In this new study, Dr. Warr and collaborators from the University of Toronto revisit the way that people calculate production rates of 4He, 40Ar, H2 and SO4 in  the subsurface. By applying a new Monte Carlo approach natural variability can now be effectively factored in to generate represntative production rates of the economically and biologically important crustal  components.

In our latest paper we demonstrate how  short-lived radiotracers (3H, 14C, 36Cl, 39Ar, and 81K) can be produced in subsurface fluids and how aqueous and solid rock geochemistry can serve as key controls on the baseline fluid residence time calculated from these tracers.

In our latest paper we demonstrate how deep subsurface settings can simultaneously preserve fluids over billion-year timescales and yet also effectively act as power sources generating helium resources and fueling deep biospheres on Earth and beyond. Here's a press release and an interview with Oliver for more information .

We are happy to announce that Dr. Warr has now been appointed as a Tenure-track Assistant professor in the Department of Earth and Environmental Science Unversity of Ottawa with a start date of October 1st 2022!
