Our adventure began at three in the morning. Loading up our tugboat, we pulled out of San Diego. The harbor lights sank quickly behind us. Ten hours later we were cutting through the chop of the Pacific, with nothing to see but the tossing ocean. So it wasn't hard to spot the Maersk Launcher, a 300-foot mining research vessel, that we'd come to join. All we had to do was get on board. While the launcher dangled a rope ladder above us, the tugboat backed in. With swells over ten feet, timing was everything. At the top of the wave, we took a leap of faith and landed in the new world of deep sea mining.
