...there really aren't satellites 'just taking photos' of the ocean. You might have a spy satellite taking pictures of a naval exercise. I think you are underestimating a) how vastly big the ocean is, and b) satellite capacity (most intelligence satellites are over land).
71% of the world is ocean. The ocean is vast, and most of it has very little going on. Last month someone washed up having been lost at sea for over a year, having only seen two or three ships (which didn't stop). A few ships in 13 months.
