1. Highlights of GCMRC activities:

USGS participates in National Space Reference System: Grand Canyon Monitoring & Research Center (GCMRC) has finalized coordinates for 16 primary control stations for inclusion into the National Spatial Reference System (NSRS). An Internet Map Server link has been created which displays the network control stations in the Grand Canyon region: http://www.gcmrc.gov/ims/survey_nsrs The NSRS improves the availability and accuracy of positional information necessary for the development of an accurate spatial database which will be used for determining physical, cultural and biological changes to the Colorado River ecosystem (CRE). The 16 stations have been and will continue to be used as primary reference for airborne remotely sensed data and for static GPS control surveys along the CRE. The Grand Canyon geodetic control network is used for spatial referencing of terrestrial and hydrographic surveys of the Colorado River corridor, as well as QA/QC of airborne photogrammetry and LiDAR. The high accuracies of these coordinates ensure that all future data sets will be referenced to, and tested by, the most accurate geodetic control available. In addition, the network and local accuracies are certified by the National Geodetic Survey and the National Spatial Reference System. Visit sites:

USGS and Grand Canyon Youth Organization Partnership for Science (Update): The Grand Canyon Youth Organization participated in their first data collection effort, on a trip which launched June 5th for two weeks. Twenty high school youth from nearby southwestern states successfully recorded detailed site descriptions and photo-documented over 100 geo-referenced control points along the Colorado River for inclusion into a web-accessible database. The control points are used by scientists to geo-reference data collected along the Colorado River. The youth and river guides did an excellent job collecting this information. Afterwards, youth expressed positive thoughts on the trip and the importance of the science service project. Another youth volunteer trip will be launching on August 5, 2004, to complete more of this valuable project. Contact: Kristin Brown, USGS, Flagstaff, AZ, (928) 556-7084, kmbrown@usgs.gov

Chief Scientist Stint Provides Opportunity for Internal Sharing: Dr. Jeffrey Lovich, Chief of the Grand Canyon Monitoring and Research Center, (GCMRC), located in Flagstaff, AZ, recently served a detail as the Acting Chief Scientist for Biology at USGS Headquarters in Reston, Virginia, from June 2-26, 2004. The Chief Scientist works directly for the Assistant Director for Biology. While in Reston, Jeff gave a symposium to the Director and the Director's staff on the role of the GCMRC in the Glen Canyon Dam Adaptive Management Program.

2. GCMRC in the news:

SBSC Director Interviewed on Phoenix radio station: Denny Fenn, Director of the Southwest Biological Science Center which is home to the Grand Canyon Monitoring and Research Center, was interviewed live on Phoenix radio station KFNX FM 1100 news/talk radio program on Wednesday morning, June 9. The newscaster was interested in what is happening in Grand Canyon and how the Adaptive Management Program is helping to resolve difficulties created by Glen Canyon Dam operations. The station's interest in this topic had been stirred by the AP article written by reporter Seth Hettena entitled Panel Seeks Solution to Grand Canyon's Woes that appeared earlier this week in the Phoenix paper.
