South Pacific Ocean
The South Pacific Ocean covers 76,681,173 km² — the #1 largest of the 101 named ocean and sea areas. Here's its size, its neighbours and the live water conditions at its heart right now.
Boundaries & area: Marine Regions (VLIZ), IHO Sea Areas v3 — from the IHO “Limits of Oceans & Seas” (S-23). MRGID 1910.

How deep is the South Pacific Ocean?
The IHO sea-area dataset that draws this map records each sea's name, boundary and surface area — not its depth, which varies enormously from the shallow shelf at its edges to its deepest trench. Rather than quote a single misleading number, we measure the water column directly: the live ocean currents trace its motion, and the deep-ocean layers (Argo floats and the descend-here column, coming to the Ocean canvas) read real temperature and depth as you go down.
