Bubbles and Acoustic Communications Experiment (SPACE07): Acoustical and Physical Characteristics of Diffuse Bubble Plumes

Abstract

The scientific rationale for SPACE07 is that even though reliable underwater acoustic communication is central to the Navy's vision and Concept of Operations (CONOPS) for the future, and while significant progress in communications system development has been made in the last 15 years, current techniques fall far short of what is needed in terms of the data rates, the range of environments and operating conditions, and levels of covertness at which reliable communication links can be established. For example, communications in very dynamic environments (e.g., surface scattered environments in rough weather, communications at depth and speed for submarines) or at low SNRs as required for covert communications are areas where progress is still needed. To bridge the gap between current capabilities and future requirements, SPACE07 brings together a team of 10 investigators with world leading expertise in physical oceanography, underwater acoustics, signal processing, information theory and coding, practical modem development, Navy CONOPS and assets, and in the use of autonomous and distributed systems. The main goal of this project is to investigate the acoustical and physical characteristics of upper ocean bubble plumes from generation to dissolution, especially as they affect the acoustical environment. In-situ and remote acoustical measurements of bubbles, turbulence, surface waves and whitecaps will be combined with ACOMMS experiments run separately by Jim Preisig (WHOI) and Grant Deane's (Scripps) alpha -plume investigation, so as to permit direct integration of modeling and analysis. This particular project is a collaborative effort between the Institute of Ocean Sciences (Vagle) and University of Rhode Island (David M. Farmer).
