The Ocean of the Blind Page 2

  The price, of course, was that it took six days to go up to the surface. The pressure difference between the 300 atmospheres at the bottom of the sea and the half standard at the surface station meant a human wouldn't just get the bends if he went up quickly—he'd literally explode. There were other dangers, too. All the crew at Hitode took a regimen of drugs to ward off the scary side effects of high pressure.

  With his APOS running (though for now its little computer was sensible enough to simply feed him air from the room outside), Rob pulled on his three layers of gloves, buckled on his fins, put on his weight belt, switched on his shoulder lamp, and then crouched on the edge of the moon pool to let himself tumble backward into the water. It felt pleasantly cool, rather than lethally cold, and he bled a little extra gas into his suit to keep him afloat until Henri could join him.

  He gave the drones instructions to follow at a distance of four meters, and created a little window on his faceplate to let him watch through their eyes. He checked over the camera clamped to his shoulder to make sure it was working. Everything nominal. It was 0120 now. Where was Henri?

  Kerlerec lumbered into view ten minutes later. In the bulky stealth suit he looked like a big black toad. The foam cover of his faceplate was hanging down over his chest, and Rob could see that he was red and sweating. Henri waddled to the edge of the pool and fell back into the water with an enormous splash. After a moment he bobbed up next to Rob.

  “God, it is hot in this thing. You would not believe how hot it is. For once I am glad to be in the water. Do you have everything?"

  “Yep. So how are you going to use the camera in that thing? Won't it spoil the whole stealth effect?"

  “I will not use the big camera. That is for you to take pictures of me at long range. I have a couple of little cameras inside my helmet. One points forward to see what I see, the other is for my face. Link up."

  They got the laser link established and Rob opened two new windows at the bottom of his faceplate. One showed him as Henri saw him—a pale, stubbly face inside a bubble helmet—and the other showed Henri in extreme close-up. The huge green-lit face beaded with sweat looked a bit like the Great and Powerful Oz after a three-day drunk.

  “Now we will get away from the station and try out your sonar on my suit. You will not be able to detect me at all."

  Personally Rob doubted it. Some Russian had made a cool couple of million Euros selling Henri and his sponsors at ScienceMonde a failed prototype or just a fake.

  The two of them descended until they were underneath Hab One, only a couple of meters above the seafloor. The light shining down from the moon pool made a pale cone in the silty water, with solid blackness beyond.

  Henri led the way away from the station, swimming with his headlamp and his safety strobe on until they were a few hundred meters out. “This is good,” he said. “Start recording."

  Rob got the camera locked in on Henri's image. “You're on."

  Henri's voice instantly became the calm, friendly but all-knowing voice of Henri Kerlerec, scientific media star. “I am here in the dark ocean of Ilmatar, preparing to test the high-tech stealth diving suit which will enable me to get close to the Ilmatarans without being detected. I am covering up the faceplate with the special stealth coating now. My cameraman will try to locate me by sonar. Because the Ilmatarans live in a completely dark environment, they are entirely blind to visible light, so I will leave my safety strobe and headlamp on."

  Rob opened up a window to display sonar images and began recording. First on passive—his computer could build up a vague image of the surroundings just from ambient noise and interference patterns. No sign of Henri, even though Rob could see his bobbing headlamp as he swam back and forth ten meters away.

  Not bad, Rob had to admit. Those Russians know a few things about sonar baffling. He tried the active sonar. The seabottom and the rocks flickered into clear relief, an eerie false-color landscape where green meant soft and yellow meant hard surfaces. The ocean itself was completely black on active. Henri was a green-black shadow against a black background. Even with the computer synthesizing both the active and passive signals, he was almost impossible to see.

  “Wonderful!” said Henri when Rob sent him the images. “I told you: completely invisible! We will edit this part down, of course—just the sonar images with me explaining it in voiceover. Now come along. We have a long trip ahead of us."

