One of the biggest barriers to protecting the ocean — and our future — is that we don’t know much about what’s going on under the water. Even though it covers around 70% of the planet, most of it remains unexplored. We know more about the surface of the moon than we do about the deepest parts of the ocean floor. This is partially because it’s an incredibly challenging environment for technology. The pressure is crushing, communication is extremely difficult (GPS and WiFi don’t work underwater!), and saltwater kills electronics, which makes long-term monitoring challenging.
