Glider applicationsGlider applications
• Climate/modelsClimate/models
• HABsHABs
• Biogeochemical cyclesBiogeochemical cycles
• Ocean acidification/hypoxiaOcean acidification/hypoxia
• Internal tides/sediment resuspensionInternal tides/sediment resuspension
CeNCOOS region “feels” large scale/global variations in climate
Gliders good tools to track variations in climate, feed models

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 .

CO2 pH
Very large gradients (as large as global means) observed on order of a
kilometer

A Spectrum of Vehicles
Late ’90s>500 kgCarry many sensors at 1.5 m/s, but only lasts on order a day.
Early ’00s48 kgCan run for months, but can only carry a few sensors, and goes quite slowly (0.3 m/s).
2011100 kgMultiple operation modes>1000 km at 1 m/s>3000 km at 0.5 m/s>1 month
