It appears to be a small island that has not fully separated from the mainland. Bentley Lacrosse Division, In this zone, the waves touch the seabed and so the material is usually disturbed, sometimes being pushed up as offshore bars, when the offshore gradient is very shallow. This drift is often influenced by the wind direction. Sometimes a spit extends far enough out to sea to join a coastal island to the mainland. .entry-content a{ Tomobolos are linear ridges (or bar) of sand and shingle connecting an offshore island to the coastline of the mainland.
