Dolphin and Whale News ArticlesExcerpts of key news articles on dolphins and whales
Two dolphins have been recorded having a conversation for the first time after scientists developed an underwater microphone which could distinguish the animals' different "voices". Researchers have known for decades that the mammals had an advanced form of communication. But scientists have now shown that dolphins alter the volume and frequency of pulsed clicks to form individual "words" which they string together into sentences in much the same way that humans speak. Researchers at the Karadag Nature Reserve, in Feodosia, Ukraine, recorded two Black Sea bottlenose dolphins, called Yasha and Yana, talking to each other in a pool. Each dolphin would listen to a sentence of pulses without interruption, before replying. Lead researcher Dr Vyacheslav Ryabov, said: "Essentially, this exchange resembles a conversation between two people. "Each pulse represents a phoneme or a word of the dolphin's spoken language. "The analysis of numerous pulses registered in our experiments showed that the dolphins took turns in producing [sentences] and did not interrupt each other, which gives reason to believe that each of the dolphins listened to the other's pulses before producing its own. "This language exhibits all the design features present in the human spoken language. This indicates a high level of intelligence and consciousness in dolphins. Their language can be ostensibly considered a highly developed spoken language, akin to the human language."

My research team and I were following a school of bottlenose dolphins near shore ... off Los Angeles, California. The dolphins were still feeding in circle near shore, when suddenly, one individual changed direction heading out toward deeper water. A minute later, the rest of the school turned to follow. Seeing them abruptly leave a foraging ground and change direction came as a surprise to the research team. I decided to follow them. The dolphins increased their speed. Somewhere near three miles offshore the dolphin group stopped, forming a sort of ring around a dark object in the water. “Someone’s in the water!” yelled my assistant, standing up and pointing at the seemingly lifeless body of a girl. As the boat neared, she feebly turned her head toward us, half-raising her hand as a weak sign for help. If we didn’t act immediately, the girl would die. We [pulled] the frail and hypothermic body on board. “She is cyanotic,” said one of my researchers, also a lifeguard, after a cursory examination. “She has severe hypothermia. We need to get her warm!” We managed to get some of her wet garments off and wrap her in a blanket. We took turns keeping her warm by huddling with her under the blanket. A couple of hours later, we were all waiting outside the emergency room at the Marina del Rey hospital. The ER doctor came out to talk with us. The girl, it seems, would pull through, and he thanked us for our quick action. He tells us the girl was vacationing in L.A. from Germany and, as the letter found in her plastic bag explained, she was attempting suicide. If we hadn’t found her, if the dolphins hadn’t led us offshore when they did, to that specific place, she would have died.

They escape from aquarium tanks. They locate underwater mines. Now, a new paper published in the journal Proceedings of the National Academy of Science claims that dolphins recognized their own name when called. Vincent Janik, one of the authors of the study and a biology researcher at the University of St. Andrews in Scotland, said that the name is actually a specific type of dolphin vocalization that the animals respond to. "They're these high pitched whistles that have a little bit of a melody," he told ABC News. These sounds are referred to as "signature whistles." Janik and his colleague, Stephanie King, cruised along the east coast of Scotland looking for bottlenose dolphins. After spotting and identifying a dolphin in the wild, the researchers would play one of three different sounds: a modified sound clip of that dolphin's signature whistle, a signature whistle of one of its podmates, or the signature whistle of a completely foreign dolphin. They played the dolphin's own signature whistle and the animal would come up and approach the boat and whistle back. However, the dolphin didn't respond to the other two types of whistles and mostly kept about its business. It may seem odd that the dolphins don't react much to the whistles of their fellow herdmates, but Janik says that copying a dolphin's signature whistle just right is part of their social group. "This copying only occurs between closely associated animals, like between mothers and their calves," he said. Dolphins only need to respond to their own signature whistles, since any socially relevant animal will have learned how to copy it. "It says to them, 'I know that this [whistle] is a friend.'"
Whales flee from the loud military sonar used by navies to hunt submarines, new research has proven for the first time. The studies provide a missing link in the puzzle that has connected naval exercises around the world to unusual mass strandings of whales and dolphins. Beaked whales, the most common casualty of the strandings, were shown to be highly sensitive to sonar. But the research also revealed unexpectedly that blue whales, the largest animals on Earth and whose population has plummeted by 95% in the last century, also abandoned feeding and swam rapidly away from sonar noise. The strong response observed in the beaked whales occurred at noise levels well below those allowed for US navy exercises. "For whales and dolphins, listening is as important as seeing is for humans – they communicate, locate food, and navigate using sound," said Sarah Dolman, at charity Whale and Dolphin Conservation. "Noise pollution threatens vulnerable populations, driving them away from areas important to their survival, and at worst injuring or even causing the deaths of some whales and dolphins." Dolman said there were no accepted international standards regarding noise pollution and there was an urgent need to re-evaluate the environmental impacts of military activities. Unusual mass strandings, where multiple species of whale and dolphin beach at several locations at once, have soared since the introduction of military sonar in the 1950s and can be fatal. The strandings occur every year and major recent events saw up to 15 animals beached in the Canary Islands, the Bahamas and Greece.

