A searchable archive records vessel passages through seven Great Lakes chokepoints, using public AIS tracks.

Landing page captured for the 2026-09-23 issue.

For: Great Lakes ship watchers and shipping researchers
Worth noticing: Passage times are interpolated from AIS samples and described as accurate to about fifteen minutes.

Field notes

Records are organized around individual vessels and seven named chokepoints, with vessel pages including Soo transits, Duluth canal runs, seasonal first and last passages, and monthly and yearly counts. The 2025 report gives a comparison with 2024 and breaks out traffic by location. The separate Seaway table is reproduced with its source timestamp and Eastern-time context, and is explicitly described as a schedule rather than a live position feed.
