AI Thread Summary
A recent study suggests that a catastrophic flood may have affected the Black Sea 9,500 years ago, potentially impacting early Neolithic settlements. Researchers from the Woods Hole Oceanographic Institution and Romanian colleagues argue that if such a flood occurred, it was significantly smaller than previously believed. They utilized bivalves to date sediment, as the preservation of bivalve halves indicates minimal disturbance. This method provides insight into the historical events surrounding the Black Sea. The findings challenge earlier theories about the scale of the flood's impact on ancient populations.

ScienceDaily (Jan. 27, 2009) — Did a catastrophic flood of biblical proportions drown the shores of the Black Sea 9,500 years ago, wiping out early Neolithic settlements around its perimeter? A geologist with the Woods Hole Oceanographic Institution (WHOI) and two Romanian colleagues report in the January issue of Quaternary Science Reviews that, if the flood occurred at all, it was much smaller than previously proposed by other

They use bivalves to date sediment, the material that holds the two sides of bivalve together decays easily, so if the two halves are found together it is a good indication they have not been redistributed, cool idea.

This is probably how it happened.

Thread 'The Secrets of Prof. Verschure's Rosetta Stones'

(Edit: since the thread title was changed, this first sentence is too cryptic: the original title referred to a Tool song....) Besides being a favorite song by a favorite band, the thread title is a straightforward play on words. This summer, as a present to myself for being promoted, I purchased a collection of thin sections that I believe comprise the research materials of Prof. Rob Verschure, who at the time was faculty in the Geological Institute in Amsterdam.

Thread 'Landslide, tsunami, seiche in Tracy Arm fjord, Alaska - 10 August 2025'

On August 10, 2025, there was a massive landslide on the eastern side of Tracy Arm fjord. Although some sources mention 1000 ft tsunami, that height represents the run-up on the sides of the fjord. Technically it was a seiche.
