Buoyancy Controlled Micro Floats (ufloats) for Spatially Resolved Current Measurements

Abstract

Expeditionary deployments of autonomous ocean systems are often power limited by the capacity of their onboard batteries. Marine and hydrokinetic (MHK) resources have the potential to extend these missions, creating a strategic advantage to the US Navy. However, for current energy converters (CECs) or wave energy converters (WECs) to be effective, in situ resource characterization is required. The microFloat (pFIoat) platform offers a revolutionary approach to rapidly explore dynamic marine environments and collect valuable site data at a fraction the cost of traditional methods. With the swarm of drifters deployed in these environments, the tracks may be used to resolve large scale turbulent currents,
