The Sediment Laden Lake Ice Drill (SLLID) is a 28 kW hot water drill useful for creating holes with very little initial water, for freeing instrument cables from the ice, and for accessing equipment deployed beneath the ice. The drill is effective at drilling through sediment laden ice and allows safe servicing of science instruments deployed in the lakes and ocean.
The SLLID is designed to achieve a drilling speed of less than 30 minutes for a 5-inch hole through a 6 meter ice cover. Drill components are small, lightweight and are able to be lifted by a maximum of two people. The drill has stand-alone capability for operation at small field camps at remote sites with no heavy equipment and is intended to be operated by the science team. Components that allow for clean access drilling were also incorporated in the design. Fabrication, final assembly and in-house testing of the drill were completed in fall 2017. The system was deployed for its first field project in the Dry Valleys of Antarctica during the 2018-2019 field season.
