“…The drilling head uses three sets of cutting teeth at an angle of 40 • (Figure 3) that were constructed of hardened stainless steel and coated in PVD to increase hardness and abrasion resistance. Cutting teeth were staggered to reduce icing (Figure 3; Talalay, 2016a). The drill (Figure 2) can be installed and removed easily and permits the use of an extraction tool to remove the ice sample (Figure 4).…”

The ecological impacts of meltwater produced by icebergs and sea ice in the waters around Greenland are poorly understood, due in part to limited observations. Current field sampling methods are resource and labor-intensive, and not without significant risk. We developed a small, unoccupied, and robotic platform to retrieve ice samples, while simultaneously eliminating safety risks to scientists and their support infrastructure. The IceDrone consists of a modified commercial hexcopter that retrieves ice samples. We describe the design requirements, construction, and testing of the IceDrone. IceDrone's capabilities were validated in the laboratory and during a field test in January 2019 near Nuuk (southwest Greenland). IceDrone retrieved samples in hard and dry glacial ice in harsh winter conditions. The field test led to modifications in the drilling head design and drilling process that enable it to retrieve samples in thin sea ice. All design files and software are provided in an attempt to rapidly enhance our collective understanding of ice-ocean interactions while improving the safety and productivity of field sampling campaigns.

“…Similarly, drilling is only possible on ice that is free of any appreciable snow and/or firn layer. While this is a limitation, drilling through firn remains a general challenge for the ice sampling community (Talalay, 2016a).…”
