Opening Doors for Science

As American science faces cuts in research funding, your support is more important than ever. By making a gift to Lamont-Doherty Earth Observatory today, you help advance our mission, strengthen our community of researchers, and expand our education and outreach initiatives—ensuring that Lamont continues to push the boundaries of scientific discovery. At a time when research funding is increasingly uncertain, your support is more important than ever. Every dollar donated stays at Lamont, supporting Lamont science and scientists.

Mark your calendar! Columbia Giving Day is Wednesday, October 28, 2026. Last year, you helped Lamont-Doherty weather serious threats to scientific funding and rescue critical research projects that would have otherwise been in jeopardy. Now, we ask that you help us sustain those projects. Our scientists remain committed to addressing some of society's greatest challenges, including the mysteries surrounding prolonged drought, the environmental impacts of microplastics, and rising sea levels. Provide immediate support for Lamont science by making a gift to the Lamont Director's Unrestricted Research Fund on Columbia Giving Day. Your contribution will be matched dollar-for-dollar up to $50,000 thanks to the generosity of an anonymous supporter!

On display at Lamont-Doherty Earth Observatory are three fascinating art exhibits:

• Research as Art featuring works by Lamont researchers (Monell Building)

• Flags of Science CCL by Selva Ozelli (Lamont Café through June 30, 2027)

• Whimsical Science by Betsy Franco-Feeney (Monell Building through May 31, 2027)

Contact Miriam Cinquegrana for more information/appointments.

Lamont-Doherty Hudson River Field Station

We are located at 200 Ferry Road, Piermont, NY at the eastern end of Rockland County's Piermont Pier. The Field Station will be closed to public drop-ins starting in mid-October for the off-season, but don’t worry: we offer community science programs for the public to get involved in the work that we do year-round!

Our many educational resources and all our sampling data are regularly updated and always available on the Field Station website! Questions about our school and group education programs or upcoming events at the Lamont-Doherty Hudson River Field Station? Contact Marisa Annunziato.

Education

Join Our Polar CAP Interns at the Sustainability Walk & Fair, Congers Lake

On Sunday October 4, our Polar Climate Ambassadors will be hosting a table at the 6th Annual Sustainability Walk & Fair with some hands-on crafts and information about some of the Arctic communities they learned about over the summer. Attendees will be introduced to the important values of the Inupiaq community, make a beaded Snowy Owl hanging to take home, and hear how this incredibly beautiful bird is under threat from climate change. Snowy Owls (or ukpik in Inupiaq) are deeply linked to the Inupiaq culture and history, symbolizing wisdom, guidance, and protection. Join us!

Climate LIVE K12 features live lectures and interactive activities with our scientists and experts for K-12 students, educators, families, and the public! FREE!  Check out our rich YouTube archive of all past workshops.

Up Next: On October 14, 4-4:30pm ET, join a Columbia Climate School Pre-College alum for A Blooming Problem: Researching Solutions to Harmful Algal Blooms. In this session, students will meet a high school researcher investigating innovative ways to understand, prevent, and mitigate algal blooms. Follow the research journey as they explore how scientists turn a real-world environmental problem into a research question, design experiments, navigate unexpected results, and work toward potential solutions. RSVP today (free but registration required)!
