A continuous 5300-yr Holocene cryptotephrostratigraphic record from northern New Zealand and implications for tephrochronology and volcanic-hazard assessment.
(Hodder Arnold Journals, 2006-02)A continuous 5280 calendar (cal.) yr long cryptotephrostratigraphic record of a peat core from northern New Zealand demonstrates that cryptotephra studies can enhance conventional tephra records by extending the known ... -
Rapid carbon accumulation in a peatland following Late Holocene tephra deposition, New Zealand
(Elsevier, 2020)Contemporary measurements of carbon (C) accumulation rates in peatlands around the world often show the C sink to be stronger on average than at times in the past. Alteration of global nutrient cycles could be contributing ... -
Towards rapid assay of cryptotephra in peat cores: review and evaluation of selected methods
(Elsevier, 2008-02)Peat bogs are highly effective archives for the preservation and detection of cryptotephra but the conventional methods used to detect these hidden, diminutive layers are destructive and can be time consuming. We briefly ... -
Two-step human−environmental impact history for northern New Zealand linked to late-Holocene climate change
(SAGE Publications, 2018)Following resolution of a long-standing debate over the timing of the initial settlement of New Zealand from Polynesia (late 13th century), a prevailing paradigm has developed that invokes rapid transformation of the ...
