原始语种摘要: This paper revisits Stommel's vision for a global glidernetwork and the Argo design specification. A concept of floats with wings,so-called slow underwater gliders, is explored. An analysis of theenergy or power consumption shows that, by operating gliders with half thevehicle volume at half the speed compared to present gliders, the energyrequirements for long-duration missions can be met with available batterycapacities. Simulation experiments of slow gliders are conducted using thehorizontal current fields from an eddy-permitting ocean reanalysis product.By employing a semi-Lagrangian, streamwise navigation whereby the glidersteers at right angles to ocean currents, we show that the concept isfeasible. The simulated glider tracks demonstrate the potential forefficient coverage of...
