fish catch require synoptic environmental data and 
predictions. Knowledge of regional and local 
bathymetry, circulation, and other environmental 
factors is needed to design outfalls for desalting 
and waste disposal operations. 
General mapping functions should include 
measuring and plotting magnetic and gravitational 
fields. Like sub-bottom profiling, the general 
resource development interest is in regional fea- 
tures and navigational aids with initial emphasis on 
continental shelf surveys rather than localized 
anomalies for substructure analysis. Continuous 
gravimetric surveys are limited in effectiveness by 
VI-30 
their slow speed, necessitating improved instru- 
mentation and procedures. 
Bathymetric survey methods involving multi- 
ship operations with centralized data reduction 
and mapping functions are under evaluation. Com- 
ponent deficiencies and lack of priorities have 
deterred implementation. The potentials of aerial 
and satellite color photography and of infrared 
sensing for subsurface mapping functions should 
be determined and exploited, especially in shallow 
waters and coastal areas. The potential of submers- 
ibles in such operations should receive more 
attention.