  The Bitterwater Company are waking up. Longpincer's servants scuttle along the halls of his house, listening carefully at the entrance to each guest chamber and informing the ones already awake that a meal is ready in the main hall.

  Broadtail savors the elegance of having someone to come wake him when the food is ready. At his own house, all would starve if he waited for his apprentices to prepare the meals. He wonders briefly how they are getting along without him. The three of them are reasonably competent, and can certainly tend his pipes and crops without him. Broadtail does worry about how well they can handle an emergency—what if a pipe breaks or one of his nets is snagged? He imagines returning home to find chaos and ruin.

  But it is so very nice here at Longpincer's house. Mansion, really. The Bitterwater vent isn't nearly as large as Continuous Abundance or the other town vents, but Longpincer controls the entire flow. Everything for ten cables in any direction belongs to him. He has a staff of servants and hired workers. Even his apprentices scarcely need to lift a pincer themselves.

  Broadtail doesn't want to miss the meal. Longpincer's larder is as opulent as everything else at Bitterwater. As he crawls to the main hall he marvels again at the thick growths on the walls and floor. Some of his own farm pipes don't support this much life. Is it just that Longpincer's large household generates enough waste to support lush indoor growth? Or is he rich enough to pipe some excess vent water through the house itself? Either way it's far more than Broadtail's chilly property and tepid flow rights can achieve.

  As he approaches the main hall Broadtail can taste a tremendous and varied feast laid out. It sounds as if half a dozen of the Company are already there; it says much for Longpincer's kitchen that the only sounds Broadtail can hear are those of eating.

  He finds a place between Smoothshell and a quiet individual whose name Broadtail can't recall. He runs his feelers over the food before him and feels more admiration mixed with jealousy for Longpincer. There are cakes of pressed sourleaf, whole towfin eggs, fresh jellyfronds, and some little bottom-crawling creatures Broadtail isn't familiar with, neatly impaled on thorns and still wiggling.

  Broadtail can't recall having a feast like this since he inherited the Northslope property and gave the funeral banquet for old Flatbody. He is just reaching for a third jellyfrond when Longpincer clicks loudly for attention from the end of the hall.

  “I suggest a small excursion for the Company,” he says. “About ten cables beyond my boundary stones upcurrent is a small vent, too tepid and bitter to be worth piping. I forbid my workers to drag nets there, and I recall finding several interesting creatures feeding at the vent. I propose swimming there to look for specimens."

  “May I suggest applying Sharpfrill's technique for temperature measurement to those waters?” says Smoothshell.

  “Excellent idea!” cries Longpincer. Sharpfrill mutters something about not having his proper equipment, but the others bring him around. They all finish eating (Broadtail notices several of the company stowing delicacies in pouches, and grabs the last towfin egg to fill his own), and set out for the edge of Longpincer's property.

  Swimming is quicker than walking, so the party of scholars cruise at just above net height. At that height Broadtail can only get a general impression of the land below, but it all seems neat and orderly—a well-planned network of stone pipes radiating out from the main vent, carrying the hot, nutrient-rich water to nourish thousands of plants and bacteria colonies. Leaks from the pipes and the waste from the crops and Longpincer's household feeds clouds of tiny swimmers, which in turn attract
larger creatures from the cold waters around. Broadtail notes with approval the placement of Longpincer's nets, in staggered rows along the prevailing current. With a little envy he estimates that Longpincer's nets probably produce as much wealth as his own entire property.

  Beyond the boundary stones the scholars instinctively gather into a more compact group. There is less conversation and more careful listening and pinging. Longpincer assures them that he allows no bandits or scavengers around his vent, but even he pings behind them once or twice, just to make sure. But all anyone can hear are a few wild children, who flee quickly at the approach of adults.

