CHAPTER FOUR
Оглавление‘Almost there.’ Dave shook my shoulder and waved his hand at the pinging depth gauge, then switched on the bottom-scan sonar. We were about a hundred feet above the seafloor. A sound-etched picture of the terrain danced in ghostly blue waves across the display. The screen showed a stack of parallel lines between two walls of rock. The lines vaguely resembled a long rib cage.
‘Is that a dead whale?’ I asked, shifting right and reaching out to touch the LCD screen.
‘I doubt it,’ Dave said. ‘We’re coming down right over it. Let’s take a look-see.’
‘Dead whales are cool,’ I said. ‘They’re like gas stations in the desert. Propagules move from corpse to corpse on the seafloor. Some get to the vents and set up shop for good.’
‘That’s one theory,’ Dave allowed. ‘But I still don’t think it’s a whale.’
He pulled a graduated lever and the DSV shuddered as we dropped most of our steel ballast. ‘We’ll try for ten pounds below neutral. “Dance like a butterfly, sting like a bee.”‘ He pushed compressed air into the ballast tanks until we reached neutral buoyancy. Then he aimed the thrusters down and slowed our descent.
We hovered at about fifty feet, the sonar pinging insistently. He turned off the thrusters to avoid raising a cloud of silt.
‘Get that bottom light bar,’ he suggested.
I flipped the switch that turned on a bank of lights mounted directly below the pressure sphere.
‘I’m going to move some ballast forward.’ Dave pitched the nose down thirty degrees, giving us a wide-angle view of the bottom, and propelled us forward in controlled ‘flight,’ much more precise than weighted free fall. The DSV frame was equipped with a little railway system of steel weights that could be shifted fore and aft, or port and starboard, to adjust trim. This saved the sub from using thrusters, conserving power. The more power we kept in reserve, the longer we could stay on the bottom.
Dave thrust his hand into the data-glove box, a plastic cage containing a wire-lined black glove. With his left hand, he touched the instrument display and switched control of the lights to the glove. He expertly wriggled and pinched and twisted his fingers. The lights burned through a thin, whirling cloud of debris and flung brilliant white ovals on a small wooden fishing boat.
Not a whale after all.
‘It’s the Castle Rock II,’ he said with a dry chuckle. ‘An old wreck.’ The boat’s cabin thrust upright, intact after its long drop through the night, but the windows yawned broken and black like empty eye sockets. The crushed and splintered deck and hull showed the boat’s wooden ribs. ‘I thought I recognized it, but it’s been a couple of years. Field Number 37 should be a few hundred meters north, if we follow this shallow canyon. A little current today, but it seems to be on our side.’
I looked over the shattered hulk, lost in cold and perpetual dark, and wondered about the weather above. Would our recovery go smoothly? Last trip, we had spent three hours in foaming, choppy sea, our beacons flashing, before being hauled aboard the Sea Messenger.
All around us, the seafloor was covered with broken sheets of lava like lost pieces of a giant’s puzzle. The canyon walls, no more than fifty feet to either side, were not visible in the murk. The side-scanning sonar revealed that we were surrounded by what looked like columns in an ancient temple. Once, a lake of magma had pooled in the canyon and crusted over. Splits in the cap had allowed seawater to seep through and solidify the columns. The lava beneath the crust had then drained. As the molten basalt retreated, the sea had crushed the cap. Only the columns remained.
Dave pushed Mary’s Triumph backward with a few spurts of the thrusters. I could make out the fishing boat’s name, just as Dave remembered it, painted in a broken arc on the smashed stern.
‘Let’s go east,’ Dave said. ‘And up a bit. The boat dragged a few lines behind her when she went down.’
