Niki UR Osmosis Jaws

I was lucky enough to stumble upon an article of a 30 year study of the Indian River Lagoon and it's role as a bull shark nursery during the spring, summer and fall. The synthesis combined data collected over a 30 year time frame and included several different studies done in different areas of the river system. Age 0 sharks seem to prefer northern areas and its warmer temperatures and lower salinity, such as the Mosquito Lagoon area. Included in the article were CPUE rates for different types of gear and the different areas over the 30 year span, and I've come to the conclusion that what I may have had in mind for my project probably isn't feasible. The best way for me to collect data that would produce results would be to drive much farther south than I had anticipated, and there is the added obstacle of equipment.

Changing gears, I only have an inkling of where to begin! Bull Sharks are able to live in lower salinity areas because of  their osmoconformic nature, the process in which the shark changes the way their kidneys function to produce large amounts of watered down urine in order to maintain proper balance between the shark and environment.
The ability of some marine animals to inhabit these environments with such different salinity concentrations is something that interests me, and seeing as I live a mere 2 blocks from the beach and river, and want to take advantage of the ease of access to these two different sites. Possibly an experiment on the comparison of water quality measurements from the ocean to the Halifax River? I live several miles from the inlet and wonder what the salinity, water clarity, temperature and energy levels are for the river versus the ocean at the same position across the street.
