Underwater vehicles are utilized in various applications including underwaterdata-collection missions. The tethered connection constrains the mission bothin distance traveled and number of vehicles that can run in the same area,while the addition of acoustic communications onto the vehicles grants themseveral functionalities. However, due to the low bandwidth of the underwateracoustic channel-which leads to low data rates-and the time overhead imposed byboth the channel propagation delay and the processing delay by the acousticmodems, efficient protocols are required. In this paper, an implicitdata-compression and transmission protocol is proposed to carry outenvironmental monitoring missions such as adaptive sampling of physical andchemical parameters in the water. In a semi-autonomous manner between thevehicle and the control center, both sides keep silent in data transmission aslong as they can estimate and predict the actions of the other side, unlessenvironmental data and/or kinematic data are found to be unpredictable. Ourdesign puts the human in the loop to send high-level control commands.Experiments were conducted using an autonomous vehicle with WHOI micro-modemsin the Raritan River, Somerset, Carnegie Lake in Princeton, and in the MarinePark in Red Bank, all in New Jersey.
