Underwater Communications

As the hydrographic data for mainly is collected from a vessel with virtually no underwater communication issues, it is gaining interest. Real-time data monitoring from AUVs, communication with AUVs and between AUVs (when they are autonomously diving as a swarm) are developments that gain traction in these days.

Technology in Focus: Underwater Electromagnetic Propagation

Underwater wireless communications links have almost exclusively been implemented using acoustic systems. Optical links have proved impractical for many applications. Although underwater radio links were experimentally evaluated in the pioneering days of radio, they did not meet the requirements of the time. Given modern operational requirements and digital communications technology, the time is now ripe for re-evaluating the role of electromagne... (read more)

Communications to the Deepest Point on Earth

In March 2012, filmmaker and explorer James Cameron successfully completed his one-man dive to the bottom of the Mariana Trench. The dive was the centrepiece of the Deepsea Challenge expedition, a joint scientific project by Cameron, the National Geographic Society and Rolex to conduct deep ocean research and exploration. A range of technological innovations were required for the venture, one of which was a reliable method for sending voice and d... (read more)
