Surface drifting buoys mark the original search datum for search and rescue missions. this buoy will be self-locating, using gps and transmit its location every 12 hours via the goes satellite for 45 days. the system design will be specified as a result of this proposal.

There is a growing interest in small, high speed autonomous underwater vehicles (auv's). in particular, the u. s. navy submarine force could greatly enhance its soft and hard kill capabilities as well as detection and classification capabilities through the effective utilization of such devices.… More

The proposed effort will investigate the technical feasibility, system requirement, performance specification, and cost of an expendable ocean sensor system to measure several important environmental parameters. the ability to make these measurements quickly, accurately, and at low cost impacts a… More

There is a growing interest in obtaining environmental dta in the littoral environment. In particular, Acoustic and non-acoustic surveillance systems require concurrent or recent environmental data from the immediate area of interest for accurate system performance prediction due to the spatial and… More
