3D bathymetric surfaces of low- and high-relief sites from the coral reef flat off Waiakane, Molokai, were created using structure-from-motion (SfM) techniques. The two study sites are located approximately 640 m from shore and approximately 20 m apart in the alongshore direction. At each site, an approximate 12-meter diameter area was imaged in three passes by a swimmer using a handheld...

This data release includes 40Ar/39Ar data from the U.S. Geological Survey for samples from the Gidami gold deposit in the Eastern Desert of Egypt. Rock samples were collected by Basem Zoheir--Benha University/University of Kiel. Potassium-bearing mineral grains were separated from the bulk sample and analyzed by argon geochronology at the U.S. Geological Survey Bascom ARgon Dating (BARD)

This data release includes electron 40Ar/39Ar collected at the U.S. Geological Survey for samples from the Day Nui Con Voi metamorphic massif, Vietnam. Rock samples were collected by Meng-Wan Yeh, Michael J. Kunk and Robert P Wintsch in 2011. Mineral separates were prepared and aliquots of amphibole, muscovite, phlogopite, biotite, and potassium feldspar were analyzed by the 40Ar/39Ar...

This data record includes bee species captured by pan trap or hand net in 1-hectare, mixed-grass prairie plots at Badlands National Park, South Dakota, in 2012.

Salinity dynamics in the Delaware Bay estuary are a critical water quality concern as elevated salinity can damage infrastructure and threaten drinking water supplies. Current state-of-the-art modeling approaches use hydrodynamic models, which can produce accurate results but are limited by significant computational costs. We developed a machine learning (ML) model to predict the 250 mg...

This Scientific Data Release is a spatial geodatabase representation of a compilation of Cadwell, D.H., Connally, G.G., Fleisher, P.J., Muller, E.H., 1988, Surficial geologic map of New York; Niagara sheet: New York State Museum Map and Chart Series 40, scale 1:250,000, 5 sheets., Muller, E.H., Cadwell, D.H., Connally, G.G., Young, R.A., 1986, Surficial geologic map of New York; Finger...

Incorporated into USGS OpenFile Report #1094, "The Geologic Classification of the Meteorites", these materials were written by Donald Elston and contain figures, photos, and charts to help astronauts (who were not trained geologists) be able to identify and articulately describe the geologic observations they made on the lunar surface.

To provide a consistent, long-term estimate of discharge from select tributaries to the lower Boise River, two datasets of daily discharge records were harmonized. Differences between a discharge record compiled by the Idaho Department of Water Resources (IDWR) and one compiled by the U.S. Geological Survey (USGS) were computed, and the IDWR record was adjusted so that median discharge...

This model was written in python3 which can simulate water level fluctuations under different drawdown operation rules. We submitted the manuscript about this model to the Journal of Environmental Management. The model file was saved in directory “models/WDLake”, and you can reproduce the results by running the jupyter notebooks in “notebooks/”.

Current models do not sufficiently explain target rock-projectile mixing and ejecta blanket formation for small impact craters (i.e., less than 2km diameter). For example, due to the size of Meteor Crater and the low-velocity at which materials were excavated from the transient crater, the extent of target rock-projectile mixing is expected to be minor. However, based on drilling notes...

This data release contains a 17-year record (2005-2022) of discrete chlorophyll data from inland waters, collected from across the nation and territories. These data are from discrete samples (collected in the field and analyzed in the laboratory) from plankton (suspended algae) and periphyton (benthic algae) from lakes, streams, rivers, reservoirs, canals, and other sites. These data...

Greater sage-grouse (Centrocercus urophasianus) has been identified as a potential umbrella species with the assumption that conservation of their habitats in sagebrush ecosystems may benefit multiple other wildlife species, but co-occurrence with an umbrella species does not necessarily guarantee species will respond positively to management for sage-grouse. This may be particularly...
