science ๐ Deep sea exploration is way slower than we think ๐ฎ
Even with a fleet of 1,000 deep-sea vehicles, surveying the entire deep seafloor would take over 100,000 years. This estimation comes from a 2025 Science Advances paper led by Katherine Croff Bell of Ocean Discovery League. The analysis used 43,681 visual dive records spanning from 1958 to 2024 to calculate coverage rates. The mean coverage rate across nine systems was determined to be 2.9 square kilometres per year. Consequently, researchers suggest shifting focus to strategically sampling areas rather than aiming for total coverage.