The ocean depths have become a noisy place. The causes are human: the sonar blasts of military exercises, the booms from air guns used in oil and gas exploration, and the whine from fleets of commercial ships that relentlessly crisscross the global seas. Marine experts say the rising clamor is particularly dangerous to whales, which depend on their acute hearing to locate food and one another. To fight the din, ... the National Oceanic and Atmospheric Administration seeks to document human-made noises in the ocean and transform the results into the world’s first large sound maps. “It’s a first step,” Leila T. Hatch, a marine biologist and one of the project’s two directors, said of the sound maps. “No one’s ever done it on this scale.” Michael Jasny, a senior policy analyst with the Natural Resources Defense Council, [which] has sued the Navy to reduce sounds that can harm marine mammals, praised the maps as “magnificent” and their depictions of sound pollution as “incredibly disturbing.” Legal experts say the new findings are likely to accelerate efforts both domestically and internationally to deal with the complicated problem through laws, regulations, treaties and voluntary noise reductions. The Navy estimates that blasts from its sonars — used in training and to hunt enemy submarines — result in permanent hearing losses for hundreds of sea mammals every year and temporary losses for thousands. All told, annually the injured animals number more than a quarter million.

Environmental groups sued the Obama administration ... for granting the Navy permits to test underwater sonar along the West Coast -- and potentially harass up to 650,000 porpoises, seals, dolphins and whales over a five-year period. The alliance said it wasn't seeking to stop the testing but to scale it back, especially at certain times and in waters important for feeding and giving birth. Several studies have found that marine mammals can hear low-frequency sonar, which is magnified under water, and periodically dolphins and even whales have been found with perforated ear drums. The National Marine Fisheries Service "fell down on the job and failed to require the Navy to take reasonable and effective actions to protect" marine mammals, Steve Mashuda, an attorney for the law firm Earthjustice, said. The lawsuit ... claims that the Navy's sonar use might be strong enough to kill the animals outright. But even if it doesn't, it claims, the repeated use of sonar in certain critical habitats is unwarranted. In 2010, the fisheries service approved the Navy's five-year plan for operations in the Northwest Training Range Complex, an area roughly the size of California that stretches from Washington state to Northern California. Under the five-year plan, the service said it was acceptable for the Navy to incur up to 650,000 cases of harassment of marine mammals.
Note: Sonar can drive drive marine mammals insane with the intensity of noise. Imagine a huge siren right next to your ears. You would certainly flee to try to get away. This is likely what is causing many of the whale and dolphin strandings. How much sound does it take to perforate an ear drum, as is mentioned in this article?

