Someone once dove a whopping 831 feet into the ocean
Compared to the actual deepest point of the ocean (the Mariana Trench stretches down nearly seven miles), 831 feet may not seem that deep. But when you consider that this intrepid diver was accompanied only by a wetsuit, a weighted sled, and an air balloon to help him float back to the top—without even scuba gear—his accomplishment seems a lot more noteworthy.
It’s the deepest part of the ocean ever reached by a free-diving human (as opposed to a human inside a machine). The diver, Herbert Nitsch, completed his historic feat in 2012, and he currently holds 33 separate world records in free diving. Through rigorous training, he’s been able to increase his lung capacity to more than twice the usual amount of air.
