MacArtney, Denmark, has launched its first underwater winch system. The company said the system is capable of launching and retrieving an extensive range of underwater oceanographic equipment at any preset interval range to provide regular data about the water column via a fibre communication link onshore.rn"One of the many application possibilities for the underwater winch system is collecting water column data to accurately adjust sonar data, compensating for a rangernof underwater influences that can distort sonar readings," said MacArtney. "Sensors provide onshore computers with the measurements they need to perform adjustments that make the sonar data as accurate as possible, processing the data digitally to account for distortions."
