in the yards in Finland. Whereas the original Seaquest and her sister ship Sea Venture had been derived from the Akademik-class Russian research vessel, designed originally for acoustic submarine surveillance during the Cold War, Seaquest II was an entirely new concept planned from scratch to IMU
specifications. Her state-of-the-art navigational features included a dynamic positioning system, using lateral thrusters and ballast control to maintain stability in virtually any sea conditions–vital for position-keeping and search tracking as well as to maintain a level platform for laboratory work. She could launch remote-operated vehicles and submersibles, using either deck cranes or an internal docking berth which allowed underwater egress. Like all IMU vessels she had a defensive capability, with a gun pod retracted below the foredeck. And, crucial for polar research, the ice-strengthened hull allowed her to plough through the shattered sea ice which choked the coastal waters north of the Arctic Circle even in early summer.
Jack was still casting a critical eye over her deck arrangements as the Lynx bounced on to the helipad and the rotors shuddered to a halt. While the awaiting crewmen secured the undercarriage to the deck, Jack eased off his helmet and released his seat belt harness. The sun was burning off the sea mist and ahead of him he could see the entire length of the superstructure, gleaming white in the pellucid Arctic light. He was in his element again, and his excitement showed as he leaned back and grinned at Maria and Jeremy. “Welcome to Seaquest II.
This is where the fun really begins.”
James Macleod led them directly from the helipad through the hangar entrance and down a steep gangway into the bowels of the ship. They were joined by Costas, who had been winched down from the US Air Force Chinook fifteen minutes before and had been busy uncrating his cargo on the stern deck. He looked as if he needed about a week’s sleep, but with his sleeves rolled up on his burly forearms and fresh smears of grease on his beloved overalls, it was clear he was not going to waste a moment getting the equipment operational.
They reached the lower deck and Macleod ushered them through an open door into a brightly lit lecture room, gesturing for them to stand beside a projector screen to the right of the door. Ranged in front of them on plastic chairs was a motley group of about thirty men and women, some talking intently among themselves and others hunched over laptops and sheaves of printouts. They all looked up as Macleod entered, and Jack could see several bearded blond men with the Danish flag on their parkas, a couple of native Greenlander faces, and a number of men and women wearing the navy blue sweaters of the US Air Force.
He nodded courteously to a man in the front row splayed languidly on his chair and stroking his sideburns, so lost in thought that he failed to catch Jack’s gesture. Lanowski was a brilliantly adaptive engineer who had been indispensable to IMU since they had poached him from MIT, but he had a manner calculated to irritate almost everyone who came into contact with him.
“People, you should all be familiar with Jack Howard, my colleague at IMU. At least from the TV news.” Jack looked distinctly uncomfortable, and Macleod gestured to the other three. “Dr. Maria de Montijo and her graduate student Jeremy Haverstock from Oxford, though he’s originally from the States. Costas you already know.”
They gazed with evident curiosity at Jack, a face familiar even to those who did not know him personally. Costas grinned at a few old friends, several of whom had got to know him very well when he had attended the project briefing several weeks previously at the IMU campus in Cornwall.
“We’re an international team, as you can see,” Macleod said to Jack. “Officially the project’s a collaboration with NASA and the Geological Survey of Denmark and Greenland, and there are also a couple of guys from the International Ice Patrol. We’re all doing our own thing, glaciology, biology, palaeoclimatology, but we’re pooling basic resources. IMU provides the research vessel, NASA the satellite imagery and GSDG the aerial photography and laser altitude measurements. A lot of the work’s just monitoring, making sure the ice conditions are safe enough for us to get the samples we need. With the summer melt almost in full swing we’re working against the clock. I wanted you here for a quick meet and greet. Any questions for this group now, fire away.”
“I don’t want to detain anyone, so just a few,” Jack said. “The Greenland ice cap, the inland ice. Can we have a swift rundown on its age and significance?”
“Most of it dates from the last two hundred and fifty years, and most of the ice at Ilulissat is from the last hundred thousand years,” Lanowski said, brushing his shoulder-length hair from his face. “It’s an outstanding survival from the last glaciation of the Quaternary.”
