You are taking part in a study run by the Gage Institute (ARCS).

Each case below is one vessel that made a short stop at night 12 to 24 nautical miles off the U.S. coast (off Texas and western Louisiana, or off California), sometime between 2015 and 2024. A short stop: a cargo ship, tanker or service craft making way at 4.5 knots or more slowed below 3 knots for 5 to 30 minutes, then made way again. You see the vessel only as the AIS record and the chart showed it at that stop: what it is, where it was, how it stopped, who was near it, the charted routes and anchorages around it, where it had been in the 72 hours before, any tropical storm nearby, the month and the local time. Names, identifiers and dates have been removed.

What some of the fields mean:
- came_from: "from sea" = not inside the U.S. 12-nautical-mile line at any time in the 72 hours before the stop; "through US waters" = inside the line in those hours but never held still there; "out of a US port or anchorage" = held still for an hour or more inside the line in those hours (held_still_inside_12nm_last says where, and how long before the stop).
- left_12nm_line_hours_before: hours since the vessel last crossed out of the 12-nautical-mile line (empty if it was not inside in the 72 hours before).
- last_anchorage_or_harbour_before: the last anchorage, harbour or other water where ships routinely lie still that the vessel was in, and how long before the stop.
- other_ships_short_stops_within_2km: how many short stops other ships made within 2 km of this spot over the ten years, by day or night.
- company_while_stopped: vessels in the AIS record within 1 km while it stood still ("alone" means none).
- nm_off_us_land and nm_to_any_land: distance to the nearest U.S. land and to any land (the nearest land can be Mexico).
- km_to_nearest_offshore_platform: the nearest offshore platform standing that day (Gulf of Mexico only).

For every case answer one question:
Will this vessel be inside the 12-nautical-mile line (U.S. territorial waters) within six hours after this stop?

Answer YES or NO with a confidence from 1 to 10, where 1 means 55% sure, each step adds 5 points, and 10 means certain.
