Florence Bascom Geoscience Center
Home
The Florence Bascom Geoscience Center (FBGC) is at the leading edge of scientific research addressing critical societal issues and providing unbiased data and information to decision makers and the public. Our research center is built around five broad science themes: Paleoclimate & Paleoecology, Landscape Science, Geologic Mapping, Hazards, and Special Geologic Studies.
Story on Mid-Atlantic Stream/Sediment Science
FBGC's ecologist Greg Noe's work is highlighted in this great article discussing legacy erosion and sedimentation in Mid-Atlantic watersheds.

Memorial to Jack B. Epstein(1935-2020)
Recently, the Florence Bascom Geoscience Center, USGS lost Jack Epstein, a colleague, mentor, and friend. Here is a fitting tribute and memorial to Jack and his nearly 60 years with USGS.
National Preparedness Month 2020: Landslides and Sinkholes
Natural hazards have the potential to impact a majority of Americans every year. USGS science provides part of the foundation for emergency preparedness whenever and wherever disaster strikes.
Floodplain Ecosystem Service Mapper Released
The Floodplain Ecosystem Service Mapper is a web application that displays field site data and lidar-derived floodplain and stream channel geomorphic metrics in the Delaware River and Chesapeake Bay watersheds.

Geologic and mineral map (modified from the 1975 original map compilation by A.S. Shadchinev and others) and hyperspectral surface materials maps of the Ghorband, Salang, and Panjsher River Basins; Kapisa, Panjsher, Parwan, and Baghlan Provinces, Afghanistan
IntroductionThe geologic map and cross sections are a redrafted and modified version of the Geologic map and map of mineral resources of the basins of Ghorband, Salang, and Panjsher; located in the Kapisa, Panjsher, Parwan, and Baghlan Provinces, Afghanistan. The original map and cross sections are contained in an unpublished Soviet report no....

Photoluminescence imaging of whole zircon grains on a petrographic microscope—An underused aide for geochronologic studies
The refractory nature of zircon to temperature and pressure allows even a single zircon grain to preserve a rich history of magmatic, metamorphic, and hydrothermal processes. Isotopic dating of micro-domains exposed in cross-sections of zircon grains allows us to interrogate this history. Unfortunately, our ability to select the zircon grains in a...

Anomalously low winter sea ice extent and early retreat in CE 2018 and 2019 challenge previous notions that winter sea ice in the Bering Sea has been stable over the instrumental record, although long-term records remain limited. Here, we use a record of peat cellulose oxygen isotopes from St. Matthew Island along with isotope-enabled general...
