Direct observation of sea ice in the Arctic poses many challenges, as satellite sensors cannot detect the fine fractal structure of ice.
Observing through human-crewed ships in these areas is also difficult due to weather conditions and floating broken ice.
A New Autonomous Monitoring System
To successfully track the impact of melting Arctic ice on ecosystems and the planet, FAU researchers have created an alternative monitoring system. This system can improve the autonomy of marine vehicles, aid maritime missions, and provide insights into how melting ice is affecting the marine ecosystem.
Their product features a small waterplane area twin hull (SWATH) vessel that acts as a docking and charging station for AUVs and UAVs. The SWATH ship is stable, allowing for navigation through melting ice and operation in various sea conditions.
Advanced Technology for Ice Monitoring
The UAVs use high-resolution cameras and sensors for mapping and navigation, while the AUVs gather underwater data. The DJI Dock 2 system enables UAVs to autonomously land, recharge, and redeploy, while an advanced underwater docking system allows AUVs to refuel and transfer data, extending their range.
Survey instruments in the underwater hulls collect mission-specific data, which is processed onboard and transmitted via satellite. This enables long-term, unmanned ocean monitoring.
Sustainable Power for Continuous Monitoring
The system is designed to handle high wind speeds and serves as a self-sustaining platform. Wind energy will support sailing in Arctic waters, while an underwater turbine will generate power to sustain the system’s operations.
Using the motion of a wind-driven sailboat to generate power from the turbine beneath the SWATH can support long-term Arctic Ice Melting Monitoring missions.
A Breakthrough for Arctic Research
“Our proposed autonomous observation platform system offers a comprehensive approach to studying the Arctic environment and Arctic Ice Melting Monitoring,” said Tsung-Chow Su, senior author and a professor in FAU’s Department of Ocean and Mechanical Engineering. “Its design and capabilities make it well-suited to overcome the challenges of the Arctic’s unique conditions. By providing a self-sustaining platform for continuous data collection, this design supports scientific research, environmental protection, and resource management, laying the foundation for year-round Arctic Ice Melting Monitoring.”
