[1] Aquatic scientists study the movement of water, the chemistry of water, aquatic organisms, aquatic ecosystems, the movement of materials in and out of aquatic ecosystems, and the use of water by humans, among other things.

The one distinguishing aspect is that all fields relate to aquatic organisms.
