University of Minnesota
Supporting Stations: McMurdo Station
Research Locations: Siple Dome / West Antarctic Ice Sheet (WAIS) Divide
The research team has two primary goals for this project: (1) To introduce fiber-optic based tools that circumvent the need to have power supplies, laser sources, optics, detectors, and electronic processing capabilities mounted on the unit that descends into the borehole, thus keeping most of the system weight, size, and complexity on the surface; (2) To add some level of fabric measurement capability to borehole logging tools using polarized light backscattered from the borehole ice and analyzed using polarization-sensitive optics.
Field Season Overview:
Researchers will travel to WAIS Divide to test borehole logging instruments. They will have one fiber-based instrument whose purpose is to compare the quality of data taken to the optical dust logger which another researcher will deploy in the main WAIS Divide borehole. They will also have another optical instrument that will attempt to measure average fabric and grain size. Since the project is one of technology development, the most important work can be done in the secondary borehole holes at WAIS rather than the primary, but if there is open space in the schedule, they may also test their fiber tool in the main hole.
