Two Vehicles Better Than One?

The submersible Alvin and the autonomous underwater vehicle Sentry are among the most advanced underwater research tools available. To make the most of limited ship time, scientists sometimes use the two vehicles together. By night Sentry makes maps of the seafloor. By day, researchers and Alvin pilots use the maps to explore target areas. WHOI engineer Kaitlyn Tradd (left) will describe a recent Alvin-Sentry cruise to the Gulf of Mexico and the logistics and intricacies of such tandem operations tomorrow afternoon in the Ocean Science Exhibit Center as part of the Science Made Public lecture series.
