A MEH combines an Electronic Chart Display and Information System (ECDIS), an Automated Identification System (AIS), shore-based marine information databases and advanced ship-to-shore communications. You can read more about it here. As part of the development of the MEH in this region additional surveys are being carried out to improve the source data for the charts. One Fathom Bank is being surveyed this month.
It is vital that these critical shipping lanes, which are some of the busiest in the world, are well surveyed. You can have the best ECDIS, AIS and comms in the world but with poor source data, eminating from old surveys, you can only rely on the chart so far. Better surveys = better source data = better navigation information for the Mariner. Job done.
