The combined changes between electrodermal resistance and electrodermal potential make up electrodermal activity . "'Galvanic skin resistance "'( GSR ) is an older term that refers to the recorded electrical resistance between two electrodes when a very weak current is steadily passed between them.

The lagoon is connected to the ocean by only two narrow inlets, so the Atmospheric effects are much more important than tides in its circulation; its weak currents generally follow the prevailing winds, and these winds can influence the water level by as much as a meter.
