including evaluation of the influence of such wastes on 

 fishery resources and relationship to the health of consuming 

 populations , 



5. Field studies to determine dispersal patterns and velocity 



of water movements in inshore waters, horizontal and vertical 

 velocities in estuarine and inshore tidal movements, and 

 sedimentation rates under various conditions of water movement 

 and marine topography. 



The Public Health Service hopes to implement its authority to establish 

 fellowships and make training grants at the graduate level, including 

 support in the oceanographic sciences . It will continue to make grants 

 for research in oceanography and oceanographic-related projects., 

 Consultative services will be provided to state agencies and other 

 federal agencies „ Comprehensive programs for water pollution control 

 for the Columbia River Basin, the Chesapeake Bay and Susquehanna River 

 Basins, the Lower Delaware River and Raritan Bay Basins, and the 

 Tri-State Metropolitan and Hudson River Basins (New Jersey, New York 

 and Connecticut) will include the necessary research and studies for 

 the estuarine and harbor areas, including the fate of radioactive 

 materials in the Columbia River estuary. 



In cooperation with other state and Federal agencies, the Public 



Health Service conducts radiological environmental surveys in estuaries. 



In some instances these surveys were originated to obtain information 

 about the background radiation levels in an estuary prior to the 

 start of nuclear operations. In other cases, surveys were initiated 

 to assure that the nuclear operations do not cause high activity in the 

 marine food supply, and in still other cases they were designed to 

 obtain basic information as to the route of radio nuclides from marine 

 disposal to the food chain. In these investigations attention is 

 focused towards finding indicator organisms and correlating the 

 concentrations of radioactive substances in these organisms to the 

 radioactive discharge from the source. 



All estuary environmental survey projects are conducted on a basis 

 that allows direct comparison of data and data examination. The 

 samples taken and the division of samples have been detailed so as 

 to be compatible with other estuarial areas and will allow for more 

 precise and detailed data reporting and comparison than previously 

 were possible. The samples are divided into significant component 

 parts and the data are reported in a form that is adaptable to computer 

 punched card manipulations. 



The purpose of all sampling is: 



1. To determine the radiation levels of seafood with due regard 

 to nuclear weapons testing fallout, nuclear operations and 

 other sources;
