The Big Impact of Little People: Past Environment and Climate of the Hudson Estuary
Tuesday November 17th
Room 417 Schermerhorn Hall
Summary: It has been 400 years since Henry Hudson led the European discovery of the Hudson River, but the Hudson has been the heart of New York region since long before then. What was it like before European settlement? How has the environment along the estuary changed over the past millennium? How do scientists uncover the past ecosystem and understand the climate of the estuary?
Sanpisa Sritrairat is a Ph.D. student in the department of Earth and environmental sciences, whose general fields of interest are Paleo-ecology, paleoclimate, wetlands biogeochemistry, and environmental geochemistry. More specifically, she examines cores from the Hudson River marshes for changes during the last millennium using pollens, macrofossils, and geochemical tracers. She is working with Adjunct Associate Professor Dr. Dorothy Peteet to identify ecological changes based on pollens, spore, and macrofossils, LOI, and C13 and N15 stable isotopes signatures. Not only can these paleo-records capture climate changes, anthropogenic effects on ecosystem, such as the deforestation during the European settlement and the spreading of introduced species, can also be observed. Her Ph.D. work incorporates a variety of tools to unveil paleo-environment, paleo-carbon, nutrients dynamic, and toxic-metal contamination in these wetlands.
Sanpisa received a dual B.S. in Biology and Hydrogeology from Rensselaer Polytechnique Institute in 2004.
Future talks are scheduled for Tuesdays from 12:15-1:00pm in Room 417 Schermerhorn Hall. Attendees are welcome to bring their lunch.
All are welcome to attend!
