Petmyra (PISY-ref)

Petmyra (PISY-ref) is a Ring Width Measurements only collection of PISY-samples collected at the Petmyra, a Spagnum peat bogg a few kilometers south of Björbo. It was created mainly in order to to date the well preserved wooden remains from the peat harvesting in the early 20'th century which turned out not to be datable towards standard references like swed305.
