Data consists of concentration of insoluble dust in the EPICA Dome C
cores, 100-3138 m depth.
Dust concentration and size distribution were measured by a 256
channel CoulterCounter, set to register particles in the size range
from 0.7-20 B5m. In calculating mass concentrations, density was
taken as 2500 kg m-3.
