Next year or soNext year or so
• WHOTS mooring redeployment June 2006
• MOSEAN mooring redeployments
• UH Seagliders (2)• ALOHA cabled observatory
installation• Observatory management issues
– physical layout, logistics– cyberinfrastructure– governance
• Moored profiler to MARS for initial deployment
UW/APL real-time cabled profiling mooring

Action ItemsAction Items
•Current funding for HOT ends November 2008; new proposals required
•Support for moving moored profiler to ALOHA needed
•Observatory management support needed
•Protocols, costs and timelines for experiment planning[e.g. benthic community videography (Smith and Drazen, UH)] need to be published
