DE08 Ice Core Report: Temperature, Age, and Density at Depth, 1987

AU_AADC provides a report on the drilling of a 234-meter deep ice core at site DE08, 16km east of the summit of Law Dome, Antarctica, during the 1987/88 season. The report includes expedition details, drilling methods, and data on temperature, ice age, and ice density at various depths. It was last updated in the NASA Earth Data system on February 26, 1998.

Use Cases

• Reconstructing historical climate trends based on temperature records at depth.
• Modeling ice sheet accumulation and flow using the age of ice at depth.
• Analyzing firn densification processes based on density of ice at depth.
• Studying expedition logistics and ice core drilling methods in Antarctica.

Strengths

• Provides specific physical measurements from a 234-meter deep, 195mm diameter ice core.
• Includes multiple data types: temperature records, ice age, and ice density.
• Data is tied to a specific, documented location (DE08, Law Dome) and season (1987/88).

Limitations

• Last updated 1998-02-26 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
