2 OS43B-06 The ALOHA Cabled Observatory Fred K Duennebier, U. Hawaii Geology & Geophysics Mark D. Tremblay, Formerly with AT&T and TYCOM David Harris, U. Hawaii SEOST James Jolly, U. Hawaii SEOST David Copson, U. Hawaii SEOST William Doi, U. Hawaii SEOST James Babinec, U. Hawaii SEOST Roger Lukas, U. Hawaii Oceanography David Karl, U. Hawaii Oceanography

3 OS43B-06 The Retired Telecommunications Cable Opportunity Brief history of HOT and the cable re-use effort The ALOHA Cabled Observatory concept and design Installation Schedule

4 OS43B-06 More than 35,000 km of telecommunications cables installed since 1989 are being retired in the Pacific basin alone. Newer cables have far more bandwidth, rendering these systems obsolete for commercial use.

5 OS43B-06 Advantages of Cable Re-use High-bandwidth real-time data link to shore Considerable electrical power available Cables are installed and connected to the world Cable is free Utilizes highly reliable technology developed by the telecommunications industry for power and data transmission Existing systems likely to operate for at least 20 more years
