Crete Ice Core Data Readme

Prepared by Dave Fisher, Nov. 30, 1994

These file names give the site name at Crete (ct), the year the core was drilled, the specific core (a-h) or pit, and the descriptions give the type of data, the sample interval, the accumulation rate (lambda), and a short code for easy identification (in parethesis).
