This dataset summarises legacy varve records for 22 sites from the area between 56.8° – 57.1° N, 16.1° – 16.5° E, on Sweden's east coast.
Varve thickness data from legacy annually-laminated sediment archives, along with the co-ordinates of the sediment sites. The varve series have not been correlated, and therefore each should be taken to be on its own timescale.
The legacy data have been collected from Småland in southeastern Sweden by previous researchers since the early 1900’s. The data are not tied to a calendar timescale, but likely represent sedimentation during the Bølling warm period (14.7 – 14.1 thousand years before present).

Data description
The dataset comprises two spreadsheets:
- A summary of the site locations, with site names and other metadata.
- Varve thickness measurements, with one column for each site.
The data are provided in both xlsx and csv file formats.
Comments
The data were digitised from original documents from the Geochronological Museum at Stockholm Univeristy, detailing investigations that took place many decades ago. As such, it is likely that the dataset may contain errors from the original researchers (e.g. miscounting a varve), and possible that errors may have crept in during the digitisation process. Similarly, the site locations, though in decimal degrees here, would originally have been determined from verbose descriptions (e.g. distance and direction from a landmark or settlement) rather than precise co-ordinates.
The varve records were investigated by a number of researchers (names are in the spreadsheet), and were digitised by T. Hang during preparation for Ringberg et al. (2002).
The data have been compiled and deposited in the Bolin Centre Database by R. Avery.
