A low resource subglacial bedrock sampler: The percussive rapid access isotope drill (P-RAID)
The paleoclimate community has an interest in distributed subglacial bedrock sampling but, while capable drill systems do exist, they are often incompatible with Twin Otter logistics. To address this issue, a design built on the existing low footprint ice-sampler, the Rapid Access Isotope Drill (RAI...
