of the sediment. and organic carbon analyses were displayed as histograms (Fig.13, 1 - 7). The first column on the left hand side marked C. is the organic carbon content of the mud measured by the Walkley and I Black technique. The other seven columns represent the percentages of each grade of material measured in phi unitSliJ The degree of sorting may be estimated by examining the columns and relating the percentage of the tallest to the average of the rest. This may be illustrated by consulting the histogram for site i22, (Fig 13.'6), where the sediment is almost all about phi 4. Directly below this is the histogram for site i19, about 900 metres away where there is a wide range of grades making it very difficult to classify.
