We question the effort to date the lower part of a core from the Baltic Sea with a combination of tephra layers and stratigraphical markers. No geochemical data is presented for the two tephra layers, believed to be the Saksunarvatn Ash and Vedde Ash. Furthermore, the age used for one of the stratigraphical markers is erroneous. We present two alternative age models, of which the second gives a plausible sediment accumulation rate but excludes the identification of the Vedde Ash.
