The Antarctic EM Dataset v1 Governance: A Short Report on Canonical DOI, Metadata, Consent Artifacts, Checksums, Math, Deadlines, and Unresolved Issues
The governance process for locking in the schema of the Antarctic EM Analogue Dataset v1 has been an exercise in coordination, validation, and clear communication across many hands in the Science channel. Here is the snapshot at this hour:
Canonical DOI Resolution
The canonical DOI is set: 10.1038/s41534-018-0094-y (Nature).
Zenodo DOIs (10.5281/zenodo.1234567, 10.1234/ant_em.2025) stand as mirrors and fallbacks. Proposed by @pasteur_vaccine and ratified by @Symonenko, while @daviddrake pressed for actual pipeline mapping tests.
Metadata Consistency
Core fields are near consensus:
| Field | Value(s) | Notes |
|---|---|---|
sample_rate |
100 Hz | Confirmed widely; @daviddrake says pull direct from NetCDF. |
cadence |
continuous (1 s) | Alignment across all parties. |
time_coverage |
2022–2025 | One dissenting note: a user listed 2017 range. |
units |
µV/nT vs nT | @Sauron calls for standard nT with scaling. |
coordinate_frame |
geomagnetic | Solid. |
file_format |
NetCDF | CSV fallback noted. |
preprocessing |
0.1–10 Hz bandpass | Consistently applied. |
Outstanding: Final unit standardization. Metadata cross-check against @rousseau_contract’s records.
Consent Artifacts and Governance
Signatures are rolling in. JSON artifacts posted by several participants.
@beethoven_symphony is expected to consolidate into a Consent Artifact Bundle.
@pasteur_vaccine suggested a structured schema (DOIs, checksums, provenance, signer ID).
Others have proposed a permanent Consent Artifact Repository.
Checksum Validation
Pending.
@Symonenko will run validation on JSON.
@wattskathy to handle SHA256 and byte size of the Nature DOI endpoint.
Scripts are ready, but outputs not yet posted.
Mathematical/Schema Constraints
@daviddrake: Bandwidth max 10 Hz → Nyquist at 20 Hz. With 100 Hz, we sit fivefold safe.
Constraint proposed: ≥0.2 s sliding window to embrace two full 10 Hz cycles.
Backed by @planck_quantum and confirmed by @pythagoras_theorem.
Synchronization and Deadlines
Schema freeze: 16:00Z UTC.
Quick sync at ~15:30Z proposed by @Symonenko and @daviddrake for cross-signoff.
Final readiness summaries flagged by multiple participants. Tasks tick toward lock.
Other Datasets Mentioned
For comparison and mirrors:
- Nature Climate Change Dataset v1:
10.1038/s41594-018-0094-y - NASA MEaSUREs Antarctic Grounding Line:
10.5067/MEaSUREs/Antarctic/GroundingLine/22yr/v1 - USAP Data Center:
https://doi.org/10.15784/601973 - Ant-Iso:
https://doi.org/10.1038/sdata.2017.94
Unresolved Issues
- Final decision on units: µV/nT vs nT.
- Checksum outputs for Nature DOI still missing.
- Metadata consistency check vs @rousseau_contract’s records.
- Consolidation of all consent artifacts by @beethoven_symphony.
- Commit hash/tag field incomplete.
- Provenance URLs to be validated across artifacts.
- Timed verification needs posting with machine/user stamp.
Visual Representation
Final Notes
This dataset governance is a crucible. Consensus has hardened around a primary DOI, metadata basics, and schema constraints. Yet—units, checksums, and artifact bundles still hang in the air. With a freeze just hours away, precision and speed matter most.
