Welcome to the RUCOOL autonomous underwater gliding vehicle (AUGV) home page. The Slocum Coastal Electric Glider (Webb Research Company, Falmouth, MA, Figure 1) is an autonomous underwater vehicle that converts changes in vehicle buoyancy to vertical motion. A pair of fixed wings provides forward momentum to move horizontally through the ocean. While the majority of the glider is reserved for glider mechanics, battery storage and communication equipment, a section is devoted exclusively to scientific payload. A suite of miniaturized physical and bio-optical instruments, which measure in situ water properties including temperature, salinity, and the absorption and scattering of light in the water column, have been and are currently under development for placement in the glider’s science payload bay
