemaker Pro database. The Catalog consist of 1001 fossil localities. His supplementary data has been added whenever possible - sources field map locality points, E&R files with enhanced faunal lists, as well as formal publications

Note: This data release has been revised. Find version 2.0 here: https://doi.org/10.5066/F75H7FH3. Groundwater withdrawal estimates from 1913-2010 for the Death Valley regional groundwater flow system (DVRFS) are compiled in a Microsoft® Access database. This database updates two previously published databases (Moreo and others, 2003; Moreo and Justet, 2008). A total of about 38,000 acre-feet of groundwater was withdrawn from the DVRFS in 2010, of which 47 percent was used for irrigation, 22 percent for domestic, and 31 percent for public supply, commercial, and mining activities. The updated database was compiled to support ongoing efforts to model groundwater flow in the DVRFS. References cited: Moreo, M.T.,...

This dataset comprises a vector shapefile of the Puerto Rico geologic map from Bawiec et al. (1999), clipped to study areas in the Lares, Utuado, and Naranjito municipalities, with a modified basal contact of the Tertiary Lares Limestone (Tla) re-mapped using a lidar-derived digital elevation model (DEM) (USGS, 2018). The limestone unit of interest forms a prominent break in slope with the underlying geologic units, and this break in slope was mapped as the Tla basal contact. Only the southern contact of the Tla unit was modified.

Recreational angling in the U.S. represents a large group of people that catch and harvest fish for a variety of reasons, including for relaxation, adventure, social motivations, and consumption. Collectively, recreational anglers can exert pressures on both economies and fishery resources. Fish removals by anglers represent an important source of mortality data when trying to understand fish populations, and this information is even more important when the fishery is dominated by recreational and subsistence fishing. Currently, the magnitude of recreational angling is measured at local scales (for example, at a specific lake or stream) and the process to collect information from anglers varies widely by state...
