Tidal marshes serve as valuable wetlands for many reasons, including fish nurseries, coastal protection, carbon sequestration, and paleoclimatic repositories. Our transect of marsh sites ranges from Jamaica Bay northward to Tivoli Bay, and includes a salinity gradient from marine to fresh. Using both organic and inorganic components of the marsh sediment cores, we analyze fossil pollen and spores, macrofossils, and carbon content to define the history of vegetational change reflecting climate in the Hudson Valley. We see drought during the Medieval Warm Interval and wetter intervals in the Little Ice Age, along with shifts due to disturbance. X-ray fluorescence (XRF) analysis of the sediment reveals the heavy metal pollution history of the last centuries, and help to provide a robust timeline of human impact.

Our Society is once again gearing-up for the festivities of the holiday season with its own Annual Holidays Party. It’s being held on the first Saturday of December (December 2nd), early enough not to interfere with your holiday celebrations later in the month. Also, maybe you can pick up some presents at the party and help the Society’s treasury at the same time!
The party will feature our usual free food and beverages (for members and those guests who are registered), including many specialty foods and desserts. Many books, magazines and other items will be given away free as door prizes - and everybody gets one! There will also be sales tables, copies of our Society’s award winning field guides and publications and free copies of our Newsletters. And thanks to donations by our members, there will be many books on topics in paleontology, geology, dinosaurs and minerals, as well as in anthropology and natural history.
In addition, the events will include educational exhibits, children's events, some brief talks, classic videos with a prehistoric theme, and much more. A more detailed notice will be sent to members.
