low tide line
Ocean's retreating edge
The low tide line is the boundary on a shore marking where the water reaches at its lowest ebb.
It shifts with tidal cycles, moving seaward during extreme low tides.
The area between the high tide line and low tide line—the intertidal zone—has legal significance for property rights, fishing access, and coastal jurisdiction: The public has access to beaches below the low tide line.
