Detailed Description

This video introduces research that Florence Bascom Geoscience Center (FBGC) scientists are conducting on the 500,000 year history of Arctic sea ice to assess changes in weather, sea ice extent, temperature and ecosystems. The research informs decision makers on issues ranging from ecosystems and endangered species to transportation, energy policy, and national security. 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.

>> The Arctic is one of the most inhospitable places.  Most of the year, it's socked in by sea ice.  Water temperatures are frigid, so we have a really short window of time to collect sediments and take measurements.  In our research, we really utilize marine sediment cores.  We'll look at really small organisms that we find, and they secrete a calcareous shell that gets preserved in the ocean sediments.  When we find changes in the species, we can infer different environmental conditions at the time that they were living.  The Arctic region is experiencing enormous changes.  The data that our science center creates helps decision-makers make better choices for our life, our environment, and our future.
