Glider/AUV Activities Spray glider continuously along CalCOFI Line 67 in collaboration with Davis and Rudnick –Scripps Spray glider continuously along CalCOFI Line 67 in collaboration with Davis and Rudnick –Scripps Support deployments of 2 NPS Spray and 1 Webb glider – time and data available to CeNCOOS Support deployments of 2 NPS Spray and 1 Webb glider – time and data available to CeNCOOS Support deployments of 2 UCSC Webb gliders – time and data available to CeNCOOS Support deployments of 2 UCSC Webb gliders – time and data available to CeNCOOS Work collaboratively with Teledyne-Webb on development of deep gliders – data collected available to CeNCOOS Work collaboratively with Teledyne-Webb on development of deep gliders – data collected available to CeNCOOS Work collaboratively with Liquid Robotics on payloads for Wave Glider Work collaboratively with Liquid Robotics on payloads for Wave Glider Work with MBARI on AUV developments Work with MBARI on AUV developments

3. Glider applications Climate/models Climate/models HABs HABs Biogeochemical cycles Biogeochemical cycles Ocean acidification/hypoxia Ocean acidification/hypoxia Internal tides/sediment resuspension Internal tides/sediment resuspension

4. CeNCOOS region “feels” large scale/global variations in climate Gliders good tools to track variations in climate, feed models

5. Glider deployment strategies Continuous (lines – how long, grids – scale) Continuous (lines – how long, grids – scale) Process experiments Process experiments Rapid response Rapid response

6. Existing and proposed glider operations In support of climate change, modeling, process studies, HABs, etc. data in near real time

11. MBARI Ocean Acidification (OA) mooring – NSF support. Wave Glider equipped with the same OA sensors

12. Upwelling Relaxation Satellite sea surface temperature

13. Upwelling as observed from wave glider

14. Relaxation as observed from wave glider

15. CO 2 pH Very large gradients (as large as global means) observed on order of a kilometer Wave glider observations of pCO 2 and pH Atmosphere

16. A Spectrum of Vehicles Late ’90s >500 kg Carry many sensors at 1.5 m/s, but only lasts on order a day. Early ’00s 48 kg Can run for months, but can only carry a few sensors, and goes quite slowly (0.3 m/s). 2011 100 kg Multiple operation modes >1000 km at 1 m/s >3000 km at 0.5 m/s >1 month LRAUV Spray Jim Bellingham, MBARI
