This data release contains the U.S. salient statistics and world production data extracted from the GYPSUM data sheet of the USGS Mineral Commodity Summaries 2023.
The data presented include concentrations of 122 organic, 23 inorganic constituents, and estrogenicity in water collected from 13 off-stream non-point source sites (natural and created wetlands) and eight on-stream point source sites (streams and impoundments) in the New Jersey Pinelands, 2017-2020. Native and non-native fish health data collected from the on-stream sites as well as native frog data collected from the off-stream sites are also included. For the on-stream point-source component, we analyzed water chemistry, hormone activity, and collected native and non-native fish from two locations upstream and one downstream from two municipal wastewater treatment plants (six total sites) and from two minimally...
This dataset provides seven Sentinel-1 Synthetic Aperture Radar (SAR) scenes covering a portion of the Madeira River in Brazil from Porto Velho to Abuna. Each scene has been pre-processed for the use of detecting artisanal and small-scale mining (ASM) riverine dredges. The scenes were collected from the ASF search vertex (https://search.asf.alaska.edu/#/) as L1 Detected High-Res Dual-Pol (GRD-HD) products. They were acquired using a C-band SAR with the Interferometric Wide Swath (IW) mode, VV and VH polarizations, and a temporal resolution of 6 days. Each SAR acquisition covers a 250 km swath; however, these have been clipped to the study area. They have a 20 m x 22 m (ground range x azimuth) resolution, a 10 m...

Cave and Karst Biota Modeling in the Appalachian LCC - Observed troglobiotic fish in 20km grid cells
We developed spatial summary (GIS) layers for a study of factors influencing the distribution of cave and karst associated fauna within the Appalachian Landscape Conservation Cooperative region, one of 22 public-private partnerships established by the United States Fish and Wildlife Service to aid in developing landscape scale solutions to conservation problems (https://lccnetwork.org/lcc/appalachian). We gathered occurrence data on cave-limited terrestrial and aquatic troglobiotic species from a variety of sources within the Appalachian LCC region covering portions of 15 states. Occurrence records were developed from the scientific literature, existing biodiversity databases, personal records of the authors, museum...

This metadata record document contains 7 tables used to assess factors influencing long-term water quality changes in the Gwynns Falls, Baltimore, MD, 1998-2016. Included are daily discharge measurements (source: United States Geological Survey (USGS), 2016), weekly nutrient sampling concentrations (source: Baltimore Ecosystem Study (BES), 2015), and approximately monthly bacteria, ammonia, TKN, and TSS sampling concentrations (source: Baltimore City Department of Public Works (DPW), 2016; Baltimore County Department of Environmental Protection and Sustainability (DEPS), 2016). Annual loads were calculated for each Gwynns Falls subwatershed from the discharge measurements and sampling concentrations. Green infrastructure...

Proppants used during hydraulic fracturing of oil and gas wells are manufactured to maximize petroleum yield by controlling the size, shape, density, and strength of the proppant material. The most common types of proppants are mined silica sand and manufactured ceramics, some of which are further modified with organic resin coatings to improve performance. Much of the work on the environmental and human health effects of proppant releases into the environment has focused on occupational silicosis, with little attention given to the potential effects from the organic coatings on these materials. This oversight is especially relevant in the context of dumping of unwanted proppant on the land surface, which has been...

U. S. Geological Survey (USGS) scientists completed a stream surveying campaign from the 26th of July to the 13th of August in 2021 at thirty 100m reaches within the Shenandoah Valley throughout Virginia and West Virginia. The goal was to collect three cross sections, water surface elevation at the top and bottom of each reach, and thalweg point data at each study location to use the geomorphological surveys alongside habitat information. Together, these two sources of data can be used to create a habitat assessment of Shenandoah Valley streams. Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government.
