Siple Dome Ice Core LA-ICP-MS Data for Dansgaard-Oeschger Event 21

LA-ICP-MS results from three Siple Dome A ice core archives capture the rapid climate warming of Dansgaard-Oeschger Event 21. The dataset provides elemental composition data for paleoclimate reconstruction. It was produced by the AMD_USAPDC organization and last updated in April 2015.

Use Cases

• Reconstruct past atmospheric dust loading by analyzing trace element concentrations like aluminum or calcium.
• Identify volcanic eruption signals within the ice core record using sulfur and other volcanic tracer elements.
• Calibrate climate models by correlating LA-ICP-MS elemental ratios with known temperature proxies from Dansgaard-Oeschger Event 21.
• Study changes in oceanic productivity or sea ice extent through variations in marine-sourced elements like sodium or magnesium.

Strengths

• Focuses on a specific, well-defined rapid climate event (Dansgaard-Oeschger Event 21).
• Data generated using Laser Ablation Inductively Coupled Plasma Mass Spectrometry, a high-resolution analytical technique.
• Covers three distinct ice core archives from the Siple Dome A site.

Limitations

• Dataset size, row count, and specific column names are unknown, limiting assessment of scope.
• Data is from 2015 and may not reflect the most recent analytical standards or interpretations.
• Geographic scope is limited to a single ice core site (Siple Dome, Antarctica).
