Palau – January 2025

Palau – January 2025

Please enjoy this video about Seahawk’s visit to Palau in January 2025

Children of Palau,

I take this pledge,

As your guest,

to preserve and protect,

Your beautiful and unique

island home.

I vow to tread lightly,

act kindly and

Explore mindfully.

I shall not take

What is not given.

I shall not harm

what does not harm me.

The only footprints

I shall leave are those

That will wash away.

The Palau Pledge is a mandatory, eco-initiative stamped into the passports of all visitors upon arrival, requiring a signed vow to protect the island’s environment and culture.These words encapsulate the beliefs and ideals guiding Palawan people.The Palawan people are deeply connected to nature, practicing animism and subsistence farming. Their culture emphasizes ingasig (compassion), communal living, and, for many, a nomadic lifestyle in mountainous areas.

Seahawk arrived in Palau following a two day passage as the next destination following

her extensive cruise of Raja Ampat. The deep connection with nature and compassion

was immediately felt and experienced upon the first contact with the people of Palau

and in the cleanliness of their waters. The people of Palau care deeply for their

environment.

Recreational diving included reefs, caves and wrecks abound. Malakal and the spectacular Rock islands further south was the base for Seahawk from where dive missions were launched to the Ulong channel, German channel and to the outside of the barrier reef. The dive sites we explored on the outside of the lagoon included the German channel (Manta cleaning station), Big drop oQ, New drop oQ, Blue hole and Blue corner. Spectacular scenery and plentiful life would be an understatement, but dying coral was evident.

The Rock Islands of Palau were formed by a combination of geological processes, including volcanic uplift, coral reef growth, and erosion. Volcanic activity created an underwater mountain range, which was then covered by coral reefs over time. As sea levels changed, the coral-covered mountain range was uplifted, exposing it to the surface and forming the iconic rock islands. Further shaping of the islands occurred through erosion by wind, waves, and biological activity, resulting in the distinctive features like mushroom shapes and undercut bases. 

 

The channel was created in the early 20th century by German colonial administrators to facilitate phosphate mining and transportation. It was built using blasting and dredging methods. Today it is the primary access to the dive sites that bring in plenty of eco-tourism visitors.

Seahawk engaged with the local Palau International Coral Reef Centre (PICRC), to learn more about the land, its people and current science projects. PICRC’s vision – “Empowered Ocean Stewardship that Sustains People and Inspires the World” was very clear and immediately apparent, these guys are serious about taking care of their environment and help to make it more sustainable in a changing world.  We learned about the amazing work they are doing, identifying temperature resistant coral species, growing these species and planting them out on their reefs, to assist in making their environment more robust to the coming changes was one of many projects they are busy with.  Please look them up and assist if you can at https://picrc.org/

Seahawk hosted a lunch onboard together with a team from PICRC and Dr. Yimnang Golbuu, currently the Conservation Director for The Nature Conservancy, Micronesia and Polynesia.  It was very informative and it is great to see the collaboration between the two groups today working towards a more sustainable future and assisting their environment to be more resilient to the future.

Great Barrier Reef 2024/2025

Great Barrier Reef 2024/2025

Please enjoy this video about Seahawk’s cruise around the Great Barrier Reef between October 2024 and January 2025. 

There are few places on Earth that feel truly otherworldly. The Great Barrier Reef is one of them.

Stretching more than 2,300 kilometres along Queensland’s coastline, it is the largest coral reef system on the planet, a vast mosaic of over 3,000 reefs and hundreds of islands scattered across brilliant turquoise water. From above, it looks almost abstract. Beneath the surface, it is alive with colour, movement and intricate life.

Seagrass meadows, mangrove forests, sponge gardens and coral lagoons all weave together to form one of the most complex ecosystems on Earth. Coral reefs themselves make up only a small percentage of the Marine Park, yet they are its vibrant heart, home to thousands of species that depend on each other for survival.

Established in 1975, the Marine Park now covers 344,400 square kilometres. It is carefully zoned and managed, balancing tourism, research and conservation. Rangers monitor reef health, protect cultural heritage sites and work to prevent illegal activity. But protection alone is not enough.

The Reef is under pressure.

Rising ocean temperatures cause coral bleaching, a stress response that turns corals white and, if prolonged, can lead to their death. Recovery, once measured over decades, is now interrupted by the next heatwave before it can fully take hold. Agricultural runoff, coastal development, overfishing and powerful cyclones all add to the strain.

