Moisture and density measurements were made during Leg 177 on selected samples at a rate of about one per core section following the procedures outlined in ODP Technical Note 26 (Blum, 1997). Samples were dried for 24 hr either in an oven at temperatures of 105°C or in a freeze-dryer.
Dry density and water content data are given in Table T3 and plotted vs. depth in Figure F5A (0-250 mcd). These two parameters are inversely related, which is expected because they are both directly related to the dry mass of the solids (Blum, 1997). Plotting dry density and weight percent CaCO3 vs. depth, shows no relationship between the two measurements (Fig. F5B, F5C).
