Speleothems Isotopes 2015 CD4 (ARCA)

Arctic Present Climate Change and Past Extreme Events (ARCA)

CD4 core was micromilled at 200 μm increments using a micro-milling method (Drysdale et al., 2012). The stable isotope composition of the powders was measured on CO2 gas released by reaction with 105% H3PO4 at 70°C, which was measured using a mass spectrometer. Isotopic results are reported using the conventional δ-notation in per mille (‰), with reference to the Vienna Pee Dee Belemnite (V -PDB) standard.

Instrument : MC-ICPMS, Nu-Instruments Plasma, Finnigan GasBench

Parameter : Th**230/U**238 and U**234/U**238 activity ratios, (δ**13)C and (δ**18)O

Purpose

ARCA aims to develop a conceptual model on the mechanism(s) behind the release of large volumes of cold and fresh water from melting of ice caps, investigating this complex system from both paleoclimatic and modern air-sea-ice interaction process point of view.