  Henri and Ron didn't talk much on the way to the vent community. Both of them were paying close attention to the navigation displays inside their helmets. Getting around on Ilmatar was deceptively easy: take a bearing by inertial compass, point the impeller in the right direction, and off you go. But occasionally Ron found himself thinking about just how hard it would be to navigate without electronic help. The stars were hidden by a kilometer of ice overhead, and Ilmatar had no magnetic field worth speaking of. It was barely possible to tell up from down—if you had your searchlights on and could see the bottom and weren't enveloped in a cloud of silt—but maintaining a constant depth depended entirely on watching the sonar display and the pressure gauge. A human without navigation equipment on Ilmatar would be blind, deaf, and completely lost.

  At 0500 they were nearing the site. “Passive sonar only,” said Henri. “And we must be as quiet as possible. Can you film from a hundred meters away?"

  “It'll need enhancement and cleaning up afterward, but yes."

  “Good. You take up a position there—” Henri gestured vaguely into the darkness.

  “Where?"

  “That big clump of rocks at, let me see, bearing one hundred degrees, about fifty meters out."

  “Okay."

  “Stay there and do not make any noise. I will go on ahead toward the vent. Keep one of the drones with me."

  “Right. What are you going to do?"

  “I will walk right into the settlement."

  Shaking his head, Rob found a relatively comfortable spot among the stones. While he waited for the silt to settle, he noticed that this wasn't a natural outcrop—these were cut stones, the remains of a structure of some kind. Some of the surfaces were even carved into patterns of lines. He made sure to take pictures of everything. The other xeno people back at Hitode would kill him if he didn't.

  Henri went marching past in a cloud of silt. The big camera was going to be useless with him churning up the bottom like that, so Rob relied entirely on the drones. One followed Henri about ten meters back, the second was above him looking down. The laser link through the water was a little noisy from suspended particulates, but he didn't need a whole lot of detail. The drone cameras could store everything internally, so Rob was satisfied with just enough sight to steer them. Since he was comfortably seated and could use his hands, he called up a virtual joystick instead of relying on voice commands or the really irritating eye-tracking menu device.

  “Look at that!” Henri called suddenly.

  “What? Where?"

  Henri's forward camera swung up to show eight Ilmatarans swimming along in formation, about ten meters up. They were all adults, wearing belts and harnesses stuffed with gear. A couple carried spears. Ever since the first drone pictures of Ilmatarans, they had been described as looking like giant lobsters, but watching them swim overhead, Rob had to disagree. They were more like beluga whales in armor, with their big flukes and blunt heads. Adults ranged from three to four meters long. Each had a dozen limbs folded neatly against the undersides of their shells: walking legs in back, four manipulators in front, and the big praying-mantis pincers on the front pair. They also had raspy feeding tendrils and long sensory feelers under the head. The head itself was a smooth featureless dome, flaring out over the neck like a coal-scuttle helmet—the origin of the Ilmatarans’ scientific name Salletocephalus structor. Henri's passive microphones picked up the clicks and pops of the Ilmatarans’ sonar, with an occasional loud ping like a harpsichord note.

  The two humans watched as the group soared over Henri's head. “What do you think they're doing?” asked Rob when they had passed.

  “I am not sure. Perhaps a hunting party. I will follow them."

  Rob wanted to argue, but knew it was pointless. “Don't go too far."

  Henri kicked up from the bottom and began to follow the Ilmatarans. It was hard for a human to keep up with them, even when wearing fins. Henri was sweaty and breathing hard after just a couple of minutes, but he struggled along. “They are stopping,” he said after ten minutes, sounding relieved.

  The Ilmatarans were dropping down to a small vent formation, which Rob's computer identified as Maury 3b. Through the drone cameras Rob watched as Henri crept closer to the Ilmatarans. At first he moved with clumsy stealth, then he abandoned all pretense and simply waded in among them. Rob waited for a reaction, but the Ilmatarans seemed intent on their own business.

  A rock is missing. Broadtail remembers a big chunk of old shells welded together by ventwater minerals and mud, just five armspans away across-current. But now it's gone. Is his memory faulty? He pings again.

