At recent technical conferences, many coal geoscientists in academia and government institutions as well as in industry organizations have expressed concern about the dwindling number of students and young staff members interested in careers in coal geoscience. To better understand what is driving these trends and to identify potential ways that the community can increase interest and participation in coal geoscience, two different surveys were sent to 94 coal geoscientists who were current or past members of The Society of Organic Petrology (TSOP) in February 2020. As the trends and perceptions in industry and government organizations may be different than in universities, one distinct survey was sent to members...
This child data release includes hyperspectral and RGB images acquired from an Unmanned Aircraft System (UAS) during an experiment performed at the USGS Columbia Environmental Research Center, near Columbia, Missouri, on April 2, 2019. The purpose of the experiment was to assess the feasibility of inferring concentrations of a visible dye (Rhodamine WT) tracer from various types of remotely sensed data in water with varying levels of turbidity. Whereas previous research on remote sensing of tracer dye concentrations has focused on clear-flowing streams, the Missouri River is much more turbid and the reflectance signal associated with the sediment-laden water could obscure that related to the presence and amount...

Understanding the effects of fungicides on non-target organisms at realistic concentrations and exposure durations is vital for determining potential impacts on aquatic ecosystems. Environmental concentrations of the fungicide azoxystrobin have been reported up to 4.6µg/L in the United States and 30 µg/L in Europe. The objective of the present study was to evaluate the chronic toxicity of azoxystrobin in water-only exposures with an amphipod (Hyalella azteca; 42-d exposure), a midge (Chironomus dilutus; 50-d exposure), a cladoceran (Ceriodaphnia dubia; 7-d exposure), and a unionid mussel (Lampsilis siliquoidea; 28-d exposure) at environmentally relevant concentrations. The potential photo-enhanced toxicity of azoxystrobin...
This child data release includes RGB (red-green-blue) videos acquired from an Unmanned Aircraft System (UAS) during a tracer experiment performed on the Missouri River near Columbia, Missouri, on May 5, 2021. One of the primary goals of this tracer experiment was to assess the feasibility of inferring concentrations of a visible dye (Rhodamine WT) from various types of remotely sensed data in a large, highly turbid natural river channel. Previous research on remote sensing of tracer dye concentrations has focused on clear-flowing streams, but the Missouri River is much more turbid. As a result, the effect of the dye on the reflectance of the water could be obscured by the effects of suspended sediment on reflectance....

South America is part of Region 6 (Central and South America) for the World Energy Assessment. South America was divided into 107 geologic provinces as background for prioritization and assessment of undiscovered oil and gas resources. The boundaries of geologic provinces are required for the assessment as oil and gas. Data must be allocated to a geographic entity so that decisions can be made as to which provinces are priority for the assessment. Many sources of geologic information were used to define the province boundaries in South America, and several versions of the map were reviewed. Of the 107 geologic provinces defined in South America, about 40 have had some oil and gas production to date.

This inventory was originally created by Garcia-Delgado and others (2019) describing the landslides triggered by the M 5.7 Mesetas, Columbia earthquake that occurred on 24 December 2019 at 19:19:03 UTC. Care should be taken when comparing with other inventories because different authors use different mapping techniques. This inventory also could be associated with other earthquakes such as aftershocks or triggered events. Please check the author methods summary and the original data source for more information on these details and to confirm the viability of this inventory for your specific use. With the exception of the data from USGS sources, the inventory data and associated metadata were not acquired by the...

As a result of a Latin American Coal Assessment, the USGS published the first Coal Map of South America (Weaver and Wood, 1994) and developed a cooperative inter-American exchange of geologic information which lead to a better understanding of the potential for coal resource utilization in the western hemisphere. This coal study was started by the late Gordon H. Wood, Jr. The original compilation, completed before his death, was a result of library research and it did not include updated information from scientists and others in the coal-bearing countries of South America. During the Fall of 1991, Jean N. Weaver visited Uruguay, Argentina, Chile, Peru, Ecuador, Colombia, Venezuela, Brazil, and Bolivia. The purpose...
South America is part of Region 6 (Central and South America) for the World Energy Assessment. The geologic map of South America was digitized so that we could use the geology as a general guide to draw the boundaries of the geologic provinces of South America.

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over Columbia, South Carolina, and the surrounding region. The airborne data collection was funded by the U.S. Geological Survey (USGS) Earth Mapping Resource Initiative (Earth MRI) with goals of better understanding placer deposits containing critical mineral resources titanium, zirconium, and rare earth elements and of imaging the crystalline basement partly buried beneath Atlantic Coastal Plain sediments. The survey was flown northwest of and slightly overlapping an airborne magnetic and radiometric survey collected in 2019 (Shah, 2020). The northwestern boundary of the 2020 survey lies within the...
