Optical Logging for Dust and Microbes in Boreholes in Glacial Ice Data DOI: https://doi.org/10.7265/N59P2ZKB Cite as Bay, R. (2009) "Optical Logging for Dust and Microbes in Boreholes in Glacial Ice" U.S. Antarctic Program (USAP) Data Center. doi: https://doi.org/10.7265/N59P2ZKB. AMD - DIF Record(s) NSIDC-0403_1 Abstract This data set contains high-resolution logs of dust and microbes measured at the Siple Dome A borehole in Antarctica. The data were obtained using a newly developed optical borehole logger, which fits into a fluid-filled borehole in glacial ice. It can detect dust and microbes in ice out to several meters from the borehole, and measure optical properties of those particles. The data set contains information on depth and optical signal. Data are available via FTP in data file format (.dat).
