Drilling Within the Critical Zone

Hydrological Processes, Volume 40, Issue 3, March 2026.
This review synthesises 30 years of critical zone drilling methodologies for studying subsurface weathering, water storage, and biogeochemical processes. We evaluate drilling techniques, sampling strategies, downhole logging, and long‐term monitoring approaches while addressing contamination control and core preservation challenges.
