Description
This presentation is a concise collage of technical innovations and their usefulness in the latest field seasons of the Beyond Epica Oldest Ice drilling project. Improvements were made with the following newly developed equipment:
• Replacement drill-head for filtering of the borehole.
• Fine slush filtering with the drills shaft within the chip chamber.
• Daily maintenance routines and de-icing of the drills shaft and pump.
• Glove box for drying and warming of drillers gloves.
• Jig for sharpening of drillhead cutters. (please see also the presentation “Drillhead Configurations and Maintenance in the BEOI's Deep Ice Core Drilling Project”
• Temperature logging of the bore hole.
• 3D printing in the field.
1. custom made medical finger orthosis
2. Light-Diffusor for illumination of ice-core crystal observation.
3. Clamps for aligning a tape ruler on an ice-core for logging
4. Clamps for marking the ice-core for cutting.
5. Improvements to the support of ice-cores for cutting with a rotational saw.
6. Ice-core scraper (please see also the additional talk)
7. Team building with BEOI cookie-cutters.
• Devices for cutting ice-cores without the material losses of a saw kerf.
• Vial holders for transport of ice-samples and handling of liquid in the lab.
• Fine filtering of recycled drill liquid.
• Lessons learned with recycling drill liquid by ice-melting. Challenges with plastic material and leaking hoses in contact with warm drill liquid and Hose handling.
• Light-tight covers for handling ice-cores in the dark.
• Scooper for collecting firn samples.
• Safe and efficient work environment: Improved stairs and steps, floor gratings in front of doors, custom build shelves, repair of shovels.
