Benjamin Holt

Education
  • B.A., Human Biology and Anthropology, Stanford University (1972)
  • M.S., Physical Oceanography, Dept. of Geology, University of Southern California (1988)
Research Interests
  • Investigations into the state of polar sea ice to identify possible changes due to climate change, through derivation of geophysical measurements using microwave remote sensing.
  • Coastal oceanography circulation and its effects on biological productivity and pollutants using multi-sensor remote sensing.
  • Development of radar instrumentation to measure sea ice thickness and ocean surface currents from airborne and space borne platforms.
Professional Experience
  • Jet Propulsion Laboratory (1978-Present)
    • Oceanography Element (1982-Present)
    • Member Technical Staff (1978-Present)
