Open House

Shortly after Lamont-Doherty Earth Observatory was founded in 1949, its founder, Maurice “Doc” Ewing, realized that Lamont’s neighbors were not aware of the nature of the research conducted here. Therefore he started Open House, and opened up the campus one day each year for neighbors, students and the wider Columbia University community.

In 1999, in recognition of Lamont’s 50th Anniversary, Open House was expanded to include nearly 40 exhibits, lectures and demonstrations, and attracted over 4,000 people. Attendees learn about the current developments in the Earth Sciences, and about how our increasing understanding of the Earth helps preserve it future. Different exhibits are aimed at different ages and educational levels, from elementary school-age children to college students to those well versed in the earth sciences.

Open House is typically held the first Saturday in October. Find out about  this year's event.

Public Lectures

The Public Lectures series was begun in 1999 in celebration of the 50th anniversary of Lamont-Doherty. Each spring since then, four or five different Lamont researchers have given presentations on their current research. Topics have ranged from “New York City Underwater? Storm Surge Risks in the Face of Rising Sea Levels” to "How Old is the Earth and How Do We Know?” to “Plumbing the Depths: Volcanoes as Windows into the Deep Earth."

After the lectures and question and answer periods, receptions are held so that attendees can discuss the topics at greater length. Find out about this year's events.
