"230 Decibels" - 🔵@maestro320 s Notes: 🔊🔊🔊 This incredible footage of a nursing calf and mother Sperm Whale was filmed on location off the Coast of Dominica courtesy of Freediver, Ulysse Nardin @ulyssenardinofficial , Mares @maresjustaddwater and Seacam Ambassador, Underwater Photographer and Filmmaker, Fred Buyle @fredbuyle - When a baby sperm whale and his mum says hello to you...! How can nations still discuss the possibility of resuming whale hunting? - In this post, I'd like to take particular to the sounds or vocalizations of Sperm Whales. They are capable of emitting sounds at a volume of 230 decibels—more than an airplane jet engine at takeoff—the sperm whale is the loudest animal in the world. When echolocating, the sperm whale emits a directionally focused beam of broadband clicks. Clicks are generated by forcing air through a pair of phonic lips (also known as "monkey lips" or "museau de singe"). The creak is a rapid series of high-frequency clicks that sounds somewhat like a creaky door hinge. It is typically used when homing in on prey. A coda is a short pattern of 3 to 20 clicks that is used in social situations. They were once thought to be a way by which individuals identified themselves, but individuals have been observed producing multiple codas, and the same codas are used by multiple individuals. However, each click contains a physical signature which suggests that clicks can be used to identify individuals. Geographically separate pods exhibit distinct dialects. Large males are generally solitary and rarely produce codas. In breeding grounds, codas are almost entirely produced by adult females. Despite evidence that sperm whales share similar codas, it is still unknown whether sperm whales possess individually specific coda repertoires or whether individuals make codas at different rates. Slow clicks are heard only in the presence of males (it is not certain whether females occasionally make them). Males make a lot of slow clicks in breeding grounds (74% of the time), both near the surface and at depth, which suggests they are primarily mating signals. Outside breeding grounds, slow clicks are rarely heard, and usually near the surface https://www.instagram.com/p/B_XH6I2gSEA/?igshid=iq3glcidd525

Ulysse Nardin has just offered a grant to the Azores University’s marine research centre to acquire ten pop-up biologging sensors to tag blue sharks in the Atlantic and document our knowledge of this endangered species. Swimming with blue sharks, his DIVER 44mm on the wrist, Fred Buyle tags marine animals in their natural environment using non-invasive techniques. Buyle is using his underwater photography and freediving skills to change the way we see the seas.

Many marine species are difficult to study because components of their lifecycles occur solely or partially outside of the observable realm of researchers. Advances in biologging tags have begun to give us glimpses into these unobservable states. However, many of these tags require rigid attachment to animals, which normally requires catching and restraining the animals. These methods become prohibitive with large, dangerous, or rare species, such as large predatory sharks, and can have significant consequences for individual survival and behaviour. Therefore, there is a need for methods and hardware to non-invasively and rigidly attach biologging tags to sharks that present limited effects on the animals and researchers.

Blue sharks tagging

Scientists in the Azores islands of Portugal are gaining a new understanding into the lives of one of the ocean’s most fascinating and mysterious creatures, the blue shark (Prionace glauca). Jorge Fontes, an Azorean native marine ecologist at Okeanos-UAc marine research center, University of the Azores, leads a team of researchers studying this charismatic elasmobranch in the Azores archipelago. Though recreational divers come from all over the world to see the memorizing sharks, not much is known about the natural history fine-scale behaviour and habitat use. With the help of Fred Buyle, combining their amazing freediving skills with creative non-invasive attachment methods and state-of-the-art prototype data and video logging towed tags, Jorge Fontes has been pioneering the investigation of their fine-scale behaviour and ecology, providing a new and unprecedented look into the life of these mysterious and elegant sharks.

The beauty of the new non-invasive tagging method lays on its simplicity. Like an underwater cowboy, the free divers place a self-releasing “lasso” that is retained on the shark’s pectoral fins as they constantly move forward to force the water flow through the gills, towing the low drag torpedo-shaped camera tags and sensors. These innovative tags, rated to 2000 meters, combine multiple high-frequency accelerometers, magnetometer, speed, depth, temperature sensors as well as HD video. At night and bellow 100 m, two red LEDs are triggered to allow a glimpse into the world of darkness that contrasts with the crystal-clear water at the top of the seamounts. Red lighting is designed to not impact the behaviour of both the sharks and their prey. After 24 or 48h, the lasso dissolves and the tag floats to the surface and to transmit satellite and radio beacons used to track and recover the tags for data download and recharge for the next deployment. Using these tools, the team will be able to learn some of their secrets.

