Breath Ratio

Predawn, the pier was all angles and salt. The air smelled of metal and warning. Luc entered the lab, heart still beating to the rhythm of the storm, the echo of the sea’s breath heavy in his chest, metal giving way to the clean brightness he trusted: benches matte, coils nested, cables exact. The storm had stirred silt, making his hydrophone plots look fevered.

He powered the rack in sequence—battery, preamp, interface, monitor. Green lines rose from black. The smell beneath disinfectant was ozone, proof that machines lived. He dried the first hydrophone slowly; salt leaves clean only for patience. The dome caught light and shone.

Trust process, not self. The storm was brief. The sea was already smoothing. He let the plots draw straight lines again.

Denver’s email arrived before sunrise: Tank A: Acoustic Drift. Familiar file trees. Beneath mechanical hiss something waited—too round for pumps, too patient for artifact. He labeled it LFN – pending source, not breath.

Another message blinked: Assist Request—Cetacean Transport, Mountain Facility to Coast. He replied before thinking: Available. Able to travel within 36 hours. He could have written I want to help. He didn’t trust that verb. Control was easier than courage.

He listened once more. The hum in Denver’s logs pulsed at eighteen cycles—a living pattern misfiled as noise. He wrote: Stress-induced tonality.

He hadn’t spoken to Marti since she took the Denver post. He leaned back, thought of her laugh dissolving in fog. The memory carried her scent—salt, lavender, wet rope—so vivid it startled him. He typed and deleted the same line twice: Do not confuse clarity with kindness. Numbers moved toward completion, mercy disguised as math. His hand trembled once. He blamed caffeine, not memory.

The transport ship left harbor at dusk, its hull working the chop like a rib cage. Luc watched the feed lines climb—green over blue. Numbers meant breath.

The whale—designated Specimen 12-F, though some crew whispered a name—filled the tank like gravity. Each exhale caught deck light and vanished. Luc logged oxygen drift: .04, acceptable.

Kira appeared beside him, clipboard in hand. “Didn’t expect this much noise,” she said.

“It’s the pumps.”

“Feels like she’s humming back.”

He didn’t answer.

The storm came late. Pressure fell. Rain slanted. Lights flickered. The data plots went feral. “Secure pumps!” he yelled. Oxygen feed fluctuated. Manual control, valve over-tightened, graph plunging. The whale rolled, her hum deepening into voice.

Kira braced against the rail. “She’s panicking!”

“Maintain ratio!”

Her eyes met his, wide and steady. “Maybe she’s scared, not malfunctioning.”

He steadied the numbers—9.6 ppm—and matched his breathing. Control returned. His pulse matched the gauge, proof he was alive only by calibration.

By midnight, calm. Kira handed him coffee, steam ghosting between them. “She’s been humming since the storm.”

“Pressure differential.”

“Maybe she just wants home.”

“She’ll adjust once she’s back in saltwater.”

He almost believed it.

She lingered. “You used to work with Dr. Leduc, didn’t you?”

He nodded once.

“She left you, right?”

Luc pretended to check the readings. “We were better in data than in person.”

He didn’t reply further. Instead, he wrote: Stable. Within tolerance. Minimal intervention. Then added: Resonance increasing—source uncertain. The line looked like a confession.

He didn’t need the past to explain itself; the present was loud enough.

***

The sea turned glassy. Luc sat alone at the aft console, red light breathing across his hands. The hum had softened but persisted, running through hull, air, thought.

He opened a new voice file: Operator: Luc Arnaud. Not diagnostic. Before he spoke, his tablet blinked—a message from Denver. Marti’s voice filled the small cabin, the same recording from the call she made before leaving: static and tide between syllables. You still there, Marti? he heard himself answer, a ghost of the conversation from memory. The overlap made the air feel thin. Then he began recording.

“She’s still breathing evenly. Eighteen under, six out.” Constancy felt like mercy—until it didn’t.

He layered the Denver file under his voice; machine and confession merged. “Marti… I should’ve said your name.”

He admitted it—the meeting, the nod, the fear of being seen as more than colleagues. “I thought protecting us meant silence. But silence wrote me in as the author.”

He stopped. Wanted to delete, wanted to send. Did neither.

He listened to the whale’s breath through the hull—slow, steady, clinical—and whispered the count like a prayer: one, two, three, release. His breath caught; he noticed and let it stay. The hum changed key. Maybe current, maybe forgiveness.

He paused the log, listening to the echo of Marti’s voice fading under engine noise—a phantom dialogue overlapping time itself. The realization steadied him: while she’d spoken into the past, he was speaking into the same moment from a different shore.

Kira entered quietly, holding two mugs. “Couldn’t sleep,” she said. “You look like you couldn’t either.” Her tone softened. “I don’t chase ghosts, Luc. But I know when someone’s still holding one.”

