Hi Eric, Jen and others,

A student of mine Chris Wurster has just the water and carbonate data
you're looking for from two different sized lakes (one is very small)
located in PA and NY. He also sampled mollusks at high resolution
from the same lakes. He compared the data to meteorological data from
local weather stations.

It is set for publication soon in paleolimnology (maybe next month?).
He should be back from Reno soon. I'll pass the word along to him. If
you or anyone else would like to contact him about the data he can be
reached at [log in to unmask]

Cheers,
Bill