Bold, respectful and talented, Fred Buyle has not finished surprising us.

Three sharks are killed by man every second as against five humans killed by sharks each year [1].

90 % of sharks have disappeared from the Mediterranean [2].

By targeting sick or wounded fish, sharks keep the ecosystem in balance [3].

Tens of tagged great white sharks led scientists to a remote mid-Pacific area where they gather for a few months. It was nicknamed the “White Shark Café” [4]!

The thresher shark uses its surprisingly long caudal fin to whip and knock out its prey [5].

Questions & Answers With Fred Buyle & Jorge Fontes

How long does the tag remain on the shark?  

It normally remains up to 48h but it can also be more.

What is the list of the parameters detected with the tags?

We record high frequency (100 Hz; 100 measurements per second), 3D acceleration, gyro and magnetic heading, speed, depth and temperature. Moreover, when the shark surfaces for less than a second, its GPS position is recorded. We also collect the HD video with red lights in the camera tag version. We are interested in the vertical and horizontal behaviours, feeding and social interactions and energy use, based on the tail beats and speed essentially.

Are there any advances in miniaturization of these biologging tags? They seem very big for the animal. 

We are currently looking for funding to miniaturize the tags. Anyway, the tags are super low drag, which signifies that we don’t add more than 5% drag and float to the animal, meaning we are limited to tagging blue sharks over 2.5 m long.

Is there a massive potential of animal-borne sensors to teach us about the oceans and global warming?

Yes. We are currently looking to integrate an O2 sensor in our tags to learn how the deoxygenation of the oceans due to warming, and excess of CO2 will affect deep diving sharks that forage at depth for example. Devil rays and whale sharks also dive very deep, possibly to forage or to orient themselves over long migrations. Therefore, if O2 is depleted at depth, it will be a barrier for these guys.

Sometimes an animal’s mood makes all the difference. Are they surprisingly easy to tag – if you can catch them at the right time?

Indeed, we can only tag the animals that are “in the mood”. If we try to impose our methods, the animal will just swim away, therefore yes, we depend on the animal’s attitude and character.

What is the average time that it takes to see a blue shark and put a tag on it? Is it 10 minutes, an hour? 

It is hard to say, because chumming to attract can range from 10 min to 4-5 hours. It is very variable and depends a lot on the behavior and abundance of sharks in the area.

Apparently, researchers have developed a huge variety of workarounds and electronic tags. Can you tell us more about what’s available for scientists today?

Today the most popular technology used are the acoustic tags (they output a “ping” that needs to be tracked with a hydrophone – active following or a network of stations) and satellite tracking tags. The most used sat tags are spots (ping position when at the surface for a few minutes) and PAT archival tags, that measure and archive (over months) depth, temperature and light levels. In the end, the stored information is sent to a satellite and to the researcher. Light levels can be used to estimate movement tracks over large scales (ocean wide), but the error is significant at smaller scales. There is a number of custom-made tags that have similar sensors as we have but are all for fixed attachment, and you normally need to fish and restrain the shark. If it’s a big shark and you can approach, they can be attached to the dorsal fin with a clamp.

Can you show us a chart or any results of a successful tag monitoring? 

This is relatively complex as there are many variables being measured. Below is an example regarding the depth and tail beet cycles of a tiger shark we did recently in Hawaii.

About Fred Buyle

Buyle is a free diver and underwater photographer born in 1972. He has been connected to the sea since childhood when he spent several months each year on the family sailboat. At 10, an age when most kids are still skipping rope in the schoolyard, he discovered free diving. Plunging into the oxygen tank-free technique for the next years of his life, he became a scuba diving instructor, teaching free diving in beginning in 1991.

He set his first world record in 1995 and decided to dedicate his life to free diving. He broke three additional world records between 1997 and 2000 and in 1999, passed the mythical 100-meter depth on one breath of air.

In 2002, he began a second career in underwater photography. His goal:  to show the beauty of free diving and the animals in their natural, underwater world. Using only natural light, Buyle has captured images of sharks, ray, fish, dolphins and countless other majestic specimens of marine life.

Buyle comes from an artistic background; His grand grandfather was a pioneer of photography in the 1890’s, his grandfather was a painter and his father an advertising and fashion photographer during the 1960’s. His work reflects these influences, showing a subtle beauty that only comes with an experienced eye.

