Holocene and Modern Drivers of Wetland Change
On a global scale, wetland systems have been affected by climate extremes, changing sea level, and population growth, reducing their capacity to moderate storm surge, filter contaminants, store carbon, and provide habitats for fish and wildlife. This research takes a long-term perspective on the resilience of wetlands to a range of climatic and human-induced changes and provides critical data to...
Wetlands in the Quaternary
Wetlands accumulate organic-rich sediment or peat stratigraphically, making them great archives of past environmental change. Wetlands also act as hydrologic buffers on the landscape and are important to global biogeochemical cycling. This project uses wetland archives from a range of environments to better understand how vegetation, hydrology, and hydroclimate has changed on decadal to multi...

Acetolysis Set-Up, Pollen Laboratory
Seen in this image is the acetolysis set up. Acetolysis is used to remove the genetic material from inside the pollen, which allows the scientists to better identify and count the pollen.

Pollen Under a Microscope
This image was taken through the eyepiece of a microscope. Pollen is mixed in with a few larger pieces of organic material.

Great Dismal Swamp Burn Area, March 2017
USGS scientists recently collected peat and lake core samples from the swamp to help reconstruct natural, environmental conditions over the past 12,000 years.
