Sharks and the ocean’s twilight zone: Some female great white sharks can deep dive for hours

Boston Herald

Much of the shark focus around the Cape is on great whites roaming close to the shoreline as they prowl for seals, but researchers are finding out that several sharks are actually diving deep into the twilight zone out in the middle of the ocean. Scientists at Woods Hole Oceanographic Institution on Cape Cod are researching the sharks’ deep diving behavior and how sharks’ bodies have evolved to handle these deeper conditions. They’re learning that deep diving is far more frequent and extensive across species than previously thought, said Simon Thorrold, a senior scientist in the biology department at the Woods Hole Oceanographic Institution.

The twilight zone can be found 200 to 1,000 meters (about 650 to 3,300 feet) below the ocean surface, at the point where the sun’s rays can no longer reach, according to the Woods Hole Oceanographic Institute (WHOI) in Massachusetts. Because it’s so deep and there’s no sunlight, it’s cold and dark.

Today, the U.S. is a powerhouse of ocean science research and marine engineering, led by organizations such as Woods Hole Oceanographic Institution, Scripps Institution of Oceanography, and the Monterey Bay Aquarium Research Institute, among others. These are the Jet Propulsion Laboratory, Ames Research Center, and Goddard Space Flight Center of ocean exploration.
