## What Are Ocean Drones? A Deep Dive

Ocean drones, also known as marine drones, underwater drones, or autonomous underwater vehicles (AUVs), are unmanned vehicles designed for operation on or beneath the ocean surface. Unlike remotely operated vehicles (ROVs) that require constant tethered control, ocean drones operate autonomously, following pre-programmed routes or responding to real-time data. They come in various shapes and sizes, each designed for specific tasks, ranging from surface gliders that collect data on wave patterns to deep-sea explorers capable of withstanding immense pressure.

> **EXPERT TIP:** The key to understanding ocean drones is recognizing their autonomy. This independence allows them to cover vast distances and operate in hazardous environments, things human-crewed vessels often struggle with.
