The goal of this project is to complete the development and field demonstration of an affordable, easy to use technology for the real time collection and dissemination of data from instruments deployed in the coastal ocean. The observing system that has been developed consists of four elements a low-cost acoustic data link that transfers data from instruments on the bottom or in the water column to a nearby surface buoy, a lightweight, easy to deploy surface buoy and mooring, a radio modem to send data to shore, and an internet-based automatic data distribution and display system. The project is being conducted cooperatively with the U.S. Geological Survey, Woods Hole Oceanographic Institution, RD Instruments, the Massachusetts Water Resources Authority, and the U.S. Coast Guard. This project is a follow-on to the project titled Low Cost Modular Telemetry for Coastal Time- Series Data which resulted in the development and demonstrnflon of an acoustically linked coastal data collection system. The system was deployed for four extended periods and most elements perloned very well however, the acoustic link was not as robust as expected. The objectives of the present project are to fully implement the new low cost transmifler hardware and software to improve the acoustic perfbnance, to demonstrnte the system with muhiple subsurface instrrnents, and to improve the automated data distribution system.
