Canada – Summer 2025

Please enjoy this video about Seahawk’s visit to Canada in Summer 2025.

After a year in the South Pacific, Seahawk turned north, swapping warm turquoise waters for the crisp air and long summer days of Canada’s west coast. A brief stop in Ensenada for hull repairs behind us, we crossed into British Columbia and into a dramatically different world.

Pacific white-sided dolphins surfed in our wake, humpback whales breached in the distance, and glacier runoff transformed the sea into luminous shades of turquoise. Logs drifted silently past, curious seals surfaced to inspect us, and the vast forests felt wonderfully untamed.

Ashore, we wandered through Rebecca Spit gathering wild blackberries and kayaked quiet rivers, always mindful that this is bear country. Near Knight Inlet, we observed grizzlies and cubs from a safe distance.

British Columbia’s coastal waters are also home to orcas. The small southern resident population is critically endangered, with only around 74 individuals remaining. Their primary food source, Chinook salmon, has declined significantly, placing immense pressure on their survival. Increased marine traffic and underwater noise add further strain. Without meaningful conservation efforts, their future is uncertain.

In contrast, Bigg’s orcas (also known as transient orcas) appear to be faring better. We were fortunate to encounter a pod near Thurston Bay, easily recognized by their distinctive dorsal fins and markings. It was an unexpected and uplifting moment during our journey south.

The natural beauty is stunning. But perhaps equally impressive is the demeanour of the people. Everyone we have met has been exceedingly friendly, welcoming, and kind. There is also a genuine generosity that transcends the need for conventional transactions. Mostly, though, it is the caring way members of the community treat each other that confirms a superior merit.

The Salmon Story

Salmon are woven into the fabric of this coastline. Local fishermen told us the runs have been thin this year, a reflection of broader declines affecting many species across the province. Fresh salmon was surprisingly hard to come by in British Columbia. We received a few puzzled looks when we asked locals if they had any salmon to spare from their catch. Later, we learned that trading or selling recreationally caught salmon is illegal, which quickly explained the awkward glances.

 

Wild salmon in British Columbia face mounting pressures: climate change, habitat degradation, historic overfishing, and the ongoing impact of open-net salmon farming. While recreational fishing is generally well-managed and localised, both historic commercial harvest and aquaculture practices have left lasting effects.

Open net pen farmed salmon is widely identified as a significant threat to wild salmon due to disease transmission, sea lice, pollution, genetic impacts from escapes, and other operational risks. It is frequently cited as a contributing factor in the decline of wild salmon populations in southern British Columbia. In response to these concerns, the Government of Canada has announced a plan to transition away from open net pen salmon farming in British Columbia’s coastal waters by June 30, 2029, with the stated goal of protecting wild salmon. More information on open net pen farmed salmon can be found at https://www.wildfirst.ca/issue/

Sources of Salmon:

Best Choice: Opt for wild-caught B.C. salmon certified either by Ocean Wise, the MSC, or Friend of the Sea.

 

Good Alternative: Choose land-based, closed-containment farmed salmon from suppliers like Kuterra or Sustainable Blue.

 

Avoid open-net pen–farmed salmon from B.C. due to ongoing environmental and ecological concerns.

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/

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.

Grey Reef Shark and divers

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.

A Personal Reflection

I am thrilled to be making my first contribution to the Seahawk Mission Logs, and this entry is especially close to my heart.

To introduce myself, I am Sarah, and I work as the Second Stewardess aboard Seahawk. My connection to the ocean runs deep, but it truly began in 2014 when I moved to Australia and experienced my first dive on the Great Barrier Reef, not far from Airlie Beach. It was nothing short of magical. The coral was bursting with colour, and shimmering schools of fish surrounded me. If I told you I felt like I’d been transported into King Triton’s kingdom from The Little Mermaid, it wouldn’t be far from the truth.

But the reality of our changing oceans hit me just a year later. I returned to Airlie Beach to work on a dive vessel, same place, same waters, but a very different underwater landscape. Much of the reef was bleached and broken. There were still pockets of beauty, but large sections reminded me more of the Elephant Graveyard from The Lion King than the vibrant world I had first fallen in love with. (Yes, I’m a passionate diver and Disney enthusiast.)

That moment, ten years ago to the day, was when I truly understood how fragile these underwater ecosystems are, and how quickly they can change.

