Geological Survey FI-62 $106,000 



FY-63 $123,000 

 Current and proposed studies of the Geological Survey are concerned with 

 the hydrologic cycle through the marine and near -shore environments. 

 The principal effort is in shallow ocean areas where the sea is in direct 

 or indirect communication with fresh surface water and ground water. 

 Included in the studies that will be pursued in FY-63 are: geological 

 history of river estuaries and lagoon areas; movement of ground and 

 surface water to the ocean; salt water incursion into fresh water 

 supplies; occurrence and origin of fresh and salt water bodies in 

 coastal areas; circulation and dispersion of dissolved and suspended 

 solids in coastal areas; dynamics of tidal and contiguous ground waters; 

 and the development of techniques and methods for measuring processes 

 and obtaining data. Among other things, these studies will provide 

 knowledge about the sources, the circulation, and the fate of radio- 

 active, organic, and industrial waste pollutants; as well as the products 

 of natural weathering and erosion in ground water and rivers that drain 

 into the sea. 



Determination of significant physical and chemical properties and patterns 

 will of necessity be undertaken in connection with local and regional 

 studies of general environments of sedimentary systems.

Coast Guard FY-62 $ 



FY-63 $ 

 Within the Coast Guard, the principal field of research into physical 

 and chemical properties and the interrelated dynamic processes lies 

 in the International Ice Patrol. The principal area of interest is 

 the Northwest Atlantic Ocean, chiefly the Grand Banks and the Labrador 

 Sea, These waters have been under continuing study since 191ii for the 

 •purpose of better understanding the factors which affect the origin, 

 drift, transport and deterioration of icebergs. Toward this end, 

 Ice Patrol research includes water mass analysis, surface and sub- 

 surface currents, volumetric transport and heat budget studies of 

 the area. 



In FY-63, the Ice Patrol oceanographic vessel CGC EVERGREEN will occupy 

 approximately I4.OO oceanographic stations during the period March-August. 

 In addition, a network of buoys will be established across the Labrador 

 Current to study short term" fluctuations in that flow. Results of the 

 surveys will be analyzed at the Ice Patrol Oceanographic Unit Offices 

 located at the Woods Hole Oceanographic Institution. 



In other fields of oceanographic research. Coast Guard activities are 

 principally those of data collection in cooperation with other agencies. 

 These include operations of ocean stations, Bering Sea Patrol, polar 

 operations, lightships, and offshore light towers.
