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 general circulation using observations and models to understand processes controlling the ocean's mean state and temporal variability
  • Studies of climate variability, its impact on and the role of ocean circulation
  • Data assimilation to estimate the complete time-variable, three-dimensional circulation of the ocean
  • Development and advancement of methods in ocean data assimilation and numerical ocean modeling


The Estimation of the Circulation and Climate of the Ocean (ECCO) is a consortium effort to estimate the time-varying, 3-D state of the ocean circulation by synthesizing ocean observations with state-of-the-art ocean models.

OMG (Oceans Melting Greenland) Icon OMG (Oceans Melting Greenland)
OMG will use NASA’s G-III to fly the Glacier and Ice Surface Topography Interferometer (GLISTIN) in order to generate high resolution, high precision elevation measurements of Greenland’s coastal glaciers during the spring.
