Chronos 14Carbon-Cycle Facility Taking the Planet's Pulse with Radiocarbon

Based in the University of New South Wales (UNSW), the Chronos 14Carbon-Cycle Facility is a new radiocarbon dating facility based around an Ionplus MICADAS (Mini Carbon Dating System). As part of the Mark Wainwright Analytical Centre, the facility is located in a new purpose-built laboratory dedicated to radiocarbon analysis, with equipment for sample preparation, graphitisation and Accelerator Mass Spectrometry (AMS) dating.

UNSW has exclusive access to ancient sub-fossil and remote subantarctic trees, Antarctic ice, aquifers and sedimentary sequences spanning the last 50,000 years. Capable of making thousands of radiocarbon measurements a year, the MICADAS system is the first in the Southern Hemisphere and will support UNSW researchers in their efforts to spearhead a revolution in understanding the planet’s climate-carbon system.

Ancient air trapped in Antarctic ice

As part of this endeavour, we are collaborating with the Australian Nuclear Science and Technology Organisation (ANSTO), to train a new generation of interdisciplinary researchers needed to meet the environmental challenges of the future

Directors: Professor Chris Turney (Strategy) and Dr Chris Marjo (Operations)

We are supported by a Scientific Advisory Committee comprising staff from UNSW and ANSTO
