Florence Bascom Geoscience Center
The primary mission of the Florence Bascom Geoscience Center (FBGC) is to provide detailed scientific data and assessments to support natural resource management, public safety, and national security. The FBGC specializes in:
Geologic mapping and hazards
Paleontology, stratigraphy, and environmental geology
Special geologic studies at the intersection of national security and mineral resources

Ecological thresholds and transformations due to climate change: The role of abiotic stress
An ecological threshold is the point at which a comparatively small environmental change triggers an abrupt and disproportionately large ecological response. In the face of accelerating climate change, there is concern that abrupt ecosystem transformations will become more widespread as critical ecological thresholds are crossed. There has been ongoing debate, however, regarding the...

Nanometer-scale relationships between sedimentary organic matter molecular composition, fluorescence, cathodoluminescence, and reflectance: The importance of oxygen content at low thermal maturities
Molecular characterization of sedimentary organic matter (SOM), termed macerals, is a common goal when seeking to understand petroleum generation as well as other geologic processes in deep time. However, unambiguous measurement of discrete macerals is challenging due to the small size of organic particles in sedimentary rocks, the proximity of different organic matter types to one...
Properties of solid bitumen formed during hydrous, anhydrous, and brine pyrolysis of oil shale: Implications for solid bitumen reflectance in source-rock reservoirs
Solid bitumen reflectance (BRo in %) is widely used as a thermal maturity proxy in source-rock reservoirs, yet solid bitumen texture and physical attributes may be affected by varying environmental constraints during its formation, e.g., water saturation, mineral catalysis, or salinity. Herein we investigated the development of solid bitumen properties during artificial maturation using...

Coastal Wetland Vulnerability to Climate Change and Sea-Level Rise: Understanding Ecological Thresholds and Ecosystem Transformations
Eighteen USGS coastal scientists from all four coasts of the conterminous United States are working together to advance the understanding of climate change and sea-level rise impacts to coastal wetlands.

Quaternary Geologic Mapping of the Glaciated Regions Project
Task 3 - Geologic Mapping of the (other) Non-Coalition Glaciated States
The area encompassed by Task 3 comprises the non-coalition (other) states within the glaciated region, including Montana, North Dakota, South Dakota, Iowa, Kansas, Missouri, Nebraska, and New Jersey. The primary objective of Task 3 is to continue the compilation of existing and create new 1:500,000-scale Quaternary geologic maps for the region, and to conduct new 1:24,000-scale mapping in areas of...