“Meaning?” Maria asked.
“Meaning the Ice Age we all know about, the one that ended ten thousand years ago when the ice sheets receded,” Lanowski explained, sighing impatiently.
“Quaternary is a geologic term encompassing the recent Ice Age, beginning about one-point-eight million years ago, encompassing many episodes of advance and retraction in the ice. We’ve been in one of those warm spells for the last ten thousand years.”
“So what makes Greenland so special?”
“There are plenty of glaciers around the world dating from the Ice Age, and of course there are the polar ice caps,” Macleod said. “But the Greenland ice cap is the last remnant of the continental ice sheets that covered the northern hemisphere until ten thousand years ago. It’s a fantastic window into the past, as exciting to me as any of your archaeological discoveries.”
“Which brings us to why you’re here,” Jack said.
“It’s still early days, but the results are very promising,” one of the Danish scientists said. “We’re mostly looking at air bubbles trapped in the ice as it formed, preserving a detailed record of atmospheric conditions in the Ice Age.
The calving front is now exposing areas of ice formed very recently, in a cold snap just prior to the Great Melt ten thousand years ago. It’s an unparalleled opportunity, the first time any research like this has been possible.”
“Global warming has its uses,” Costas remarked wryly.
“We can’t turn back the clock now, so we may as well get all the science out of it we can,” the Dane replied.
“One question,” Maria said. “You wouldn’t get me going anywhere near that calving front we just saw on the glacier. How do you get your samples?”
“We drill cores, just like a sedimentologist or an oil prospector on land,” Macleod said. “Each band of ice represents a cold spell, sometimes hundreds or thousands of years. It’s a bit like dendrochronology, tree-ring dating.” Macleod turned and looked intently at Jack. “Which brings me to why you’re here.”
“I’m still baffled,” Maria persisted. “You’ve still got to get close up to the ice to drill a core.”
“All will be revealed.” Macleod beamed at her and started towards the door, nodding his thanks to the assembled group and turning to Jack. “Follow me.”
Seaquest II was marginally smaller than her predecessor, more economical on space to maximise fuel efficiency and endurance, but with a displacement of a little over seven thousand tons she was still one of the largest research vessels afloat, and it took them a good five minutes to reach the upper accommodation deck. Without stopping Macleod pointed at a line of cabins with their names pinned on the doors, their bags already visible inside. At the end of the corridor they walked into a room that occupied the entire forward end of the accommodation block, directly below the navigation room and wheelhouse. The layout had been Jack’s idea, providing a dedicated control and observation room for project staff, avoiding the problems of sharing bridge space with crew which they had recently experienced on Sea Venture in the Golden Horn. The room had a director’s chair set on a dais in the centre, a duplicate of the bridge radar screen, four computer workstations arranged in an arc radiating from the dais and viewing seats with high-powered scopes set up against the window, a continuous sloping screen that wrapped around the front and sides of the room.
With the mist now lifted completely it gave them a dazzling view of the sea to the west, a deep blue expanse dotted with fragments of white, the low form of Disko Island just visible off the starboard bow and the Canadian shore of the Davis Strait somewhere beyond the horizon.
They had been followed from the lower deck by the shambling form of Lanowksi and by one of the Greenlander scientists, an Inuit woman of striking appearance who pointed to the coffee machine as they entered the room. Macleod grunted, then nodded and proceeded to pour them each a drink and hand round steaming mugs. Jack shook hands with the captain, a former Canadian navy officer who had spent a lifetime carrying out maritime patrols from the Arctic to the Gulf of Mexico, who had bounded down the stairs from the bridge to greet them. Jack would have time later to do the full rounds of the crew, many of them old friends and veterans of the first Seaquest, people with whom he shared a special bond.
The Greenlander woman sat down beside Lanowski at the computer workstation on the right-hand side of the room, positioning her laptop on the available corner of the desk and stacking her papers and books neatly on the floor to give the others space to stand. From the body language it was clearly an uneasy alliance, with Lanowski hunched directly in front of the main workstation screen surrounded by his papers, making no concession for her.