During a normal summer, Glacier Bay and the surrounding area buzzes with traffic, as vessels of all sizes, from massive, 150,000-tonne cruise liners to smaller whale-watching boats, ply the waters as part of Southern Alaska's massive tourism industry. The Covid-19 pandemic brought all of that to a sudden halt. Overall marine traffic in Glacier Bay declined roughly 40%. According to research by [Christine] Gabriele and Cornell University researcher Michelle Fournet, the level of manmade sound in Glacier Bay last year dropped sharply from 2018 levels, particularly at the lower frequencies generated by the massive cruise ship engines. Peak sound levels were down nearly half. All this afforded researchers an unprecedented opportunity to study whale behaviour in the kind of quiet environment that hasn't existed in the area for more than century. Gabriele has already noted changes. She compared whale activity in pre-pandemic times to human behaviour in a crowded bar. They talk louder, they stay closer together, and they keep the conversation simple. Now, the humpbacks seem to be spreading out across larger swathes of the bay. Whales can hear each other over about 2.3km (1.4 miles), compared with pre-pandemic distances closer to 200m (650ft). That has allowed mothers to leave their calves to play while they swim out to feed. Some have been observed taking naps. And whale songs - the ghostly whoops and pops by which the creatures communicate - have become more varied.

In the depths of the ocean, and out of sight for most of us, there's a quiet miracle happening. Many humpback whale populations, previously devastated by commercial whaling, are making a comeback. A recent study on humpbacks that breed off the coast of Brazil and call Antarctic waters home during the summer has shown that these whales can now be found in the sort of numbers seen before the days of whaling. Records suggest that in the 1830s there were around 27,000 whales but, after heavy hunting, by the mid-1950s only 450 remained. It is reassuring to see what happens when we leave nature to follow its course. The ban of commercial whaling in 1986 led to a strong recovery and now this population is thought to be around 93% of its original size. By taking away the threat of hunting, and having safe spaces to survive and thrive, humpback numbers in many areas have recovered. This is great news for the whales, of course, but also for the climate. Keeping carbon out of the atmosphere is key to tackling the climate crisis and the contribution that a single whale can make is something we need to take seriously. On average a single whale stores around 33 tonnes of CO2. If we consider only the Antarctic humpback whales that breed in Brazil, protecting this population alone has resulted in 813,780 tonnes of CO2 being stored in the deep sea. That's around twice the yearly CO2 emissions of a small country like Bermuda or Belize, according to 2018 emissions data.
A federal appeals court ruled Friday that the U.S. Navy was wrongly allowed to use sonar that could harm whales and other marine life. The Ninth U.S. Circuit Court of Appeals reversed a lower court decision upholding approval granted in 2012 for the Navy to use low-frequency sonar for training, testing and routine operations. The five-year approval covered peacetime operations in the Pacific, Atlantic, and Indian Oceans and the Mediterranean Sea. Sonar, used to detect submarines, can injure whales, seals, dolphins and walruses and disrupt their feeding and mating. The 2012 rules adopted by the National Marine Fisheries Service permitted Navy sonar use to affect about 30 whales and two dozen pinnipeds, marine mammals with front and rear flippers such as seals and sea lions, each year. The Navy was required to shut down or delay sonar use if a marine mammal was detected near the ship. Loud sonar pulses also were banned near coastlines and in certain protected waters. Environmental groups, led by the Natural Resources Defense Council, filed a lawsuit in San Francisco in 2012, arguing that the approval violated the Marine Mammal Protection Act. The appellate court ruled 3-0 that the approval rules failed to meet a section of the protection act requiring peacetime oceanic programs to have "the least practicable adverse impact on marine mammals." The panel concluded that the fisheries service "did not give adequate protection to ... the world's oceans."

Conservationists counted 615 dead dolphins along a 90-mile stretch of beaches in Peru ... and the leading suspect is acoustic testing offshore by oil companies. "If you can count 615 dead dolphins, you can be sure there are a great many more out at sea and the total will reach into the thousands,” Hardy Jones, head of the conservation group BlueVoice.org, said in a statement after he and an expert with ORCA Peru walked the beaches. BlueVoice.org stated that "initial tests ... show evidence of acoustical impact from sonic blasts used in exploration for oil." The ORCA Peru expert, veterinarian Carlos Yaipen Llanos, said that while "we have no definitive evidence," he suspects acoustic testing created ... a sonic blast that led to internal bleeding, loss of equilibrium and disorientation. Another possibility is that the dolphins suffered from a disease outbreak, Yaipen Llanos said. "It is a horrifying thought that these dolphins would die in agony over a prolonged period if they were impacted by sonic blast," said Jones. Numerous dolphins first started washing ashore in January, with the largest amount coming in early February. Thousands of dead anchovies were also seen. BlueVoice.org noted that the U.S. has suspended similar testing in the Gulf of Mexico due to recent sightings of dead and sick dolphins. The ban was set to last through the dolphins' calving season, which ends in May.
Note: A San Francisco Chronicle article on this a few days later states, "All of the 20 or so animals ... examined showed middle-ear hemorrhage and fracture of the ear's periotic bone. ... Most of the dolphins apparently were alive when they beached." Clearly sonic blasts of some sort are driving these intelligent animals to beach themselves and commit suicide.

