A Marine Growth Detection System for Underwater Gliders

Marine growth has been observed to cause a drop in the horizontal and vertical velocities of underwater gliders, thus making them unresponsive needing immediate recovery. Currently, no strategies exist correctly identify onset marine for gliders only limited data sets biofouled hulls exist. Here, field test conducted first investigate impact on dynamics power consumption then design an anomaly detection system high levels biofouling. A Slocum glider was deployed eight days with drag stimulators imitate severe biofouling; then, vehicle redeployed additions hull further 20 days. The mimicked biofouling caused speed reduction due significant increase drag. Additionally, lower causes steady-state flight stage last longer rudder become less responsive; hence, results shortening deployment duration through consumption. As actual p. pollicipes occurred during second deployment, it is possible develop that successfully detects identifies glider, blending model- data-based solutions using data. will greatly help pilots replan missions safely recover if detected.
