CeNCOOS Glider Activities Francisco Chavez Senior Scientist Monterey Bay Aquarium Research Institute
Glider/AUV Activities • 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 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 Liquid Robotics on payloads for Wave Glider • Work with MBARI on AUV developments
Glider applications • Climate/models • HABs • Biogeochemical cycles • Ocean acidification/hypoxia • Internal tides/sediment resuspension
CeNCOOS region “feels” large scale/global variations in climate Gliders good tools to track variations in climate, feed models
Glider deployment strategies • Continuous (lines – how long, grids – scale) • Process experiments • Rapid response
Existing and proposed glider operations In support of climate change, modeling, process studies, HABs, etc. data in near real time
MBARI Ocean Acidification (OA) mooring – NSF support . Wave Glider equipped with the same OA sensors
Satellite sea surface temperature Upwelling Relaxation
Very large gradients (as large as global means) observed on order of a kilometer CO2 pH Atmosphere Wave glider observations of pCO2 and pH
A Spectrum of Vehicles 2011 100 kg Multiple operation modes >1000 km at 1 m/s >3000 km at 0.5 m/s >1 month Late ’90s >500 kg Carry many sensors at 1.5 m/s, but only lasts on order a day. Spray Early ’00s 48 kg Can run for months, but can only carry a few sensors, and goes quite slowly (0.3 m/s). LRAUV Jim Bellingham, MBARI

Future • 2012 – samplers for particles and water, adaptive sampling, patch budgets Under development by MBARI (Scholin, Bellingham) now Long range AUV
