Daylight was breaking over the central Pacific and coffee brewing aboard the MY Hanse Explorer. Between sips, about a dozen scientists strategized for the day ahead. Some would don wetsuits and slip below the surface to collect water samples around the southern Line Islands' numerous coral reefs. Others would tinker with the whirring gizmos and delicate machinery strewn throughout the 158-foot research vessel. All shared a single goal: Be the first research group to bring a DNA sequencer out into the field to do remote sequencing in real time. Against an ocean of odds, they succeeded.
