Waela marked their descent past eighty-five meters and called it out. She leaned close to the screen which displayed the lagoon's nearest wall of encaging kelp. The long strands angled down into darkness with an occasional black tentacle reaching out toward the sub. The external dive lights played green shadows on the pale kelp, revealing small dark extrusions, bubbles whose purpose remained undiscovered. Farther down, such bubbles played their bright patterns of light.
The water around the kelp strand and in the upper lagoon was aswarm with darting and slow-moving shapes, some with many eyes and some with none. Some were thin and worm-like, some fat and ponderous with long fleshy fins and toothless gaping jaws. None had ever been known to attack Shipmen and it was thought they lived in symbiosis with the kelp. Taking them for specimens aroused the kelp to violence and when they were removed from the sea, they melted so rapidly that mobile labs appeared to be the only way to examine them. But mobile labs did not survive long here.
Farther down, Waela knew, there would be fewer and fewer of these creatures. Then the sub would enter the zone of crawlers, things which moved along the kelp and across the sea floor. A few large swimmers there, but crawlers dominated.
On the flight out to the lagoon, Waela had kept herself busy, fearing that she might break down when the moment came to make another dive. It had helped to recall the strong construction of this sub, but the actual moment of the dive had loomed ahead, mingled with a return to dark memories of terror. Colony's last dive had been a disaster. The sub had been seventy meters long, studded with knives and cutters. It had cost Colony a terrible toll in lives to transport it across The Egg's undulating plains to the one area on the south coast where they could skid the sub into a wave-washed bay of kelp. She had been one of the nine on the crew, the only survivor.
For a time, they had thought sheer size and weight would bring them success. Water doors were opened remotely and stuffed with kelp specimens. But the kelp's cable-strands released themselves from the rocks on the seafloor and, tendrils waving, swept over the sub. There seemed no end to the attack. More and more kelp came at them, wrapping around the sub, overwhelming the cutters by weight of numbers, drawing them deeper and deeper while tendrils probed for any weak point. Leaves blinded their external sensors. Static crackled in their communications system. They were blind and dumb. Then water had jetted into the hull near a hatch, a stream so strong it cut the flesh in its path.
Thinking about those moments made Waela's breath come faster. She had been operating a cutter, her station a plaz bubble extruded from the hull. Leaves covered the bubble except for straining strands of kelp trying to crush the sub. Through the crashing static in her earphones, she had heard a crewmate describe the water jet cutting one of their companions in half. Abruptly, a warping of the hull and the explosive shift of pressure within the sub had blasted her bubble free. It shot out and clear of the blinding leaves, then upward as the kelp spread aside to permit her passage. She had never been able to explain that phenomenon. The kelp had opened a way to the surface for her!
Once into the glare of double-day side, she had forced open the hatch, dived clear to an undulant sea covered by broad fans of kelp leaves. She remembered touching the leaves, fearing them and needing them to support her; they were a pale green cushion which dampened the waves. Then she had felt a tingling all through her body. Her mind had been invaded by wild images of demons and humans locked in death struggles. She remembered screaming, swallowing salty water and screaming. Within seconds, the images overwhelmed her and she rolled across a kelp leaf unconscious.
An observation LTA had snatched her from the sea. She had spent many diurns recovering, awakening to acclaim because she had proved that the kelp not only was dangerous because of its physical abilities, but that its hallucinogenic capacity worked havoc when enough of it contacted enough of a Shipman's body in a liquid medium.
"Is something wrong, Waela?"
That was Panille staring at her, concerned by her introspection.
"No. We're leaving the active surface waters. We'll begin to see the lights soon."
"You've been down here before, they tell me."
"Yes."
"We'll be safe as long as we don't threaten the kelp," Thomas said. "You know that."
"Thanks."
"The records say that attempts to establish a shoreside harvester were defeated when the kelp actually came ashore to attack," Panille said.
"People and machines were snatched from the shore, yes," she said. "The people drowned and were thrown back. Machines just disappeared."
"Then why won't it attack us here?"
"It never has when we just come down and observe."
Saying this helped her restore a measure of calm. She returned to observation of sensors and telltales.
Panille peered over his shoulder at her screen, saw the angled strands of kelp, the fluting leaves and the curious bubble extrusions which reflected starbursts from the sub's dive lights. When he looked up past the ladder to the top hatch, he could see the luminous circle of the lagoon's surfac...receding moon populated by the darting shapes of the creatures who shared the sea with the kelp.
The lagoon was a place of magic and mystery with a beauty so profound he felt thankful to Ship just to have seen it. The kelp strands were pale gray-green cables, thicker than a Shipman's torso in places. They reached up from darkness into the distant mercuric pool of light overhead.
Light reaches for stars and, seeing the stars, fears to grasp them, floats in wonder. Oh, stars, you burn my mind.
The kelp aimed itself at Rega, the only sun in their sky at the moment. Alki would join Rega later. Even under clouds, the kelp aligned itself perpendicular to the passage of a sun. When two suns were present, this tropism adjusted to the radiation balance. It was a precise adjustment.
Panille thought about this, reviewing what he had learned from Ship. These were observations which perilous ventures into the sea had gleaned. Sparse information, and nowhere as intense as what he learned by being here. He knew some of the things he would see at the bottom: kelp tendrils wrapped around and through large rocks. Crawling creatures and burrowing ones. Slow currents, drifting sediments. Lagoons were ventilators, passages for exchange between surface and bottom waters. Near the surface, they provided light for creatures other than kelp.
The lagoons were cages.
"These lagoons are where the kelp engages in aquaculture," he said.
Thomas blinked. That was so close to his own surmise about how kelp fitted into the sea system that he wondered if Panille had been eavesdropping on his thoughts.
Is Ship talking to him even now?
Panille's words fascinated Waela. "You think the kelp follows a conscious pain?"
"Perhaps.
To Thomas, the poet's words pulled a veil from the kelp domain. He began to sense the sea in a different way. Here was rich living space free of Pandora's other dangerous demons. Was it right then to rid the sea of kelp? He knew it could be done - disrupt the ecosystem, break the internal chain of the kelp's own life. Was that the decision of Oakes and Lewis?
"The lights!" Panille said. "Ohhh, yes."
They had reached the dark zone where the sub's external sensors began to pick up the flickering lights. Jewels danced in the blackness beyond the range of the dive lights - tiny bursts of colo.... red, yellow, orange, green, purpl.... There appeared to be no pattern to them, just bursts of brilliance which dazzled the awareness.
"Bottom coming up," Waela said.
Panille, every sense alert, shot a glance at her screen. Yes - the bottom appeared to be moving while they remained stationary. Coming up.
