South Pole Ice Core Laser Dust Logging Borehole Data

Laser dust logging data from a South Pole ice core borehole provides sub-centimeter scale paleoclimate features. The project, supported by AMD_USAPDC, deployed an oriented logger with a magnetic compass to investigate impurity location and ice sheet properties. Data and metadata were made available through repositories like the National Snow and Ice Data Center, with project activity noted in 2019.

Use Cases

• Determine depth-age relationships using oriented borehole log data and magnetic compass readings.
• Map South Pole stratigraphy in 3D by analyzing optical scattering measurements and particulate horizon data.
• Investigate correlations between insoluble particulate anisotropy, ice crystal fabric, and flow using sub-centimeter laser measurements.
• Develop a record of South Pole surface roughness as a proxy for paleowind from in-situ borehole logging data.
• Aid searches for the oldest ice in Antarctica by synchronizing records and detecting accumulation anomalies from dust logger data.

Strengths

• Data captures paleoclimate features at a sub-centimeter depth resolution.
• Project includes field work in Antarctica for direct, in-situ borehole measurements.
• Data is intended for availability through established repositories like the National Snow and Ice Data Center.

Limitations

• Specific data volume (row count, file size) and column details are unknown.
• The dataset's temporal coverage and exact geographic coordinates within the South Pole are unspecified.
• Data recency is unclear as the last noted update was in March 2019.
