DATA DESCRIPTION: 

A continuous melting technique, combined with continuous flow analysis,
has been developed for measurements of chemical trace species in ice cores
directly in the field (Sigg et al., 1994). A subcore with a cross section
area of 18x18mm2 cut from the main core is used for the simultaneous
analysis of the four components. The subcore is melted continuously from
one side at a constant rate. The main advantage of this method compared to
conventional sampling and analytical procedures of discrete samples are
given by the high spatial resolution (ca. 1cm for Hydrogen peroxide,
Ammonium and Formaldehyde; 3cm for Calcium) combined with a significant
reduction in sample handling. The spatial resolution is only limited by
the sample dispersion in the melting system and the analyser. The
detection limit for hydrogen peroxide is 1.7 ppb.  Ages are years before
1950.00, as calculated from the glaciological timescale (file
gripage.dat).
