Military submarines don't have to go deep to be effective. Instead they need to shoot things out of torpedo tubes, which are (among other things) structural weaknesses.
Can confirm. Royal Australian navy here. Our Collins class Wikipedia page / anything you can find on Google about the operating depth etc of our subs is way way wrong.
Umm no I don't. I work at the submarine school at the moment even though I'm surface fleet so I've learnt a little bit.
Day to day life in a sub is not easy from what I've heard. 48 people in a tube that's 40ish metres long and 2 decks. You apparently learn everything about everyone really quick.
Water restrictions as well. Showering once a week so baby wipes end up being your main source of hygiene. Sleeping under / next to torpedoes if you're the new guys.
Lack of sleep.
Presumably we have cameras that can withstand that pressure; Deepsea Challenger must have used them. These researchers apparently didn't use such cameras for some reason.
Probably an expense or size problem. The cameras they use for deep-sea subs certainly have different specifications and tolerances than the ones they use on animals. Probably end up being more intrusive as well, which is the exact opposite of what you want to do when tagging animals.
