 Paper Presented at the Annual Meeting of the Geological Society of America, Atlantic 

 City, N.J., Nov. 10, 1969, 10 pp. 

 Keywords: Satellite Photographs, Coastal Processes, North Carolina 



Paper discusses patterns of turbid water plumes along coastUnes as recorded on Apollo IX 

 photos. Patterns are interpreted as suspended sediment being transported by currents. The 

 horizontal gradient of the water color or intensity of the turbid water plumes is correlated 

 with sediment concentration. Data is presented on capability of color, color infrared, and 

 black and wliite films to record turbidity patterns at different sediment concentrations. 

 Analysis of turbid plumes can be used to examine circulation patterns in coastal areas. 

 Repeat photo coverage to study dynamic coastal conditions is emphased. Slides were used 

 to show turbid plumes in different areas; most covered the North Carolina coast.

Article describes the prototype equipment and operating principles of an airborne 

 fluorometer which operates on the principle of a Fraunhofer line discriminator and can 

 detect fluorescence in rhodamine aqueous solution. Concentrations of five parts per bilHon 

 can be detected in turbid water. In controlled tests over a tank, the device detected 

 concentrations of one part per billion. Results of shipboard and airborne tests from a 

 helicopter are presented. The device is not effective on cloudy days since sunlight is required 

 to excite fluorescence. The airborne fluorometer is useful in current and dispersion studies 

 in bays and estuaries and has the potential to detect certain types of water and oil pollution.

Cliffs by Using Aerial Photographs," Coastal Engineering in Japan, Vol. 12, No. 2, Dec.

 Article describes a study in comparing the location of coastal cliffs on topographic maps to 

 determine the rate of cliff recession due to wave erosion. The maps were prepared by 

 photogrammetry from photos taken in 1960, 1965, and 1967. Study area was on the 

 east-central coast of Japan and was 9 km. long. A brief description on the use of photos was 

 presented. Article has additional data on cUff erosion.
