Description The U.S. Geological Survey (USGS) obtained oceanographic measurements as part of the Office of Naval Research (ONR) Optics Acoustics and Stress In Situ (OASIS) Project. The objective of this work is to relate optical and acoustic properties of suspended particles as a function of particle size, concentration, and vertical distribution near the sea floor. In order to accomplish this task, a specially modified tripod allows vertical profiling near the sea floor by moving instruments up and down within 2 meters of the sea floor. The profiling arm was designed and built by a team of scientists, engineers and technicians from the USGS Woods Hole Coastal and Marine Science Center (WHCMSC). To accommodate communications and provide power required for arm movement and control, the tripod was connected via underwater cable to the Martha's Vineyard Coastal Observatory (MVCO), operated by Woods Hole Oceanographic Institution (WHOI). In addition to the instruments on the profiling arm, other instruments were mounted elsewhere on the static portion of the tripod and nearby on a nearby seafloor platform. The tripod (USGS Mooring 910) and seafloor platform (911) were deployed on September 17, 2011 at the MVCO 12-m deep underwater node which is about 2 kilometers (km) south of Martha's Vineyard, Massachusetts. Divers assisted in the deployment and cleaned the acoustic and optical instrument faces on the tripod approximately once a week until recovery on 23 October, 2011.
