- Abstract
- <h4>Rationale</h4>In this study, we tested stable hydrogen isotope ratios of wood lignin methoxyl groups (δ<sup>2</sup> H<sub>methoxyl</sub> values) as a palaeoclimate proxy in dendrochronology. This is a quite new method in the field of dendrochronology and the sample preparation is much simpler than the methods used before to measure δ<sup>2</sup> H values from wood.<h4>Methods</h4>We measured δ<sup>2</sup> H<sub>methoxyl</sub> values in high elevation larch trees (Larix decidua Mill.) from Simplon Valley (southern Switzerland). Thirty-seven larch trees were sampled and five individuals analysed for their δ<sup>2</sup> H<sub>methoxyl</sub> values at annual (1971-2009) and pentadal resolution (1746-2009). The δ<sup>2</sup> H<sub>methoxyl</sub> values were measured as CH<sub>3</sub> I released upon treatment of the dried wood samples with hydroiodic acid. 10-90 μL from the head-space were injected into the gas chromatography/high-temperature conversion/isotope ratio mass spectrometry (GC/HTC-IRMS) system.<h4>Results</h4>Testing the climate response of the δ<sup>2</sup> H<sub>methoxyl</sub> values, the annually resolved series show a positive correlation of r = 0.60 with June/July precipitation. The pentadally resolved δ<sup>2</sup> H<sub>methoxyl</sub> series do not show any significant correlation to climate parameters.<h4>Conclusions</h4>Increased precipitation during June and July, which are on average warm and relatively dry months, results in higher δ<sup>2</sup> H values of the xylem water and, therefore, higher δ<sup>2</sup> H values in the lignin methoxyl groups. Therefore, we suggest that δ<sup>2</sup> H<sub>methoxyl</sub> values of high elevation larch trees might serve as a summer precipitation proxy.

- Abstract
- RATIONALE: In this study, we tested stable hydrogen isotope ratios of wood lignin methoxyl groups (δ2 Hmethoxyl values) as a palaeoclimate proxy in dendrochronology. This is a quite new method in the field of dendrochronology and the sample preparation is much simpler than the methods used before to measure δ2 H values from wood. METHODS: We measured δ2 Hmethoxyl values in high elevation larch trees (Larix decidua Mill.) from Simplon Valley (southern Switzerland). Thirty-seven larch trees were sampled and five individuals analysed for their δ2 Hmethoxyl values at annual (1971-2009) and pentadal resolution (1746-2009). The δ2 Hmethoxyl values were measured as CH3 I released upon treatment of the dried wood samples with hydroiodic acid. 10-90 μL from the head-space were injected into the gas chromatography/high-temperature conversion/isotope ratio mass spectrometry (GC/HTC-IRMS) system. RESULTS: Testing the climate response of the δ2 Hmethoxyl values, the annually resolved series show a positive correlation of r = 0.60 with June/July precipitation. The pentadally resolved δ2 Hmethoxyl series do not show any significant correlation to climate parameters. CONCLUSIONS: Increased precipitation during June and July, which are on average warm and relatively dry months, results in higher δ2 H values of the xylem water and, therefore, higher δ2 H values in the lignin methoxyl groups. Therefore, we suggest that δ2 Hmethoxyl values of high elevation larch trees might serve as a summer precipitation proxy.
