My H2O project questions

My primary question for the H₂O Project is “The ratio between sea life and human activities at five popular beaches in San Diego.” which I also might change to three depending on how the first one will turn out.  So obviously I am not going to snorkel to count the fish with a click counter, instead, I would much rather find this information on a website, and same with humans if they are too many. I think that if I can actually get that information that it would be great to prove if having humans at almost all the beaches is bad for the sea life, also at places that we probably need to rethink if the population ratio is too off.

Then my second research question is “How the tides affect local birds at OB”. OB being Ocean Beach of course is a question that I want to use mostly because I want to make a web calendar and I want to see what it actually does. So at certain tides, the water flow has got to be a sweet spot that keeps fish there, attracting the birds to a certain time (not having to count stupid fish). Then again those stupid birds may come at lunch hour to pick up left over food from lazy people.

I might need to go over the question (s) some more, but there first one I know what I am getting at but getting there is the hard part. The second one is obvious but is hidden from my sight as the fog will slowly roll away. That is basically my biggest concern, but the biggest improvement I need to improve on is #1, since it is hard to achieve “counting fish” accurately as imagined.
