Calm and Cool Among Tumult and Fury

I remain calm and cool among tumult and fury,
I hide treasures and creatures you could hardly fathom,
I will crush those I welcome in deeply,
I am dark yet beautiful.

What am I?

Thousands of treasures have been lost in sunken ships, and amazing creatures live at deep depths of the ocean. At extreme depths, the pressure is crushing. It is extremely dark deep in the ocean, yet also beautiful.
