Florence Bascom Geoscience Center

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.

USGS Scientists Help Address Conflict Mining

Artisanal miners digging a mining pit using simple tools such as shovels, buckets and water pumps.

The USGS has collaborated with several international organizations working to track and monitor illegal mining and armed groups funded by natural resources around the world.

Preliminary map of the surface rupture from the August 9, 2020, Mw 5.1 earthquake near Sparta, North Carolina—The Little River fault and other possible coseismic features

This publication is a preliminary map and geodatabase of the coseismic surface rupture and other coseismic features generated from the August 9, 2020, Mw 5.1 earthquake near Sparta, North Carolina. Geologic mapping facilitated by analysis of post-earthquake quality level 0 to 1 lidar, document the coseismic surface rupture, named the Little River fault, and other coseismic features.

Implementation plan of the National Cooperative Geologic Mapping Program strategy—Northeast region of the United States: New York and New England

Complexly deformed igneous, metamorphic, and sedimentary rocks form the bedrock of the Northeast region of the United States. Variably thick unconsolidated sediments deposited by glacial, fluvial, and eolian systems locally cover the bedrock. New geologic mapping focuses on areas lacking modern, detailed studies or syntheses, and contributes to existing framework research. This report addresses pl

Early Pliocene (Zanclean) stratigraphic framework for PRISM5/PlioMIP3 time slices

Global reconstructions of Pliocene climate provide important insights into how the climate system operates under elevated temperatures and atmospheric CO2 levels. These reconstructions have been used extensively in paleoclimate modeling experiments for comparison to simulated conditions, and as boundary conditions.Most previous work focused on the Late Pliocene interval known as the mid Piacenzian

New study shows importance of streambank erosion and floodplain deposition on sediment, phosphorus, and nitrogen sources and transport in the Chesapeake watershed

Issue: As Chesapeake Bay Program partners work to reduce pollution, knowing sources of sediment, phosphorus, and nitrogen transported to the Bay is critical for effective and efficient management. Streams and their associated floodplains have an important influence on the transport of nutrients and sediment through the Chesapeake watershed and into tidal waters. The USGS is conducting...

New Review of Sediment Science Informs Choices of Management Actions in the Chesapeake

Issue: The Chesapeake Bay Program (CBP) is pursuing restoration efforts to improve habitats and associated water quality for fisheries, both in the watershed and estuary. Excess sediment decreases light in tidal waters for submerged aquatic vegetation, harms oysters, carries contaminants, and impairs stream health throughout the watershed. The CBP is implementing management actions and policies...
