Underwater Technology, Inc.) now offers the remarkable REMUS 6000, its numeric tag a nod its diving depth.With the software and electronics of the smaller, proven, multi-role REMUS 100, the larger REMUS is sure to impress a U.S. Navy contemplating missions as mind-blowing as patrolling transatlantic cables; knocking out seabed listening posts or hardening vital national infrastructure like harbors and offshore oil platforms. Mission possibilities, especially recce, are as boundless as the imagination.Yet, despite the financial clout of Kongsberg Maritime and its worldwide researcher ties, the pioneering

French Port: First Phase of Subsea Cables

The port of Marseille-Fos sets the path towards the maritime data-hub concept: a global digital gateway offering smart and reliable landing infrastructure for subsea cables.Globalization does not simply mean more ships; it also means more information flows. No wonder that data traffic is predicted to grow at a rate of 45% per year over the next decade. This dramatic increase in volume, along with the diversity of the content which is exchanged, requires upgraded interconnection infrastructure as well as data storage facilities. The port of Marseille-Fos is ready. The port has announced the construction
