China participates in several\u00a0ambitious manned dives to explore the deepest part of the South China Sea this week<\/a><\/span><\/strong>. The Wall Street Journal details the commercial, scientific and military implications of this exploration:<\/p>\n The U.S. led undersea exploration and mining efforts for several decades thereafter, but commercial interest waned in the 1980s and 1990s because international prices for nickel, copper and other commodities thought to be most easily mined from the deep seabed at the time were insufficiently high.<\/p>\n The U.S. Navy used to operate three manned submersibles, including one, called the Sea Cliff, that was capable of going down to 6,000 meters, but didn’t replace it after its retirement because of defense cutbacks in 1998.<\/p><\/blockquote>\n Now, many experts say the U.S. risks falling behind potential commercial and military competitors as rising commodity prices make undersea mining more profitable, and China and Russia apply for rights to explore newly discovered deep-sea deposits thought to hold larger quantities of silver, gold, copper, zinc and lead in particular.<\/p><\/blockquote>\n The China Daily touts the scientific challenges of the dive:<\/a><\/span><\/strong><\/p>\n “As the submersible goes deeper, more pressure will be exerted on the craft, so the design requires a very high standard when it comes to preventing leaks,” said Xu Qinan, a researcher at the China Ship Scientific Research Center affiliated to China Shipbuilding Industry Corporation and Jiaolong’s chief designer. “We used titanium alloy to make the craft, which is flexible and sustainable under high pressure.”<\/p><\/blockquote>\n
