Implication

Observational acoustic monitoring reveals a decline in underwater shipping noise during COVID-19, highlighting near real-time acoustic tracking of global trade slowdowns.

Key Points

To evaluate whether the economic impact and shipping traffic reductions caused by COVID-19 can be observed acoustically in near real-time.
Analyzed 100 Hz power spectral density from four bottom-mounted hydrophones via the Ocean Networks Canada observatory system.
Integrated hydrophone acoustic data with vessel Automatic Identification System (AIS) data and regional shipping trade statistics.
Median weekly noise power in the shipping frequency band decreased in alignment with the economic slowdown across three of the four hydrophone stations.
