Ice-Ocean Four Dimensional Structure and Dynamics.

Abstract

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 The purpose of the network is to provide a technique for spatially adaptive sampling capable of resolving evolving gradients with sparsely distributed sensors. Each network consists of a base buoy and a number of Autonomous Oceanographic Vehicles (AUVs) at fixed levels. The base buoy serves as a navigation beacon, energy source, telemetry link and surface sensor platform. Each AUV functions as a subsurface sensor platform, short term data logger and programmable, navigable vessel. The first step has been to use an AUV to define acceptable performance as a subsurface platform, to implement and evaluate schemes/systems for homing and docking with the base buoy, and to conduct tests of the data and power transfer interfaces.
