Explore the reports behind the markers
Find a wreck notice, a container lost overboard, or an object reported adrift. Start with a theme, narrow to a sea, and open the original warning to see what was actually reported.
01 / MAP EXPLORER
Navigational warnings about wrecks, shoals and submerged obstructions. These records are not a complete inventory of shipwrecks; several notices may refer to the same object.
Explore reported positions →02 / MAP EXPLORER
Navigational warnings about containers lost overboard, derelict vessels and debris. Markers retain the position reported in each notice: drifting objects may have moved since then.
Explore reported positions →Every marker belongs to a warning. Its issue date, reported position and source stay together. Map counts refer to warning records, not unique objects, and each page states how much of the archive it shows.
A cancelled notice does not prove a wreck was removed. Incident replays connect selected accidents to dated official reports and documented outcomes.
Reported locations are historical observations, not live vessel tracking. Coverage varies by source and period. Not for navigation; use official broadcasts and charts.
