Researchers have found that underwater canyons make strange noises louder. One sound, called the \u201cbiotwang,\u201d was first heard in 2014. It’s a 3.5-second call that was confirmed in 2018 to come from Bryde\u2019s whales.<\/p>\n
These whales make sounds from 30 Hz rumbles to 8,000 Hz metallic tones. This range is quite wide.<\/p>\n

<\/p>\n
Autonomous seagliders dive very deep to study these sounds. They track how sound moves through the ocean. This helps scientists understand whale movements.<\/p>\n
Researchers have linked 200,000 hours of recordings to whale movements. They found that whales are most active between February\u2013April and August\u2013November. The U.S. NOAA warns about dangers like vessel strikes. But, AI tools are now helping to protect these whales.<\/p>\n
By studying these sounds, scientists learn about the ocean’s soundscape. They find out how geology and biology shape it.<\/p>\n
Biotwang’s patterned pulses suggest social calls between whales. Even with more human noise, ocean sound research<\/em> keeps finding new clues. Like the Bio-Duck sounds from the 1980s, now linked to Antarctic minke whales.<\/p>\n Every discovery helps us understand life in Earth’s deepest trenches.<\/p>\n Scientists group mysterious marine sounds<\/em> into three types: biological, geological, and human-made. Whales like minke and humpback make complex calls. The Bio-Duck, a quacking sound, was first heard in 1982 in the South Fiji Basin.<\/p>\n It was linked to Antarctic minke whales. Studies now think bigger minke whales use these sounds to talk, but we can’t see them.<\/p>\n Earthquakes make low-frequency rumbles, and volcanoes send tremors that underwater noise detection<\/em> systems can pick up. The Bloop, a 1997 sound, was huge, spanning 5,000 km and matched with iceberg movements. Human activities, like seismic surveys, make very loud blasts, up to 240 dB, polluting 75% of Atlantic recordings.<\/p>\n Early studies by Ross Chapman in the 1980s used arrays to track sound directions. Today, we see patterns: humpbacks moan in winter, and finbacks send short pulses. Even the “Slow Down” signal\u2014a 7-minute frequency drop\u2014suggests there’s more to discover.<\/p>\n The Acoustical Society of America\u2019s 2024 meeting will share new findings. As technology gets better, we learn more about the ocean’s hidden language. This shows there’s much we don’t know yet.<\/p>\n Scientists have long been fascinated by oceanic acoustic phenomena<\/em> like the “Slow Down” sound from 1997. This deep-sea rumble was once thought to be a massive creature. But it was later found to be caused by an iceberg grounding.<\/p>\n Such discoveries show how sea sound mysteries<\/em> can turn into scientific breakthroughs. They start as puzzles and end as answers.<\/p>\n The Bio-Duck sound was first heard in 1960 but puzzled researchers until 2014. A team led by Ross Chapman found it came from Antarctic minke whales. These whales make repetitive clicks, which challenged the idea that the sound wasn’t biological.<\/p>\n Similar sounds have been heard off Australia and New Zealand. They suggest a global network of whale communication. This is a mystery that scientists are trying to solve.<\/p>\n In the Mariana Trench, the “biotwang” sound was discovered in 2014. Years later, researchers found it was made by Bryde\u2019s whales. These whales are 40\u201355 feet long and make unique warbles, mostly in groups.<\/p>\n The biotwang sound was more common during 2016\u2019s El Ni\u00f1o. This suggests that climate changes might affect their behavior. Over 200,000 hours of recordings have confirmed these patterns. But, scientists are left wondering about the purpose of these sounds.<\/p>\n These stories show how sea sound mysteries<\/em> are solved with determination. From icebergs to whales, each mystery solved leads to new ones. As technology improves, we can listen more closely to the ocean. Every strange noise might hold a clue to life’s hidden rhythms.<\/p>\n Advances in marine bioacoustics<\/em> and underwater sound analysis<\/em> are changing how scientists study ocean life. Today, tools can capture sounds from whale calls to distant earthquakes. They turn vast audio data into visual patterns.<\/p>\n Dr. Jessica Allen used Google\u2019s AI to analyze years of field recordings. This system turned raw audio into spectrograms, cutting analysis time from years to minutes. \u201cAI found sounds we\u2019d missed for decades,\u201d she says. It spots rare species like the \u201cbiotwang\u201d sound linked to minke whales.