Figure 27 shows one fonr of data output obtained from CEAS, 

 an identification of various anomalies in the seafloor in the 

 Persian Gulf. 



The availability of these data in ARC fNFO format makes them 

 attractive to civilian users because they can be easily added to 

 existing databases. Much of the data available from CEAS is 

 already available in terms of general type and regional coverage. 

 However, the value of this system lies in the high quality of 

 the data (resolution and multiple measurements over a lengthy 

 time) and the data now available from previously denied 

 regions. 



The CEAS database has an effect on a number of marine 

 engineering issues: 



cable, and pipeline routing; 



• Environmental baseUne studies, pollution control; 



• Hazards to navigation — detection of shoals, coral reefs, 

 shipwrecks, and abandoned strucwres; and 



• Contribution to global change and soUd earth geophysics 

 studies. 



CEAS would be particularly useful m developing and applying 

 interpretation methods to remote sensing data from many parts 

 of the worid's oceans (e.g. Space Radar Laboratory SAR 

 imagery). CEAS would help provide the "surface truth" to 

 enable interpretation to be done in a cost effective manner. 

 Surface information not only aids in confirming correct 

 interpretations, but allows false interpretations to be dis- 

 covered and discarded.

To convey some sense of how CEAS might appear to a user. 

 Figure 28 shows several database access options for the western 

 Atlantic. Depicted are sediment type data, ocean temperature 

 at a specified depth from MOODS, sea surface temperature 

 from satellite data, and acoustic ocean noise.
