On Artist boat we learned about many things, for example we went over PH ,salinity, and turbidity.
Ph is the acidity in the water it can effect the population of the fish if it is two acidity then the fish could die because they are breathing in that acidic water. Salinity is the salt in the water it could also effect the fish and plants and for example the blue crab normally hangs around in saltier water , but during winter or when they are about to lay there eggs they move to deeper water where it is less salty. Turbidity is another thing we learned it determines how murky the water is and this can effect the fish because if it is to murky then the fish cannot get the oxygen out of the water and they won't be able to breathe. We need to know this type of information because the population of the fish can die and we need to prevent that from happening . This information is also important for marine biologist and people who own swimming pools because  they test all of these things on a daily basis . People need to respect these tests because they really do help the ecosystem and our environment.