Which is why I am so proud to share this next chapter: SY Seahawk’s visit to Kalig Reef Station, a project at the forefront of coral research. The work being done here is pioneering. It’s focused on understanding coral resilience in the face of rising ocean temperatures, something that feels deeply personal to me and is urgently necessary for all of us who care about the ocean’s future.

At the Heart of Coral Conservation: Kalig Reef Station

On December 7th, 2024, we arrived at Kalig Reef Station aboard SY Seahawk, deep within the Misool Marine Reserve in Raja Ampat, Indonesia. Raja Ampat is one of the most colourful and diverse underwater places on Earth, home to approximately 75% of the world’s coral species. Walking into this remote research station felt like a small piece of paradise, and we couldn’t wait to learn about the important work being done here and lend our assistance.

Kalig is run by the Misool Foundation, Indonesia’s only marine conservation group dedicated to saving these incredible reefs. The vibrant coral here supports an amazing array of marine life, from graceful manta rays and reef sharks to sparkling schools of fish that swirl like living rainbows.

The sheer biodiversity in these waters makes them a critical stronghold for global reef conservation. What is learned in Raja Ampat could inform coral protection strategies for threatened reefs all over the world.

Why Coral Matters, and Why It’s in Danger

You can identify healthy coral as it is full of tiny algae that give it energy and bright colours. When the water becomes too warm, coral becomes stressed and expels the algae, turning pale or white, a warning sign known as bleaching. If the heat keeps up, the coral can die, and with it, the entire reef ecosystem suffers.

These algae, called zooxanthellae, are not just passengers; they are essential partners in coral survival. Through photosynthesis, they provide up to 90% of the energy that corals need to grow and build reefs. When coral loses them, it’s like pulling the plug on a life-support system.

Seeing this fragile process up close was heartbreaking. Coral isn’t just a beautiful part of the ocean; it is the ocean’s foundation. Without it, countless marine creatures lose their homes and food. The work being done at Kalig Reef Station is crucial for giving coral reefs a fighting chance.

The Coral Resilience Trials: Hope in Science

Our visit centred on a groundbreaking project known as the Coral Resilience Trials. Scientists here are working to find out which types of coral can survive warmer ocean temperatures, a question that could determine the future of coral reefs worldwide.

We had the privilege of joining an inspiring team of scientists, including Jaka Fadli and Dzikra Fauzia. To help test coral resilience under controlled conditions, the guests and crew

from Seahawk assisted in the careful collection of coral samples. Two small fragments were taken from the same colony using garden shears, cut low enough on the branch to allow for replanting later. Back at the station, one fragment was placed in a tank set to match its natural ocean temperature. In contrast, the other was placed in a tank where the temperature was gradually increased by one degree Celsius each day, mimicking the heat stress corals may face in the warming oceans of the future.

This controlled trial setup allows researchers to isolate genetic differences in heat tolerance. Some corals bleach within days, while others retain their colour much longer, potentially indicating naturally heat-resistant strains that could be key to reef recovery in a warming climate.

By observing when the coral begins to bleach, turning white as it expels the algae it depends on, scientists can identify which individuals are more tolerant to rising temperatures. These insights help us understand which corals are best equipped to survive in a warming world.

Helping Reefs Heal: Reef Stars

To support coral growth, the team also uses special hexagonal steel frames called Reef Stars. These act like underwater scaffolding, helping broken coral pieces attach and grow back strong. Over time, these “reef spiders” help rebuild damaged areas faster, giving the reef a chance to recover.

Made from marine-grade rebar coated in sand, these structures are designed to mimic the natural reef typography, stabilising loose rubble and increasing coral survival rates. Field studies have shown that coral growth on Reef Stars can reach 25 cm per year, an impressive rate in reef terms.

A Personal Call to Action

One moment stayed with me: the realisation that fish can swim away from warmer waters, but coral can’t. It is fixed in place, vulnerable, and absolutely vital to ocean life.

This work isn’t just science, it is a survival plan. As we sailed away from Kalig, I felt a deep responsibility to share this story. Protecting coral reefs means protecting the oceans we all depend on.

If we want vibrant, thriving oceans for future generations, it starts with understanding and caring for coral today. Conservation isn’t just about saving something beautiful; it’s about saving life itself.

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.

Grey Reef Shark and divers

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.

BRUV

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.

Science team in stormy weather

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.

3 passes at Tahanea atoll

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.
