Transmission Electron Microscopy images and spectroscopy data of insoluble particles extracted from an ice core drilled at Law Dome, East Antarctica. The data is organized into three folders corresponding to mean ice ages of 1795, 1838, and 1930 Common Era. The depth/age scale was constructed by matching dissolved ion chemistry and water stable isotope records to the main DSS ice core record.
Use Cases
- Analyze historical particulate composition based on TEM images and spectroscopy.
- Study climate proxies and atmospheric conditions based on particles from dated ice layers.
- Validate ice core dating models based on particle data from volcanic horizons.
- Train image analysis models for particle classification based on TEM images.
Strengths
- Data is organized by three specific historical time periods (1795, 1838, 1930 CE).
- Includes both TEM images and corresponding EDS/EELS spectra for particles.
- Ice core dating was validated using well-characterized volcanic horizons.
Limitations
- Last updated 2006-01-31 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.
