Image scans of feathers collected from 2006-2019. Naming convention for each photo is species code_band number_year. If more than one photo was taken of a given photo type, a unique letter was added to the end of the photo description.The data providers have invested considerable effort in QA/QC, but it is possible that undetected errors remain. It is strongly recommended that careful attention be paid to the contents of the metadata file associated with these data to evaluate data set limitations, restrictions, or intended use.

This collection contains files associated with data analysis of Dunlin brood survival found in Saalfeld, S.T., B.L. Hill, C.M. Hunter, C.J. Frost, and R.B. Lanctot. 2021. Warming Arctic summers unlikely to increase productivity of shorebirds through renesting. Nature Scientific Reports 11:15277.Directories include: input_files, output_files, R_code, program_mark_files, and figure_files. Found in the analysis_output folder on the RDR.Information for the Dunlin brood survival project were obtained concurrently with information obtained for the Utqiagvik shorebird project and information on chicks and nests included in these files may also be contained within the Utqiagvik shorebird project archive (file://ifw7ro-file.fws.doi.net/datamgt/mbm/mbmsh_009_Utqiagvik_shorebird_project).Th...

This data release includes grids representing the depth and thickness of drinking-water withdrawal zones, polygons of hydrogeologic settings, an inventory of sources of well construction data, and summaries of data comparisons used to assess the depth of groundwater used for drinking-water supplies in the United States. Well construction data sources are documented in Table1_DataSources.xlsx. Data comparisons using the Mann-Whitney test to assess similarity between hydrogeologic settings were used to justify combining data where they were sparse (compare_neighbors_all_domestic.txt and compare_neighbors_all_public.txt). Water-supply-well depth varies geographically by water use and the type of well, which illustrates...

Beginning in 2003, we have conducted a long-term shorebird breeding ecology study at Utqiaġvik (formerly Barrow), Alaska. The objectives of this study are to (1) collect baseline data on temporal and spatial variability of shorebird diversity and abundance, (2) collect information on nest initiation and effort, replacement clutch laying, clutch and egg size, nest and chick survival, and other demographic traits of Arctic-breeding shorebirds, (3) establish a marked population of as many shorebird species as possible that will allow us to estimate adult survival, mate and site fidelity, and natal philopatry, and (4) relate weather, food availability, and predator and prey abundances to shorebird productivity and survival....

Information on abundance, distribution, chronology, and habitat associations of birds at U.S. Air Force Long Range Radar Sites (USAF LRRS) and U.S. Navy lands is either outdated or lacking. In other situations, existing information has been obtained using a variety of incompatible methods thereby complicating the ability to discern changes to bird communities or the habitats they rely upon. Up-to-date information on the use of military lands by all bird species is important for both the Department of Defense (DOD) and the U.S. Fish and Wildlife Service (USFWS). Furthermore, updating avian inventories and implementing a standardized monitoring program across military lands helps USFWS-MBM by improving avian trend...

The degradation of critical wintering and migratory stop-over sites is known to have direct consequences on the survival and reproductive condition of migratory shorebirds. However, little is known about migratory movements and connectivity of shorebird populations. By identifying migratory stop-over and wintering areas, we can begin to identify sites that should be conserved and evaluate the relative risks of development and climate change scenarios. Beginning in 2017, we initiated a project to track the migration movements of shorebird species using Argos, GPS, and Pinpoint tags. The primary objective of this study is to collect baseline information on movement patterns of shorebirds during the post-breeding period...

These datasets describe the inventory of feather and blood samples collected from shorebirds that were captured primarily in northern Alaska but also in other parts of the world where studies were conducted on migratory species that breed in Alaska. These samples are maintained by USFWS and the feather samples in particular are part of the AviSample Network metadata repository (see Brlik et al. 2022. The reuse of avian samples: opportunities, pitfalls, and a solution. Ibis 164:343-349).Additional information for samples collected at Utqiagvik and in association with the tracking project can be found in the Utqiagvik shorebird project (file://ifw7ro-file.fws.doi.net/datamgt/mbm/mbmsh_009_Utqiagvik_shorebird_project)...

This data release provides water-quality trends for rivers and streams in the Delaware River Basin determined using the Weighted Regressions on Time, Discharge, and Season (WRTDS) model and the Seasonal Kendall Trend (SKT) test. Sixteen water-quality parameters were assessed, including nutrients (ammonia, nitrate, filtered orthophosphate, total nitrogen, total phosphorus, and unfiltered orthophosphate), major ions (calcium, chloride, magnesium, potassium, sodium, and sulfate), salinity indicators (total dissolved solids and specific conductance), and sediment (total suspended solids and suspended sediment concentration). The child items include the input and output data used in the modeling and testing of water-quality...

The Spoon-billed Sandpiper (Eurynorhynchus pygmeus) is a critically endangered species (Bird Life International 2011) with a population estimated at 661-678 individuals (but only 210-228 breeding pairs, Clark et al. 2016). Although it principally breeds in Russia and has not officially been documented breeding in Alaska, observations of Spoon-billed Sandpipers have been recorded in Alaska during the breeding season (Kessel and Gibson 1978), and a recently developed habitat suitability model indicated that suitable nesting habitat occurs in Alaska’s Chukchi Sea region (RSBP 2012). However, no systematic survey of potential breeding habitat had been conducted in this region during the spring and summer when this species...

In 2008 and 2009, we investigated the survival of chicks from initial and experimentally-induced replacement nests of arcticola Dunlin (Calidris alpina) breeding near Utqiaġvik, Alaska. We monitored survival of 66 broods from 41 initial and 25 replacement nests. See Saalfeld, S.T., B.L. Hill, C.M. Hunter, C.J. Frost, and R.B. Lanctot. 2021. Warming Arctic summers unlikely to increase productivity of shorebirds through renesting.

The USGS Shoemaker collection is composed of impact crater rocks from Meteor Crater (AZ), Flynn Creek Crater (TN), Sierra Madera Crater (TX), Steinheim Crater (Germany), and several craters in Australia. Of special interest to planetary science are nine bags of fallback ejecta from the Meteor Crater interior. Also in the collection are igneous, sedimentary, and metamorphic rocks from South Africa, Australia, the San Francisco Volcanic Field, the Colorado Plateau, and many other locations throughout the U.S. The USGS Shoemaker Collection is an essential part of the legacy of Dr. Eugene Shoemaker, whose pioneering work in the 1960’s established the new field of astrogeology, including shock metamorphism studies, impact...

A three-dimensional groundwater flow model, MODFLOW 6, was developed to provide a better understanding of the hydrogeology of the Harney Basin, southeastern Oregon. The model was used to investigate the historical groundwater-level decline and storage loss associated with anthropogenic groundwater demands. The model was calibrated to 1930 through 2018 conditions. This USGS data release contains all of the input and output files for the simulation described in the associated model documentation report (https://doi.org/10.3133/sir20241518)
