To understand the relationship among underice morphology, ice thickness and the structure of the oceanic boundary layer, an Autonomous Oceanographic Sampling Network is being developed. Each network consists of a base buoy and a number of Autonomous oceanographic Vehicles (AOVs) at fixed levels. The base buoy serves as a navigation beacon, energy source, telemetry link and surface sensor platform. Each AOV functions as a subsurface sensor platform, short term data logger and programmable, navigable vessel. Development of system components capitalizes on advanced microprocessors, navigation and communication systems developed by DOD and industry for buoy and vessel technology. The first step will be to produce an AOV that has acceptable performance as a subsurface platform and which can dock with the base buoy and conduct data exchange.
