Table 19-3 demonstrates the close correlation of extractable contents of heavy metals from the sediment with the weight fraction of fine- grained sedimentâ, with available solid-phase surface area. ACKNOWLEDGMENTS This work, Institute of Marine Science Contribu- tion No. 405, was supported largely by the Bureau of Land Management through interagency agreement with the National Oceanic and Atmospheric Adminis- tration, under which a multiyear program responding to the needs of petroleum development of the Alas- kan Continental Shelf is managed by the Outer Continental Shelf Environmental Assessment Program Office, and by the State of Alaska. Sediment samples for clay minerals studies were kindly supplied by Drs. J. S. Creager and C. H. Nelson. We are grateful for permission to include unpublished data by Dr. D. Robertson.
