There are 19 sitesin the LTER Network representing over 600 LTER scientists andstudents. LTER sites share a common commitment to long-term researchon the following core research topics:o Pattern and control of primary productiono Spatial and temporal distribution of populations selected torepresent trophic structure.o Pattern and control of organic matter accumulation in surface layersand sediments.o Patterns of inorganic inputs and movements of nutrients throughsoils, groundwater and surface waters.o Patterns and frequency of site disturbances.The LTER Network consists of the following sites:1. H. J. Andrews Experimental Forest (AND), Oregon.2. Arctic Tundra (ARC), Alaska3. Bonanza Creek Experimental Forest (BNZ), Alaska.4. Cedar Creek Natural History Area (CDR), Minnesota.5. Central Plains Experimental Range (CPR), Colorado.6. Coweeta Hydrologic Laboratory (CWT), North Carolina.7. Harvard Forest (HFR), Massachusetts.8. Hubbard Brook Experimental Forest (HBR), New Hampshire.9. Jornada Experimental Range (JRN), New Mexico.10. Kellogg Biological Station (KBS), Michigan.11. Konza Prarie Research Natural Area (KNZ), Kansas.12. Luquillo Experimental Forest (LUQ), Puerto Rico.13. MacMurdo Dry Valleys (MAC), Antarctica.14. North Inlet Marsh (NIN), South Carolina.15. Niwot Ridge-Green Lakes Valley (NWT), Colorado.15. North Temperate Lakes (NTL), Wisconsin.16. Palmer Station (PAL), Antarctica.17. Sevilleta National Wildlife Refuge (SEV), New Mexico.18. Virginia Coast Reserve (VCR), Virginia.The LTER Network Office is located at the University of Washington inSeattle. The Office provides leadership and coordination among LTERsites and the scientific community, provides electronic networking anddata management, and publications.The LTER Network Office has also established the LTER Remote Sensingand GIS Laboratory to syhthesize large-scale spatial analysis, usingsatellite data and Geographic Information Systems (GIS).Reference:Contacts:Rudolf NottrottLTER Network OfficeUniversity of WashingtonCollege of Forest Resources AR-10Seattle, Washington 98195Phone: 206-543-8492FAX: 206-685-0790Email: Internet > RNott@LTERnet.eduNSF, Division of Environmental BiologyLong-Term Projects in Environmental BiologyPhone: 202-357-9596Email: Internet > jCallaha@nsf.govData Availability:Availability of LTER data can be determined through the LTER NetworkOffice. The LTER Network Office maintains an Internet gopher serveravailable though most Internet gopher clients and a Home Page on theWorld Wide Web (WWW). A searchable on-line core dataset informationcatalog, FTP directories, LTER personnel, and bibliography isavailable as well as other LTER services. The dataset catalog,bibliography and personnel directory databases are WAIS-indexed toallow searches on text strings. If you have a gopher client on yourhost system, enter 'gopher LTERnet.edu' or access the LTER Home Pageon WWW.The LTERnet also has a directory of Landsat images for several sitesavailable on the Gopher. Also, Gopher servers from some of the LTERsites are presently linked into LTERnet, providing informationspecific to those sites. These can also be accessed through WWW.All of the LTER information on Gopher and FTP is accessible throughthe LTER Home Page on the World Wide Web (WWW) which can be browsedusing publically available software like MOSAIC. The address for theLTER Home Page is:'http://lternet.edu/'Instructions on how to query the Core Dataset Catalog by e-mail ratherthan through Gopher, send any message to Catalog@LTERnet.edu.
