It looks like you've got a clear idea of what you want here, but I'm not getting much from it.
So far, all i see is a summary of sorts. Nothing's pulling me in. I'm getting zero character.
I find it risky to start stories with a description. It's long winded and can get you and the reader off on the wrong foot. I've read books that i gave up on because the intro didn't grab me. To an extent it was boring (i eventually DID read on, and it turned into a good book).
You want to make your readers want to see more, demand more. Like the GTA V trailer - people are desperate for more, they'll suck off a horse just for a screenshot. Put that in writing terms, and you get suspence, mystery. You get a question that we need to know the answer to.
I'm not seeing any of this here tbh.
There is no trigger - no event that begins the story. Some guy wants to explore old wrecks and things? Ok. Why? What's his motivation?
I think this has potential, but i can't see where it's going at the moment. I always try to start my stories off with a bang - my personal style usually involves an action scene that is meant for people to go "ooh..." Then when the descriptive start arrives people can go with it.
Maybe you should consider a prologue? A short scene that will excite people. A scene that makes people sit up and take notice. Then you can start the next chapter like the above.
I've noticed your relatively new too - welcome to the WD, and don't feel hard done by by my words, I'm sharing my opinion in the hope to help you improve your work, which as is said, has potential, I'm jst not feeling excited by it.
