PLATE 6 
Fig. 6. Diagram showing the results of the analysis of the samples taken 
with the bottom-sampling apparatus. The stations are arranged at proportionate 
distances along the interrupted horizontal axis. The vertical axis represents 
depth in centimeters. The distance of the center of each circle below the 
zero-point on the seale denotes the distance of the middle of the section of 
the sample below the surface. The symbols have the same significance as in 
the preceding chart.
