5 & 12 August 2025 – Auckland & Christchurch
Dr. Grant Ferguson from the University of Saskatchewan, Canada presented “Deep Groundwater and Deep Time” as part of the 2025 NGWA Darcy Lecture Series.
The lectures were held at BECA Auckland (5 August) and University of Canterbury (12 August) with good turnout at both venues.
Overview
Dr. Ferguson’s presentation explored the vast volumes of deep groundwater systems that rival ice sheets in scale. He discussed how these systems, while contributing minimally to streamflow, are increasingly important for carbon sequestration, waste disposal, and understanding Earth’s subsurface biosphere. The lecture highlighted the unique challenges of studying deep groundwater, including complex flow processes driven by density variations and geological forces operating over geological timescales.
