seven tide swings in one afternoon

A tsunami in Maine? Perhaps it was aliens? Maybe a right-wing plot to suppress votes in the ever-pivotal Mid Coast Maine region. Whatever it was, this is just weird:

Sounds like a very small, localized tsunami.

Hmm... wonder if the event that caused this also caused the rogue wave that rolled FreeFall in the recent USCG rescue. The timing is pretty close to right for this to have been the case.

There is a river flowing into Lake Ontario near Trenton that has multiple tides in one day when there is a strong wind blowing in the right direction.There have been 28" tides every three to four hours.Sometimes visiting boats are left hanging from the dock as no one expects it.
I think it is called a seiche.Water levels are pushed up by the wind then gravity forces them back to the lake.

There be mysteries in the deep!!

This sounds very similar to a meteorological gravity wave, or "Rissaga" wave, which I described here at post #875:

Hmmm. Interesting stuff. Here's a vid with more pics of the same Rissaga:

Does one embed a video just like a photo?

Thanks John and all, More stuff I didn't know about!!!

There's a good comment on the linked page that gives several plausible reasons, and I personally sense that a "slope slump" sounds reasonable. See if there are underwater cliffs or steep drop-offs that correspond to the area affected.