Scientists have now documented behaviors like tool use and cooperative hunting strategies among whales. Orcas, or killer whales, have been found to mourn their own dead. Just three years ago, researchers at Mount Sinai School of Medicine in New York discovered, in the brains of a number of whale species, highly specialized neurons that are linked to, among other things, the use of language and were once thought to be the exclusive property of humans and a few other primates. Indeed, marine biologists are now revealing not only the dizzying variety of vocalizations among a number of whale species but also complex societal structures and cultures. Whales, we now know, teach and learn. They scheme. They cooperate, and they grieve. They recognize themselves and their friends. They know and fight back against their enemies. And perhaps most stunningly, given all of our transgressions against them, they may even, in certain circumstances, have learned to trust us. For all of their inherent elusiveness, the gray whales of Baja baffle scientists for the opposite reason: They can’t seem to get enough of us humans. The question of why present-day gray-whale mothers, some of whom still bear harpoon scars, would take to seeking us out and gently shepherding their young into our arms is a mystery that now captivates whale researchers and watchers alike. There may be something far more compelling going on in the lagoons of Baja each winter and spring. Something, let’s say, along the lines of that time-worn plot conceit behind many a film, in which the peaceable greetings of alien visitors are tragically rebuffed by human fear and ignorance. Except that in this particular rendition, the aliens keep coming back, trying, perhaps, to give us another chance.

The US navy set off a massive explosion last week, detonating a 40,000lb blast as part of a test to determine whether its newest aircraft carrier, the USS Gerald Ford, is ready for war. The test, known as a full ship shock trial, is just the first of three planned blasts over the coming months. But the amount of explosive used – 40,000 lbs – is enough to have outsized effects on any marine life in the area, said Michael Jasny, who directs the Natural Resources Defense Council's Marine Mammal Protection Project. "The navy's own modeling indicates that some smaller species of marine mammals would be expected to die within 1-2km of the blast, and that some marine mammal species would suffer injury including hearing loss out to 10km of the blast. That gives some sense of the power of the explosives we are talking about," Jasny said. "We don't know how conscientiously the blast site was chosen, and we don't know how effective the monitoring was before the detonation, so it's hard to put a great deal of faith in the safety of marine life." The area is home to populations of dolphin and small whales at this time of year, and Jasny says that's worrisome because as a general rule, smaller animals are more vulnerable to blast injury. "A large whale might need to be within a few hundred meters of the blast to die, while a small mammal could be a couple of kilometers away," he said, adding that even if the animals survive, loss of hearing is a significant problem for mammals who make their living in the ocean.
Scientists say they have seen a remarkable collection of blue whales in the coastal waters around the UK sub-Antarctic island of South Georgia. Their 23-day survey counted 55 animals - a total that is unprecedented in the decades since commercial whaling ended. To witness 55 of them now return to what was once a pre-eminent feeding ground for the population has been described as "truly, truly amazing" by cetacean specialist Dr Trevor Branch. "To think that in a period of 40 or 50 years, I only had records for two sightings of blue whales around South Georgia. So to go from basically nothing to 55 in one year is astonishing," he told BBC News. Blue whales are the most massive creatures ever to roam the Earth, and the Antarctic sub-species contained the very biggest of the big at over 30m. This population was also the most numerous of the 10 or so discrete populations across the globe, carrying perhaps 239,000 individuals prior to the onset of industrial exploitation. But the marine mammals' physical size made them a profitable catch, and around South Georgia more than 33,000 Antarctic blues were documented to have been caught and butchered, most of them between 1904 and 1925. By the time a ban was introduced in 1966, a sighting anywhere in Southern Ocean waters would have been extremely rare indeed. The last official estimate of abundance was made in 1997 and suggested Antarctic blues could have recovered to about 2,280 individuals.

