Isotope analyser with delta-17-O capability to examine water fluxes: This project aims to investigate a range of processes, including quantifying evaporative losses, moisture recycling, groundwater-surface water interactions, and records of past climate in ice cores using novel capabilities for continuous measurement of triple oxygen isotopes (16-O, 17-O, 18-O) in water vapour. Enhanced understanding of water cycles is critical for understanding the discrete changes occurring in water regimes under changing climates and land use to efficiently manage our limited freshwater resources. The instrumentation is intended to put Australia at the forefront of new and emerging research in d17O analysis of water, an area that has potential to greatly improve our understanding of the water cycle within arid climates including Antarctica.

具有δ-17-O能力的同位素分析仪，用于检查水通量：该项目旨在调查一系列过程，包括量化蒸发损失、水分再循环、地下水-地表水相互作用，以及利用连续测量水蒸气中三重氧同位素（16-O、17-O、18-O）的新能力记录冰芯中的过去气候。加强对水循环的了解对于了解在不断变化的气候和土地利用下水系统发生的离散变化至关重要，以有效管理我们有限的淡水资源。该仪器旨在使澳大利亚处于d17 O水分析新研究的最前沿，这一领域有可能大大提高我们对包括南极洲在内的干旱气候中水循环的理解。