  There it is, just where it should be. Odd. He goes back to gathering shells.

  “—you hear me? Broadtail!” It is Longpincer. He appears out of nowhere just in front of Broadtail, sounding alarmed.

  “I'm here. What's wrong?"

  “Nothing,” says Longpincer. “My own mistake."

  “Wait. Tell me."

  “It's very odd. I remember hearing you clattering over the rocks, then silence. I recall pinging and sensing nothing."

  “I remember a similar experience—a rock seeming to disappear and then appear again."

  Smoothshell comes up. “What's the problem?” After they explain she asks, “Could there be a reflective layer here? Cold water meeting hot does that."

  “I don't feel any change in the water temperature,” says Longpincer. “The current here is strong enough to keep everything mixed."

  “Let's listen,” says Broadtail. The three of them stand silently, tails together, heads outward. Broadtail relaxes, letting the sounds and interference patterns of his surroundings create a model in his mind. The vent is there, rumbling and hissing. Someone is scrabbling up the side—probably Sharpfrill with his jars of temperature-sensitive plants. Roundhead and the quiet person are talking together half a cable away, or rather Roundhead is talking and his companion is making occasional polite clicks. Two others are swishing nets through the water upcurrent.

  But there is something else. Something moving nearby. He can't quite hear it, but it blocks other sounds and changes the interference patterns. He reaches over to Smoothshell and taps on her leg. “There is a strange effect in the water in front of me, moving slowly from left to right."

  She turns and listens that way while Broadtail taps the same message on Longpincer's shell. “I think I hear what you mean,” she says. “It's like a big lump of very soft mud, or pumice stone."

  “Yes,” Broadtail agrees. “Except that it's moving. I'm going to ping it now.” He tenses his resonator muscle and pings as hard as he can, loud enough to stun a few small swimmers near his head. All the other Company members about the vent stop what they are doing.

  He hears the entire landscape in front of him—quiet mud, sharp echoes from rocks, muffled and chaotic patterns from patches of plants. And right in the center, only a few armspans in front of him, is a hole in the water. It's big, whatever it is: almost the size of a young adult, standing upright like a boundary marker.

  Henri was completely gonzo. He was rattling off narration for the audience completely off the top of his head. Occasionally he would forget to use his media star voice and give way to an outburst of pure cackling glee. Rob was pretty excited, too, watching through the cameras as Henri got within arm's reach of the Ilmatarans.

  “Here we see a grou
p of Ilmatarans gathering food around one of the seabottom vents. Some are using hand-made nets to catch fish, while these three close to me appear to be scraping algae off the rocks."

  “Henri, you're using Earth life names again. Those aren't fish, or algae either."

  “Never mind that now. I will dub in the proper words later if I must. The audience will understand better if I use words they understand. This is wonderful, don't you think? I can pat them on the backs if I want to!"

  “Remember, no contact."

  “Yes, yes.” Back into his narrator voice. “The exact nature of Ilmataran social organization is still not well understood. We know they live in communities of up to a hundred individuals, sharing the work of food production, craft work, and defense. The harvest these bring back to their community will be divided among all."

  “Henri, you can't just make stuff up like that. Some of the audience are going to want links to more info about Ilmataran society. We don't know how they allocate resources."

  “Then there is nothing to say that this is untrue. Robert, people do not want to hear that aliens are just like us. They want wise angels and noble savages. Besides, I am certain I am right. The Ilmatarans behave exactly like early human societies. Remember I am an archaeologist by training. I recognize the signs.” He shifted back into media mode. “Life is difficult in these icy seas. The Ilmatarans must make use of every available source of food to ward off starvation. I am going to get closer to these individuals so that we can watch them at their work."

  “Don't get too close. They might be able to smell you or something."

  “I am being careful. How is the picture quality?"

  “Well, the water's pretty cloudy. I've got the drone providing an overhead view of you, but the helmet camera's the only thing giving us any detail."
