Barometric pressure, tides, winds, waves, they all play a role in the ebb and flow of the ocean.
A new study finds that that river outflow could play a role in sea level change as well.
By examining decades' worth of river level and tidal data from gauges installed throughout the eastern United States. and combining that data with information on water density, salinity, and the Earth's rotation, they created a mathematical model that describes the link between river discharge and sea level on an annual basis.
