Figure AF2. Dried sediments from Sample 207-1259C-11R-4, 130–150 cm, remaining after soaking in Calgon-peroxide solution (left sieve, 2.3 g sediment) and 100% Clorox bleach (right sieve, 0.3 g sediment). The white grains in the bleach sample are predominantly loose foraminifers. Photograph was taken before the Calgon-peroxide sample was sonicated and then soaked overnight.
