(Expedition) Stuck with no clue to progress (spoilers)

Hi all,

I have just got to the point where the professor asks me to get AcoNR from Abyssal Station Zero elevators at L2.  However when I get to L2 there are no elevators and only a subsphere. 

Now from what I found on the internet I have to search for a submarine somewhere, but for immersions sake can someone tell me if I have missed any in-game clue/message/dialogue that points me to where the submarine is (or hints that I have to find one in the first place)?  It's kinda immersion breaking that I have to look on the internet for the next step.

Thanks for any help in advance.

if I recall correctly there's no dialogue pointing you to go find the submarine, but look carefully through the shipment documents again and note the coordinates of any research facilities you haven't been to yet.

i could tell you more but it sounds like you want as little as possible

Luckily I kept a save at JSHQ so I can go back to look at the logs, and I see what you mean now.
Thanks so much man, and thanks for keeping it spoiler free lol.