“I knew I should have brought my own hardware,” Lanowski grumbled.
“Someone should have given these things a trial run before they installed them.
I may as well crunch the numbers by hand.”
Jack raised his eyes at the woman and she forced a smile. “I’m interested in seabed biology; Lanowski does the simulations,” she said. “James paired us at the beginning of the project.”
She cast Macleod a malevolent glare, and he quickly turned to the others. “I’m sorry. I should have introduced you. This is Dr. Inuva Nannansuit, with the Geological Survey. She’s a native of Ilulissat, the town on the headland, so she grew up with the glacier in her backyard. She’s been a fantastic addition to the team.”
“So what have we got?” Jack said.
“It’s behind the stern, but the captain’s swinging the ship round to give us a broadside view to starboard. It’ll be a few minutes yet. We’re using the dynamic positioning system, as we don’t want water movement from the main screws to disturb what you’re about to see.”
“That berg out by the island, dead ahead of us now,” Maria said, pointing towards the ship’s bow. “It’s got a streak of black on the top. Is that ancient sediment from the glacier?”
“Well spotted, but no,” Macleod said. “If you look at the berg, it’s smooth and rounded, like a sculpture, quite different from the jagged and fissured bergs we saw when we flew over the fjord.”
“It must have rolled,” Costas said.
“Correct. We watched it happen last night. One of the most awesome sights you can imagine, a quarter of a million tons of ice doing a somersault in the water.
You don’t want to be anywhere near one of those babies when that happens.”
“Of course,” Maria exclaimed. “That smear is from the sea floor!”
“Exactly. When we arrived two weeks ago that berg was butted up against the threshold on the north side of the fjord, but we already knew from side-scan sonar that the submerged part had become eroded and lost much of its mass. It was only a matter of days before it would roll, and we kept well clear. Some of the bergs make it out that way, others get pushed upright over the sill. You can always tell from whether they look like Henry Moore sculptures or Disneyland ice castles.”
“You mean like that one,” Jack said.
They followed his gaze to starboard as a vast wall of ice came into view, about a quarter of a mile distant and clearly taller than the superstructure of the ship. It had the same contorted and jagged face as the front of the glacier, riven with veins of deep blue where meltwater had frozen inside crevasses, except for a wide flat area in the middle where it sloped down smoothly from the summit.
The berg was immense, at least a quarter of a mile across, and blocked a large stretch of the entrance to the fjord along the line of the underwater threshold.
They stared in awe until Macleod broke the silence. “Remember, three-quarters of that thing’s underwater. You’re looking at a cubic kilometre and a half of frozen water, at least a million and a half tons.”
Costas let out a low whistle. “That’d keep all the bars in the world in ice well into the next century.”
“A single day’s outlet from this glacier would be enough to supply New York with water for a year. Twenty million tons a day. We’re talking global impact here.”
“Tabular bergs of this size are pretty rare in the Arctic,” Inuva said. “We think it’s atmospheric warming again, resulting in the glacier receding to a point where larger fractures occur. It’s the biggest berg I’ve seen here in my lifetime.”
“Why hasn’t it broken up?” Costas said.
“It’s had one major calving event, where you can see that smooth face,”
Macleod said. “But the core’s unusually compact, solid glacial ice you’d crack only with explosives. It’s ideal for us. That face calved back to the core ice, so it’s relatively safe to work under. If you look closely you’ll see the drilling team in a couple of Zodiac inflatable boats out there now.”
“I don’t understand it.” Jeremy had been quietly absorbing everything since arriving on the ship, but had now recovered his normal inquisitiveness. “What’s to stop that thing tumbling over and crushing them?”
“That’s where the conditions really work in our favour,” Macleod said enthusiastically. “Without the pressure of the ice tongue behind them, bergs trapped on the sill are a lot safer to work on. The glacier itself is way too dangerous for coring, especially now that it’s flowing at such a rate. Bergs floating down the fjord are out of the question because they’re moving, and once they’re beyond the fjord they’re not only moving but are more liable to tumble. So a relatively fresh berg trapped on the sill is ideal for us. It’s a unique opportunity, but the window is closing fast.”
