11 May 15 - International Symposium on Isotope Hydrology: Revisiting Foundations and Exploring Frontiers
 The International Atomic Energy Agency (IAEA) has convened quadrennial symposia on isotope hydrology since 1963. For more than 50 years, these IAEA symposia have provided a unique opportunity to review the state-of-the-science, practical applications, and research trends and needs in isotope hydrology, leading to its recognition as a discipline in its own right within the science of hydrology. Isotope hydrology contributes to a better understanding of the water cycle and has applications in water resources assessment and management, the study of past and future changes in the Earth’s climate as well as of climate impacts on the water cycle, and in forensic areas such as ecological, wildlife and food source traceability.

This is the 14th symposium in the series and it will be held at the IAEA’s Headquarters in Vienna, Austria, from 11 to 15 May 2015. The symposium will aim to facilitate the exchange of information and knowledge among water and environment professionals from developed and developing countries.

16 Sep 13 - LGR's Triple Isotopic Water Analyzer measures accurate 17O-excess values in real time and without any sample preparation

Peer-reviewed publication reports:

LGR's Triple Isotopic Water Analyzer measures accurate 17O-excess values in real time and without any sample preparation.

Stable isotopes of water have long been used to improve understanding of the hydrological cycle, catchment hydrology, and polar climate. Recently, there has been increasing interest in measurement and use of the less-abundant 17O isotope in addition to 2H and 18O. Off-axis integrated cavity output spectroscopy (OA-ICOS) is demonstrated for accurate and precise measurements δ18O, δ17O, and 17O-excess in liquid water. OA-ICOS involves no sample conversion and has a small footprint, allowing measurements to be made by researchers collecting the samples.
