Director says the focus on records is detracting from deep sea science and exploration.
Cameron said his motivation for going to the Mariana Trench was not to break records, but to build a submersible and see some of the deepest parts of the ocean. Records, he said, were not at the forefront of his mind, adding he"never claimed to have gone deepest." Instead, Cameron says, he felt he shared the record with Don Walsh and Jacques Picard, who dove into the Challenger Deep in 1960.
"They observed a plain that was flat within a meter or so for several kilometers east and west, as well as north and south. So our conclusion back then, and today, is that it's not really possible to go deeper." Many things can affect measurements taken, including changes to temperature and the salinity of the water."Just as you can't step in the same river twice, you can't measure the same water column twice," Cameron said."This creates error margins, for the best instruments of plus or minus 10 meters ."

Over 80 percent of the ocean is"unmapped, unobserved, and unexplored," the NOAA says.
