Borehole Temperature Measurements from Law Dome Ice Core

BHQ ice core borehole temperature data was collected in 1977 at Law Dome, Antarctica. The Australian Antarctic Division (AU_AADC) archived the original hard copy records. This dataset captures a single year of subsurface temperature readings from a specific drilling site.

Use Cases

• Analyzing temperature_depth profiles from the BHQ borehole for thermal modeling of the ice sheet.
• Correlating 1977 borehole temperature readings with other Law Dome climate proxy records.
• Calibrating ice core dating models using recorded drill time and temperature data points.
• Studying subsurface heat flow and geothermal gradients at the specific BHQ drilling site.

Strengths

• Data originates from a documented 1977 Antarctic drilling campaign.
• Records are archived by the authoritative Australian Antarctic Division.

Limitations

• The dataset is over 45 years old and may not reflect current conditions.
• Specific data volume (rows, columns) and granularity are unknown.
• Data is from a single location (Law Dome BHQ site) and year, limiting spatial and temporal scope.
