Plan for global reference library of aquatic noises to monitor & study marine life

Global Library of Underwater Biological Sounds, “GLUBS,” will help monitor changing marine life

INTRO: Of the roughly 250,000 known marine species, scientists think all ~126 marine mammals emit sounds – the ‘thwop’, ‘muah’, and ‘boop’s of a humpback whale, for example, or the boing of a minke whale. Audible too are at least 100 invertebrates, 1,000 of the world’s 34,000 known fish species, and likely many thousands more.

Now a team of 17 experts from nine countries has set a goal of gathering on a single platform huge collections of aquatic life’s tell-tale sounds, and expanding it using new enabling technologies – from highly sophisticated ocean hydrophones and artificial intelligence learning systems to phone apps and underwater GoPros used by citizen scientists.

The Global Library of Underwater Biological Sounds, “GLUBS,” will underpin a novel non-invasive, affordable way for scientists to listen in on life in marine, brackish and freshwaters, monitor its changing diversity, distribution and abundance, and identify new species. Using the acoustic properties of underwater soundscapes can also characterize an ecosystem’s type and condition.

The team’s paper, “Sounding the Call for a Global Library of Biological Underwater Sounds,” is published in the journal Frontiers in Ecology and Evolution.

Says lead author Miles Parsons of the Australian Institute of Marine Science: “The world's most extensive habitats are aquatic and they’re rich with sounds produced by a diversity of animals. With biodiversity in decline worldwide and humans relentlessly altering underwater soundscapes, there is a need to document, quantify, and understand the sources of underwater animal sounds before they potentially disappear.”

The team’s proposed web-based, open-access platform will provide... (MORE - details, sound files, info)

Plan for global reference library of aquatic noises to monitor & study marine life

INTRO: From the “boing” of a minke whale to the “drum” of a red piranha, scientists are documenting more sounds in our world’s oceans, rivers and lakes every year. Now, a team of experts wants to go a step further and create a reference library of aquatic noise to monitor the health of marine ecosystems.

The Global Library of Underwater Biological Sounds, “Glubs”, will include every “thwop”, “muah” and “boop” of a humpback whale as well as human-made underwater sounds and records of the geophysical swirl of ice and wind, according to a paper in the journal Frontiers in Ecology and Evolution.

Of the roughly 250,000 known marine species, scientists think all 126 mammals emit noise. At least 100 invertebrates and 1,000 of the world’s 34,000 known fish species are known to make noise, but experts believe many more sounds are waiting to be discovered and identified.

By bringing together existing libraries of fish, frogs and other marine species, it is hoped the library will help identify the lullabies, chants and anthems of aquatic ecosystems. Some fish species appear to develop geographic dialects, while the calls of blue whales are known to evolve through time.

“The world’s most extensive habitats are aquatic, and they’re rich with sounds produced by a diversity of animals,” says lead author Miles Parsons of the Australian Institute of Marine Science. “With biodiversity in decline worldwide and humans relentlessly altering underwater soundscapes, there is a need to document, quantify and understand the sources of underwater animal sounds before they potentially disappear.” (MORE - details)
