Groundwater Staining in Pennsylvanian Sandstone, West Virginia
Fractures in bedrock transmit groundwater, and geologic mapping is conducted to provide the geologic framework for groundwater resource studies. This photo shows iron-oxide staining (Leisegang banding) from past groundwater flow along fractures formed prior to the rock having been blasted open during road construction.

Measuring index properties on sediment samples
Junbong Jang of the USGS Woods Hole Coastal and Marine Science Center measures index properties on sediment collected during the Indian Government’s National Gas Hydrates Program (NGHP-02) drilling expedition offshore from eastern India in the summer of 2015.

Sea-level rise effects vary in geomorphology and ecology
The effects of sea-level rise will vary by differences in the geomorphology and ecology of the landscape. Images show marsh (top left) rocky coast (top right), barrier beach (bottom left), and coastal bluff (bottom right)

Coastal Response Predictions
Map showing extent and coverage of coastal response type predictions; insets display different prediction types and geospatial variability through time. Predictions of coastal response likelihood for the four prediction time steps at Blackwater National Wildlife Refuge, VA.

USGS scientist collects samples in a New Jersey salt marsh
Caption: USGS scientist Zafer Defne measures water and sediment movement at Forsythe National Wildlife Refuge, New Jersey. Defne is co-author with USGS' Neil Ganju of a 2017 study on how to estimate coastal salt marshes' potential longevity, based on their sediment budgets and the ratio of open water to vegetation.