[Humpbacks whales] deliberately interfere with attacking killer whales to help others in distress. They don’t just defend their own babies or close relatives. They intervene on behalf of other species - a gray whale calf with its mother, a seal hauled out on an ice floe, even an ocean sunfish. Humpbacks act to improve the welfare of others; the classic definition of altruism. Robert Pitman, a marine ecologist ... describes a pivotal encounter he witnessed in Antarctica in 2009. A group of killer whales washed a Weddell seal they were attacking off an ice floe. A pair of humpbacks ... inserted themselves into the action. One of the huge humpbacks rolled over on its back and the 180-kilogram seal was swept up onto its chest between the whale’s massive flippers. And when the seal started slipping off, the humpback, according to Pitman, “gave the seal a gentle nudge with its flipper, back to the middle of its chest. Moments later, the seal scrambled off and swam to the safety of a nearby ice floe.” Pitman started asking people to send him similar accounts. Soon he was poring through observations of 115 encounters between humpbacks and killer whales, recorded over 62 years. So are humpbacks compassionate? When I pose the ... question to Pitman he [responds], “When a human protects an imperiled individual of another species, we call it compassion. If a humpback whale does so, we call it instinct. But sometimes the distinction isn’t all that clear.”

One of the stories that inspired bestselling author Susan Casey’s new book on the intricate world of dolphins, Voices in the Ocean, is almost too beautiful to be believed. A biologist named Maddalena Bearzi was studying a group of dolphins off the coast of Los Angeles when she noticed something strange. The “pod” (group of dolphins) had just landed upon a herd of sardines. They were about to start feeding when one, unexpectedly, darted off. The rest followed, swimming full speed out to sea. When she reached them, three miles offshore, the pod had a formed a circle - in the middle of it, a girl’s floating body. Very near death, the girl had a plastic bag with her identification and a suicide note wrapped around her neck. With the dolphins' help, she was saved. The first dolphins lived on land. It took them 25 million years to adapt to being in the water. Their bodies shrank and their teeth shrank and their brains got big. They did all kinds of shape-shifting evolutionarily. Their brains grew significantly. It’s fascinating because scientists don’t know why. Most scientists’ main guess is that it was due to their changing social behavior. How did the dolphin know the girl was there? That’s the big question. They don’t rely on vision. I suspect it had something to do with frequency and vibration but of course that’s a guess. We don’t know. They tend to treat us the way they would treat other dolphins. By themselves, they’re vulnerable - to sharks, getting lost, all these things. So when you see dolphins together there is constant touching. They know how to help each other.

Environmental organizations filed a lawsuit [on December 16] against the National Marine Fisheries Service to demand it force the Navy to consider alternatives to its five-year plan that will intensify its sonar use off Southern California and Hawaii. Earthjustice, representing several groups, filed the lawsuit ... only hours after the federal agency announced it had decided to grant the Navy permits to move ahead with its plans for training and testing in the Pacific. Environmentalists [favor] creating zones that would be off-limits to biologically sensitive areas [and] want the Navy to avoid training in certain spots seasonally when they are rich in marine life. "The science is clear: sonar and live-fire training in the ocean harms marine mammals," said Marsha Green of Ocean Mammal Institute. "There are safer ways to conduct Navy exercises that include time and place restrictions to avoid areas known to be vital for marine mammals' feeding, breeding and resting." Reported mass strandings of beaked whales have increased around the world since the military started using sonar more than half a century ago. The sounds can scare animals into shallow waters where they can become disoriented and wash ashore. Aside from beachings, biologists are concerned about prolonged stress from changes in diving, feeding and communication habits. Two recent studies off the Southern California coast found certain endangered blue whales and beaked whales stopped feeding and fled from recordings of noise similar to military sonar. Beaked whales are highly sensitive to sound and account for the majority of strandings near military exercises.
Note: Consider that naval sonar doesn't "scare" marine mammals, but rather drives them insane with the intensity of noise. Imagine a huge siren right next to your ears. You would certainly flee to try to get away. This is likely what is causing many of the whale and dolphin strandings. Studies have found stranded animals to have perforated ear drums, as you can read in this NBC News article. How much sound does it take to perforate an ear drum?

