Curriculum Vitae:

Ichiro Fukumori

  • B.S., Geophysics, University of Tokyo, Japan (1983)
  • Ph.D., Physical Oceanography, Joint Program in Oceanography, Massachusetts Institute of Technology and Woods Hole Oceanographic Institution (1989)

Research Interests
  • Analysis of ocean circulation using observations and models
  • Sea level change and ocean climate variability
  • Ocean state estimation and data assimilation
  • Numerical modeling of the ocean 


The "Estimating the Circulation and Climate of the Ocean" (ECCO) produces descriptions of the complete time-evolving state of the ocean by synthesizing nearly all extant observations with state-of-the-art models.

OMG (Oceans Melting Greenland) Icon OMG (Oceans Melting Greenland)
OMG uses the GLISTIN-A radar to measure Greenland's receding glaciers, air-dropped ocean sensors to measure the nearby oceans, as well as ship-based sonar and airborne gravity to map the depth and shape of the sea floor around the glaciers.

Selected Awards
  • NASA Exceptional Public Achievement Medal (2017)
  • NASA Group Achievement Award, Oceans Melting Greenland Team (2017)
  • NASA Exceptional Scientific Achievement Medal (2005)
