What the chart cannot hold
What becomes visible when you follow arche des kerguelen beyond the familiar map?
Grande Terre (6675 km2, about three-quarters the size of Corsica) dominates the Kerguelen archipelago (7215 km2 total). Discovered in 1772, it has no indigenous or permanent population; activity is limited to science, conservation and regulated toothfish fisheries in its EEZ.
Sighted by Yves-Joseph de Kerguelen-Tremarec in 1772 and claimed for France; exploited by British and American sealers in the 19th century; reaffirmed by France (1893), attached to Madagascar (1924), then the TAAF (1955); Port-aux-Français station founded 1949.
