areas. The image slicing technique in which photo density levels are isolated from the 

 composite photo was used for image enhancement. Depth contours were compared with 

 photo density levels. Good correlation of image density levels and charted depth contours to 

 a depth of 20 fathoms was found in on photo; none was optimum for water penetration. 

 Image enhancement is also useful in identifying suspended sediment patterns. Several 

 enhanced photos cover coastal areas of North Carohna, South CaroUna, and Georgia. Major 

 features on the enhanced images are described. Image enhancement of satellite photos is 

 concluded to be useful for determining water depths and other coastal applications.

Article describes an airborne infrared scanner with oscilloscope and camera recording to 

 examine thermal anomalies along the coast of Hawaii. The study \^^s to detect areas where 

 cool ground water was being discharged by springs into the warmer ocean water. Thermal 

 anomalies were best detected on imagery obtained in the early morning. The scanner was 

 concluded to be useful for coastal reconnaissance of thermal anomalies. Monitoring 

 dispersion patterns of cool water discharges may have application in the qualitative 

 evaluation of coastal currents.

Article discusses approaches to increase the water penetration of color films. A method of 

 simulating selected combinations of film emulsion layers by printing multispectral images is 

 presented. The simulated photos show that eUminating the blue-sensitive or yellow 

 dye-forming emulsion layer is not the best approach to increasing depth penetration. A 

 more effective method is the use of emulsion layers sensitive to the proper region of the 

 spectrum as determined by the transmission characteristics of the water. Multispectral 

 sensing is useful for research and selection of film emulsion layers, but is not feasible when 

 many photos are required because of the labor necessary for data presentation. The 

 development of color films with the best combination of emulsion layers for water 

 penetration is recommended.

Article discusses formation of tidal inlets and washover fans along barrier beaches. It 

 concludes that tidal inlets are opened by wave attack from the lagoon side of the barrier at 

 tidal creeks or channels in the marsh and washover fans are formed by attack from the
