Tideline

Tideline

A Tideline refers to where two currents in the ocean converge, driftwood, floating seaweed, foam, and other floating debris may accumulate, forming sinuous lines called tidelines (even though they generally have nothing to do with the tide.)

There are four mechanisms that can cause tidelines to form:

1. Where one body of water is sinking beneath or riding over top the surface layer of another body of water (somewhat similar in mechanics to subduction of the earth plates at continental margins). These types of tidelines are often found where rivers enter the ocean.

2. Along the margins of back-eddies.

3. Convergence zones associated with internal gravity waves.

4. Along adjacent cells formed by wind currents.
