Abstract : The question pertaining to the acceptance of a standard drying temperature of about 110C 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 150C 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 150C 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. (Author)
