(Orcutt et al., 2000). Significant engineering advancements have also been made in the development of technologies for autonomous underwater vehicles (AUVs), which are pro- grammable, robotic vehicles that can drift, drive, or glide through the ocean without real-time control by human op- erators. AUVs rely on acoustic signals for navigation and communication when submerged. Use of acoustic signals for the precise localization of Seagliders has been proposed for use in tomography experiments and for extending the use of AUVs to ice-covered environments. Research in acoustic communication systems has resulted in improved perfor- mance and robustness spurred on by applications in marine research, oceanography, marine commercial operations, the offshore oil industry, and defense. Finally, the proliferation of small omnidirectional and directional sensing nodes with high-endurance recorders has made making ocean acoustics measurements more assessable.
The ocean is one of the most challenging environments in which to work and conduct research due to the harsh physical conditions affecting both people and equipment. The ocean is also one of the most expensive natural laboratories due to the costs of ships, equipment, and personnel to run them. The membership of the TCUW is made up of a collection of individuals who endeavor to take on this challenging envi- ronment. They come from a wide variety of backgrounds, in- cluding physics, mathematics, geophysics, oceanography, and engineering, and they conduct work in both basic research and applied programs. Perhaps most importantly, the TCUW has a collegial, welcoming, and supportive atmosphere. It is an environment where students and young investigators are encouraged and given opportunities to become involved in theTCaswellasintheASAasawhole.

A full description of the research activities conducted by the members of the TCUW is too extensive to be contained within a single article. The summary provided herein is meant to present the general scope of the of the breadth of research conducted by the TC. Furthermore, the members of the TCUW are also active in research associated with oth- er TCs. There is strong overlap between the TCUW and the TC on Acoustical Oceanography, and many members of the TCUW are also involved in the TCs on Physical Acoustics, Signal Processing, and Animal Bioacoustics. Additionally, the membership of the TCUW is also well represented on the Administrative Committees of the Acoustical Society of America (ASA).
