(Table 1) Summary of one-dimensional consolidation test results for ODP Leg 133 holes

Most of the sediments at Sites 819 through 821 are underconsolidated, likely the result of high sedimentation rates. Normally consolidated sediments appear at intervals of low sedimentation rate at Site 820. Overconsolidation occurs in the shallowest unit of Site 820, suggesting recent mass wasting, and at the deepest interval, which may define an older erosional surface.
At Site 819 for the depth range of 0 to 400 m, porosity is correlated with percentage of mud and is inversely proportional to carbonate content.
Mass accumulation rates in the upper 30 m above a major hiatus at Site 819 are fairly constant from 240 to 100 k.y., following a 50-k.y. period of slightly higher accumulation rates. The mass accumulation rate increases steadily from 100 k.y. to the present.

819至821站位的绝大多数沉积物均处于欠固结状态，其成因大概率为较高的沉积速率。820站位则在低沉积速率段出现正常固结沉积物。超固结现象分别出现在820站位的最浅地层单元（指示近期发生过块体搬运作用）以及最深层段，后者或代表一处古老的侵蚀面。
在819站位0至400米的深度区间内，沉积物孔隙度与泥质含量呈正相关，与碳酸盐含量呈负相关。
819站位某重大沉积间断上方30米的上部地层中，其质量堆积速率在240千年至100千年期间基本保持稳定，此前的50千年时段堆积速率略高。自100千年至今，质量堆积速率持续稳步提升。
