On-Demand, Continuous Eelgrass Monitoring

, a new moon pool has been introduced, allowing the sensor to be mounted vertically, with just the sensor cage and probes below the hull.  A copper mesh around the probe cage will slow fouling and prevent weed from entering the cage.Communications: The cell coverage in DKP is excellent, and the cellular network was an ideal solution. For the scientists, the mission was a first step at using a moving sensor on an unmanned vessel in a large, complicated embayment.Data: The YSI sensor and the SeaTrac ASV provided a successful combination to collect water quality data.  Being able to monitor