BRUV

One of the Reef’s most formidable natural threats is the crown-of-thorns starfish, capable of consuming vast areas of coral during population outbreaks. Targeted control programs now protect hundreds of reefs each year, giving damaged areas a chance to recover.

Each spring, after a full moon and on carefully timed nights, millions of coral polyps release tiny egg and sperm bundles into the sea. The water fills with drifting life. Most will not survive, eaten by fish or carried away by currents, but those that do – settle onto the ocean floor and begin building the next generation of reef.

It is fragile, it is extraordinary, and its future depends not only on local protection, but on global action to address the climate forces reshaping it.

The Great Barrier Reef is not just a natural wonder; it is a living reminder of both the beauty of our planet and the responsibility we carry to protect it.

Reflections on Operation Swimway: Tahanea 2025

Reflections on Operation Swimway: Tahanea 2025

Please enjoy this video about Seahawk’s Operation Swimway expedition in French Polynesia in April 2025

I have adored sharks from a young age, diving with species worldwide and always feeling they are misunderstood. Sharks have populated our oceans for 450 million years, surviving five mass extinctions and becoming one of nature’s most successful predators. Yet we are losing around 100 million each year, through overfishing, finning, bycatch, and habitat destruction. Their loss destabilises ecosystems, as prey populations boom and food chains unravel, ultimately affecting fish stocks humans choose to harvest.

Operation Swimway, managed by YachtAid Global with support from yachts such as Seahawk, works to protect critical migration corridors for sharks, rays, turtles, whales, and billfish. By studying where these animals travel, the aim is to establish more marine protected areas (MPAs). Seahawk has been involved since 2022, focusing largely on French Polynesia.

Research is complex, combining transmitter tags, passive receivers, and baited remote underwater video devices (BRUVs). These methods reduce human interference while capturing valuable behavioural and migration data. For this mission, BRUVs were deployed as deep as 70 metres using closed-circuit rebreathers. Tahanea Atoll was chosen for its three distinct passes, thought to offer unique habitats. Our primary focus was the Tiger Shark, classified as ‘Near Threatened’ on the IUCN Red List.

The 2025 expedition carried great anticipation, it was the first chance to see results from three years of work. Seahawk’s crew supported four IREMP scientists led by Dr. Clementine Seguine, diving up to four times daily despite bad weather, illness, technical setbacks, and even sharks destroying equipment.

Early in the week, the Tiger Shark we tagged in 2022 reappeared, recorded 191 times passing through Tahanea. This confirmed the atoll’s importance and lifted morale. Each evening the scientists shared updates, reinforcing the sense of shared purpose across Seahawk.

On the final day, after an exhausting push to complete the study, the biggest breakthrough came: BRUVs recorded seven threatened shark species, including two three-month-old male Tiger Shark pups. Whether they were the offspring of our 2022 tagged Tiger Shark, we cannot be sure, but the discovery confirmed Tahanea as a pupping ground, an emotional moment for us all.

Back on the dock in Tahiti, I reflected on Tahanea’s raw beauty: pristine reefs, manta rays, hammerheads, and endless schools of fish. It feels untouched, alive, and strangely, happy.

In the months ahead, we hope the data will strengthen the case to protect Tahanea and other atolls. As Adam Alpert once said, we are “custodians of the planet”. Never have I felt that more strongly than during this mission.

Bad Romance – Shark Canyon

Bad Romance – Shark Canyon

The south pass of Fakarava Island atoll, Passe Tumakohua, provides for one of the best examples of natural marine habitat facilitated by the exchange of seawater with slightly fresher water from inside a lagoon. It is the freshwater runoff (rain) that carves a path through the coral. (Corals cannot tolerate fresh water.) But beyond the formation curiosity, these passes are where the action is. The tidal currents that form both in and out of the lagoon attract a wide variety of species. Some come to these places to breed. Others, prototypically a variety of shark species, enjoy feeding and the luxury of resting on the bottom while the current effortlessly pumps oxygen through their gills.

While there are many fish species to behold, this place hosts an amazing density of gray reef sharks. Further, these animals are largely oblivious to the presence of divers. So, an up-close view is possible most days. Important to note, the danger from the gray reef sharks and most shark animals is minimal. To the extent there are attacks on humans the incidents are rare, usually caused by the shark confusing a human swimmer/surfer with normal prey during feeding times. Certain sounds including those similar to crushing an empty plastic water bottle can trigger aggressive behavior, too. Still, more people die from eating hots dogs than shark attacks.
