Research is ongoing concerning the
species and habitats most at risk to anthropogenic underwater sound and what
frequencies, intensities, and duration of sounds pose an unacceptable level of
impact. Compiling and summarizing this
information could provide a useful tool for researchers, government agencies,
and non-governmental groups to better understand the problem and potential
solutions. This evaluation could
• Assessment of sounds related to marine transportation.
• Marine shipping’s contribution to underwater sound.
• Global models to predict ocean noise and its source.
• Areas such as ports and shipping lanes where shipping could be adding
an unacceptable level of sound.
• Ways to mitigate shipping noise, including propeller cavitation,
without compromising safety and efficiency.
Including operational considerations (e.g., changes in cruising speed)
• Long-term, large-scale noise monitoring in the ocean.
• Characterization of noise features based on location and environment
• Collection and integration of existing datasets through a national
network to share data on marine sound, using social media and innovative,
modern means for expanding the size of and access to data.
• Cost-effective target-of-opportunity measurements of individual ships
using existing and planned networks of underwater sensors in conjunction with
AIS and other ancillary data sources.
• Response of certain species to vessel traffic using telemetry and
other remote sensing methods.
