the vegetation community types. Grass samples were collected to determine productivity of 

 the different classes. Authors conclude that color infrared photos can be used successfully 

 to map the distribution of pure stands of tidal marsh but that ground checks are necessary 

 in mixed vegetation.

 LANGFELDER, L. JAY, STAFFORD, DONALD B., and AMEIN, MICHAEL, "A Recon- 

 naissance of Coastal Erosion in North Carohna," A Report Prepared for the State of 

 North Carolina, Department of Civil Engineering, North Carolina State University, 

 Raleigh, N. C, Dec. 1968. 

 Keywords: Aerial Photographs, Beach Erosion, North Carolina 



Paper presents results of a coastal erosion survey along 330 miles of coast using photo and 

 wave refraction methods. Advantages and hmitations of the techniques are discussed. The 

 photo procedure uses measurements on photos taken at different points along the dune hne 

 and high water line of the transient beach. Difference in ground distances computed by 

 multiplying tlie measurements by the photo scale represents the change in the dune Une and 

 high water line. Total erosion is converted to annual rates. Results of the photo survey are 

 presented and compared to the wave refraction method.

Coastlines on Hawaii," Technical Report No. 26, Water Resources Research Center, 



University of Hawaii, Honolulu, Hawaii, Dec. 1968. 

 Keywords: Infrared Imagery, Thermal Anomalies, Hawaii 



Report describes a program for infrared coastal imagery of the Kau and Puna Districts of 

 Hawaii. An infrared scanner with oscilloscope that monitored and recorded on film was 

 used. This system has a narrow field of view requiring a 11,000-foot altitude for an image of 

 1,000 feet on each side of the scanner. Equipment and operating procedures are described. 

 The infrared imagery survey was to detect and evaluate areas along the coast where springs 

 were discharging cool ground water into the warmer ocean water. Report notes that not all 

 thermal anomalies are spring discharges and a ground survey should be made along with the 

 infrared surveys.
