Karina Meredith

Profile

Role at ANSTO

 

Karina is a research scientist in the Isotopes for Water project. She is working in the fields of hydrochemistry, hydrogeology and isotope hydrology on a variety of projects located throughout Australia. Her research interests lie in applying a variety of stable, radiogenic and cosmogenic isotopic tracers to investigate groundwater resource sustainability and the suitability of aquifer systems as potential low resolution climate archives. 

 

Expertise

 

Hydrogeochemistry, hydrogeology, radiocarbon, groundwater, hydrogeochemical modelling, isotopes.
