Dendrochronology (Gretel Boswijk)


a) Sample identifier (Dendro-Lab Key-code): HAR010a
b) Sample certainly derives from a single tree (Y/N): Y

	Rings 159-169 inclusive (1180-1170 cal BP inclusive / AD 770-780 inclusive) and	rings 379-389 (960-950 cal BP inclusive / AD 990-1000 inclusive) were dated.

c) Site: Harding’s Farm, Hilliam Road, near Dargaville, Northland, New Zealand (173°48′E, 35°55′S)
d) Object type: fallen tree
e) Preservation: waterlogged in swamp
f) Sample type (e.g. core or slice): slice
g) Species: Agathis australis
h) No of rings: 517
i) Pith (Y/N): < 5 to pith
j) Waney edge: no
k) Bark (Y/N): no
l) Sapwood (Y/N): no
m) Methodology used for dating:
Full details of methodology used for cross-matching and dating are provided in:

Boswijk, G, 2005 Tree-ring analysis of sub-fossil kauri (Agathis australis) from the Harding’s Farm, Hilliam Road, near Daraville, Northland, New Zealand Tree-Ring Site Reports, 16

n) Dated individually (Y/N) : N
see above, part of site master Harding1 which was dated against two sub-fossil kauri chronologies (Furniss1 and Yakas1). The 0 value rings for AD 921 and AD 1101 represent rings missing from this radius. The position of missing rings is based on visual crossmatching of intra-tree series.
p) Raw ring width series attached
q) Remainder of sample is stored in which archive?
