Pollen Data for Williams (2010)
- List of sources of data, but not data, is in a table in the supplementary material
- Most records are from North American Pollen Database (NAPD)
Just browsing through the datasets from this, it looks like a challenge may be that there isn’t much data preceding most of the abrupt shifts - there may not be anything resembling a baseline.
