Peter F. Worcester is a research oceanographer emeritus in the Cecil H. and Ida M. Green Institute of Geophysics and Planetary Physics at Scripps Institution of Oceanography, University of California, San Diego.

Worcester’s primary research interests are in acoustical oceanography and underwater acoustics. His work has focused on the application of acoustic remote sensing techniques to the study of ocean structure and circulation. He has been engaged in the development of the technique of ocean acoustic tomography since its inception, including the development and deployment of the required instrumentation. He has participated in numerous experiments applying the technique to oceanographic and acoustic problems in the North Pacific and North Atlantic Oceans, the Greenland Sea, the Arctic Ocean, and the Strait of Gibraltar.
