RESEARCH AND DEVELOPMENT, 1974 



During the spring of 1974, responsibility for In- 

 ternational Ice Patrol research and development 

 was transferred from the Coast Guard Oceano- 

 graphic Unit, Washington, D.C. to the Coast 

 Guard Research and Development Center, Gro- 

 ton, Connecticut. These tasks include iceberg 

 detection and tracking, drift and prediction, de- 

 terioration, destruction, and production. 



During the Ice Patrol cruises of USCGC 

 EVERGREEN, an "Iceberg Tagging and 

 Tracking Project" was conducted. The interim 

 report by R. W. Scobie and R. M. Hayes of the 

 Coast Guard Oceanographic Unit and R. Q. Robe 

 of the Coast Guard Research and Development 

 Center is included as Appendix A to this Bul- 

 letin. 



Later during the summer, USCGC EDISTO 

 conducted a "Labrador Coast Oceanographic 

 Survey". A summary is included in this Bulletin 

 as Appendix B. EDISTO also conducted iceberg 

 studies in July and August 1974 in the Labrador 

 Sea and Baffin Bay under the direction of R, Q. 

 Robe of the Coast Guard Research and Develop- 

 ment Center. These projects investigated the 

 relationship of iceberg heights to drafts and total 

 mass determinations relative to above surface 

 dimensions. They will be reported in subsequent 

 Ice Patrol Bulletins. 



Also included in this Bulletin are evaluations 

 of the Airborne Radiation Thermometer and the 

 Earth Resources Technical Satellite, both by 

 LTJG S. R. OSMER, USCG as Appendices C 

 and D, respectively.
