An Autonomous Underwater Vehicle (AUV) will be used to increase the spatial resolution of water quality and current mapping in neashore areas between the permanent buoy stations. Missions of up to 7 hours can be completed for detailed resolution mapping. The vehicle is controlled by user-specified pre-configured mission tracks that are driven by GPS navigation through Wi-Fi communication. The water quality instrumentation onboard the YSI AUV is the same as that used on the mainframe permanent buoys. In addition, a side-scan imaging sonar and a 6 and 10 beam Doppler Velocity Log (DVL) allow for sediment and bottom classification and characterization and current profiling, respectively. []
