THE HIGH SEAS TREATY – PROTECTING THE WORLD’S OCEANS

0

LANDMARK AGREEMENT

The world has finally reached a historic agreement, aiming to place 30 percent of the seas into protected areas by 2030, to give the marine environment a chance to recuperate, build resilience to climate change and protect the lives and livelihoods of billions of people.

ESTABLISHING THE LIMITS

The High Seas Treaty was formulated on 4 March 2023, after 38 hours of talks, at the UN headquarters in New York. The negotiations had been held up for years over disagreements on funding and fishing rights. This agreement would establish limits on how much fishing can take place, the routes of shipping lanes and exploration activities like deep sea mining – when minerals are taken from a sea bed 200m or more below the surface.

LAW OF THE SEA

The last international agreement on ocean protection was signed 40 years ago in 1982 – the UN Convention on the Law of the Sea. That agreement established an area called the high seas – international waters where all countries have a right to fish, ship and do research – but only 1.2 percent of these waters were protected. Marine life living outside these protected areas has been at risk from climate change, overfishing and shipping traffic.

LATEST ASSESSMENT
In the latest assessment of global marine species, nearly 10 percent were found to be at risk of extinction, according to the International Union for Conservation of Nature (IUCN).

FUTURE MARINE ACTIVITIES

With the new treaty, the International Seabed Authority will ensure that any future activity in the deep seabed will be subject to strict environmental regulations and oversight to ensure that they are carried out sustainably and responsibly.

 

SHARING RESOURCES

The agreement took a long time to reach a consensus because the main issue was over the sharing of marine genetic resources. These are are biological material from plants and animals in the ocean that can have benefits for society, such as pharmaceuticals, industrial processes and food.

Richer nations currently have the resources and funding to explore the deep ocean but poorer nations wanted to ensure any benefits they find are shared equally.

Dr Robert Blasiak, ocean researcher at Stockholm University, said the challenge was that no one knows how much ocean resources are worth and therefore how they could be split.
A HISTORIC DAY FOR CONSERVATION
“This is a historic day for conservation and a sign that in a divided world, protecting nature and people can triumph over geopolitics,” Laura Meller, an oceans campaigner for Greenpeace Nordic said.

Countries will need to meet again to formally adopt the agreement and then have plenty of work to do before the treaty can be implemented.

Nowadays, freediving is becoming a popular activity. It allows us to  freely experience the world under the sea with minimal equipment, and also challenges our abilities and discipline.

Thailand is by far, one of the top freediving destinations in Southeast Asia. Not only are there plenty of sites abundant with marine life and corals, there is also no shortage of reputable schools.

 

Some tips on freediving

Popular Freediving Sites in Thailand

A freediver passes a huge table coral in Mo Ko Surin, Phang Nga Province

Mu Ko Surin, Phang Nga Province

Mu Ko Surin (Surin Archipelago) is a combination of two large islands, Ko Surin Neua (North Surin Island) and Ko Surin Tai (South Surin Island.) Both islands have multiple bays, and all of them are filled with rich, shallow-water corals, which are perfect for freediving.

Ko Tao (Tao Island), Surat Thani Province

Ko Tao (Tao Island) is an island in the middle of the Gulf of Thailand. This kingdom of corals is the center of the most vital dive site in the nation, which free divers worldwide are familiar with. Ko Tao (Tao Island) has many dive sites and is a base of many diving institutions. Many people travel here to get certified and log more dives as they enjoy the world under the sea.

 

An amazing underwater world awaits all ocean lovers at Ko Ran Pet-Ran Kai, Chumphon Province

Ko Ran Pet-Ran Kai (Ran Pet-Ran Kai Islands), Chumphon Province

Located in the north of Chumphon province, these twin islands aren’t far from the coast. It is a dive site favoured by many snorkellers, scuba and freedivers alike. The uniqueness of Ko Ran Pet-Ran Kai (Ran Pet-Ran Kai Islands) are the vast fields of sea anemones and skunk clownfish that swim near black coral, purple barrel sponges and red sea whips.

 

Freedivers utterly enjoy the vibrant corals in Ko Lipe, Satun Province

Ko Lipe (Lipe Island), Satun Province

Ko Lipe (Lipe Island) is one of the Mu Ko Adang-Rawi’s (Adang-Rawi Archipelago) Islands and part of Tarutao National Park. However, it is also the only island where fishing villages, Le-people communities, resorts, hotels, restaurants, and beach bars are situated. It has become a small island city surrounded by nature. Its white sand, pristine waters and many dive sites are always a big draw for tourists.

