Implication

Randomized trial demonstrates effective ship localization using distributed acoustic sensing in Norway, suggesting potential for marine traffic monitoring.

Key Points

  • This research aims to explore the effectiveness of distributed acoustic sensing for tracking ship movements and improving marine traffic safety.
  • Utilized a fiber-optic telecommunication cable for data collection in Trondheimsfjord, Norway.
  • Employed persistent homology to analyze continuous ship-generated acoustic signals.
  • Extracted direct arrival time curves to determine ship localization.
  • Detected ships located up to 1.6 km from the fiber, with high accuracy compared to AIS data.
  • Unidentified vessel not listed in AIS records was successfully detected.
  • Demonstrated the potential for real-time marine traffic monitoring to enhance situational awareness.
