20. Abstract. -Continued 



Several significant coastal features are visible in the ERTS-1 imagery. 

 Among those are plumes of suspended sediment emerging from inlets, changes in 

 water coloration possibly due to effects of temperature change, inlet bars, 

 and cape bars. In addition, morphological changes in selected coastal land 

 features were determined by comparing ERTS-1 films obtained about 1 year apart. 



Limited water depth penetration is afforded by examining the lower MSS 

 spectral bands. Maximum penetration can be expected to measure in tens of 

 feet, depending on the phy-sical characteristics of ocean water. Although 

 inadequate for deeper penetration, this capability is adequate for exposure 

 of backshore and nearshore underwater features. 



Image resolution capability is sufficient for observation of gross coastal 

 features and processes but may not be adequate for viewing smaller features 

 such as wave patterns, morphological features on beaches, and many engineering 

 structures.
