Group: Summary

   This data set includes microparticle concentration, electrical conductivity, 
   and density measurements from the West Antarctic Ice Sheet (WAIS) Divide deep 
   ice core, WDC06A. Microparticle concentration data are reported as total 
   particles per ml of meltwater. Concentration was measured using a laser 
   detector and the University of Maine WAIS Melt Monitor system. Conductivity is 
   measured in micro-Siemens per cm (uS/cm). Density data were collected on 3 by 
   3 by 100 cm sticks from the WDC06A core, using the Maine Automated Density 
   Gauge Experiment (MADGE). Density data span 0 to 160 m in depth, while the 
   particle and conductivity measurements span the upper 577 m of the core. 

   Data are available via FTP in ASCII text format (.txt).
