PRELIMINARY DESCRIPTION AND SPECIFICATIONS FOR A DANISH COASTAL MARINE DATA COLLECTION SYSTEM

To an increasing extent Denmark is faced with a series of problems linked with the safe navigation of large and deep draft ships through the Danish waters. This is particularly important in the narrow and shallow fairways of the Baltic approaches where the waters have a transient nature because of their position between the fresh Baltic and the saline Kattegat. Instantaneous sea level, sea state, current, sound speed, ice probability and buoyancy are among the factors to be considered when navigating the Danish straits. The Royal Danish Administration of Navigation and Hydrography has undertaken the job of developing a system to measure or compute these parameters, providing "real-time" oceanographic data to transiting ships.
