Using recordings from MBARI's deep-sea hydrophone, marine-mammal researchers have found that the sounds of seal bombs could have significant impacts on the behavior of harbor porpoises in and around Monterey Bay. Seal bombs ...

Measuring noise reduction in the ocean during the pandemic

For decades, it has been assumed that a quieter ocean could help take the Salish Sea's southern resident killer whales off the endangered species list. But researchers lacked enough data to test this theory—until now.

Seismic sensors record hurricane intensity, study finds

The earth is a noisy place. Seismometers, which measure ground movements to detect earthquakes, volcanic eruptions, and manmade explosives, are constantly recording smaller vibrations caused by ocean waves, rushing rivers, ...

Assessing noise in Southern California whale habitat

A new study assessing the underwater soundscape off Southern California found that blue, fin and humpback whales experience a range of acoustic environments, including noise from shipping traffic as well as quieter areas ...

New international standards needed to manage ocean noise

As governments and industries expand their use of high-decibel seismic surveys to explore the ocean bottom for resources, experts from eight universities and environmental organizations are calling for new global standards ...

Worldwide ship traffic up 300 percent since 1992

Maritime traffic on the world's oceans has increased four-fold over the past 20 years, likely causing more water, air and noise pollution on the open seas, according to a new study quantifying global ship traffic.
