The Stampfli 2-Inch Drill is a lightweight electromechanical drill that takes a 57 mm (2-inch) diameter core. The drill was purchased from Dieter Stampfli in Switzerland to meet requests from the community for a lightweight, PI-operable system capable of collecting core down to 100-meters depth. The drill is configured with a winch and cable for 100 meters depth and is powered by batteries, which can be charged by either a small generator or a set of solar panels. The drill is very field portable. The drill system fits inside one helicopter or twin otter, and is packed in pieces that can be lifted by one person and transported up a mountain solely by a human on foot or skis. A lightweight Tentipi Safir tent for use with the system is also available.
The system was deployed for an NSF-funded field project in summer 2018 in the Yukon Territory, Canada, where it was operated by the science team to collect one firn core to 10 m depth and another to 20 m depth. In 2019, a science team successfully collected a 50 m core from Mt. Hunter in Denali National Park, Alaska.
