AIS tanker transits — 15-day average (IMF PortWatch AIS; faint = raw daily)our optical ≥200 m presence (per pass)optical above AIS trendbelow
Two instruments, read the gap. The grey line is a 15-day average of AIS-reported tanker transits through the strait (faint grey = raw daily; IMF PortWatch AIS); the blue dots are our optical ≥200 m large-vessel presence, one per satellite pass. Both are indexed to their own average over this window (100 = each series' own baseline) — they measure different things (daily transits vs. a one-instant hull count), so only their trends are comparable, never their raw levels. Each stem is that pass's divergence from the AIS trend: blue where our AIS-independent sensor reads relatively more large-vessel activity than AIS transits (49 passes), amber where less (58). Both are FLOORS — AIS misses vessels that go dark, and cloud hides hulls from us. We show the gap; we do not tell you its cause.
Method
Method and limits. Findings on this page are derived exclusively from publicly available satellite imagery (Copernicus Sentinel open data), analyzed after the imagery entered the public catalog. We publish counts and individual detections — position and approximate size — exactly as the instrument recorded them. Detections are anonymous: we never publish vessel identities or names, and we never track an individual vessel across dates, because the instrument cannot support those claims. Nothing we publish is fresher than the public availability of the underlying scene; the instrument observes on a fixed orbital calendar and cannot be tasked. Machine counts from optical imagery are approximate: cloud hides real vessels and can also fabricate detections, so every figure is a machine count and its measured error rates are published beside the data — image review calibrates those rates; it never silently corrects a number. Observations are dated — they describe what the instrument saw on the stated date. Corrections and revisions are shown, never silent.

What this instrument sees: sunlit hull stock at one instant, vessels ≥200 m. What it cannot: night, water under cloud, vessels under 200 m. One row per satellite pass. Counts are after quality filtering (“gates”); see error notes below.
Presence, pass by pass
Large vessels (≥200 m) present on 9 of the last 10 clear passes · longest run without one: 1 pass. Latest pass 2026-08-09: 1 detected.
10212244101
One mark per pass, oldest first (2026-07-08 → 2026-08-09); filled = at least one vessel ≥200m. Nothing is connected: at these counts the difference between adjacent passes is inside the instrument’s own contamination band, so a line would draw noise as change. Presence is what this instrument can support; level is not.

Detections
These crops are machine-selected by a published deterministic rule — the strongest detections, and the largest reject of each filter. Not hand-picked, not human-verified: the rule can be recomputed, so the set cannot be cherry-picked. Each image carries its own honest label.
Strongest detections — what we count
Rejected — what the filters remove (why the count is disciplined)
What this instrument can and cannot do
Detections ≥200 m. Which error band applies depends on the sea state the pass was measured in — the regime is printed on every row of the full record below.
- flooded — contamination 26% (90% CI 16–39%)
- detector-active — contamination 8% (90% CI 3–17%)
- detector-quiet — contamination 8% (90% CI 3–17%)
- cloud-skipped — no band: these passes were excluded from the calibration, so no error rate here is ours to claim
Measured under: regime1, 2026-07-28, on the current post-OCM production gate (no structural drift: measured_thresholds match the live profile).
Error bands measured 2026-07-28 · last blind calibration 2026-07-28 (regime1) · 5 passes observed since (caveat at 10).

“machine” = automated count, not verified image by image. One row per satellite pass; the survey above summarizes these.
Columns marked uncharacterised (≥150 m, ≥100 m) are below ≥200 m, the class this instrument’s error rates were measured at. They are part of the census and shown in full, but the published ship-loss and contamination bands do not cover them — displaying a count is not characterising it.
Change — latest observation
| reference | date | |
|---|---|---|
| previous pass | — | not published — adjacent readings differ by less than this instrument’s own contamination band, so the arithmetic would be band noise wearing the clothes of change. Presence, not level, is what it supports |
| ~1 week | — | not published — adjacent readings differ by less than this instrument’s own contamination band, so the arithmetic would be band noise wearing the clothes of change. Presence, not level, is what it supports |
| ~1 month | — | not published — adjacent readings differ by less than this instrument’s own contamination band, so the arithmetic would be band noise wearing the clothes of change. Presence, not level, is what it supports |
| ~1 year | — | not published — adjacent readings differ by less than this instrument’s own contamination band, so the arithmetic would be band noise wearing the clothes of change. Presence, not level, is what it supports |
Reference selection is mechanical: nearest earlier observation to (latest − 7 / 30 / 365 days), within ±2 / ±7 / ±15 days; no observation in tolerance renders as “—”. Changes are shown against named dates only — never against an average.

