Is there a reason why we don't use migrating fishes like sharks as living mobile sonar platforms? They could gather intel of a large section of coast and nobody would know anything.

Because the sonar would probably disturb the ecosystem
It's just fish
If you disturb the migrating patterns of the fish, then dolphins wont have food to say the least which means their migration pattern change, if not die out.
Can't we make something that doesn't fuck up with the delicate senses of a shark? I mean we can attach satellite trackers, why not sonars?
Because sonar is sound, and sound (especially underwater) REALLY FUCKING HURTS IF IT'S VERY LOUD
Sharks are really sensitive to electric fields. Just having a a capacitor strapped to it would probably cause it to freak out and not behave naturally.
Microchip tags seem to work okay, so no, that's a bit of an exaggeration
Megasharknado inbound!

240 decibels, baby. No wonder wales kill themselves
Jesus fucking christ, imagine hearing something like a jet engine point blank only twice as loud, 24/7, and since it's in water you can hear it from hundreds of miles away.
You’re not just hearing it at that point, your whole body feels it
>jet engine point blank only twice as loud
10,000,000,000 times as loud. The decibel is not a linear measurement unit, it's a logarithmic scale. A 10 decibel difference means 10 times more powerful. 80 decibels is 100 times louder than 60 decibels etc. A jet engine is only 120-140db, SURTASS is 215-240db.
The only reason that anyone is every surprised that naval active sonar makes whales deliberately kill themselves by crushing their own lungs is because schools don't bother teaching SI units.
Decibels are not in the SI
Lmao yep, my bad. Sick self own.
It's about 400 times louder, still pretty awful.
Sonar is expensive and you want to entrust it to a fucking fish?!?!?!
What does a construction equipment manufacturer gain from tracking sharks?
Those high performance shark bladder gear lubricants don't grow on trees
I wouldn't worry about it.
It's just a project that's funded by random corporations. Their site lists Yeti as a sponsor right now, they make coffee mugs.
Remember that EVERY woman wants to go to college to study marine biology. There IS a culture around this.
What makes you think "we" don't ..?
>implying we don't
this is a joke thread yet for serious, up to date, deep sea ocean floor mapping the need is for autonomous, nuclear powered drones that travel the oceans criss crossing it systematically with sonar mapping. Continously examining the floor while relaying the data through sats back to servers via hard wired communication boys
If some of them fail and sink nook reactor in the average depths is not going to do much. God knows there are more then enough of them already lying in the sea. Biggest prohibitor is lack of initiative which would come only with financial insentives. Like deep sea mining, if it were profitable or military needs. Reminder GPS started out as a US mil funded program before being opened up to civilian use. Now its everywhere. Next big similar advancements like Starlink have, yet again, the US military as the early big risk investor
just use robot sharks
We have been found out. Shut it down.
What you want is sea gliders

That page is about a chinese models, but i know the frogs make some as well with the Alseamar company

I'd be very surprised there aren't other countries making them, including the US
You can fit passive sonars, conductivity, Temperature, Depth sensors, turbulence meter, Turbidimeter, chlorophyll sensor, dissolved oxygen sensor, nitrate and other biochemical sensors.
It can also carry Acoustic sensors such as ADCP (acoustic Doppler current profile), underwater acoustic communication,and hydrophones
Because active sonar is lethal to anything near it when it goes off dumbass.
Because then Asians would eat our sonars.
People would notice the sonar pings and the sharks wouldn't handle having a sonar attached to them very well. You know what animal already has a built-in sonar, whales. Sperm whale calls can be up to 230 db, enough to kill a human if they're too close. We just have to learn to communicate with the whales and then have them relay their findings to us. Another possibility is we attach a sonar probe to the whale, that's specifically designed to interpret a whales clicks and calls, essentially using the whale's own voice as the sonar ping.
>d to them very well. You know what animal already has a built-in sonar, whales. Sperm whale calls can be up to 230 db, enough to kill a human if they're too close. We just have to learn to communicate with the whales and then have them
tell the aliens not to blow us up
But where are the nuclear wessels?
yeah well double dumbass on you!
Because sonar is really fucking loud. Like 'blow your eardrums if you were swimming even close by, and kill you outright if you were right next to it' loud. Sound propagates more easily underwater, but that doesn't mean ANY sound travels for miles and miles and miles. Only the loudest do.
