The Year's Best Science Fiction, Vol. 20

“Perhaps it would. But it would also make us unforgivably late for our target.” Mina dropped the tone of her voice, making an obvious effort to sound reasonable. “Look-I understand your curiosity. I feel it as well. But the chances are it was either a statistical fluke or part of a global event everyone else will have had a much better chance to study. Either way we can’t contribute anything useful, so we might as well just forget about it.” She rubbed at the marks on her forearm, tracing the paisley-patterned barbs and whorls of glowing colouration. “And I’m tired, and we have several busy days ahead of us. I think we just need to put this one down to experience, all right?”

“Fine,” Naqi said.

“I’m sorry, but I just know we’d be wasting our time.”

“I said fine.” Naqi stood up and steadied herself on the railing that traversed the length of the airship’s back.

“Where are you going?”

“To sleep. Like you said, we’ve got a busy day coming up. We’d be fools to waste time chasing a fluke, wouldn’t we?”

An hour after dawn they crossed out of the dead zone. The sea below began to thicken with floating life, becoming soupy and torpid. A kilometre or so farther in and the soup showed ominous signs of structure: a blue-green stew of ropy strands and wide kelplike plates. They suggested the floating, half-digested entrails of embattled sea monsters.

Within another kilometre the floating life had become a dense vegetative raft, stinking of brine and rotting cabbage. Within another kilometre of that the raft had thickened to the point where the underlying sea was only intermittently visible. The air above the raft was humid, hot and pungent with microscopic irritants. The raft itself was possessed of a curiously beguiling motion, bobbing and writhing and gyring according to the ebb and flow of weirdly localised current systems. It was as if many invisible spoons stirred a great bowl of spinach. Even the shadow of the airship-pushed far ahead of it by the low sun-had some influence on the movement of the material. The Pattern Juggler biomass scurried and squirmed to evade the track of the shadow, and the peculiar purposefulness of the motion reminded Naqi of an octopus she had seen in the terrestrial habitats aquarium on Umingmaktok, squeezing its way through impossibly small gaps in the glass prison of its tank.

Presently they arrived at the precise centre of the circular raft. It spread away from them in all directions, hemmed by a distant ribbon of sparkling sea. It felt as if the airship had come to rest above an island, as fixed and ancient as any geological feature. The island even had a sort of geography: humps and ridges and depressions sculpted into the cloying texture of layered biomass. But there were few islands on Turquoise, especially at this latitude, and the Juggler node was only a few days old. Satellites had detected its growth a week earlier, and Mina and Naqi had been sent to investigate. They were under strict instructions simply to hover above the island and deploy a handful of tethered sensors. If the node showed any signs of being unusual, a more experienced team would be sent out from Umingmaktok by high-speed dirigible. Most nodes dispersed within twenty to thirty days, so there was always a sense of urgency. They might even send trained swimmers, eager to dive into the sea and open their minds to alien communion. Ready to-as they said- ken the ocean.

But first things first. Chances were this node would turn out to be interesting rather than exceptional.

“Morning,” Mina said, when Naqi approached her. Mina was swabbing the sensor pod she had reeled in earlier, collecting green mucous that had adhered to its ceramic teardrop. All human artifacts eventually succumbed to biological attack from the ocean, although ceramics were the most resilient.

“You’re cheerful,” Naqi said, trying to make the statement sound matter-of-fact rather than judgmental.

“Aren’t you? It’s not everyone gets a chance to study a node up this close. Make the most of it, sis. The news we got last night doesn’t change what we have to do today.”

Naqi scraped the back of her hand across her nose. Now that the airship was above the node she was breathing vast numbers of aerial organisms into her lungs with each breath. The smell was redolent of ammonia and decomposing vegetation. It required an intense effort of will not to keep rubbing her eyes more raw than was already the case. “Do you see anything unusual?”

“Bit early to say.”

“So that’s a ‘no,’ then.”

“You can’t learn much without probes, Naqi.” Mina dipped a swab into a collection bag, squeezing tight the plastic seal. Then she dropped the bag into a bucket between her feet. “Oh, wait. I saw another of those swarms, after you’d gone to sleep.”

“I thought you were the one complaining about being tired.”
