More than a dozen former workers report workplace abuses they say they suffered at One Ocean Diving, which has been operating cageless shark tours on the North Shore for more than a decade.

At the height of the Covid-19 pandemic, Mariana Perez-Varona was doing cancer research at a hospital in Portland, Oregon, when she saw a job posting for a safety diver position with One Ocean Diving in Hawaiʻi. She was a marine biologist and a divemaster — the first tier of professional certification in scuba — but because of the pandemic, she hadn’t been diving in a while. The job looked like the perfect opportunity. “It was my chance to get back in the field,” she said. She moved to Oʻahu and started what she thought would be the job of a lifetime: helping run cage-free shark tours and doing research and conservation work for Ocean Ramsey. Somewhat of a shark conservation celebrity, Ramsey has gone viral for her videos swimming alongside tiger sharks and great whites. She’s been the focus of two documentaries — including “Shark Whisperer,” which came out on Netflix last year. Many in the marine biology field take issue with Ramsey’s hands-on approach, including sometimes gripping the dorsal fins of the sharks, and some of Perez-Varona’s former professors had questioned Ramsey’s academic credentials. But still, Ramsey has been influential in bringing awareness to shark conservation, and Perez-Varona couldn’t...

Few people on Earth have seen a polymetallic nodule 4 kilometres under the ocean, but Rob McCallum is one of them. "They are anywhere between the size of a potato or a baseball and they are black," he said. Mr McCallum is a divemaster and founder of EYOS Expeditions, a firm that specialises in deep-sea diving operations. He has explored the depths of all five of the world's oceans, including the Mariana Trench, and has made trips to the wreck of the Titanic and the Bismarck. He has also descended into the Clarion–Clipperton Zone — a vast area of the Pacific that's been identified for prospective deep-sea mining projects. This area contains countless polymetallic nodules formed over millions of years. They contain valuable critical minerals including nickel, cobalt, copper and manganese, used to create batteries for phones and cars. Mr McCallum likens them to nuggets from Australia's gold-rush era. He's not alone. Billions have been invested in exploration and research into deep-sea mining, as governments and companies position themselves to tap into a new source of critical minerals. United States President Donald Trump last year signed an executive order to accelerate seabed mining in US and international waters, arguing it...
