Detailed Description

This video explains how scientists from the Florence Bascom Geoscience Center research paleo-environmental wetland conditions and explain how studying these environments is valuable to better understand past changes and responses to disturbance, such as fire, sea-level rise, and permafrost degradation.  The USGS 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.

Transcript

>> Coming to work every day is exciting because we sort of get to act as detectives.  We get to play in the mud and discover new worlds that I think most people probably don't even know exist.  Some of the tools we use, starting in the field, we take cores.  The wetland sediments are great archives because there's limited oxygen, and so things don't decompose.  Each centimeter accumulates with time, and so when we cut each core, we can then reconstruct those changes that have happened through time.  What the paleo record can tell us is what did this wetland look like prior to human intervention?  And what can we help the policymakers understand about the ecosystem that can help them manage it better?
