   Description: 
      Abstract:
         The International Polar Year Historical Data and Literature collection 
         (formerly known as the Discovery and Access of Historic Literature from the 
         IPYs (DAHLI) project) is an online data collection consisting primarily of 
         photographs, publications, and observational data records from, and relating 
         to, the first two International Polar Years (IPY) 1882-83 and 1932-33 and the 
         International Geophysical Year (IGY)1957-58. Examples of data contained in 
         observational records include, but are not limited to: air  magnetic vertical 
         intensity, air conductivity, atmospheric-electric observations, auroral log 
         data,  potential-gradient electrographic data, dust counts, and meteorological 
         observations.  Photographs  within the collection include those from the 
         Wilkes Station in Antarctica, the USGS survey of FletcherÂ’s  Ice Island, and 
         the DTM Geophysical Laboratory Library.  Publications within this collection 
         primarily  consist of government (national and international) bulletins and 
         reports on activities during the  International Polar and International 
         Geophysical years.  Other data include audio files of interviews  recorded 
         during NCARÂ’s Oral Histories Project, and a video on Drifting Station Alpha 
         during the IGY,  published by NSIDC.

         Data were contributed by several institutions:  the University of Colorado 
         Libraries, the Carnegie  Institution of Washington, National Snow and Ice Data 
         Center (NSIDC), and The National Center for  Atmospheric Research (NCAR). 

         The data collection contains approximately 800 digital objects, formats of 
         these objects include:  PDF,  TIFF, JPEG, MP3, and MPEG.  Most objects are 
         freely accessible and downloadable, except where prohibited by  copyright.  

         Temporal coverage of this data collection is between the years 1882 and 1958.  
         Geographical coverage  is global, with data originating from Europe, Asia, 
         North America, and South America and relating  primarily to specific glaciers 
         and other locations in North America (Alaska and Canada) and Antarctica.

         All materials without use constraints are accessible by the public through the 
         ROCS Archives Catalog.   Reference images and PDFs of publications and data 
         are available for immediate viewing and download.  Please request high 
         resolution TIFF image files through the Archives catalog.
