- Counts
- The area of the Arctic Ocean covered by at least 15% sea ice each day, in square kilometres, as the US National Snow and Ice Data Center measures it from satellites (Sea Ice Index, version 4, daily file). A day with part of the area missing is left out.
- Why it is here
- The ice at the top of the world, measured from orbit every day since 1987 and every other day before that.
- Cadence
- Daily, one day late. Newest complete day Nov 11. Read Nov 13, 02:40 UTC.
- Baseline
- The prior 30 days, 14 needed.

Asked often
- How much Arctic sea ice is there today?
- Sea ice covered 8,838,000 square kilometres of the Arctic on Nov 11 2026, as the National Snow and Ice Data Center measures it from satellites.
- Where does the $ICE number come from?
- Tickerz reads it from National Snow and Ice Data Center, Sea Ice Index version 4 (G02135), Northern Hemisphere daily extent. Daily, one day late. Each number is kept as it was first published, with a timestamped proof, and any later revision is shown beside it.
- Can I download the $ICE data?
- Yes, free and with no key: the full history as JSON at https://tickerz.com/api/indices/ice and every period as CSV at https://tickerz.com/api/indices/ice/history.csv.
Resolution
- Index
- $ICE Arctic sea ice. Rulebook v0.2, 2026-10-04.
- Prints
- Daily, one day late. The newest complete day is on the record after the daily proof at 12:40 UTC.
- As first published
2026-11-11 is not timestamped yet. The daily proof at 12:40 UTC adds it.
The number as first published is final for settlement. A revision by the source is shown beside it and never replaces it.
- Fallback
- A day prints when NSIDC posts it. A day with missing area stays open. A day NSIDC never posts is void.
- Precision
- Whole square kilometres: the published extent in millions of square kilometres, three decimals, times 1,000,000.
- Cost to move
- Not possible. It is the Arctic.
- Grade
- display. The newest days are near real time and can be reprocessed, which moves a day already printed; the record keeps the revision. Shown, not settled on.
- For a rulebook
- Settle on the number Tickerz first recorded for $ICE for the UTC day named in the contract, published at tickerz.com/x/ice and in GET /api/indices/ice, timestamped daily in Bitcoin with OpenTimestamps.