<\/p>\n Modern hydrophones, like those in NOAA\u2019s Pacific array, record 24\/7. They create a soundscape map of marine life. These devices cost around \u00a34,000 for year-long deployments.<\/p>\n By 2021, the Global Library of Underwater Biological Sounds (GLUBS) had over 4,000 recordings. It identified 21 species with 89.4% algorithm accuracy. Such precision helps track endangered populations, like blue whales, whose songs reveal migration routes and habitat stress.<\/p>\n Technology also addresses human impacts. Ship noise and seismic surveys disrupt animal communication, but AI now pinpoints these disturbances. The International Quiet Ocean Experiment (IQOE), active from 2015, uses passive sensors to monitor shipping lanes without disturbing ecosystems. By 2100, experts predict decoding dolphin communication\u2014a breakthrough fueled by AI\u2019s ability to parse complex vocal patterns.<\/p>\n Whales use sound to talk to each other from far away. Blue whales, for example, once called out to each other over 1,000 miles. Now, their calls only reach 100 miles because of human noise. This Pacific Ocean sounds<\/em> pollution messes with their feeding, mating, and migration.<\/p>\n Shipping lanes and seismic surveys make it hard for whales to be heard. Right whales now have to shout louder, by 10 decibels, near busy ports. Studies show mystery sounds of the ocean<\/em> like seismic air guns\u2014fired every 10 seconds\u2014can cut fish catches by 40-80% near survey zones. In 2008, narwhals in Arctic Canada were late migrating because of seismic testing noise.<\/p>\n Even small creatures are affected. Snapping shrimp, important for coral reefs, stop making noise when ships pass by. Scientists found the famous “Bloop” mystery sound came from Antarctic ice shifts. This shows how mystery sounds of the ocean<\/em> can uncover hidden worlds. Over 1,000 fish species and 100 invertebrates use sound to survive, but 90% of ocean species are unknown.<\/p>\n Hydrophones now map these vital soundscapes, showing how Pacific Ocean sounds<\/em> shape marine life. Saving these sound habitats isn’t just about whales. It’s about protecting the whole chorus of life in Earth’s biggest ecosystem.<\/p>\n From ancient myths to modern movies, unexplained ocean noises<\/em> have shaped our imagination. Sailors once thought eerie deep sea sounds<\/em> came from sea monsters or gods like Kanaloa. Greek legends told of sirens singing to lure ships.<\/p>\n These stories mixed fear and reverence for the unknown. They turned mystery into meaning.<\/p>\n Today, cultures find magic in ocean sounds. The “Bloop” sound in 1997 inspired movies and books. It shows how science and myth meet.<\/p>\n In Mexico\u2019s Caribbean reefs, the Listener sculpture records marine life sounds. It tracks ecosystem health. Colombia\u2019s Pacific communities celebrate coastal life with acapella chants, now UNESCO-protected.<\/p>\n Even today, underwater microphones spark curiosity. David Wolman\u2019s 2002 article linked sailors’ tales to today’s sound maps. From coral reef recordings to whale songs, these deep sea sounds<\/em> connect human stories across time.<\/p>\n As we unravel mysteries, art and science reimagine the sea’s voice.<\/p>\n Scientists use underwater acoustics<\/em> to study how human actions harm marine life. They track Bryde\u2019s whales to see how climate change changes their homes. These marine sound monitoring<\/em> tools show how migration and breeding patterns are shifting.<\/p>\n Shipping and energy projects make a lot of noise in the ocean. NOAA’s Ocean Noise Strategy aims to lessen this impact. They study long-term effects and create tools for decision-makers.<\/p>\n NOAA’s Cetacean Assessment Program counts whales and tracks endangered species like the Southern Resident killer whale. But, they face challenges. They need more data and better ways to measure. Improving underwater acoustics<\/em> and stricter rules could help protect marine life.<\/p>\n To protect marine life, we need to find a balance. By focusing on marine sound monitoring<\/em>, we can make quieter areas. This helps keep whales and other creatures safe as the ocean changes.<\/p>\n Now, anyone can join ocean sound research<\/em>. Scientists are inviting the public to help figure out mysterious marine sounds<\/em> through apps and online tools. \u201cIt used to be a coincidence,\u201d says marine biologist Allen, \u201cbut crowdsourcing lets everyone spot patterns.