Hellstrom, J., M. McCulloch, and J. Stone. 1998.
A detailed 31,000-year record of climate and vegetation change,
from the isotope geochemistry of two New Zealand speleothems.
Quaternary Research, Vol. 50, pp. 167-178.
ARTICLE NO. QR981991
Uranium-series dating and stable isotope analyses of two speleothems
from northwest Nelson, New Zealand, record changes in regional climate
and local forest extent over the past 31,000 years. Oxygen isotope
variation in these speleothems primarily represents changes in the
meteoric waters falling above the caves, possibly responding to
latitudinal changes in the position of the Subtropical Front in the
Tasman Sea. Seven positive excursions can be identified in the oxygen
isotope record, which coincide with periods of glacier advance,
known to be sensitive to northward movement of the Subtropical Front.
Four glacier advances occurred during oxygen isotope stage 2, with the
most extreme glacial conditions centered on 19,000 cal yr B.P.
An excursion in the oxygen isotope record from 13,800 to 11,700
cal yr B.P. provides support for a previously identified New Zealand
glacier advance at the time of the Younger Dryas Stade, but suggests
it began slightly before the Younger Dryas as recorded in Greenland
ice cores. Carbon isotope variations in the speleothems record changes
in forest productivity, closely matching existing paleovegetation
records. On the basis of vegetation changes, stage 2 glacial climate
conditions terminated abruptly in central New Zealand, from 15,700
to 14,200 cal yr B.P. Evidence of continuous speleothem growth at one
site suggests that depression of the local treeline was limited to
600-700 m below its present altitude, throughout the last 31,000 years.
STUDY NOTES: Continuous high-resolution stable isotope records from caves
in New Zealand over the last 31,000 yr. Mt. Arthur (1795 m)
is located northwestern corner of New Zealand's South Island,
underlain by many known cave systems, the two largest and
deepest being Exhaleair and Nettlebed Caves used for this study.
A 50-mm-diameter core sample was recovered from each site
by drilling into gently sloping flowstones (massive sheet
speleothems which form on cave walls and floors).
Core MD3 was dated at nine points, and Core ED1 was dated at
three points, using the mass-spectrometric 238U-234U-230Th method.
