Overview

Observational analysis reveals underwater noise from ships using distributed acoustic sensing, highlighting its benefits over traditional systems.

Key Points

  • Large ships are detectable in DAS data over 10 km at frequencies between 10-90 Hz.
  • Data collection utilized 4 days of DAS data from the Ocean Observatories Initiative in November 2021.
  • Automatic Identification System information was used to identify ship signals in the DAS data.
  • DAS technology shows promise, complementing traditional hydrophone systems for marine acoustic monitoring.