Buyle uses a simple formula for his photographs: water, available light, a camera and one breath of air. With simple equipment and freedom to move around, a free diver can capture unique moments. Fred has been taking pictures as far down as 60 meters on a single breath of air in remote locations inaccessible to even scuba divers. This “Zen” approach makes Buyle’s photography different from any other underwater photography.

Concerned by conservations issues, in 2005 Buyle began to work with marine biologists, assisting them in their field work. He uses his freediving abilities to approach the animals and perform tasks such as acoustic and satellite tagging and DNA sampling. Buyle has worked with teams from Colombia, Mexico, France, the UK, the Philippines and South Africa, sharing his practical knowledge and personal experience with marine life. Fearlessly approaching great white sharks, great hammerheads, scalloped hammerheads, lemon sharks, ferox sharks, humpback whales, sperm whales and orcas, he never uses a protective cage, which can disturb the animals.

During these missions, Fred carefully documents the field work he performs in order to contribute to the conservation efforts on a larger scale through talks, conferences and his own website. He believes that positive imagery is more effective than the catastrophism widely used in the media nowadays and his images are used by NGOs around the world for their conservation campaigns.

This is the story of Ella Addison, an extraordinary 12 year old girl who swims with sharks. It is a family tradition. When she enters the underwater world of Shark Rock she comes face to face with Tiger Sharks , Blacktips, Bull sharks and Raggies. Curious by nature and with the help of her grandfather, her parents and a Marine biologist, Ella starts a school project aimed at solving this mystery. The Addison’s is not your normal average family. Grandfather Brent Addison, an oceanographer designed and built the first underwater habitat in the seventies. Ella’s love for the ocean runs deep. Her parents, Mark and Gail Addison run Blue Water Wilderness, a diving company that offers film logistics and face to face encounters with sharks. Shark Rock on the South Coast of Kwa-Zulu Natal is practically in their back yard and Tiger sharks, their biggest attraction. They are particularly busy during the annual Sardine Run when different species of sharks attack massive moving bait-balls. Black Tips migrate to Shark Rock to partake in this feast and then move on. But for the past three to four years, they are staying put. Mark begins to notice the effect on the resident population. His Tigers are disappearing. Ella however, has fallen in love with the Black Tips. She calls them her 12 dancing princesses. Where do they come from? Why are they only females? Where are the males? These happen to be the same questions that intrigue Jessica Escobar, a feisty Colombian Marine Biologist doing her doctoral thesis on Black Tips. She has a few more riddles to solve: Are these black tips related, do they hunt collaboratively and what impact do they have on Tigers, Raggies and Duskies? Mark would also like to know as his business depends on regular interaction with Tigers. Ella and Jessica make a formidable team. They team up with champion free-diver Fred Buyle who flies in from Belgium. Diving without scuba, he gets much closer to the sharks. He collects DNA samples using a modified spear gun. While Jessica compiles and analysis the genetic information, Ella compiles a visual diary of her dives on Shark Rock to present to her school. Ella joins her Grandfather, now almost 80, in search for the wreck of the first underwater habitat. Together they dream up the idea of building another submersible housing unit to accommodate the crazy Shark Family Addison. Brent has a vast knowledge and has seen a change happening on reefs such as Shark Rock. He reckons global warming and over-fishing could have triggered the Black Tip invasion. Brent becomes another expert in Ella’s school project. But it is the research that Jessica and Ella initiate that solves the wonderful Secret of Shark Rock.

