LTER
The National Science Foundation (NSF) established the U.S. Long-Term Ecological Reseach (LTER) Program in 1980 to conduct research on long-term eclogical phenomena in the United States. There are 19 sites in the LTER Network representing over 600 LTER scientists and students. LTER sites share a common commitment to long-term research on the following core research topics: o Pattern and control of primary production o Spatial and temporal distribution of populations selected to represent trophic structure. o Pattern and control of organic matter accumulation in surface layers and sediments. o Patterns of inorganic inputs and movements of nutrients through soils, 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), Alaska 3. 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 in Seattle. The Office provides leadership and coordination among LTER sites and the scientific community, provides electronic networking and data management, and publications. The LTER Network Office has also established the LTER Remote Sensing and GIS Laboratory to syhthesize large-scale spatial analysis, using satellite data and Geographic Information Systems (GIS).

The LTER Network Office maintains an Internet gopher server available though most Internet gopher clients and a Home Page on the World Wide Web (WWW). A searchable on-line core dataset information catalog, FTP directories, LTER personnel, and bibliography is available as well as other LTER services. The dataset catalog, bibliography and personnel directory databases are WAIS-indexed to allow searches on text strings. If you have a gopher client on your host system, enter 'gopher LTERnet.edu' or access the LTER Home Page on WWW. The LTERnet also has a directory of Landsat images for several sites available on the Gopher. Also, Gopher servers from some of the LTER sites are presently linked into LTERnet, providing information specific to those sites. These can also be accessed through WWW. All of the LTER information on Gopher and FTP is accessible through the LTER Home Page on the World Wide Web (WWW) which can be browsed using publically available software like MOSAIC. The address for the LTER Home Page is: 'http://lternet.edu/' Instructions on how to query the Core Dataset Catalog by e-mail rather than through Gopher, send any message to Catalog@LTERnet.edu.
