Marie R Champagne

Marie is a Physcial Science Tech in the Geology, Minerals, Energy, and Geophysics Science Center in Menlo Park, CA. She works in the Quaternary Paleoenvironmental Research Laboratory. She focuses on optimizing pollen preparation techniques, pollen counting, general wet lab work, microfossil preparation, isotope analysis, age-depth chronologies, and lab organization and safety.

Marie Champagne first became interested in paleoclimate research at UC Berkeley. She worked with Dr. Roger Byrne on many projects focusing on the climate history of lakes. Since joining USGS as a technician, she has assisted Dave Wahl and Lysanna Anderson with various paleoecological studies.

Drivers and Impacts of North Pacific Climate Variability

Climate model forecasts indicate an increase in extreme hydrologic events, including floods and droughts, for California and the western U.S. in the future. To better understand what the consequences of this future change in climate may be, USGS scientists are studying the frequency, magnitude, and impacts of past hydroclimate variability and extremes in the region. This project produces well...

Linking modern pollen accumulation rates to biomass: Quantitative vegetation reconstruction in the western Klamath Mountains, NW California, USA

Quantitative reconstructions of vegetation abundance from sediment-derived pollen systems provide unique insights into past ecological conditions. Recently, the use of pollen accumulation rates (PAR, grains cm−2 year−1) has shown promise as a bioproxy for plant abundance. However, successfully reconstructing region-specific vegetation dynamics using PAR requires that accurate assessments of pollen
