From one place

Ocean water can impact local climates because it moves

to another place.

O salt

Odensity

O potential energy

thermal energy

Climates near bodies of water in general are more balanced because water can take in heat from its surroundings and give off heat when it is cold. This is due to its extremely high specific heat. So I think ocean water can impact local climates because of its thermal energy. This is an educated guess though.
