DO-21 Rapid Warming Event: Ultra-High Resolution LA-ICP-MS Ice Core Data

NASA Earthdata hosts LA-ICP-MS results from the GISP2 ice core archive, focusing on the rapid climate warming of Dansgaard-Oeschger Event 21. The dataset was contributed by the organization AMD_USAPDC and was last updated in April 2015. It provides ultra-high resolution geochemical measurements from a key paleoclimate event.

Use Cases

• Analyze rapid climate change signatures based on ultra-high resolution geochemical measurements.
• Model paleoclimate dynamics based on data from the Dansgaard-Oeschger Event 21.
• Calibrate climate proxies based on Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) results.
• Study ice core geochemistry based on data from the GISP2 ice core archive.

Strengths

• Data focuses on a specific, well-known rapid climate event (Dansgaard-Oeschger Event 21).
• Measurements are described as ultra-high resolution, suggesting fine temporal detail.
• Data originates from the authoritative GISP2 ice core archive.

Limitations

• Last updated 2015-04-24 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.