\u201d<\/p>\n Platforms like GLUBS let users analyze whale calls or track unexplained noises from the deep.<\/p>\n Schools and museums are turning classrooms into listening labs. Kids use hydrophones to record local waterways. Aquarium exhibits play real-time deep-sea audio. Over 250,000 marine species exist, yet only 1,000 fish and 100 invertebrates are known to make sounds\u2014leaving vast discoveries ahead.<\/p>\n \u201cThe ocean\u2019s voice connects us to its health,\u201d notes the UN Ocean Decade initiative. \u201cListening builds care.\u201d<\/p><\/blockquote>\n Starting in 2021, the UN\u2019s Ocean Decade has boosted projects linking art and science. The Ocean Agency\u2019s photo contests and JPI Oceans\u2019 sound festivals draw 70% more participants yearly, proving creativity sparks interest. When people hear a \u201cbiotwang\u201d or whale song, emotional bonds form\u2014Brennan (2018) found this triples conservation support.<\/p>\n Over 60% more volunteers now join acoustic surveys, showing how curiosity drives change. But only 15% of adults had engaged with ocean science before. By turning mystery into action\u2014like tagging humpback calls or tracking coral reef noise\u2014we all become guardians. The ocean\u2019s sounds aren\u2019t just data\u2014they\u2019re a call to protect its hidden worlds.<\/p>\n Scientists are exploring new ways to detect underwater noise<\/em> with AI-driven sensors. These tools might soon track whale migrations and changes in the climate by analyzing oceanic acoustic phenomena<\/em> in real time. As the planet warms, whales may have to travel longer distances to find food, changing their migration paths.<\/p>\n \n“AI models could connect data to climate factors and support protection efforts,” said Harrell. “These whales will have to travel farther as ocean patterns shift,” added Allen.\n<\/p><\/blockquote>\n New AI systems can sift through huge amounts of sound data to find hidden patterns. For instance, acoustic sensors can now check the health of coral reefs by comparing sound patterns from healthy versus damaged areas. Projects like ADEON II already use passive acoustics to study zooplankton migrations, combining sound with satellite data for better ecological insights. Miniaturized sensors could stay underwater longer, saving money and reducing environmental harm. Despite challenges like high costs and regulatory hurdles, advancements in energy-efficient tech are making progress. Researchers also want to explore areas like under-ice regions and trench ecosystems.<\/p>\n By linking sound data with temperature and salinity measurements, scientists hope to forecast ecosystem changes years ahead. The SOFAR channel\u2019s ability to transmit sound over long distances is also being studied. This could help monitor seismic activity and underwater volcanoes, leading to new geological discoveries.<\/p>\n The ocean’s mystery sounds fascinate scientists and curious people. NOAA researchers found “bio-duck” quacks from Antarctic minke whales. The Bloop remains a puzzle, showing how much we don’t know.<\/p>\n For decades, scientists have used hydrophones and satellite data to solve some mysteries. But, the deep ocean is full of secrets waiting to be uncovered.<\/p>\n NOAA\u2019s hydrophone arrays and NASA\u2019s Argo probes help us understand ocean sounds and climate changes. Even as the surface warms, the deep ocean stays cool. This shows how sound monitoring helps track the environment.<\/p>\n Discoveries like the bio-duck’s origin show how curiosity leads to progress. But, there are many more mysteries to solve. Minke whales’ communication patterns are not fully understood, making it hard to access icy habitats.<\/p>\n Olaf Meynecke said exploring these sounds connects human wonder with conservation. Each sound gives us clues about marine life and climate health. Public interest helps fund studies, ensuring we keep exploring.<\/p>\n Protecting these soundscapes is key to saving ecosystems and our planet. Whether it’s listening to whales or tracking warming trends, we must pay attention. By embracing these mysteries, we celebrate science and Earth’s wonders. The next step is to listen and act.<\/p>\n","protected":false},"excerpt":{"rendered":" The ocean is full of secrets, with strange noises echoing in its depths.
