What are the chances of getting to visit the Deep Sea if that’s your specialty?

I’ve always been deeply fascinated by specifically the deep sea, the main catalyst being observing siphonophores in videos of explorations. Also the techniques of scattering light of other creatures, along with the way the different parts of the ocean work symbiotically to keep balance and the way humanity is disrupting said relationship. It’s all fascinating.

I’m in my early 20s equipped with nothing but a GED, but am preparing to go to school next year to get my basic classes out of the way locally before trying to find a reputable school to study at on the coast. I’m aware I’m way behind the curve of where becoming a higher level marine biologist would be feasible, but the work would be worth it if just once in my life I got to take an expedition to the deep sea.

I have no contact with anyone who would be able to answer my question, so I’m selfishly impeding on this subreddit of people who are qualified to tell me to fuck off. I’m not saying I wouldn’t enjoy the work if I never got the opportunity to visit the deep, as the science behind it all is fascinating. I’d be more than eager to do my time in labs and doing grunt work, traveling across the world as slightly better opportunities present themselves, but that really is my life’s dream.

Idk any words of wisdom are more than welcome
