Earth’s Past and Future

To improve forecasts of future sea level rise, scientists study coastlines that have preserved geologic markers of where sea levels were during past times. In 2022, paleoclimatologists Billy D’Andrea, Blake Dyer, Oana Dumitru, Roger Creel, and Steve Goldstein sampled and measured coral and rock formations along coastlines in the Turks and Caicos Islands. Their focus: the last interglacial period about 120,000 years ago when temperatures were close to what is projected for later this century, at which time seas may have risen precipitously. 📷 Waves off the Atlantic Ocean slowly take fossilized carbonate dunes back to sea in Middle Caicos, Turks & Caicos Islands, June 2022.

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.

How Can AI Address Climate Justice When Women’s Voices Are Silenced?

Unless women’s lived realities are embedded in AI's foundations, it risks reinforcing the very inequities it claims to solve.

Events

Earth Observations: Conversations with Lamont Scientists

On March 25 6-8pm ET, join us for our next Public Lecture, Climate and Ice: From Rising Seas to Shrinking Mountain Glaciers, with Lamont-Doherty Earth Observatory geochemist Joerg Schaefer who will explore how fast ice is melting, where it is changing most rapidly, and how we can respond to these challenges. Hosted by Lamont interim director Steven L. Goldstein, this in-person event begins with a reception from 6-7pm ET followed by the discussion from 7-8pm ET. Learn More/RSVP

  • Paradise featuring oil paintings by Selva Ozelli and photographs by Ian Hutton (Lamont Café through June 30, 2026)

  • Climate Disasters Inspired by Great Masters featuring works by Palisades, NY artist Mary Tiegreen in collaboration with BingAI for Climate Change Resources (Monell Building through June 30, 2026)

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. Community science programs, school education, and special events continue throughout the year, however, Field Station drop-in hours ended in October for the off-season, and will re-start in late May/early June. Our many educational resources and all our sampling data are regularly updated and always available on the Field Station website! Questions about our community science programs, school and group education programs, or upcoming events at the Lamont-Doherty Hudson River Field Station? Contact Marisa Annunziato.

Phytoplankton underneath microscope

Plankton are microscopic organisms that can be found in the world's oceans, lakes, estuaries, and rivers. Though small, they play a massive role in the Earth's ecosystem. Phytoplankton and zooplankton act as an important food source for many crustaceans and species of fish, including menhaden, herring, bay anchovies, etc., in the Hudson Estuary. Seasonal blooms of plankton in the lower reaches of the estuary marks the beginning of spring. Check out our plankton ID guide to learn more about the plankton in the Hudson Estuary, and consider getting involved in our community science plankton survey.

Our community science projects are starting back up in March, and we have many different opportunities for you to be involved! Among the many benefits of participating are learning more about local research, being part of a science community, building an appreciation for the natural environment, working outdoors conducting field work, and for high schoolers, gaining community service hours. Programs include oyster monitoring, fish diversity and abundance, microplastic survey, plankton survey, marine debris survey, and water quality monitoring. We will be launching a brand new community science project focused on water birds this spring! Contact Marisa Annunziato to get involved!

 

Education

Lamont educators engaging with youth about polar topics at Intrepid Kids Week

Our education team is out in the community this spring. There are multiple opportunities to catch up with us, so please come and visit!

In February, we spent two busy days participating in Science and Nature Days during Intrepid Museum Kids Week, visited by nearly 6,000 people!  

In March, we have more planned events:

  • On Saturday March 14 11am-3pm, we will be part of Girls in Science & Engineering Day at the Intrepid Museum. This is a family-focused event with a special focus on girls! Pre-register for free access to the museum and event.

  • On Saturday March 21 8:30am-12:45pm, we will participate in the annual Rockland Girls Rock STEAM as part of their community connections session. This event is for girls grades 5-8. Participants must pre-register.

  • Sunday March 29 11am-3pm is the Rockland YouthFest at Rockland Community College, a free, fun, family-friendly event!
