Between September and November each year, nearly the entire world population of Pacific black brant (Branta bernicla nigricans) stages at Izembek Lagoon and surrounding estuaries (hereafter: Izembek Complex). The Izembek Complex is a unique area of protected brackish waters, supporting one of the world’s largest eelgrass beds and a diverse array of wildlife. The Alaska Fall Brant Survey has been conducted annually since 1976 in late-September through October, to provide an index of abundance for the entire post-breeding Pacific black brant population (Branta bernicla nigricans), while secondarily, providing annual fall population indices for cackling geese (Branta hutchinsii), emperor geese (Anser canagicus), and...

Digital datasets were used to develop basin characteristics values that are used in multiple regression equations and tested for the use in predicting flow-duration curves (FDCs) in ungaged areas of Indiana. Several basin characteristics are easily derived from StreamStats basin delineations, such as basin area (https://streamstats.usgs.gov/ss/). Other basin characteristics require ancillary datasets as input. The data provided through this data release are those data that have been collected, tested, and ultimately selected as a basis for FDC development. These include PRISM 3-Month Average Precipitation, Thickness and Coarseness of Quaternary Sediments, and Soil Available Water Capacity. There are 6 continuous...
These datasets provide early estimates of 2024 fractional cover for exotic annual grass (EAG) species and one native perennial grass species on a weekly basis from April to late June. Typically, the EAG estimates are publicly released within 7-13 days of the latest satellite observation used for that version. Each weekly release contains five fractional cover maps along with their corresponding confidence maps for: 1) a group of 16 species of EAGs, 2) cheatgrass (Bromus tectorum); 3) Field Brome (Bromus arvensis); 4) medusahead (Taeniatherum caput-medusae); and 5) Sandberg bluegrass (Poa secunda). These datasets were generated leveraging field observations from Bureau of Land Management (BLM) Assessment, Inventory,...

Guy Atlee lived and worked in the Kingman area working the Turquoise mine (Mineral Park) and other mines near Chloride (IXL, Wrigley), Cerbat, and Kingman. He is known to have worked and traveled in the Victorville, Topock and other areas of California. Guy’s wife was Rose Atlee and they had a large family. The collection includes images of mines and workings as well as many images depicting daily life in Mohave County. The photos appear to cover a period from about the turn of the century through the 1920s.

Kelsey Boltz has been a registered mining engineer and geologist in Arizona since the mid 1960s. A 1953 graduate of the Colorado School of Mines, he founded Colamer Corporation and Nuclear Dynamics, both companies active in the uranium industry in the Grants Uranium Region of New Mexico in the '50s, '60s and '70s. In 1981 he co-founded Century Capital, Inc., an investment banking and retail brokerage firm which provided several hundred million dollars financing for various industries including natural resource companies. In 1990 he started his exploration consulting company, Boltz Group International, which initiated and managed several mining projects in Mexico, Chile and Bolivia. The collection consists of geologic...

This collection primarily contains economic geologic information on mines in Mohave County, but also includes more general files on other states and mineral commodities. William Crutchfield, Jr. earned his master's degree from The University of California in 1953. He began working for Santa Fe Mining, Inc. in California in the 1960s as a Mining Engineer and later as Exploration Manager. He stayed with the company until the 1980s.

The Arizona Bureau of Mines (and later the Arizona Bureau of Geology and Mineral Technology and the Arizona Geological Survey) maintained a significant collection of primary data on mining districts, deposits, and prospects across Arizona. Some of this data has previously been utilized to contribute to earlier efforts by the U.S. Geological Survey to develop the Computerized Resources Information Bank (CRIB) as a centralized repository of organizing and summarizing data on mineral resources in the 1970’s. However, the primary data sources have previously only been available in person at the Arizona Geological Survey offices. Following the transfer of the Arizona Geological Survey to the University of Arizona in...
This model archive contains the input data, model code, and model outputs for machine learning models that predict daily non-tidal stream salinity (specific conductance) for a network of 459 modeled stream segements across the Delaware River Basin (DRB). Results are provided for two time periods: the historical drought-of-record from 1965-10-02 to 1969-12-30, and that same drought evaluated in climatic conditions that are consistent with a LENS2 enseble climate projection from 2057-10-02 to 2061-12-30. Results are provided for a total of three Random Forest models, corresponding to three input attribute sets (dynamic attributes, dynamic and static attributes, and dynamic attributes and a minimum set of static attributes)....

The USGS’s FORE-SCE model was used to produce land-use and land-cover (LULC) projections for the conterminous United States. The projections were originally created as part of the "LandCarbon" project, an effort to understand biological carbon sequestration potential in the United States. However, the projections are being used for a wide variety of purposes, including analyses of the effects of landscape change on biodiversity, water quality, and regional weather and climate. The year 1992 served as the baseline for the landscape modeling. The 1992 to 2005 period was considered the historical baseline, with datasets such as the National Land Cover Database (NLCD), USGS Land Cover Trends, and US Department of Agriculture's...

Richard (Dick) Hahman was born in Buffalo, New York, in 1936. He grew up in coal mining towns in Pennsylvania, then later in Washington, D.C. He received his master's in geology from the University of West Virginia. His career took him through the U.S., Canada, Mexico, and Chile. He worked for several companies in Tucson, Arizona, before going to work for Conoco Inc. in Oklahoma City in the early 1980s. In the late '80s he started his consulting company, Hahman & Associates, in Las Cruces, New Mexico. He moved back to Tucson around 1997. The collection contains geologic reports, drill logs, maps, assays, photos and field notes from exploration in Arizona and New Mexico.

The U.S. Geological Survey (USGS) maintains shoreline positions for the United States' coasts from both older sources, such as aerial photographs or topographic surveys, and contemporary sources, such as lidar-point clouds and digital elevation models. These shorelines are compiled and analyzed in the USGS Digital Shoreline Analysis System (DSAS), version 5.1 software to calculate rates of change. Keeping a record of historical shoreline positions is an effective method to monitor change over time, enabling scientists to identify areas most susceptible to erosion or accretion. These data can help coastal managers understand which areas of the coast are vulnerable to change. This data release, and other associated...

Cropland conversion is a leading cause of human modification that threatens the ecological function of the sagebrush (Artemisia spp.) biome – the most intact biome remaining in the conterminous United States. However, despite its prevalence relatively little is known about the extent and risk of cropland conversion as well as the landscape scale benefits of easements in combating cropland conversion. Therefore, our goals were to: 1) quantify the cropland area of the sagebrush biome, 2) identify where the highest quality sagebrush rangelands are most at risk to future cropland, and 3) estimate the ecological benefits of conservation easements to adjacent public lands. Our findings show that croplands span over 14.4...
