The BOREAS TE-22 team collected complete tree cores at several sites in the SSA and NSA in order to perform historical growth studies and relate the information to their modeling activities. The cores were collected during the summer of 1994 in the Northern and Southern Study Areas. A sample of the file types resulting from the analysis of the tree cores are provided.
