On Monday we completed our first successful test with multiple, free-drifting Mini-AUEs. This is a major milestone for the project as it marks the first time that the vehicles have been deployed and recovered in the field un-tethered. It is also the first time that multiple units have been deployed together. We released two units programmed to hold roughly a 6m depth while drifting for one hour off Torrey Pines Beach. We did three consecutive 1-hour deployments and all of the critical functions of the vehicles worked perfectly every time. Below are a few photos from the deployment and a example of preliminary data.
