A British woman pushed the boundaries of human endurance to new levels yesterday as she dived 96 metres (314ft) below the surface of the Atlantic and back again on a single, very deep, breath.
Sara Campbell — “part woman, part fish” — broke the world record in the extreme sport of freediving, whose participants dice with death by submerging themselves to lung-crushing depths without breathing apparatus.
Holding her breath for three minutes 36 seconds, she went deeper than any female freediver has gone before without weights or equipment to hasten her descent, or an airbag to speed her back to the surface.

Later in the story they say "The world record for a person holding their breath under water while static is 10 minutes 12 seconds. "
Do you smell ‘fish’?
Not guilty.
I can’t tune a woman, but I can tuna fish.
Mehgan Heaney-Grier is even less guilty as free divers go.
yes she is..
I was told once that the deeper a person goes, the less buoyant your body is. Just wondering if anyone knows if this is true.
She is no Tanya Streeter,
I respect this woman’s accomplishments, but I’d be leery of promoting this “sport.” It’s pretty suicidal. If you are a competitive swimmer or a shot putter, you are easily rescued if you have an issue. In this activity, obviously, you’re a goner.
It just feels that way when you have tons of water above you
“I was told once that the deeper a person goes, the less buoyant your body is. Just wondering if anyone knows if this is true.”
It depends but for the most part no the buoyancy of your body doesn’t change. Liquid doesn’t compress and most of your body is water and other liquids.
Your lungs compress at this level.
What does change is the equipment you take with you. The little air bubbles in the wet suit compress and the air in the buoyancy vest does as well. When it compresses it provides less buoyancy.
Miscalculate at extreme depths and you can find it impossible to ascend.
I thought maybe the pressure compresses your body tissues thereby making you more dense...in other words, less buoyant.
Whats Obamas excuse he looks like he is wearing a wetsuit all the time
Its a very dangerous sport but it is a sport.
Aha. So this is only with scuba divers, not free divers...that the buoyancy thing becomes an issue?
Cuz he’s SLICK and SLIPPERY.
It compresses your lungs but not the rest of your body. And no you can’t feel it. Of course I haven’t been that deep, I stopped at just over 100 feet.
Going 300+ feet deep with or without air tanks is dicey and the margin for error is razor thin.
“Aha. So this is only with scuba divers, not free divers...that the buoyancy thing becomes an issue?”
Not really, your lungs are a major component of your buoyancy. At normal depths you can you your breathing to help manage your depth.
At 300 feet your lungs are providing much less buoyancy than at 15 feet. If she blacked out she would not float up. If she can’t kick she also won’t be able to ascend.
