The Deepest Map

Today, only 25 percent of the seafloor is well mapped. When Vescovo set out to score his record, the exact deepest location in each ocean was unknown. Bongiovanni, Vescovo and their crew had to chart these regions in detail before each dive.
“Traditionally, captains never cared about the seafloor as long as it stayed far enough away from the hulls of their ships,” journalist Laura Trethewey writes in The Deepest Map. The book explores humankind’s quest to map the seafloor, framed around Bongiovanni’s adventures.
Seafloor topography has been a big concern for militaries patrolling Neptunian frontiers with nuclear submarines and companies facilitating intercontinental communication via subsea cables (SN: 4/10/21, p. 28). In recent decades, seafloor data have become crucial to the deep-sea mining industries searching for metals needed to produce green technology.
