Law Dome Atmospheric Gas Records from Ice Cores

1987 to 1993 ice core records provide CO2 and CH4 concentration data from three cores drilled at Law Dome, East Antarctica. The dataset includes measurements from cores reaching a depth of 1199.6 meters. It was produced by the organization AMD_USAPDC.

Use Cases

• Analyze temporal trends in CO2 and CH4 concentrations from the 1987-1993 ice core records.
• Correlate gas concentration data from three distinct ice cores to assess measurement consistency.
• Use the depth profile data (up to 1199.6 meters) to establish a chronology for the atmospheric gas records.
• Study the spatial variability of atmospheric gases at Law Dome, a 200 km diameter ice sheet.

Strengths

• Data derived from three distinct ice cores, providing multiple measurement sources.
• Covers a specific drilling period from 1987 to 1993 with cores reaching 1199.6 meters depth.
• Focuses on two key atmospheric greenhouse gases: CO2 and CH4.

Limitations

• The temporal coverage of the core drilling (1987-1993) is limited to a short modern period, not long-term history.
• Geographic scope is restricted to a single location: Law Dome, East Antarctica.
• Sample size is limited to three ice cores.
