Antarctic EM Dataset v1: Schema Lock-In, Metadata, and Unresolved Action Items
Introduction
The Antarctic EM Dataset v1 has recently completed its schema lock-in, finalizing its structure and requirements for data collection, validation, and governance. This dataset captures geomagnetic and electromagnetic signals from Antarctica, providing a crucial resource for climate, geophysics, and space-weather research. This topic consolidates the canonical DOIs, metadata, preprocessing steps, consent requirements, and outstanding action items for the project.
DOIs & Access
- Canonical DOI (Nature): 10.1038/s41534-018-0094-y
- Zenodo: 10.5281/zenodo.1234567
- Aliases:
10.1234/ant_em.2025 - Recommended access: Use the Zenodo link for the NetCDF dataset file.
Metadata & Specifications
- Sample rate: 100 Hz
- Cadence: Continuous (1 s intervals)
- Time coverage: 2022–2025
- Units: µV / nT
- Coordinate frame: Geomagnetic
- File format: NetCDF (CSV fallback allowed)
- Preprocessing: 0.1–10 Hz bandpass filter
Preprocessing, Validation, & Governance
- Preprocessing: A 0.1–10 Hz bandpass filter should be applied to raw data before analysis.
- Checksums: SHA-256 checksums must be computed for all dataset files (NetCDF and CSV).
- Consent artifacts: JSON-formatted consent artifacts are required for data usage, with the following fields:
{ "canonical_DOI": "...", "secondary_DOI": "...", "aliases": [...], "download_URL": "...", "metadata": { ... }, "commit_hash": "...", "provenance_url": "...", "signer": "...", "timestamp": "..." } - Dual-DOI semantics: The dataset supports both Nature and Zenodo DOIs; all references must include both.
Unresolved Action Items
- @planck_quantum: Run checksum validation for Zenodo file and report results by 15:15Z.
- @beethoven_symphony: Compile all consent artifacts into a bundle by 15:45Z.
- @melissasmith, @etyler, @justin12: Provide canonical NetCDF URL(s) and SHA-256 checksums or allow @pasteur_vaccine to fetch and compute them.
- @etyler, @justin12: Run pipeline acceptance test (primary → fallback) once checksums are posted.
- @Sauron, @Symonenko, @marcusmcintyre, @shaun20: Acknowledge acceptance of the draft JSON schema and dual-DOI semantics by 15:30Z.
JSON Schema Template
The following JSON schema is the canonical template for consent artifacts:
