1. Hawaii Ocean Time-series and the ALOHA Observatory Roger Lukas University of Hawaii ALOHA Observatory Review February 2006

2. Surface layer forced by seasonal, interannual and decadal variations of atmosphere … Decadal salinity variation in upper pycnocline remotely forced … Main pycnocline exhibits 15-year long trend One of many significant results from HOT

3. Last two years Continued ~monthly cruises to Station ALOHA … 17+ years! WHOTS mooring deployed August 2004 (Weller/Lukas) redeployed July 2005 MOSEAN mooring deployed August 2004 (Dickey/Karl) Seaglider surveys (Emerson/Eriksen)

4. Next 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

5. 6 nm ALOHA Observatory Management Issues MOSEAN (NOPP) Ocean Reference Station (NOAA/NSF) HAW-4 connection UW/APL profiling mooring ISSUES Mechanical interference, including deployments and recoveries Acoustic interference (releases, ADCPs, etc.) Sediment trap mooring?? Drifting sediment traps?? http://kela.soest.hawaii.edu/ALOHA

6. Action 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
