ABSTRACTS

This CD-ROM contains the field data from SHEBA snow and ice studies. This web site is intended to provide 1) background on SHEBA, 2) an overview of our observations, 3) metadata for our results, and 4) a sense of what it was like to spend a year at Ice Station SHEBA. In addition to the web page our data are archived in ASCII format in a main directory DATA. There are sub-directories for different components of the work. See the Data summary page for a quick look at the data and metadata..
