Optical Logging Data for Dust and Microbes in Antarctic Borehole

NASA Earthdata hosts optical borehole logging measurements from the Siple Dome A site in Antarctica. The data set contains high-resolution logs of dust and microbial particles detected in glacial ice, with information on depth and optical signal. Data were collected by AMD_USAPDC and last updated in February 2002.

Use Cases

• Analyze dust concentration trends with depth using optical signal measurements.
• Correlate microbial presence signals with specific depth intervals in the borehole.
• Study optical properties of particles detected several meters from the borehole wall.
• Model particulate distribution in glacial ice using depth and optical signal columns.

Strengths

• High-resolution optical logs from a specialized borehole logger.
• Data captures particles out to several meters from the borehole.
• Measurements from a specific Antarctic site (Siple Dome A).

Limitations

• Data set size, row count, and file formats are unknown.
• Data is from a single borehole, limiting geographic scope.
• Last update was in 2002, indicating potential staleness.
