Underwater empires [Underwater research]

Engineering & Technology, 2007
Alongside the space race, which has been making headlines around the world over the last 50 years, there is another area of superpowers' rivalry that lies beneath the oceans. The author appraises the latest moves of supremacy-driven 'underwater empires' (underwater research) and the technology behind them.
