Arctic Drift

southerly moving ice pack. That rock pile probably diverted some of the ice floe, while breaking up a good deal more piling up on its northern shore.”

“That is a pretty direct path from your X,” Giordino noted.

“That’s the presumption. No telling how far the ships actually moved before falling through the ice. But I’d like to start with a ten-mile grid just above these islands and then move north if we come up empty.”

“Sounds like a good bet,” Giordino agreed. “Let’s just hope they dropped to the bottom in one piece so they’ll give us a nice, clean sonar image.” He looked at his watch. “I better rouse Jack and get the AUV prepped before we get on-site. We’ve got two aboard, so we can lay out two separate grids and search them simultaneously.”

While Pitt laid out the coordinates for a pair of adjoining search grids, Giordino and Dahlgren prepared the AUVs for launching. The acronym stood for autonomous underwater vehicles. Self-propelled devices that were shaped like torpedoes, the AUVs contained sonar and other sensing devices that allowed them to electronically map the seafloor. Preprogrammed to systematically scan a designated search grid, they would cruise a few meters above the seabed at nearly ten knots, adjusting to the changing contours as they ran.

As he passed just north of the Royal Geographical Society Islands, Captain Stenseth slowed the Narwhal as they entered the first of Pitt’s search grids. A floating transponder was dropped off the stern, then the ship raced to the opposite corner of the grid where a second buoy was released. Keyed to the orbiting GPS satellites, the transponders provided underwater navigation reference points for the roving AUVs to keep on course.

On the stern of the ship, Pitt helped Giordino and Dahlgren download the search plan into the first AUV’s processor, then watched as a crane hoisted the large yellow fish over the side. With its small propeller spinning, the AUV was released from its cradle. The device shot forward and quickly dived beneath the dark, rolling waters. Guided by the bobbing transponders, the AUV scooted to its starting point, then began weaving back and forth, scanning the bottom with its electronic eyes.

With the first vehicle safely released, Stenseth piloted the ship north to the second grid area and repeated the process. A biting wind cut through the men on the deck as they released the second AUV, and they hurried to the warmth of the nearby operations center. A seated technician already had both search grids displayed on an overhead screen, with visual representations of both AUVs and the transponders. Pitt slipped out of his parka as he eyed several columns of numbers quickly being updated on the side of the screen.

“Both AUVs are at depth and running true,” he said. “Nice work, gentlemen.”

“They’re out of our hands now,” Giordino replied. “Looks like it will take about twelve hours for the fish to run their course before surfacing.”

“Once we get them back aboard, it won’t take long to download the data and swap batteries, then we can set ’em loose again on the next two grids,” Dahlgren noted.

Giordino raised his brows while Pitt shot him a withering look.

“What did I say?” he asked in a bewildered tone.

“On this ship,” Pitt replied, a razor-sharp grin crossing his face, “the first time’s the charm.”

Sixty miles to the west, the Otok churned through the wind-whipped waters on a direct path to the Royal Geographical Society Islands. In the wheelhouse, Zak studied a satellite image of the islands through a magnifying glass. Two large islands dominated the chain, West Island separated by a thin channel from the smaller East Island. The Mid-America mining operation was located on the southern coast of the West Island, facing Queen Maud Gulf. Zak could make out two buildings and a long pier in the photograph, as well as evidence of an open-pit mine nearby.

“A message came in for you.”

The Otok’s unshaven captain approached and handed Zak a slip of paper. Opening it up, Zak read the contents:

Pitt arrived Tuktoyaktuk from D.C. early Saturday. Boarded NUMA research vessel Narwhal. Departed 1600, presumed destination Alaska. M.G.

“Alaska,” he said aloud. “They can’t very well go anywhere else now, can they?” he added with a smile.

“Everything all right?”

“Yes, just a tardy effort by the competition.”

“What’s our approach to the islands?” the captain asked, peering over Zak’s shoulder.

“The south coast of West Island. We’ll make for the mining operation first. Let’s run right up to the pier and see if anyone is home. It’s early in the season, so they may not have opened up summer operations yet.”

“Might be a good place to dump our captives.”

Zak gazed out the aft window, watching the barge that was tailing behind wallow in the turbulent seas.

“No,” he replied after contemplation. “They should be quite comfortable where they are.”

Comfortable was hardly the sentiment that came to Rick Roman’s mind. But under the circumstances, he had to admit they had made the best of things.

The cold steel deck and bulkheads of their floating prison quickly sapped their efforts to keep warm, but a solution lie in the debris left behind. Roman organized the men under penlight and had them attack the mound of tires. First, a layer of the old rubber was laid on the deck, then a series of walls were built up, creating a smaller den where all the men could still fit. The mooring ropes were then unwound and draped over the tire walls and floor, creating an extra layer of insulation, as well as padding for the men to lie on. Huddled into the tight enclave, the men had a combined body heat that gradually forced a rise in the temperature. After several hours, Roman flashed his light on a bottle of water at his feet and noted an inch or two of liquid sloshed atop the frozen contents. The insulated den had warmed above freezing, he noted with some satisfaction.

It was the only satisfaction he had received in some time. When Murdock and Bojorquez returned after a two-hour inspection of the barge’s interior, the news was all bleak. Murdock had found no other potential exit points astern of their storage hold, save for the cavernous holds themselves. The mammoth overhead hatch covers might as well have been welded shut for the chance they had at moving them.

“I did find this,” Bojorquez said, holding up a small wood-handled claw hammer. “Somebody must have dropped it in the hold and didn’t bother to retrieve it.”

“Even a sledgehammer wouldn’t do us a lot of good on that hatch,” Roman replied.

Undeterred, Bojorquez began attacking the locked hatch lever with the small tool. Soon the tap-tap-tap of the pounding hammer became a constant accompaniment to the creaking sounds of the moving barge. Men lined up to have a go at the hammer, mostly out of boredom, or in an attempt to warm themselves from the exertion. Against the incessant rapping, Murdock’s voice suddenly raised over the din.

“The tow ship is slowing.”

“Cease the hammering,” Roman ordered.

Ahead of them, they could hear the engines of the icebreaker slow their deep-throated drone. A few minutes later, the engines dropped to an idle, then the barge bumped against a stationary object. Listening in silence, the men anxiously hoped that their frozen imprisonment was over.

The Royal Geographical Society islands appeared as a mass of buff-colored hills rising above the choppy slate waters. The islands were christened by the explorer Roald Amundsen in 1905, during his epic voyage on the Gjoa, when he became the first man to successfully navigate the length of the Northwest
