The Lamont-Doherty Earth Observatory (LDEO) offers two distinct summer internship opportunities designed for undergraduate students interested in Earth and ocean sciences. The Lamont Summer Intern Program is open to undergraduates from U.S. colleges and universities, providing a hands-on research experience under the guidance of a Columbia-affiliated scientist. Concurrently, the Earth Intern Program specifically caters to Columbia and Barnard undergraduates, offering a similar immersive research experience with an LDEO-affiliated scientist. Both programs feature participation in special lectures, workshops, and fieldtrips to enrich the scientific learning experience. Interns receive a ten-week stipend of $6000 and free housing in an air-conditioned Columbia University dormitory, facilitating their focus on research within a supportive academic environment.
