Figure 2. Day plots of hysteresis parameters of samples from Site 995. A. Samples from set A995, stored in anoxic conditions to prevent oxidation. Depths in meters below seafloor for each sample are indicated; arrows indicate the sequence with increasing sub-bottom depth. B. Samples from both sets A995 (solid symbols) and B995 (open symbols); B995 samples were not protected from oxidation. Note the change in both vertical and horizontal scales from Part A. Domain state fields are indicated on the plot: SD = single domain, PSD = pseudosingle domain, MD or SPM = common field for multidomain and superparamagnetic assemblages, +SPM = field representing addition of large proportions of SPM grains to an otherwise PSD or SD assemblage. Dashed lines join equal values of D_JH, indicated in italics.
