Scientists at NSIDC

Scientists from around the world use data housed at NSIDC to support their research. Some of these scientists work here at NSIDC (see list below), providing both context and input concerning our data management activities. NSIDC also works with a network of affiliated scientists. Through their research, our scientists help further understanding of the many changes that our planet is undergoing.

NSIDC scientists are widely published in such journals as Geophysical Research Letters; Journal of Geophysical Research; Journal of Climate; Arctic, Antarctic, and Alpine Research; EOS, Transactions American Geophysical Union ; and IEEE Transactions on Geoscience and Remote Sensing. Our scientists’ expertise has reached a wide audience through Scientific American, The New York Times, The Washington Post, CNN, and the British Broadcasting Corporation (BBC), just to name a few.

Scientists pursue their work as part of the CIRES Cryospheric and Polar Process Division, University of Colorado, Boulder. National agencies fund research through the peer review proposal process.

Florence Fetterer

Principal Investigator, NOAA @ NSIDC

Sea ice; applications-oriented remote sensing; data rescue; data set development

  • Project manager, Contribution to High Asia Runoff from Ice and Snow (CHARIS): CHARIS is USAID-supported project that promotes scientific collaboration and data sharing while conducting research on science questions that have broad economic and political impact.
  • PI, Ice Concentration and Ice Age Products for ArcticCAP: This work has two overarching deliverables: an improved daily ice concentration product and a proxy ice thickness product, both for use in sea ice modeling at the Navel Research Laboratory.
  • PI, Managing the SCICEX Data Collection: The SCience ICe EXcercise (SCICEX) program is a collaboration between the U.S. Navy and the marine research community to utilize data acquired by nuclear-powered submarines for the study of the Arctic Ocean. Unlike surface ships, submarines are able to acquire scientifically valuable data regardless of sea ice cover, weather conditions, and time of year.
  • PI, Sea Ice Concentration Climate Data Record Sustainment, Enhancement, and Production of Value-Added Products through the Sea Ice Index (NOAA)
