SOUNDING
/ˈsaʊndɪŋ/ — the act of measuring the depth of water
More people have stood on the Moon than at the bottom of this page. Below you: 10,935 metres of open water, and everything that lives in the dark. Descend at your own pace.
CHALLENGER DEEP
DEPTH 10,935 m · PRESSURE 1,086 bar · TEMP 1.6 °C
FIRST SOUNDING HMS CHALLENGER, 1875 · FIRST DESCENT TRIESTE, 1960
The pressure here is the weight of roughly 1,800 elephants standing on a car roof. And yet — sediment stirred by the Trieste's landing revealed a flatfish swimming away. Even at the very bottom of the world, you are not alone.
