Time-lapse imaging of ice (as well as surface isotherms) can detect motions and trajectories 

 valuable for safe ship navigation and measurements of oceanic circulation. 



In summary, although designed for meteorological applications, the DAPP system has 

 inherent oceanographic capabilities, which will provide an important foundation of 

 information for development of a practical oceanographic satellite, and baseline synoptic 

 data on waters of the globe. This effort was designed to test the value to coastal oceano- 

 graphy of both the DAPP system and this entire approach. In the end the DAPP system was 

 actually used to steer an entire surface-truth operation. It gave a quick synoptic over- 

 view, the perfect perspective for operational decision making. This is a most useful 

 development in view of today's funding situation, where research vessels are being with- 

 drawn from service. It also coincides with a time when the coastal oceanographic com- 

 munity is concentrating on multiship synoptic studies and beginning to fully appreciate 

 the mesoscaie turbulent structure of coastal regions as well as the open ocean. The 

 satellite remote sensing approach is the means to make optimum use of limited ship time, 

 to conduct "smart ship" operations in the sense that the investigator has time-lapse near 

 real-time synoptic data to direct bis sampling program. This, perhaps will be one of the 

 most far reaching concepts derived from the work. 



IV. ACKNOWLEDGEMENTS 



This study was funded by the Office of Naval Research, Geography Programs (Remote 

 Sensing) Code 414, under contract NR 387-062, as part of the Coastal Advection Research 

 Project at the Naval Oceanographic Office. Special appreciation is extended to Dr. 

 James S. Bailey of ONR, for initial access to the system and helpful constructive criticisms 

 during the progress of the study. Appreciation is extended to CDRK. Ruggles and LCDR 

 W. Mitchell of Detachment FAMOS, Naval Weapons Engineering Support Activity (1971- 

 72) NAVAIR Systems Command for introduction and initial guidance on the DAPP. The 

 author gratefully acknowledges the help and support of Naval Space Systems Activity, 

 located at Space and Missile Systems Organization, Los Angeles, for guidance, special 

 clearances, and essential procurements of system related materials. Critical to the success 

 of this project has been the outstanding cooperation and highest standards of professionalism 

 displayed throughout this effort by U.S. Air Force Personnel of the 20th Weather Squadron, 

 SAMSO, and the Air Force Global Weather Central, Offutt, Nebraska.
