New
York Times: The United States used to have several
submersibles âmdash; tiny submarines that dive
extraordinarily deep.
Alvin is the only one left, and after more than four
decades of probing the sea's depths it is to be retired. Its
replacement, costing some $50 million, is to go deeper, move
faster, stay down longer, cut the dark better, carry more
scientific gear and maybe âmdash; just maybe
âmdash; open a new era of exploration.
