shoal continues to migrate landward into the bay. Beginning in 1976, Nauset Spit
gained sand and migrated more to the south, narrowing the inlet throat. The spit
has formed a series of three recurves since 1998. The flood shoal continues to
expand northward and westward, causing Tern Island to migrate to the north also.
The west channel between the island and flood shoal has closed as the spillover
lobe has become the dominate feature. This ebb-orientated feature is trying to
break through the flood shoal and re-establish the former west channel.
