Legendary American explorer John Moyer has dived many wrecks along the North American eastern seaboard. But his name is synonymous with the Andrea Doria wreck, on which he made over 120 dives in the '80s and ‘90s, salvaging artifacts, and conducted in-depth research. In this interview by Andrea Murdock Alpini, we gain insight into his life and deep relationship with the Andrea Doria.

Once a year, the Solitude One liveaboard makes the 800km journey from Anilao down to Surigao in the Philippines, stopping at Verde Island, Romblon, Ticao, Malapasqua and Southern Letye on the way. On this dive cruise, one can dive with whale sharks, thresher sharks and manta rays, or do super-macro underwater photogra­phy and even black water dives. Mattias Sellin shares his adventure.

Although striped marlins (Kajikia audax) are slower than some of their billfish cousins, their 50-mph speed was plenty fast for me. I tried to swim alongside this stealth bomber of the sea as it worked a baitball to separate individual sardines from the silvery mass. Amos Nachoum has the story.

Considered the longest continuous and second largest in the world, the reef systems of New Caledonia have some of the most diverse concentrations of reef structures on the planet, providing a home for a vast diversity of species, including 2,328 fish species. It is an important site for nesting green sea turtles, and there are also large populations of dugongs and humpback whales. Pierre Constant shares his adventure.

Well-trained divers all know that they need to equalize their ears and sinuses as they descend. Usually, this is an easy process. However, there are some medical conditions that can make this more difficult. Technical rebreather diver and underwater photographer Dr. Michael Rothschild is a pediatric ear, nose and throat specialist in New York. In this article, he walks us through the common causes of nosebleeds during diving, and how to avoid sinus blocks associated with changing ambient pressure that can cause nasal barotrauma and bleeding.

Since 1889 the Pilgrim Hall Museum in Plymouth has had 109 timbers from a shipwreck believed to be the Sparrow-Hawk that sank in 1626. In March 2022, an international, multiyear study on the timbers provided the best evidence that the wreckage is from the Sparrow-Hawk.

A new study by researchers at the universities of Exeter and Bristol showed that “traffic calming” boosts breeding of reef fishes. For a whole breeding season, scientists implemented traffic calming on three reefs, decreasing the number of boats within 100m and reducing their speed.

According to new research conducted by marine biologists from the Marine Biological Association (MBA) and the University of Southampton, lethal collisions between whale sharks and large ships are greatly underestimated and may be the cause of declining populations.

More international collaboration is needed to safeguard the future of the more than 6,000 coral species, according to a new study into controlling the effects of climate change on these organisms. To this end, the study's authors advocated for a network of “mesoscale sanctuaries” (large-scale protected areas) across borders.
