Why Do Deep-Sea Explorers Wear Those Tiny Knit Caps?
The prospect of deep diving may seem exciting and include moments of thrilling discoveries, but the trip itself is hardly a thrill ride. Vehicles usually travel at a maximum speed of only 2 or 3 miles per hour, so divers sense little of the motion of ascent and descent. Since it can take several hours to reach the seabed, most of the trip can be spent just passing time. Pilots and solo explorers like Cameron must be mindful throughout the journey, but passengers may simply gaze out the porthole (though the water goes dark after about 10 minutes), read, or doze off; some occupy themselves with a computer or music. When resurfacing, however, turbulent waters around the surface can feel like an amusement park ride, or worse, and many craft don?t have seats or seat belts.
