Multi-centennial tree-ring record of ENSO- related activity in New Zealand. Nature Climate Change 2:172-176. NOTES: BIRK (16 Maritime Terrace, Birkenhead, Auckland). A late 19th century villa where the veranda was being replaced. Samples obtained from veranda timbers for contribution to late-Holocene kauri chronology. Data covers two time periods. Because of the large size of kauri trees and industrialized production (a) series represent only part of the growth span for the tree; (b) there are probable same-tree material in the set. Raw ring width measurements only (0.01mm). No CRN file. COFECHA output: Chronology file name : NEWZ105.CRN Measurement file name : NEWZ105.RWL Date checked : 10SEP12 Checked by : B.
