Subsea communication refers to the methods and technologies used to transmit data and information underwater. This is essential for various applications, including oil and gas exploration, marine research, and underwater robotics. The communication systems often rely on fiber optic cables, acoustic signals, or electromagnetic waves to connect underwater devices to surface stations. These systems enable real-time data transfer, allowing for monitoring and control of underwater operations. For instance, subsea sensors can collect environmental data, while remotely operated vehicles (ROVs) can be controlled from the surface. Effective subsea communication is crucial for safety and efficiency in underwater activities.
