It's incredible that Mindspawn is still saying this stuff about Lake Suigetsu.

I need your evidence that freshwater diatoms definitely CANNOT be affected by the rising salt water table in a lake next to the sea.
No one has said this isn't possible. What's been said is that the floor of Lake Suigetsu is 20 to 30 meters above sea level, way above the water table, too far above to be affected by it. Plus Mindspawn even quoted one of his own sources saying that tides do not affect the salinity levels of nearby water tables, so his spring tides cannot have the effect he claimed. And the core samples were taken in the center of Lake Suigetsu, miles from the ocean.
Even in places where spring tides might have an effect on varve layers (perhaps by spring tides spilling over into a nearby lake, since as mentioned before tides do not affect the salinity of nearby water tables), spring tides occur around 26 times a year, not 12 which is what Mindspawn needs.
In other words, not only has Mindspawn presented no evidence that spring tides cause varve layers in Lake Suigetsu, all the evidence we have says it isn't possible, and his own claims don't even produce the result he needs.
