If you have 100 ocean survey ships scanning the ocean floor 24/7 moving 6 knots with 1 km wide side scan sonar, it takes over 900 years to map all oceans.

- gleglegle 3y ago10,000 autonomous ships to do it in 9yrs?
- dylan604 3y agowith what funding for that many ships for what purpose of recovering the investment?
- wolverine876 3y agoSometimes purpose isn't about money. Though funding would be an issue.

- checker365 3y agoCould I know your formula? ocean : 361,000,000(km2) 6knots: 11.1km/h 361,000,000/(24*365) = 41,096(km2/day) 41,096/11.1 = 3,702 so, 100 ships take 37years? Thank you, klaus23!
- Arech 3y agoDid it ever occur to you that you take a square kilometer as a linear kilometer in your calculation?
- mierz00 3y agoDon’t the ships have a kilometre wide sonar scan? Therefore traveling 1 kilometre counts as scanning 1 kilometre squared.
- Klaus23 3y agoI'll throw my result into the ring. I get 37 years: <https://www.wolframalpha.com/input?i=%284*pi*%2812733km%2F2%29%5E2*0.708%29%2F%28%281km*6knots%29*100%29+to+year https://www.wolframalpha.com/input?i=%284*pi*%2812733km%2F2%...>
