  1. McMurdo Dry Valleys Long Term Ecological Research Program Coordination • People • Data contributions • Directions

  2. Interested people in the MCM-LTER Geochemistry • Berry Lyons, Byrd Polar Research Center, Ohio State Soil ecology and biogeochemistry • Ross Virginia and Jeb Barrett, Dartmouth College • Diana Wall, Colorado State University Contemporary and paleo-climate, met- station network • Andrew Fountain, Portland State University • Peter Doran, University of Illinois Chicago

  3. Potential Data Contributions From MCM-LTER Information on soils, soil biology and biogeochemistry • Online spatially explicit soils database • Spatial scaling and patterning of soil biology and biogeochemistry Meteorological Station Network • LAWN network • Soil microclimate network

  4. The LTER Automatic Weather Network (LAWN) 13 stations (see map) Stations routinely sample sensors every 30 sec. Summary statistics are logged (avg, min, max, ect) every 15 min. to solid state storage modules.

  5. Not shown: Beacon Valley Met Station Cape Hallett Met Station The Met Station Network

  6. The LTER Automatic Weather Network (LAWN) Data Collected Air temperature @ 3 m Relative humidity @ 3 m Soil temperature @ 0, 5 and 10 cm Wind speed and direction Solar flux in/out PAR Barometric Pressure* Precipitation* * Not universally deployed

  7. Examples of long term climate data sets. Doran et al. 2002. Nature

  8. Soil thermo-couple and reflectometer data

  9. Online public access met data • Relational database • Search queries for specific times and locations • Full meta-data for all observations http://huey.colorado.edu/LTER/meteordata.html John.E.Barrett@Dartmouth.edu

  10. What are the data collection priorities of the Antarctic permafrost community? How can LTER contribute to Antarctic permafrost community? • What are the opportunities through existing data • and ongoing routine data collection? • What are the opportunities for new initiatives and collaboration?
