Note:

The cores were sampled at distinct lithologic layers rather than a regular interval.

Table 2 shows the sediment distribution characteristics sampled.

The layer represented by each sample is shown by depth below grade in feet of the Layer Start and Layer End columns, For example, Core VC98 38, Layer 2 is 5 feet thick, and represents the sediment starting 5 feet below the surface and ending at 10 feet below the surface.