 

A freediver knows only calm and peace under the water in Samaesarn Bay, Chonburi Province

Samaesarn Bay, Chonburi Province

This is an archipelago with a bay that resembles the Thai alphabet “Ko Kai” (ก) in Thailand’s gulf. As it is on the edge of the Chonburi province, the bay and Samaesarn fishing village are under the protection of the Royal Thai navy, and the beginning of a journey to other dive sites across the archipelago.

 

The HTMS Chang is the largest, fully intact wreck in Thailand

HTMS Chang Wreck, Trat Province

HTMS Chang Wreck is located in Trat Province and has become a home to many sea creatures. It is the biggest wreck dive site in Thailand that is still intact. Divers can examine the hull, command bridge tower, mast and deck. Many sea creatures, especially batfish, live here.

Diving into Shades of Blue in Thailand

0

 

Thailand is a country that offers something for every visitor. For lovers of the sea, the southern and eastern regions are perfect for scuba diving, snorkelling and freediving. There are many ideal locations for these activities around the Andaman Sea, like Phuket, Krabi, Phang Nga, Trang or Satun, or in the Gulf of Thailand, like the surrounding islands of Pattaya, Trat, Chumphon and Surat Thani.

We’ve picked 10 of Thailand’s famous and beloved dive sites that you should not miss.

Best time for Diving

The best time for diving in the Andaman Sea and the eastern Gulf (Trat Province) is between October and May for, and between February and October in the southern part of the Gulf of Thailand (Ko Samui, Ko Phangan and Ko Tao)

10 Dive Sites in Thailand not to be missed

Richelieu Rock, Phang-nga

Because Kong Hin Richelieu (Richelieu Pinnacle) lies in the channel between Mu Ko Surin (Surin Archipelago) and the coast, currents carry rich nutrients that feed and nurture all the marine and coral life in the area, making this world-famous dive site one of the most abundant underwater ecosystems in the Thai seas.

Thousands of glass fish swarm a reef at Richelieu Rock.

Tachai Pinnacle, Phang-nga

Tachai Island is an isolated island far away from the other islands of Mu Ko Similan (Similan Archipelago) National Park. This island has a beautiful beach and a well-known dive site called Tachai Pinnacle. It is two massive rocks sitting next to each other in the south of Tachai Island that is also known as Twin Peaks. Currents are very strong here, allowing the beautiful kalam pangha to flourish as it traps the plankton passing through it.

King Cruiser Wreck, Phuket

This vessel ferried passengers between Phuket Island and the Phi Phi Archipelago until it crashed into Kong Hin Musangnai (Musangnok Pinnacle) in May, 1997. All 500 passengers were rescued. Today, the wreck resembles more of a coral reef than a ship. This is because it lies in the path of strong currents, full of nutrients and marine life, causing a bloom in colourful, soft corals blanketing the entire ship, and ultimately attracting schools of fish and other marine creatures who take refuge in the corals.

The wreck is now encrusted with hard and soft corals, surrounded by all kinds of reef fish.

Koh Haa, Krabi

Experience mountains, caves, and flower gardens under the sea in Mu Ko Haa (Haa Archipelago), which is part of Mu Ko Lanta National Park. Many divers travel from Ko Lanta Yai (Lanta Yai Island) or Ko Phi Phi Don (Phi Phi Don Island), or come on a liveaboard to these limestone islands in the middle of the sea. Whether you view it from the air, above the sea, or under the water, it is an incredible scene.

Divers swim past one of the many caves at Koh Haa.

Hin Muang – Hin Daeng Rock, Trang

Hin Muang and Hin Daeng (Muang Pinnacle and Daeng Pinnacle) are twin pinnacles under the sea. Hin Daeng (Daeng Pinnacle) just peeks a little out of the surface and looks like an ordinary rock in the water. But beneath the surface, this giant rock is covered in many soft, red and purple corals surrounded by many fishes, like barracuda, fusilier, long-nosed hawkfish, and gold belly damselfish. Hin Muang (Muang Pinnacle) slopes down to the bottom into the dark, making the soft red corals look purple.

Stonehenge Pinnacle, Lipe, Satun

Divers who discovered the site named it Stonehenge Pinnacle for the four granite rocks arranged in a circle, similar to the original Stonehenge in England. The rocks are covered with soft red, purple, blue, white, and yellow corals along with kalam pangha. The site is quite large and will take two dives see all of its beauty.

