Abstract
The question pertaining to the acceptance of a standard drying
temperature of 110±5°C in making water content determinations of
soils has been extended to the oven drying of marine sediments. The
implementation of a temperature within the 130 to 150°C range appears to be just as adequate as the accepted standard for the drying
of inorganic sediments and has the added advantage of shortening
the drying time. Increasing the temperature above 150°C does not
appreciably reduce the drying time and may begin to break down the
less stable clay sediments such as montmorillonite. The water content
determinations appear to fluctuate in a random manner with
increase in drying temperature suggesting that the mineralogy of
the sediments somehow controls water content. The concept of
normalized water content is introduced and appears to be an invaluable
aid in considering the relationships between water content,
sample weight and drying time.
