There's no other way than sonar to detect things like mountains underwater?
That's interesting. Seems by now we might have something else that does that. A way to use sonar that obfuscates the source of a ping, underwater lidar, submarine drones, something?
- ohyeshedid 5y agoWhat signal would you send that isn't detectable by anyone but you?
- tikwidd 5y agoAn array of tactile antennae/feelers?
- jazzyjackson 5y agonow you’re thinking like a catfish! i like it
- SomewhatLikely 5y agoEntertaining the idea of a probe sticking out the front led to a realization. The problem is you're never going to stop in time if you're at speed. You need to know well in advance that something's there.
- PeterisP 5y agoPerhaps a sound signal that's a copy of something naturally occurring, e.g. by sea animals.
- oblib 5y agoThat came to mind for me too.
- jakear 5y agoFleet of small scale autonomous drones? Bonus points if they're water soluble.

- bell-cot 5y agoThe generally accepted way to detect large geological features underwater, if you're not a survey ship (moving slowly, running multiple loud sonars, etc.) is to have and use accurate navigation charts. Wretched shortcomings in that regard seem well-accepted as the cause of the USS San Francisco's mishap.