The four granite rocks stand tall amongst a vibrant display of hard and soft corals.

Losin Pinnacle, Pattani

Ko Losin (Losin Island) is a small island located far away from the coast and takes the longest time to get to. But divers still think it is worth the travel time to see an entire

kingdom of hard corals like mountain coral, cauliflower coral, sea whips, and sponges. In addition, there are hordes of small fishes and large sea creatures like whalesharks that often swim by.

A diver is impressed with the profuse amount of Acropora corals growing in gin-clear waters at Losin Pinnacle.

Sail Rock (Hin Bai), Ko Pha-ngan, Ko Tao, Suratthani

Hin Bai (Bai Pinnacle) is a large stone located between Ko Tao (Tao Island) and Ko Pha-ngan (Pha-ngan Island). The pinnacle slopes to a depth of 35 metres and is known for its large hordes of fish, which always amazes anyone who has seen it. You can expect to see Russell’s snapper, hardtail scad and big fish like whalesharks that commonly live around the area.

Divers get excited when they meet the largest fish in the ocean – the whaleshark– at Sail Rock.

Chumphon Pinnacle, Ko Tao, Suratthani

This site is suitable for experienced divers as the current can be very strong at times. The pinnacle is at a depth of 14 meters, but the average diving depth is 20-25 meters. Divers will find many types of hard coral, sea whips, a large anemone grove, and large schools of fish, such as barracuda and yellow-striped scad. However, the divers’ favorite is the whaleshark, a large, gentle fish that often visits the site.

This large sea anemone grove is a favourite spot for photographers who want to capture a lot of fish action at Chumphon Pinnacle.

Hin Phoeng, Rayong

Many divers agree that Hin Phoeng (Hin Phoeng Pinnacle) is the most beautiful dive site in the eastern region. This pinnacle is far from the coast, and visibility is very good.

Hin Phoeng (Hin Phoeng Pinnacle) is actually two large pinnacles. Many marine creatures can be found here and you will often find yellow-striped scad, batfish, lionfish, bannerfish and whalesharks.

The great visibility at Hin Phoeng greatly amplifies the beauty and colours of the site.

Voice Of The Ocean: Best Of Show 2022

Text by Jules Casey

Photography by Jules Casey

 


 

Jules Casey’s “The Circle of Life” won Best of Show in the ADEX 2022 Voice of the Ocean photo/video/art competition. 

The Australian photographer talks us through exactly how she captured her shot of the Pale Octopus in a PVC pipe protecting her eggs.

 


 

The COVID-19 pandemic caused chaos all over the world, but residents of the state of Victoria in Australia faced tougher restrictions than most. During six separate lockdowns totaling 262 days, I was unable to scuba dive for months, but eventually, as part of the two hours allocated for daily exercise within a five-kilometer radius of home, I was allowed to set up my camera gear and get back underwater.

Perhaps inspired by their lack of activity during lockdown, two local divers decided to build an artificial reef close to my home, and although I wasn’t involved in the construction of the reef, I documented every stage of the project as it took shape. After a few weeks, it was suggested that installing a toilet would be a great idea, as it would provide a safe place for octopuses to lay their eggs in the S-bend of the toilet bowl. Within two days of its installation, the first pale octopus

Several PVC pipes were secured around the other structures within the reef and an explosion of activity happened virtually overnight. The octopuses loved their new playground, and at times there would be a dozen or more hiding within the structures. The new reef also attracted a variety of fish and crabs to the area, and as a photographer and videographer, I was thrilled with what was happening and documented behaviors I had never captured before.

The foreplay of pale octopuses would last for hours and sometimes days. Individuals fighting and mating was a common occurrence, and this continued for months until eventually the females settled in the pipes and laid their eggs. The pale octopus attaches each egg case individually so it hangs within a structure around them, and then continually moves fresh water around her brood for several months until they are ready to hatch. During this time, she does not leave her eggs nor does she hunt for food or eat. I would visit this site almost every day that weather conditions would allow, briefly checking on several expecting mothers and their developing eggs.

My favourite octopus was in a pipe that had been positioned in an extremely tight spot that was impossible to fit my large camera rig with strobes into, so I used a compact camera and a small handheld torch to properly light the shot instead. The octopus was often in front of her eggs protecting them from predators, so it was difficult to capture the image I wanted, but one day my patience paid off and she moved behind her eggs, allowing for the perfect composition.