Revisions — shown, never silent
2026-07-19 — BACKFILLED 2026-08-05 (third-audit item 2): the 2026-07-19 re-gate under the ratified BAM census operating point (OmniCloudMask cloudfrac >= 0.8, gate=cloud_ocm, and shape-coherence fill_min 0.50, gate=wisp; curator-ratified 2026-07-19) was applied to all 115 dates then on disk but never logged -- the ledger's last entry (2026-07-17 (c)) left 2026-07-08 >=300 m at 20 while the table served 2. Old counts reconstructed from per-detection gate labels: cloud_ocm and wisp are terminal gates and the profile is unchanged since 2026-07-19 (verified uniform across all 120 gated files), so a detection carrying either label today was clean before the re-gate. Cross-check: the reconstruction reproduces the ledger's 2026-07-08 >=300 m endpoint (20 -> 2) exactly. 263 count(s) across 69 row(s) changed. Method effect, not a world event.

2026-07-17 (c) — point floor added (point_min_area_px 7, curator-ratified): detections under 7 px are below the instrument's discrimination floor at 10 m/px — curator-labeled glitter sparkle is 4-6 px, the smallest ruled ship 8 px. A resolution floor, not a discriminator: it says 'cannot tell', never 'not there'. Only the vessels tail changes; no >=100 m count moves. 68 count(s) across 68 row(s) changed. Method effect, not a world event.

2026-07-17 (b) — catalogued fixed_features gate added (curator-ratified from the restored-sheet adjudication): one BAM islet whose centroid jitter leaked it past per-detection recurrence counting, plus a Hormuz tidal sandbar and sand peninsula tip that recur too rarely for any count threshold on the 11-date corpus; catalogued geography is now killed first, gate value 'feature'. 61 count(s) across 30 row(s) changed.

2026-07-17 — re-gated under fixed_min_count (Hormuz 6, BAM 15, curator-ratified): the recurrence gate previously branded a detection fixed on a single cross-season pair, which on busy water killed transients and real ships (adjudicated chip tranche, s2audit_adjudications.json). 160 count(s) across 66 row(s) changed. Method effect, not a world event.

2026-07-17 — the series was backfilled from 12 to 115 observations (every pass since 2025-06-01). With observations now spanning ≥120 days, the fixed-feature check armed for the first time and excluded permanent bright features (reefs, moorings) that earlier rows had counted as vessels — e.g. 2026-07-13 ≥150 m 17 → 14, 2026-07-10 ≥300 m 2 → 1, 2026-07-08 ≥150 m 84 → 73. All 12 initial rows were recomputed. Method effect, not a world event.
Error notes — measured, about the instrument
- Every count on this page is a machine count. Image review happens continuously behind the instrument, but its product is the measured error rates — never a corrected number in the table. At the single-detection level a machine count can be wrong in ways only the class-level rates capture.
- Cloud both hides real vessels and fabricates detections; high-cloud rows are flagged by their own cloud column and read as lower bounds.
- The number beside each regime label is the measured false-detection density (per km²) on hull-free water that day; higher means a noisier scene, whatever the label says. The labels name what the gauge graded, not why it graded that way: it counts false detections in empty-water windows, observing no sun angle, geometry or reflectance. “blind” means the gauge windows themselves were cloud-covered, so the count is recorded but its scene quality is unmeasured.
