What environmental data would you list for an aquatic habitat?

For an aquatic habitat, key environmental data to consider includes water temperature, pH levels, dissolved oxygen concentrations, and salinity. Additionally, data on nutrient levels (such as nitrogen and phosphorus), turbidity, and the presence of pollutants or contaminants are important. Habitat structure, such as substrate type and vegetation, as well as flow rates and water depth, also play crucial roles in assessing the health and biodiversity of the ecosystem.