Sadly, it wouldn’t be long before the eggs would hatch and the caring mother would die after completing her biological life cycle, but I was thrilled to be able to capture her bittersweet story in this one shot—“The Circle of Life.”

One day, she moved into the perfect position to capture my winning shot—here in the uncropped original shot

The Origins Of “freediving”

0

With diving equipment undergoing constant innovation, allowing us to dive deeper and longer underwater, it’s easy to forget that the art of diving began as a simple act of holding one’s breath. Indeed, with the advent of modern underwater breathing apparatuses, the most primitive form of diving is now differentiated by the moniker “freediving”. But breath-hold diving began over 8,000 years ago, evolving over the centuries to its ultra-modern, present-day form. Now, freediving is constantly testing humans’ physical and mental limits, as the sport of competitive freediving continues to gain popularity.

 

ANCIENT DIVING

The first recorded evidence of freediving can be traced back more than 7,000 years to the Chinchorros, an ancient civilization that lived along the coast of the Atacama Desert (present-day northern Chile and southern Peru).

In a study of Chinchorro mummies, researchers discovered that the bones inside their ears started to grow across the ear canal’s opening, protecting the eardrums from repeated exposure to water. It was clearly a case of exostosis, a condition that afflicts. people whose heads have been frequently dunked underwater. Colloquially called “surfer’s ear”, exostosis is a common condition among people who surf, dive or kayak. Shell-ridden fossils and bone chemistry tests on the mummies have proven that their diet consisted of 90 percent seafood.

Besides the Chinchorro in South America, seashell fossils found on the coast of the Baltic Sea have also revealed that ancient people who lived about 10,000 years ago freedived for clams. There is also plenty of archaeological evidence pointing towards diving in Mesopotamia (present-day Iraq, Kuwait, and Syria), dating back to 4,500 BCE, as well as in ancient Egypt, to around 3,200 BCE.

The Greeks have been diving for over 4,000 years. Artefacts and scripts from the Minoan civilisation, which flourished from 2,700 BCE to 1,450 BCE on Crete and other Aegean islands, include figures of seashells as well as colors produced by seashells in Minoan ceramic art.

SRI LANKA (CEYLON)For thousands of years, the Gulf of Mannar, which lies between southern India and western Sri Lanka, was known for the pearls and chanks (large spiral shells) harvested from the waters of Mannar Island by local divers. According to the Mahavamsa, the historical chronicle of Sri Lanka, Prince Vijaya landed in Sri Lanka in 543 BCE and sent a gift of a shell pearl worth twice 100,000 pieces to a Pandu King upon taking the hand of his daughter. The ancient Greeks, specifically Megasthenes, the Greek ambassador to the Mauryan royal court in India, also wrote in the 3rd century BCE about the brilliance of the pearls from Mannar Iceland. In ancient Greece, Sri Lanka was known as “Palaesimoundu”.

Literature from the Sangam Period (3rd century BCE to 3rd century CE) such as the Agananuru, an anthology collection of classical Tamil poetic work dated around the 1st and 2nd century BCE, touched upon a community named Parathavar that fished but also dived for pearls and chanks. Arab traders and divers from the Persian Gulf also ventured into the pearl fishery trade in Sri Lanka between the 7th and the 13th century CE.

Research detailed that the early divers of Sri Lanka would go out to sea in crews as large as 23 in a boat. On each boat would be a tindal, or a steersman; a saman oattee, who was in charge of the boat; a thody, who was tasked with bailing water out in addition to cleaning the boat; 10 miscellaneous including the adappanar, or lead diver; and 10 munduck, or operational assistants. They would pull up the oysters, the stone counterweights and the divers themselves from the seabed and back onto the boat.

The boats would be set out late at night, around midnight. The tindals would have begun preparing to hoist the sails more than an hour or so before, with the adappanar hoisting a light at the masthead as a signal to set off. The divers on the boat would then get ready in the early hours of the morning by attaching the safety ropes around their waist. Stones would be tied to the ropes to act as counterweights for the divers to make a fast descent to the seabed. As the ropes with the weights were released into the water, the diver would take a deep breath and rapidly descend by stepping onto these weights. The moment they reached the seabed, they would start collecting oysters into the nets around their waist, while the weights were simultaneously pulled up to the boat. After about a minute, the diver would tug the rope that was tied to him to signal the completion of his task, upon which he would be pulled up along with his collected oysters.

