Three years later, another French-born swimmer, Benoît Lecomte, swam from Hyannis in the US to Quiberon in France, covering 3,716 miles in 73 days. He, too, was tracked by a shark – this time for five days – and he too declared himself the first person to cross the Atlantic.
Atlantic Ocean swim
During his 73-day, 3,716-mile (5,980 km; 3,229 nmi) journey, Lecomte was accompanied by a 40-foot (12 m) sailboat that had an electromagnetic field for 25 ft (7.6 m) to ward off sharks.
Ben Lecomte has swum over 1,753 miles through the Pacific Ocean since he set out from the Japanese coast at Choshi in June. Along the way, during a trip he hoped would be the first recorded trans-Pacific swimming passage, he's run into turtles, been stung on the nose by jellyfish, and encountered mako sharks.
Pablo Fernandez holds the Guinness World Record for the longest ocean swim at 250 kilometers, which converts to 155.34 miles.
The NOAA recommends only swimming at beaches that are guarded by a lifeguard, and, barring that, reminds swimmers to never, ever swim without anyone else present. Before you dip your toes in the water, be sure to find the nearest lifeguard stands, and be ready to alert them and call for help at any signs of trouble.
Ocean swimming is significantly more challenging than swimming in a pool or most other places because you must contend with waves, the change of the tide, the slope of the beach, and strong currents that may be present even when the surface appears calm.
Shark attacks are very rare, and many beaches have shark nets to deter sharks. However, it's always smart to avoiding swimming at dusk, in river mouths and a long way offshore. This will help to further reduce risk. The safest place is always between the red and yellow flags.
Only three people have ever done that, and one was a U.S. Navy submariner. In the Pacific Ocean, somewhere between Guam and the Philippines, lies the Marianas Trench, also known as the Mariana Trench. At 35,814 feet below sea level, its bottom is called the Challenger Deep — the deepest point known on Earth.
Trent Grimsey holds the record for the fastest swim across the channel, completing it in 6 hours and 55 minutes. The shortest distance from New Zealand territory to Australian territory outside Antarctic claims is from Auckland Island to Macquarie Island – a distance of approximately 617 kilometres (383 mi).
Strel swam the Danube River setting new records a couple of times, once for 84 hours non-stop and once for 58 days. But American triathlete Mimi Hughes swam for longer – 2,800 km (1,740 miles) of the Danube River in 89 days, according to WWF Global.
In the summer of 1987, the American swimmer Lynne Cox braved the frigid waters of the Bering Strait to swim from the United States to the Soviet Union. Twenty-five years on, now aged 55, she recalls how her actions in the waning days of the Cold War eased international tensions.
Severinsen swam 202 meters (662.73 feet) underwater on a single breath in La Paz, Baja California Sur, Mexico.
WASHINGTON, Feb. 6, 2023 /PRNewswire/ -- Yesterday the Chilean ice-water swimmer, Bárbara Hernández, made history by being the first person to swim 2.5 kilometers in the frozen waters of Antarctica.
The deepest place in the ocean measures 10,935 meters (35,876 feet) and is found in the Pacific Ocean's Mariana Trench, at a place called Challenger Deep.
Paula Stephanson swam across Lake Ontario in 1996 at the age of 17 in 22 hours 30 minutes. Subsequently, she swam Lake Erie (1998, 18:23, aged 19), Lake Huron (2000, 22:26, aged 21) , Lake Superior (2007, 13:15, aged 28), and Lake Michigan (2009, 25:38, aged 30).
One of the biggest challenges of ocean exploration comes down to physics. Dr. Gene Carl Feldman, an oceanographer at NASA's Goddard Space Flight Center, explains that the ocean, at great depths, is characterized by zero visibility, extremely cold temperatures, and crushing amounts of pressure.
We have explored less than 5% of Earth's oceans.
The discoveries we have made are vast, enchanting, and, often, alarming. And still, we've barely dipped beneath the surface.
The discovery of microbial mats — bizarre-looking, filamentlike clumps of microorganisms — living off chemicals from altered rocks 35,803 feet (10,912 meters) beneath the surface of the Pacific Ocean comes from samples and video collected by an unmanned lander, part of movie director James Cameron's mission to the ...
All of the beaches in Australia are technically Crown land, meaning they're for public use. As a general rule of thumb, any land that high tide touches — known as the high water mark — is Crown Land.
To reduce your risk, don't swim too far from shore, stay in groups, avoid being in the water during darkness or twilight, don't go in the water if you are bleeding from a wound, leave shiny jewelry at home, and avoid brightly colored swimwear.
Throughout the 1800s it was illegal to swim at Sydney beaches during the day. This was because people believed it was wrong to be seen in little or no clothing in public spaces. People could swim only in the early morning and late evening, and men and women could never bathe together.
Fresh water lacks the high saline content of oceans and seas, and as such, does not offer the same buoyancy profile of salt water. This means that swimmers need to work harder to maintain good body alignment and a high position in the water.
Pools are significantly safer than the ocean. While swimming in the ocean can be thrilling, you also face a plethora of potential dangers, such as sharks, jellyfish, and other sea creatures, unpredictable waves, and riptides that can threaten even the strongest swimmers.
Any air filled crevice of the human body would collapse in the blink of an eye under this pressure. Lungs filled with air would collapse and the bones would crush. Mariana Trench is the deepest location in earth's crust.
