Erm ... if in such a scenario sea-level drops 100m below current shoreline at low tide, wouldn't it rise nearly 100m at high tide - assuming the total volume of the ocean being the same ? In which case the dry-land coastline would be much further inland.

Wouldn't the tides go up and down? map seems to show down only

I understand it as both, as the tides would occupy the yellow zones when up

But the green zones are current shorelines.

Their answer is "idk lol".

Which means they didn't consider it. Of course lower low tides also mean higher high tides, the water has to go somewhere.

Fun map! The spelling of the Danish islands is weird though, looks like the German names?