In issuing a deliberately narrow ruling yesterday in a controversial case involving whales and the U.S. Navy, the Supreme Court strongly indicated that it intends to defer to the military in future disputes pitting national security against environmental concerns. The justices voted 6 to 3 to lift restrictions on the Navy's use of sonar off the Southern California coast, backing the military in a longstanding battle over whether anti-submarine training harms marine mammals. Environmentalists say the exercises disrupt habitats and leave the mammals with permanent hearing loss and decompression sickness. But the Navy argued that the training missions are essential to detecting a new generation of "quiet" submarines deployed by China, North Korea and other potential adversaries. "We do not discount the importance of plaintiffs' ecological, scientific, and recreational interests in marine mammals," Chief Justice John G. Roberts Jr. wrote in the first decision of the court's current term. "Those interests, however, are plainly outweighed by the Navy's need to conduct realistic training exercises to ensure that it is able to neutralize the threat posed by enemy submarines." Although the majority tailored its decision on narrow legal grounds and indicated that future environmental disputes will be decided on a case-by-case basis, the court made sweeping statements of deference to military judgments. Roberts unquestioningly accepted the assertion of top Navy officers that the exercises "are of utmost importance to the Navy and the Nation," writing that "the proper determination of where the public interest lies does not strike us as a close question."
A humpback whale freed by divers from a tangle of crab trap lines near the Farallon Islands nudged its rescuers and flapped around in what marine experts said was a rare and remarkable encounter. "It felt to me like it was thanking us, knowing that it was free and that we had helped it," James Moskito, one of the rescue divers, said Tuesday. "It stopped about a foot away from me, pushed me around a little bit and had some fun." Sunday's daring rescue was the first successful attempt on the West Coast to free an entangled humpback. It was a very risky maneuver...because the mere flip of a humpback's massive tail can kill a man. "I was the first diver in the water, and my heart sank when I saw all the lines wrapped around it," said [James] Moskito. "I really didn't think we were going to be able to save it." Moskito said about 20 crab-pot ropes, which are 240 feet long with weights every 60 feet, were wrapped around the animal. Rope was wrapped at least four times around the tail, the back and the left front flipper, and there was a line in the whale's mouth. Moskito and three other divers spent about an hour cutting the ropes with a special curved knife. The whale floated passively in the water the whole time, he said, giving off a strange kind of vibration. "When I was cutting the line going through the mouth, its eye was there winking at me, watching me," Moskito said. "It was an epic moment of my life." When the whale realized it was free, it began swimming around in circles, according to the rescuers. Moskito said it swam to each diver, nuzzled him and then swam to the next one.
For Alaskans, summertime means cruise ships. Lots of cruise ships. The 2020 season was expected to commence with a record-breaking deluge of 1.4 million tourists and glacier gazers that would effectively triple the state's scant population of 730,000. Once the pandemic hit, that number effectively dropped to zero. Although the economy is being decimated by the reduction in tourist vessels, the state's humpback whales are some of the few locals actually enjoying the silence. Dr Michelle Fournet, director of the Sound Science Research Collective and research fellow at Cornell University, has been listening in on whale conversations for 10 years, but never before has she seen a summer like this. "The last time researchers were able to listen to humpbacks in a quiet ocean in Alaska was in 1976," when commercial whale watching began, said Fournet, and their population was much lower as humpback whaling was banned only a decade earlier. Since that time, recording technology has come a long way and whale populations have seen a huge resurgence, with several thousand summering in south-east Alaska alone. Fournet was ecstatic after listening to her first hydrophone recordings of the year two weeks ago. "It's really, really quiet. [On] my very first pass of listening, I randomly picked a file, and I immediately heard a whale instead of a boat." The state may be facing a big economic downturn, but this is at least one fact to take comfort in, she said. "Even though we are not on the ocean right now, the whales are still there," said Fournet.
