Data

The Critical Minerals in Archived Mine Samples Database (CMDB) contains chemistry and geologic information for historic ore and ore-related rock samples from mineral deposits in the United States. In addition, the database contains samples from archetypal deposits from 27 other countries in North America, South America, Asia, Africa and Europe. Samples were obtained from archived ore collections u

Dataset includes site averages of measurements of floodplain and streambank sediment physico-chemistry and long-term (dendrogeomorphic) vertical and lateral geomorphic change, and reach scale floodplain width, streambank height, channel width, and streambed particle size. This information was used to calculate fluxes of sediment, fine sediment, sediment-C, sediment-N, and sediment-C of floodplains

This data release supports the manuscript: Walker, R.H. and A.W. Walters. 2019. A mechanistic understanding of ecological responses to anthropogenic surface disturbance in headwater streams. Ecosphere 10(10):e02907. 10.1002/ecs2.2907. It includes one data set with physicochemical and biological data from 40 stream sites (100 m length) in the Wyoming Range for summer 2016.

The datasets stored in this folder summarize reproductive data for Brown Pelicans nesting on Gaillard and Cat Islands, Alabama, in 2017 and 2018. Data include nest and nestling survival, nest site characteristics, environmental covariates, and temperatures recorded inside nests.

Mass-wasting events that displace water, whether they initiate from underwater sources (submarine landslides) or subaerial sources (subaerial-to-submarine landslides), have the potential to cause tsunami waves that can pose a significant threat to human life and infrastructure in coastal areas (for example towns, cruise ships, bridges, oil platforms, and communication lines). Sheltered inlets and

This dataset accompanies planned publication 'Genesis of early Neoproterozoic gold deposits, southwestern Amazon Craton, western Brazil'. The Ar/Ar data is for samples that record the mineralization of the area. The geochronology provides time constraints for the mineralization studied in the manuscript. Samples were collected from the Amazon Craton region, and collection was done by Rodrigo Prude

This dataset accompanies planned publication 'Gondwanan inheritance on the building of the western Central Andes (Domeyko Range, Chile): Structural and thermochronological approach (U-Pb and 40Ar-39Ar)'. The Ar/Ar data is for samples that record the sedimentation of the area. The geochronology provides time constraints for the sedimentation studied in the manuscript. Samples were collected from th

The dryland ecosystems of the western United States have been invaded by exotic annual grasses, such as cheatgrass (Bromus tectorum L.), that has promoted increased fire activity and reduced biodiversity detrimental to socio-environmental systems. The use of remote sensing tools to monitor exotic annual grass cover and dynamics over large areas can support early detection and rapid response initia

These data present the results of sediment toxicity tests conducted by the US Geological Survey's Columbia Environmental Research Center (CERC) in Columbia, MO, in 2014. The sediments were collected as one part of a larger study on stream quality in Southeastern USA streams during the summer of 2014. For more information on the larger study see- https://webapps.usgs.gov/rsqa. The data include resu

Detailed data collected from the field and generated during diagnostic evaluation of whooping crane carcasses from the Eastern Migratory Population.

Data included in this release are from Pacific sand lance and water, sediment and suspended particulate matter collected at two sites in Puget Sound, Washington, which were evaluated for PCB concentration. PCB congener data are stored in the U.S. Fish and Wildlife Service's Environmental Contaminant Data Management System (ECDMS), accessible through the Wildlife & Environmental Contaminants Mapper
