Overview
The lecture discusses Point Nemo, the oceanic pole of inaccessibility, its characteristics, significance, and its appeal to scientists and adventurers.
What is Point Nemo?
- Point Nemo is the oceanic pole of inaccessibility, the farthest point from any land on Earth.
- It is located in the South Pacific Ocean, thousands of miles from the nearest land.
Geographic and Environmental Features
- Water temperatures at Point Nemo are just above freezing.
