Most of the data used in the preparation of' this atlas were obtained under Project NR 083 012 within the Oflice of Naval Research Contracts Ngonr-520tlll, Nonr-477 1!, Nonr-477 0!, and Nonr-477 3!. The intensive study oF Carr inlet was made in 1954 and 1955 for the U,S, Bureau of Ships Con- tract No. 25 ls-626IA, Negotiation 417/54!. Support for the preparationof the many drawingsand for publication was under contractsfrom the State of Washington, Department oF Ecolo D, and through grants NG-1-72 and 04-3-158-42 from the National Oceanic and Atmospheric Administration to the Washington SeaGrant Program.
