DESCRIPTION: 
Copenhagen 860124
This data set contains delta o18 data versus depth for the Dye-3 core in
South Greenland. The data are arranged in 5 columns, each columnn containing
the depth of the bottom of the sample. The next number is the delta
value, calculated as the mean value of all samples between this depth, and the
previous depth (towards the surface). The delta values are not corrected for,
e.g., topographical isotope effects upstream upstream.

The data has 1677 lines, each 100 characters wide.


Note that all depths are measured along the core according to the main
core log. For conversion to vertical depths, see