 

AMA: JAPAN

The ama are coastal people residing in Japan who make their living by diving to harvest abalones, turban snails, oysters, and pearls. Japanese literature suggests that the ama have existed for at least 2,000 years. One of the oldest references to the ama divers is the Gishi-Wajin-Den (M), which is believed to have been published in 285 CE. Some of the oldest archaeological evidence from Japan holds that the Japanese have always depended on seabed resources for sustenance.

According to an ancient Chinese chronicle containing sporadic references to Japan, the northwestern part of what is now Kyushu lacks arable land that enables its people to survive on agriculture, compelling them to depend on the sea to barter for staples such as rice. According to Minoru Nukada from the Department of Health and Physical Education at Toho University, male and female ama engage in different diving activities.

Originally, male ama tended to catch fish, either by hand or with a spear, whereas female ama would dive to the seabed to collect seaweed and shellfish. Over time, the men engaged in offshore fishing or became sailors on ships while the female ama stayed at home and dived to supplement the farming harvest. They are also believed to be more adept at holding their breath. The ama are trained as early as 12 or 13 years by the elders. At this stage of their training, they are known as Koisoso or Cachido and dive at shallow depths of only two to four metres.

Traditionally, the female ama dives into a fundoshi (loincloth) for ease of movement with only a tenugui (bandana) covering their hair. These headscarves are sometimes adorned with symbols in order to bring luck to the diver and ward off evil. They use a safety rope attached to a wooden tub or barrel that serves as a buoy to rest on between dives. The barrel is also used to store their catch. Their most important tool, however, is the tegane or kaigane – a spatula-like tool used to pry out abalone between the rocks on the seabed. The Meiji era (1868 1912 CE) introduced goggles, which were adopted by the ama. In the decades following World War II, some ama started wearing a white sheer garb for modesty while others started wearing black rubber wetsuits in the 1960s.

HAENYEO: KOREA

Like the ama of Japan, the haenyeo of Korea are women freedivers who make a living from diving and harvesting shellfish and seaweed from the seabed. The haenyeo are found in the southern part of the Korean Peninsula, particularly Jeju Island. Although the exact conception of freediving in Korea is unclear, Korean history experts collectively agree that Jeju was the place where the haenyeo were first found. Archival records reveal that as early as 434 CE, pearls were found in the Silla Kingdom. Again, it is not known how freediving for seafood came to be a female-only activity. One likely explanation is the physiological advantage that women have. This is greater subcutaneous fat and a perceived ability to withstand the cold better than men. Like their Japanese counterparts, the haenyeo start learning to freedive in shallow waters at 11 or 12 years old and as their skill level progresses, they graduate to an advanced level when they turn 17 or 18.

Jeju ‘haenyeo’ divers sing their traditional work song “Ieodo Sana” before they set out to dive near Seongsan Ilchulbong.

The haenyeo divers wear black swimming trunks and white cotton jackets. Diving goggles were introduced during the 1930s, with eye glasses used for almost two decades before diving face masks became available. They traditionally use hollowed-out gourds about 30 centimeters wide as floats.

SAMA-BAJAU: SOUTHEAST ASIA

All freedivers are familiar with the “mammalian dive reflex”, when your heart slows down, blood vessels constrict and your spleen contracts because your body is trying to keep you alive while you are holding your breath underwater.

The Sama-Bajau are a group of sea nomads consisting of several Austronesian ethnic groups who live off the sea in waters enveloping the Philippines, Malaysia, Indonesia and Borneo.

A study on human hypoxia tolerance published by the journal Cell revealed that a genetic mutation has allowed the Sama-Bajau to develop larger spleens, which makes more oxygen available in their blood while diving. With this oxygen boost, the Sama Bajau can freedive to greater depths of up to 70 metres, for as long as 13 minutes. In the human body, the spleen recycles red blood cells and supports the immune system. After previous studies revealed that diving mammals like elephant seals, otters and whales have disproportionately larger spleens, Melissa Llardo, the author of the hypoxia study in Cell was eager to find out if the same was true in humans. Her studies revealed that the median size of the spleen of a Sama-Bajau was 50 percent larger than that of the Saluan people, a related group on the Indonesian mainland. The Sama Bajau were also found to have a gene called PDE10A (which the Saluan did not have) that is thought to control a certain thyroid hormone that in mice is known to be linked to spleen size.
