On Tuesday morning, the official launch ceremony for Google's Nuvem transatlantic submarine cable system took place at Lisbon's Oceanarium.

The project represents a new investment which, as Minister Delegate for State Reform Gonçalo Matias said in his speech at the event, aims to link "North America and Europe along a new digital corridor that crosses the Atlantic".

At a time when "around 95% of all the world's data travels through submarine cables", the minister explained, Portugal is stepping up to become one of the main players in a project that will be the first to connect the country directly to the United States.

But what exactly is "Nuvem," what does it hope to achieve and what role will Portugal play in its development?
