Chapter Thirteen — Yaz | The Shape of Things

CICIMAR sent the packet back two days after the captain's advisory went out, which Yaz found genuinely touching in a way she didn't entirely expect — you file something through the proper channel expecting it to vanish into an inbox forever, and instead somebody on shore had apparently looked at Solá's Venezuela–Jamaica forward and thought, oh, while I have your attention, and attached a second file entirely, unprompted, about a site nobody aboard had asked them about at all.

"West of Australia," Amaleto said, reading off the cover sheet at the wardroom table, and Yaz had the camera up before anyone had decided this was a scene worth filming, purely on instinct, the same instinct that told her a dog was about to do something before the dog had committed to it.

The data itself was geodetic, not seismic — years of continuous GPS station readings, the kind of unglamorous background infrastructure that told you where the ground actually was rather than what it was doing, and it took William about four minutes of squinting at the header before he said, flatly, "This is a drift study."

"A drift what."

"The Australian continental plate," William said, already reaching for a second sheet, cross-referencing before he'd finished the first sentence, which Yaz had come to recognize as simply how his brain moved through a room. "It's the fastest-moving continental plate on Earth. Seven centimeters a year, give or take, northeast, and it doesn't sound like much until you understand it compounds — over enough years the country physically outran its own coordinate system. Every GPS device in Australia was quietly wrong by about a meter and a half by the time anyone got around to fixing it. They had to redraw the whole national datum. GDA94 to GDA2020. It's not obscure. It's public record. Surveyors talk about it the way pilots talk about a runway that used to be somewhere else."

"So the ground moved faster than the maps did," Yaz said, mostly to the camera, because it was too good a sentence not to say out loud twice.

"Right. Except—" William stopped, frowning at the second sheet, and Yaz watched him do the thing he did where a fact stopped being merely interesting and started being a problem. "Except this isn't just confirming the known rate. There's a note here about anomalous short-window acceleration, isolated to a handful of stations near the site in question, over roughly the same period as our own readings. It's small. It's within what a geodesist would probably call noise. But it's there."

"So it fits," Amaleto said, and Yaz caught, in her voice, something that hadn't been there in the trench, or the eddies, or even William's line — something closer to caution than excitement, and she understood why a half-beat later, watching Amaleto's face do the arithmetic out loud. "Or it doesn't. That's the honest answer. Plate motion this small, over a window this short, sits inside the same noise a hundred boring things could produce — a station getting rebuilt, a benchmark resurveyed, ordinary seasonal ground deformation. I have no way to tell the difference between 'this plate is being tugged the same way our basalt is' and 'this plate has always moved fast and a handful of instruments had a noisy month.' Nobody does. Not from this data. Possibly not from any data anyone could collect on a timescale shorter than years."

"So it's a real anomaly you can't test," Yaz said.

"It's a real anomaly I can't test yet," Amaleto said, with an emphasis that made clear she'd noticed the distance between those two sentences and had chosen, deliberately, to live on the second side of it.

Heath, across the table, said nothing at all, which Yaz noticed more than she noticed most of what he did say — no analogy reaching for the gap, no offer of a bridge, just a long look at the sheet and a silence that read, for once, less like restraint after a warning and more like a man who genuinely didn't have anything to add to a piece of data that admitted two full stories and gave you no way to choose between them.

She thought about it for most of the afternoon, in the loose, unfocused way she thought about things she wasn't actually trying to think about, and found herself, a little after dinner, sitting with the camera in her bunk instead of on deck, which was where she generally saved the parts of the day she hadn't figured out yet.

"Storm's real," she told the lens. "Trench is real. Line's real, apparently, God help us all. And now there's a continent on the other side of the planet that might be getting tugged the same way, or might just be doing what it's always done a little louder than usual for a month, and nobody — not Amaleto, not William, not the actual professional geodesists who get paid real money to know this stuff — nobody can tell you which. That's not a cliffhanger. A cliffhanger resolves eventually. This is just — the answer genuinely isn't in yet, and it might not be in for years, and everybody has to go to bed tonight anyway not knowing."

She turned the camera slightly, caught herself in the little screen fold-out, and kept going, because this was the part she actually wanted to say and had been circling for the last hour without quite landing on it.

"I have this recurring dream. Chase dream — there's probably an actual term, some very serious person's written a grant about it. I'm running after something. A bus, a person, one time, a goat, don't ask. And I'm not slow, I want that on the record, I am moving. It's that the gap doesn't care how fast I go. I close it by exactly as much as I speed up, every single time, like the whole dream's doing math behind my back just to keep the distance even no matter what I try. You wake up out of breath from a dream where you never once lost ground and never once caught anything either." She let that sit a second. "Today felt like the dream. Not the bad kind. Just — the kind where you finally understand the running was never going to be the part that ended it."

She clicked the camera off before she could decide whether that was too much to leave in, and left it in anyway.

[Cordero, personal log, day thirteen, 22:30]

Australia data in. Real anomaly, real ambiguity, no way to settle it that anyone aboard this ship — or possibly anyone anywhere — currently has access to. Logging it as exactly that: unresolved. Not "pending." Unresolved has a different shape and I want the shape on the record.

Heath didn't say anything today, which might be the single most unsettling thing that's happened all week, and I include the storm and the trench and William's terrifying little chart in that comparison.

Told the camera about the chase dream. Might cut it. Probably won't.

Cordero, out.
