Robert Newton

Robert (Bob) Newton is an oceanographer specializing in atmosphere/ice/ocean interactions in the Arctic and its peripheral seas. He also works with noble gases, stable isotopes, nutrients and other ‘tracer’ signals to derive provenance and pathways of water masses in ocean. Bob founded and directs the Secondary School Field Research Program (SSFRP), Lamont-Doherty’s internship program for pre-University students. The SSFRP recruits mainly from communities underrepresented/underserved in earth and environmental science; it is the most diverse of Lamont-Doherty’s educational programs. The program centers field- and lab-based research related to the Hudson estuary, New York Harbor, and green spaces in the NYC metropolitan area.

Fields of Interest

Physical and chemical oceanography, Arctic climate change, large-scale isotope tracer distributions in the ocean, nutrient cycling in the Arctic Ocean and the Hudson Valley, engaging teens in scientific research
