Antarctic Ice Core Ion Concentration Measurements from SPRESSO

Ion concentrations from the SPRESSO ice core drilled in Antarctica during the 2002-2003 field season. Measurements were made using ion chromatography and inductively coupled plasma mass spectrometry on co-registered samples. The dataset was produced by the International Trans-Antarctic Science Expedition (ITASE) and archived by AMD_USAPDC.

Use Cases

• Reconstruct historical atmospheric chemistry trends from ion concentration time-series.
• Correlate specific ion species (e.g., sulfate, sodium) with known volcanic or sea salt events.
• Calibrate ice core chronologies by aligning ion concentration peaks with other proxy records.

Strengths

• Data originates from a scientifically drilled ice core as part of the International Trans-Antarctic Science Expedition.
• Multiple analytical techniques (ion chromatography, ICP-MS) were used on co-registered samples.

Limitations

• The exact number of samples, rows, and specific ion species measured are not provided.
• Data is stored in a legacy Microsoft Excel (.xls) format which may require conversion for modern analysis.
