What the chart cannot hold
What becomes visible when you follow sailing into a live volcano beyond the familiar map?
Deception Island is the drowned caldera of an active volcano whose breached crater wall forms Port Foster, one of the safest harbours in Antarctica. First visited by sealers around 1820, it hosted a Norwegian shore whaling station (1912–1931), then British, Argentine, Chilean and Spanish research stations, several destroyed by eruptions in 1967–1970. Today it is a major IAATO cruise-ship landing site and a scientific outpost.
Sealers from ~1820; Norwegian Hektor whaling station 1912–1931; British Operation Tabarin Station B from 1944; Argentine base 1948 and Spanish base 1989; eruptions 1967–1970; Antarctic Treaty governance since 1961.
