Representing the broad range of Earth science disciplines including life sciences, oceanography, paleoclimate, cryosphere, hydrology, human dimensions, geophysics, and atmospheric science is an active Science User Working Group. Members are chosen for their interest in NASA's directory effort, and for their understanding of the importance of high quality data management.

The composition of members for the June 2010 UWG included Chairperson, Dr. Hubert Staudigel Scripps Institution of Oceanography; Dr. Benno Blumenthal, Lamont-Doherty Earth Observatory at Columbia University; Mr. Eugene Burger, NOAA Pacific Marine Environmental Laboratory; Dr. Wyn Cudlip representing the CEOS IDN; Dr. Vicki Ferrini, Lamont-Doherty Earth Observatory; Ms. Vivian Hutchison, USGS/Biological Resources Division (BRD); and Mr. David Toll, NASA Goddard Space Flight Center.    The GCMD Science User Working Group works under the GCMD UWG Terms of Reference.

We wish to express our gratitude for those who have served on the GCMD's Science User Working Group in previous years.
