Per the Long Range Science Plan, a mid-range drill (700 m) is desired for use in remote areas such as mountain glaciers in the Arctic.
Science Requirements were completed in March 2018 for a drill originally referred to as the Foro 700 Drill, as the idea was to utilize the current sonde design of the Foro 1650 and the Foro 400. IDP subsequently completed a Conceptual Overview of the system, and a conceptual design review was held in August 2019 with members of the science community. Following the review and in response to reviewer questions, IDP completed an analysis of the quantity of drill fluid and ice core boxes needed. IDP also evaluated designing around a smaller diameter sonde such as that of the Badger-Eclipse Drill. Following further consultation with the science community on reducing the logistical burden of a new design, the IDP Science Requirements were updated based on an even smaller-diameter core than the Foro Drills or the Badger-Eclipse Drills. IDP subsequently updated the Conceptual Overview for the drill, now referred to as the 700 Drill, and held another review with science community representatives in January 2021. Following positive feedback from that review, IDP sought and gained NSF approval in March 2021 to move forward with the Detailed Design of the 700 Drill. The Detailed Design was completed and reviewed in November 2021, and NSF approval to move forward with fabrication of the drill was granted in February 2022. The final IDP Science Requirements for the 700 Drill, finalized in January 2021, identify a core diameter of 70 mm, with the drill to be designed in a way that a possible future core barrel with 64 mm diameter would be a minor adaptation.
Design drawings have largely been completed and fabrication and assembly of the drill are well underway. The system is expected to be ready in spring 2024 and may be field tested by IDP at that time, pending NSF support and approval.
