This CD contains two directories ICEWEB and ICEDATA:

ICEWEB contains a browser based description of our data replete with words, pictures and graphs.
To access this information
     1. Start your browser
     2. address is    x:\iceweb\index.htm
          where x is the drive letter of your CD drive


ICEDATA contains snow and ice datafiles. 
This main directory has five primary subdirectories where data and metadata 
are stored. The directories, along with a thumbnail description of their 
contents are listed below.

* AERIAL - data relating to helicopter survey and photography flights
       * Heloalb - helicopter based albedo measurements
       * KT19 - helicopter based surface temperature measurements
* MASS - data relating to mass balance studies
       * EM -  electromagnetic induction surveys of ice thickness
       * Gauge - year-long data from 135 thickness gauge/ablation stake combinations
       * Pond - observations of melt pond areal extent, depth, temperature, and salinity
       * Temper - time series of ice temperature from thermistor strings at 8 sites
       * Waterlev - results from waterlevel recorders at Quebec and the Doghouse
* OPTICS - optical measurements of albedo and transmittance 
       * In_ice - in ice profiles of upwelling and downwelling spectral irradiance at selected sites
       * Specalb - spatial and temporal variability of spectral albedo from 300 nm to 2000 nm 
       * Totalb -  spatial and temporal variability of wavelength-integrated albedo
       * Trans -  transmitted spectral irradiance at selected sites
* SNOW - snow observations 
       * Snowsurv - surveys of snow depth conducted along four lines during the SHEBA year
       * SnowIOP - observations made during a snow Intensive Observation Period in Spring 1998
* ANCILL - ancillary snow and ice measurements made during SHEBA
       * Icecores - ice physical properties measured for selected cores
       * Perm - ice permeability observations for selected sites
       * Sal - ice salinity and O18 observations
       * Soot - observations of soot levels at SHEBA
       * Stress - measurements of internal ice stress at 8 sites through the SHEBA year
       * Topo - surface topography observations made during spring and summer
