Briefing to Provide Check-Up on Arctic Sea Ice Conditions

NASA and NSIDC will hold a media teleconference on Monday, April 6, at 9:00 a.m. Mountain Daylight Time (MDT), to present the latest observations of sea ice conditions in the Arctic.

Sea ice cover over the Arctic Ocean typically reaches its maximum geographic extent and thickness just as spring begins in the Northern Hemisphere. However, the winter maximum extent has been lower during the last six winters than at any other time during thirty years of satellite records. Scientists have also observed that ice thickness and age are changing. They will present their analyses of Arctic ice cover for the 2008 to 2009 winter season at the briefing.

The teleconference participants are:

  • Ronald Kwok, NASA Jet Propulsion Laboratory, California Institute of Technology Pasadena, California
  • Walter Meier, National Snow and Ice Data Center, University of Colorado, Boulder, Colorado
  • Thomas Wagner, Cryospheric Sciences Program, NASA Headquarters, Washington D.C.

To participate in the teleconference, reporters must contact Steve Cole at +1 202.358.0918 or for dial-in instructions by 3:00 p.m. MDT on Friday, April 3. On April 6, supporting information for the briefing will be available at 9:00 a.m. MDT on the NASA Web site at: Audio of the teleconference will be streamed live on the NASA Web site at