He didn’t respond. She set a mug beside him and stayed until the hum became silence between them. When she left, he almost called her back—almost.

He looked at his reflection in the dark glass of the monitor and realized steadiness was the only way he knew how to feel. The thought embarrassed him. He let it stay. 

In his log he wrote: Variable: human error—persistent. Status: acknowledged. Below it: Truth sounds like this when you don’t edit it.

He sealed the file. The act didn’t clean anything; it just made the noise honest.

By the third day the ocean felt rehearsed, too calm to trust. The whale had stopped calling. Silence in a cetacean isn’t peace; it’s retreat. Luc let the crew believe otherwise.

He went below, into turbine heat. The ship’s pulse thudded through his boots, nearly indistinguishable from the specimen’s faint hum. He touched the railing and felt its tremor match his own pulse—unwanted proof of connection.

“She’s not eating,” said Kira.

“She’s conserving energy.”

“Maybe she’s refusing.”

“Refusal’s a human thing.”

“You sure?”

She held his gaze longer—soft, assessing. “Sophie said Marti called you the quiet current. That you always pulled but never surfaced.”

Luc flinched. “She talks to Sophie?”

“Still does.”

“Of course she does.”

A pressure shift rolled through the hull. The engines prayed in the specimen’s key.

“If we’re saving her,” Kira asked, “why does it sound like we’re killing her?”

He pulled his recorder. “Capturing overlap.”

“For what?”

“For record.”

“Sometimes record’s just another word for keeping what hurts,” she murmured.

The air thickened. Every bolt sang.

“It’s the same tone as the whale’s,” she said.

“Sympathetic resonance.”

“Sympathy,” she repeated. “That what you call it?”

He marked the recording. Maybe the signal was the contamination.

He remembered Marti saying, The ocean remembers what we do to it. Even silence is archive. He’d called it metaphor. Not anymore.

The hum became heartbeat; alarms split it open. Crew scrambled. Luc stayed, watching the waveform bloom into symmetry—each human pulse mirrored by a mechanical one. Equal. Complicit.

He set the recorder on the deck, left it running. Let the system hear itself. His hand shook before he pulled it away.

By dusk the sea looked normal again—the kind of normal that erases memory. Kira asked, “You got what you needed?”

“Not sure.”

She looked out at the water. “She hoped you’d stop her.”

He felt the words more than heard them—a pulse beneath the hum.

“Maybe she was right to leave,” he said finally. “I’d have turned her world into data.”

“Maybe,” Kira answered, quieter now. “But that doesn’t make it hurt less.”

He looked at her then, really looked, and saw the same exhaustion he carried. “You’re tired too.”

“Always,” she said. “Doesn’t mean we stop.”

Her mouth softened, a hint of thanks.

He nodded once—connection small, unedited.

The air carried a trace of lavender, faint as a thought. It made him shiver.

Below, the water pulsed—a metronome for every guilt.

***

Dawn thinned the fog to silver. The ship slowed; engines dimmed from prayer to breath. Crew lined the rail as gates opened. Water moved like memory. The specimen slid out, hovered, then vanished.

Luc watched monitors: pulse dissolving into ocean. He kept recording—witness as his last control.

“She’s out of range,” Kira said.

“Not yet.”

A final flicker, then nothing. “Now.”

Not grief exactly—something slower, denser. Complicity finding its final weight.

He dictated: Transfer complete. All systems unstable. He left the tremor in his voice, the machinery still humming her frequency.

Kira touched the rail beside him. “She’s gone. You don’t have to keep following her.”

“I do.”

“I figured.”

“She’d tell you to stop chasing ghosts,” Kira said.

“She would,” he admitted.

“Then maybe listen—for once.”

He almost laughed. “I’m trying.”

He pulled the confession log from his pocket—hesitated—then set it beside the recorder. “If she asks, tell her I sent it.”

Kira’s expression softened. “You finally did something that isn’t measurement.”

“Maybe it still is,” he said. “But it’s something.”

He placed the recorder on the deck grating—no tags, no annotations—just sound left open to whatever came next. The drive would fill with hours of useless noise: wind, diesel, waves. Everything humans make and call natural.

“What if it fills?” Kira asked.

“Then it’s full.”

Light skimmed the horizon. He took one measured breath—the kind before diving or confessing. One, two, three, release. He caught the tremor halfway through and let it stay. The sea breathed back once, faintly, in rhythm.

He typed the final line:

Operator’s note: No absolution. Just breath. Just proof.

He stood for a long moment, watching fog lift and reform, the sea rewriting itself with each wave. Then he stepped back and let it. The recorders kept running. Someone, someday, would hear.
