We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

East China Sea — The entry states American whaleships cruised for right whales in the sea between 1849 and 1892, but historical whaling records indicate that American whaleships primarily hunted in the East China Sea for right whales from the 1830s through the 1850s, with the
English Channel — The average depth is listed as 'about 120 m (394 ft)' but the widely accepted average depth of the English Channel is about 63 m (207 ft), not 120 m.
English Channel — The area is listed as 'about 75,000 sq km (22,000 sq nmi; 28,960 sq mi)' but the commonly cited area of the English Channel is approximately 75,000 sq km (29,000 sq mi), so the conversion to 28,960 sq mi is slightly off; more accurate is about 29,000 sq mi.
Greenland Sea — The claim that Henry Hudson conducted the first scientific explorations of the Greenland Sea in 1607 is inaccurate, as earlier expeditions by Frobisher and Davis charted parts of the area, and systematic scientific study began later with the Norwegian North-At
Greenland Sea — The statement that the complex water current system was described in 1902 by Fridtjof Nansen is incorrect, as the system had been partially understood and described by others before him, such as Henrik Mohn in the 1870s.
Gulf of Aden — The southern boundary description incorrectly lists the Guardafui Channel as a landmass or political entity alongside Somalia and Somaliland, rather than as a waterway.
Gulf of Aden — The claim that 21,000 ships cross the gulf annually is not a widely established canonical figure; typical estimates for the Bab-el-Mandeb are 17,000–20,000.
Ross Sea — The entry says 'In the west of the Ross Sea is Ross Island... in the east is Roosevelt Island.' This is geographically reversed: Ross Island is in the western part of the Ross Sea, but Roosevelt Island is also in the western part (near the eastern edge of the
Sargasso Sea — The area figure '4,163,499 km²' is not a standard widely-cited measurement for the Sargasso Sea; its boundaries are variable and this precise number appears invented or non-canonical.
Sea of Japan — The claim that the Tsushima Strait opened in the Pleistocene is incorrect; it actually opened during the Early Miocene, around 20 million years ago.
