The hope today was to do prolonged UAV tests while simultaneous AUV operations with T-REX. On reaching the outskirts of the Setubal channel rely by 10am, the Xtreme 2 AUV with T-REX was deployed immediately.

With the week's hectic activities onboard the Bacamarte and at the Alfeite Navy base in the evenings (and often late at night), the PIs decided that it was wise to give everyone a break and 'stand down' for the day.

Repeated sidescan and multi-beam surveys to find dummy packages and 'Oscar' for the maritime authorities failed till the third try. To acquires these targets we slowed down the Noptilus AUV to 0.5 m/s to get higher resolution with more data points. Third time was the lucky one.

On Wednesday July 10th, the AUV team split to preform varying operations in the harbor as also further away from shore.
