Group: Summary

   The Global Lake and River Ice Phenology Database contains freeze and 
   thaw/breakup dates as well as other descriptive ice cover data for 865 lakes 
   and rivers in the Northern Hemisphere. Of the 542 water bodies that have 
   records longer than 19 years, 370 of them are in North America and 172 are in 
   Eurasia. 249 lakes and rivers have records longer than 50 years, and 66 have 
   records longer than 100 years. A few water bodies have data available prior to 
   1845. This database, with water bodies distributed around the Northern 
   Hemisphere, allows for the analysis of broad spatial patterns as well as 
   long-term temporal patterns.

   This data set was prepared by the North Temperate Lakes Long-Term Ecological 
   Research (NTL-LTER) program at the Center for Limnology (CFL) at the 
   University of Wisconsin-Madison (UW) from data submitted by participants in 
   the Lake Ice Analysis Group (LIAG). LIAG is an international ad hoc group of 
   scientists who participated in a 1996 workshop sponsored by CFL and the 
   National Science Foundation (NSF) Division of Environmental Biology (DEB) 
   Long-Term Ecological Research (LTER) program as well as other data 
   contributors. The group is especially interested in continuous data extending 
   for 30 years or more. If you wish to contribute data for inclusion in the 
   database, please contact Corinna Gries (cgries@wisc.edu) at CFL.

   The data are stored in a standard format in a database. NSIDC has developed a 
   Web-based user interface to the database that allows users to search the 
   database and retrieve data by the available parameters. The interface also 
   includes a link to more general information about the lakes and rivers in the 
   database, including, for example, latitude and longitude. The output can be 
   directed to a Web browser, a gzipped file, or a tab-separated ASCII text file.

   Note: The term phenology in the data set title refers to the 
   seasonal phenomenon of the freezing and thawing of lake and river ice.

   Access to the Global Lake and River Ice Phenology Database data set is 
   unrestricted, but users are encouraged to register for the data. Registered 
   users will automatically receive e-mail notification about any product changes.
