Sea Caves

[paul]

I think i must humbly disagree.
If part of a cave is tidal, then at least that part of the cave is a sea cave :agree:

Sea level rises with high tide.
River Wye level rises as its outlet to the sea has risen.
Otter Hole's resurgence is covered by rising river.
Water backs up in cave forming sump.

The cave was formed in the ususal manner of limestone caves but has a sump affected by the state of the tide in the area where a nearby river debouches.

Cave not formed by action of the sea - not a sea cave.

Definitely.  It's not a sea cave, but a cave formed by the usual karst processes which was subsequently partially invaded by the sea.  Confused?  Yes?  No?
