Although we have good data on the soluble portions of copper and lead only, there is no evidence of any anomalous regional trends, and it is expected that the concentrations of other trace metals in solution will show the same low ranges given in earlier publications for the Gulf of Alaska (, Burrell 1978).

The geochemistry of the surface sediments is discussed in Chapter 19 and need not be considered further here. HEAVY METAL CONTENTS OF MARINE MAMMALS Fig. 21-3 shows the localities of sacrificed seal samples collected on two separate cruises in March- April and May-June of 1977. The original objective of this project was to look for statistical differences between the heavy metal contents of four species of seal which were thought to have distinctive feeding habits. Our data are o cc
