Lake Taupo, in the North Island of New Zealand, is a globally significant caldera of a supervolcano that formed following a massive eruption more than 20, years ago. Over the past two decades, the method has been refined greatly by combining it with dendrochronology, the study of the environmental effects on the width of tree rings through time. Radiocarbon dating of tree ring records has allowed scientists to construct a reliable record of the concentration of carbon in the atmosphere through time.

In principle, this composite record allows eruptions to be dated by matching the wiggly trace of carbon in a tree killed by an eruption to the wiggly trace of atmospheric carbon from the reference curve "wiggle-match" dating. Scientists presently use wiggle-match dating as the method of choice for eruption dating, but the technique is not valid if carbon dioxide gas from the volcano is affecting a tree's version of the wiggle.

The effect of volcanic carbon on eruption ages Our study re-analysed the large series of radiocarbon dates for the Taupo eruption and found that the oldest dates were closest to the volcano vent. The dates were progressively younger the farther away they were.

This unusual geographic pattern has been documented very close i. Two wiggle match agestaken from the same forest, located about 30km from the caldera lake, were among the oldest dates from the series of dates.

This conceptual image shows how gas from the triggering event, decades before the eruption, works its way into the groundwater system and is eventually incorporated in the wood of the trees that we date. Provided by authors, CC BY-ND This enlarged influence of the volcano can be explained by the influence of groundwater beneath the lake and its surroundings.

Radiocarbon dating

The Taupo wiggle-match tree grew in a dense forest in a swampy valley where volcanic carbon dioxide was seeping out of the ground and was incorporated in the trees.

The ratio of carbon to carbon the two stable isotopes of carbon in the modern water of Lake Taupo and the Waikato River tells us that volcanic carbon dioxide is getting into the groundwater from an underlying magma body. Can large eruptions be forecast over decades? Our study shows that a large and increasing volume of carbon dioxide gas containing these stable isotopes was emitted from deep below the prehistoric Taupo volcano.

It was then redistributed by the region's huge groundwater system, ultimately becoming incorporated into the wood of the dated trees. The increase was sufficiently large over several decades to dramatically alter the ratios of different carbon isotopes in the tree wood.
