Life on land could have quieted down through the top of the pandemic, however far offshore the Atlantic Ocean was simply as lively as ever based on a brand new examine from the College of New Hampshire. Researchers discovered that there was no vital change within the continental shelf’s underwater soundscape through the 12 months 2020 — a shocking distinction to earlier studies of quieter coastal waters throughout that very same timeframe.
“It is fascinating that oceans are so dynamic and variable; completely different areas actually have completely different personalities based mostly on the pure and human interactions that occur inside these waters,” mentioned Jennifer Miksis-Olds, analysis professor and director of UNH’s Middle for Acoustic Analysis and Training.
Within the examine, just lately printed within the Journal of the Acoustical Society of America Categorical Letters, researchers targeted on seven offshore websites geographically spanning the Outer Continental Shelf from Virginia to Florida — locations the place hydrophones had been positioned on the seabed in 2017 after which retrieved in 2021 as a part of UNH’s Atlantic Deepwater Ecosystem Observatory Community. The info indicated that though the sound produced from industrial delivery vessels decreased, there was a rise in sound from different vessels, like fishing boats and pleasure crafts. The online consequence: no main distinction within the underwater soundscape roughly 45-280 miles from the shoreline.
“Having that long-term time sequence was actually essential as a result of it allowed for direct comparability of years of knowledge earlier than COVID-19 hit,” mentioned Miksis-Olds. “Acoustic measurements within the deep ocean are extra scarce than in coastal waters, so this analysis gives one other perspective on how the deep oceans had been impacted — or not — by COVID-19.”
Researchers acknowledge that the findings are in direct distinction to different research targeted on waters nearer to the shoreline however say that is why it is necessary to look at completely different facets of the ocean setting earlier than drawing any conclusions.
The analysis was supported by the U.S. Division of the Inside and the Bureau of Ocean Power Administration in partnership with the Workplace of Naval Analysis and NOAA.