"Surveying Underwater Galaxies" - 🔵 @maestro320 Notes: Incredible footage filmed on location in West Papua courtesy of Freediver, Explorer, Naturalist, Nikon Photographer, Waterman, Ulysse Nardin @ulyssenardinofficial and Mares @maresjustaddwater Ambassador, Fred Buyle @fredbuyle - Great memories from a few years ago while filming whale sharks in Papua! The largest recorded Whale Shark, approximately 20 m TL (Chen et al. 1997) and 42 t in mass (Hsu et al. 2014), have been reported from Taiwan. An individual extrapolated to be 18.8 m TL was caught in India (Borrell et al. 2011). Norman and Stevens (2007) found that 50% of males were mature, based on clasper morphology, at a visually estimated TL of 8.1 m in Western Australia, while 50% maturity was estimated to occur at 9.2 m TL using laser photogrammetry in Mozambique (Rohner et al. 2015). In the Gulf of Mexico, Ramírez-Macías et al. (2012) visually estimated 50% male maturity to occur at around 7 m TL. Given the genetic differentiation between the Indo-Pacific and Atlantic Oceans (Vignaud et al. 2014), this may represent a subpopulation-level difference in the size of maturation. Size at maturity in female sharks is approximately 9 m TL, based on visual (Acuña-Marrero et al. 2014, Ramírez-Macías et al. 2012) and laser photogrammetric estimates (Acuña-Marrero et al. 2014) from the Eastern Pacific, and a 9.6 m TL individual recorded from Taiwan (Hsu et al. 2014). All of seven stranded female specimens from 4.8 to 8.7 m TL in South Africa were immature (Beckley et al. 1997). The only confirmed pregnant female examined, from Taiwan, was 10.6 m TL (Joung et al. 1996). Whale Shark reproductive ecology is poorly known. Pregnant female sharks are seasonally found in the Eastern Pacific, particularly off Darwin Island in the Galapagos Archipelago (Acuña-Marrero et al. 2014) and the Gulf of California (Eckert and Stewart 2001, Ramírez-Macías et al. 2012), but rarely sighted outside this region. An exception is St Helena Island in the mid-Atlantic, where pregnant female sharks are routinely observed on a seasonal basis (A. Dove, pers. comm). https://www.instagram.com/p/CAxvAGvAGbJ/?igshid=173x7fr1ogy89

Great on the wrist, even greater in the water I am a desk diver that enjoys a nice chrono and occasional snorkelling. Am I the best one to recommend a diver watch? Certainly not… But I know that the Ulysse Nardin diver watches are done under the guidance of professionals (like Fred Buyle or Mike Coots) and they spare no critics since they need to rely on the tool on the wrist. The watch is engineered for depths up to 300m and the Superluminova is carefully chosen. So I am sure most of use will be OK. The watch wears smaller than expected. I photographed the watch long before I had the tech specs and I didn’t realise that is factic so large. It wears great, it looks great and comes with good deeds. And here is something important to say. https://www.instagram.com/p/CgKt7UvLVQL/?igshid=NGJjMDIxMWI=

whale sound notes

Sperm whale vocalisations have long fascinated scientists for one reason in particular. They are almost inconceivably loud. While normal human speech takes place between 60 and 65 decibels (dB), sperm whale clicks, described as such because we hear them as "tak-tak-tak", can reach as high as 235dB. In contrast, a loud rock concert is around 115dB and the sound of a jet engine is roughly 140dB. Quite simply, sperm whales are the loudest animals on the planet.

Such is the power of their clicks that whales can comfortably transmit information to others from hundreds of miles away, and even across vast oceans. A sound of 180dB is enough to cause drastic cell death in your ears, but the most powerful sperm whale clicks will not merely deafen you: they can vibrate the fragile human body to pieces.

The whales have evolved these astonishingly powerful vocalisations to cope with their extraordinary lifestyle.

Sperm whales range across the open ocean, but they typically gather at deep canyons, to socialise, mate and hunt food sources no other predator can reach. They dive up to 10,000ft under the ocean surface, hunting for fish and giant squid.

"Sperm whales spend most of their lives in the darkness because they hunt in a part of the ocean where light does not reach," says Fred Buyle, an underwater photographer and cameraman with DareWin. "They use these clicks as a visual tool to see and analyse what's around them. They perceive the world through sound."

Sperm whales sometimes produce special clicks called "coda clicks". When slowed down and viewed on a computer, these clicks reveal almost infinitely detailed layers. Each click contains a series of smaller clicks interlaced within, and a series of even smaller clicks within those, and so on.

The time intervals within these clicks are of the order of milliseconds, yet sperm whales can replicate them exactly. They can also make precise revisions, reorganising the pattern of the clicks within a click and then sending it back to a neighbour, all within a fraction of a second.

This is a level of control that humans lack. Our voices vary constantly in volume and frequency, so that the same word spoken twice will never be exactly the same.

"Human speech is built on units of sound called phonemes," Schnöller says. "When we speak, we put it in a timescale, like 'I', 'talk', 'to', 'you.' It's analogue. Sperm whale communication is digital. They transmit a thin sound with all the information contained inside it and then they can modulate it, a bit like the way the internet works."

...

The solution is to use advanced computer algorithms to examine thousands of clicks, breaking them down and analysing their frequency structure and organisation, and probe for common trends.

Glotin, the head of an international bioacoustic research consortium called SABIOD, is combing through data collected from sperm whales around the world. He is using machine learning – the same techniques that banks use to predict stock market trends – to see whether each whale has a unique "signature" in their clicks that identifies them, in the same way that every human has a unique voice.
