Evidence Suggests Rare Orca Cannibalism in North Pacific

Severed killer whale fins found on a remote Russian beach may point to rare cases of orca-on-orca predation, raising new questions about why some killer whale populations live in tightly bonded family groups.

Ecology & Science

Researchers studying killer whales in the North Pacific have uncovered evidence suggesting that orcas may occasionally prey on other orcas, a behaviour rarely documented among the ocean’s top predators.

The clues come from two severed dorsal fins discovered on Bering Island in Russia’s Commander Islands. The fins bore clear tooth marks and other signs of feeding damage, indicating they may have been torn from killer whales and partially consumed.

USS Yorktown Explored After 82 Years Underwater

NOAA remotely surveys the iconic WWII aircraft carrier and discovers a 1940s vehicle and a preserved flight deck.

Wrecks & Archaeology

Eighty-two years after it sank during the pivotal Battle of Midway, USS Yorktown has been revisited in a landmark deep-sea expedition. Using remotely operated vehicles, researchers from NOAA have conducted the first detailed visual survey of the wreck, revealing remarkable preservation and an unexpected find—a 1940s-era vehicle resting on the hangar deck.

Vanuatu: Pacific Island Adventure

The Pacific island nation of Vanuatu is a remote destination in Melanesia that offers diverse diving on reefs, wrecks and in freshwater springs that are home to a number of endemic species. Pierre Constant shares his adventure there.

It was a long way from Europe to Vanuatu (formerly the New Hebrides) in the western Pacific Ocean. The Air France flight from Paris took me to Tokyo, where I had to change to an Air Calin flight to Noumea in New Caledonia. When I arrived there two days later, just before midnight, I was jet-lagged—only to discover, with a sigh and some stupor, that one of my checked bags had not appeared on the conveyor belt. Air Calin did not track bags on their computers. Of course, their agents were keen to hand me a “lost” claim form swiftly, so they could get rid of me with a smile. 

Pacific Coral Reef Shows Increase in Climate Resistance

Coral reefs in one part of the Pacific Ocean have likely adjusted to higher ocean temperatures.

Ecology & Science

The ability of coral reefs to adapt to changing ocean temperatures is a pressing question in marine biology.  

Coral reefs are currently experiencing significant declines. These declines are primarily due to marine heatwaves, which lead to widespread coral bleaching and mortality. Understanding how coral communities can adapt to increasingly severe and frequent marine heatwaves is crucial for their survival in the face of climate change.

Bikini Atoll: A Journey into its History and Wrecks

A far-flung location in the Pacific, which can only be reached via liveaboard, Bikini Atoll in the Marshall Islands is the site of a fleet of WWII wrecks. Sunk during post-war nuclear testing, the wrecks are now encrusted with marine life. Brandi Mueller shares her adventure there.

Bikini Atoll is arguably one of the most remote and adventurous dive locations left on Earth. It is literally in the middle of the Pacific Ocean; depths here allow only trained technical divers to reach the wrecks and the atoll feels (and has been) abandoned and deserted in every way. But Master Liveaboards has returned to the location, post-Covid, to bring divers to the wrecks in luxury and comfort—even with internet connection to the outside world via Starlink. I cannot think of a better way to dive this bucket-list location.

Muck Diving: It’s a Small, Small World on Guam

Muck diving on Guam was little known by divers until a few years ago when local residents started posting images online from muck dives. Simon Pridmore and Steve Wolborsky tell the tale.

Twenty-five years ago, I opened a dive center in Guam called Professional Sports Divers. This was the first dedicated technical diving center in the Western Pacific, but we also taught people to dive and took fun divers out to see Guam’s reefs and wrecks.

Studying wild whale sharks in the Galapagos with underwater ultrasound and blood sampling

In a world-first, underwater ultrasound and blood sampling have been used successfully on wild free-swimming whale sharks in the Galapagos to observe their reproductive states. Don Silcock interviews Dr Simon Pierce of the Marine Megafauna Foundation to learn more about this ground-breaking research.

Lifou in New Caledonia

Stretching over 500km, the Loyalty Islands of New Caledonia in Melanesia are a tropical oasis in the Pacific. It is here that one can experience the beautiful underwater world of Lifou, home to a diverse array of marine life. Pierre Constant shares his adventure there.

It was an early morning departure for the Betico 2, bound for Lifou Island. Check-in was at 6 a.m. at the ferry terminal in Noumea, the main port of New Caledonia. With the maximum luggage allowance at 15kg, plus a 6kg carry-on, I had to come one day early to bring my 42kg of excess luggage as cargo (comprising dive gear and underwater photography equipment). As a diver, there is no other option! Flying also limits you to 15kg max.

Galápagos Islands

An enchanting and ecologically unique place, immortalized by Charles Darwin’s seminal work on evolutionary biology in 1859, the Galápagos Islands hold a revered spot as one of the truly magical locations of the world. During pandemic times, when stillness and quiet replaced the cacophony of tourists, it seemed even more captivating. Brandi Mueller reports.

It was an hour before sunset, and I was snorkeling at Playa Punta Carola, a blinding white crescent of a beach with jet-black lava rocks marking both edges. Looking closely, some of the rocks moved, giving away that they were actually camouflaged marine lizards shifting or expelling salt from their noses with a loud puff.

I have been fortunate to visit Fiji in years past, and it is one of the few dive destinations that I have returned to on multiple occasions. The country’s amazingly colorful coral reefs, abundant fish life and beautiful landscapes, as well as the warmth and caring of the Fijian people, keep me coming back. I look forward to revisiting favorite dive sites, exploring those yet unknown and embarking on adventures alongside friends old and new. This is a country steeped in tradition and culture that I could move to tomorrow and feel right at home.
