Optical Logging for Dust and Microbes in Boreholes in Glacial Ice
Entry ID: NSIDC-0403

[ Update this Record ]

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).
