Descend Here — Fall to the Real Seafloor
Tap any point in the ocean and drop straight down from the surface to the seafloor beneath it. The depth is real — GEBCO’s bathymetry for that exact spot. The temperature and saltiness are real too, measured by the nearest live Argo float on its last dive. Watch the light fade, the pressure climb, and the animals change as you sink through the five zones of the sea. And where the measurements stop, this stops — no invented numbers below the floor or below the float’s reach.
Pick a spot above and we’ll drop straight down from the surface to the seafloor — reading the real depth, the nearest float’s measured temperature, and the animals that live at each layer.
How to read the descent
Three things are known for certain at any point you tap: the depth of the floor, the pressure at every level (about one atmosphere more for each 10 m down), and the light (gone by roughly 1,000 m, everywhere). The temperature and saltinessare only known as deep as a real float reached — so that line fades out partway down, and nothing is drawn into water no instrument has read. The deep ocean is the least-measured place on Earth; this view is honest about exactly where the knowledge ends.
