Figure 7-4

Dust in the GISP2 ice core for the period 14,000 to 10,500 years ago. (A): Number of microparticles per milliliter of meltwater; (B): Mass concentration of dust in parts per billion; (C):Mean particle size, calculated based on the number of particles; (D):Mean particle size, based on particle mass. (Compare the general shape of curves (A) and (B) with Figs. 6-12, 6-16(b), and 6-17.)
