Deflection Protocols

Could two hundred tons of displacement be bluffed by fifty amps of copper wire?

Suometar did not wait for the hydrophone rack to run the probability. The green waterfall screen painted the truth in descending streaks of light: two massive biological plumes slicing through the outer thermocline at thirty knots, their courses converging on the station's intake basin like harpoons drawn to a lantern.

Beside the console, Kaarle-alt dropped to all fours. The wet concrete slapped against his palms as his spine arched, vertebrae ridging beneath translucent gray skin. His dorsal spines flared rigid, shivering with a violent, forty-hertz tremor that rattled the loose cotter pins across the bench. He was crawling toward the open sea sluice, his yellow-filmed eyes locked on the black water churning beneath the iron grating.

His crouch made his intent clear: meet them in the channel.

"Stay out of that culvert," Suometar snapped, lunging past the breaker panel to kick the hydraulic lever.

The heavy steel sluice gate crashed down into its tracks with a deafening, iron-shod bang, sealing the intake conduit from the open bay. Spray erupted through the drain slots, washing across her rubber work boots. Kaarle-alt struck the barred hatch shoulder-first. The impact rang like a struck buoy, but the manganese steel held.

He whipped around, baring two rows of translucent, needle-pointed teeth. A guttural hiss scraped from his throat, carrying an ultrasonic edge that set her molars throbbing. The pale gills along his collarbones pulsed in frantic, ragged flares. He crouched, webbed fingers splayed on the deck plates, ready to launch himself at her chest.

"You go out there, and they tear you into bait," Suometar said, stepping between him and the emergency release. Her voice was flat, hardened by years of shouting over diesel pumps. "And when three bull anomalies churn the sound into bloody foam, the cutter will not bother with hydrophones. They will drop five-hundred-pound depth charges until the entire shoal is gravel."

Kaarle-alt held her gaze. The black pools of his pupils contracted, leaving thin rings of predatory gold. His chest hum dropped an octave, vibrating through the flooded floorboards until the water in her bucket rippled in tight geometric rings, yet he did not advance. He remained poised on his knuckles, his flared nostrils drawing in the cold brine pouring down the walls.

Suometar turned her back on his claws and went to work.

If she could not silence the beacon, she had to drown it in a bigger lie. The auxiliary transformer on the wall was already warm from the short circuit fifteen minutes earlier, smelling of scorched rubber and ozone. The delicate passive hydrophone array could not survive another high-voltage jolt, but the station still held two low-frequency culvert transducers bolted into the concrete foundations. They were designed to pulse sonic vibrations into the pipes to prevent blue mussels from crusting inside the impellers.

She grabbed a pair of insulated wire strippers and ripped the rubber boots off the master calibration leads.

Her fingers worked by muscle memory, untangling the shielded coaxial cables and jamming the bare copper cores into the transducer amplifier inputs. She needed to invert the frequency envelope. Kaarle-alt’s territorial hum was an erratic, rising trill—a wounded challenge that invited every roving apex beast in the Baltic trench to claim his carcass. To drive them off, the station had to broadcast something terrifyingly wrong: an ancient, unyielding acoustic pulse that simulated an apex predator three times their size, rooted deep within the bedrock.

She reached for the analog sweep generator on the upper shelf, spinning the bakelite dial to forty-two hertz.

Beside her, Kaarle-alt crept closer to the workbench, drawn by the rising whine of the capacitors. His claws clicked against the steel risers. He reached out one long, webbed finger toward the brass calibration fork resting on her leather tool roll.

Before he could pinch the metal between his claws, Suometar struck the fork against the bench vise.

The brass prongs rang with a piercing, sustained tone. The sharp vibration sheared through the humid cellar air. Kaarle-alt flinched violently, his ears pinning flat against his skull as he swatted at the humming fork with a swift, defensive swipe. The tool bounced off the concrete slab with a hollow clatter.

"Leave the calibration tools alone," Suometar muttered without looking up. "It is not an oyster."

Kaarle-alt crouched over the fallen fork, sniffing the brass with deep suspicion before nudging it with the back of a knuckle.

Suometar pulled the patch cord tight, bridging the sweep generator directly into the fifty-amp auxiliary bus. The rheostat was stiff, seized by decades of salt corrosion, but she locked her wrist and forced the brass needle across the scale. The oscillograph screen flared bright green, tracing a fat, jagged sine wave that crested every twenty-four milliseconds.

If the ceramic fuses blow before the wave propagates, the trench beasts hit the turbines. The calculation was cold, mechanical, and entirely hers. If the coils melt, the whole array goes dark forever.

She flipped the polarity toggle, inverting the phase.

"Get down," she ordered.

She slammed the master knife switch home.

The station did not roar; it shuddered from the bedrock up. The culvert transducers dumped forty thousand watts of focused acoustic energy into the flooded foundation channels. The standing water on the workshop floor did not splash—it pulverized into a fine, freezing mist that hung in the air like fog. The low-frequency shockwave traveled through the intake conduits, blasting out into the sound at fifteen hundred meters per second.

Through the soles of her boots, Suometar felt the impossible pressure of the pulse. Her diaphragm spasmed, the breath driven out of her lungs as the walls groaned under the hydrodynamic recoil. Across the room, Kaarle-alt flattened himself against the damp concrete, his claws dug deep into the drain seams, his fins clamped tight against his neck as the artificial challenge rolled through his bones.

On the waterfall display, the two descending green plumes slammed into the invisible wall of sound.

For three seconds, the lines smeared into jagged bursts of static. The deep-water signatures halted in the cold trench ten miles out, their forward momentum broken by the overwhelming acoustic illusion of a monstrous, territorial leviathan vibrating beneath the shoals.

Then the vectors sheared apart.

The green blips wheeled violently to the west, banking away from pump station four and diving back into the deep abyssal trenches of the central gulf. The threat was scattering.

Suometar exhaled, reaching out to cut the throttle.

A violent blue arc snapped across the transformer housing. The ceramic fuses she had recently installed shattered into smoking white dust. A blinding flash tore through the back of the console as the transducer coils melted inside their oil baths, spewing acrid gray smoke into the cellar. The oscillograph tube cracked with the sharp pop of an incandescent bulb, and the waterfall screen died into absolute, impenetrable blackness.

The hum died instantly. The only sound left in the workshop was the steady, rhythmic drip of condensation falling into the sludge troughs.

Suometar stood in the gloom, her knuckles raw and trembling against the charred bench. The station was safe from the trench beasts. The foundation was intact. But the primary acoustic array—the eyes and ears that had kept her employed and isolated for seven years—was nothing more than melted copper slag.

Beside the dead console, Kaarle-alt slowly rose from the floor. He wiped a smear of brine from his chin, his yellow eyes tracking the drifting gray smoke before settling on her face. For the first time since she had dragged him from the turbine, there was no bared tooth, no defensive hiss. He simply watched her, looking as though he recognized the power that had just driven his rivals into the deep.

Then the emergency marine radio on the upper bulkhead screamed.

The high-gain speaker squawked through two layers of static, the volume pegged at emergency override.

"Station Four, acknowledge," Foreman Oksala’s voice barked, sharp and gravelly over the speaker cone. "Tuominen! We just lost your entire sector feed on the regional board. Your acoustic telemetry went zero-datum across all twelve channels."

Suometar did not touch the microphone. She stared up at the rattling metal speaker.

"Station Four, respond immediately," Oksala demanded, the sound of diesel engines roaring in the background of his transmission. "Patrol Cutter Kuha logged an unclassified high-energy seismic spike from your sector coordinates before your board dropped. Automated scouring protocol flags that as a catastrophic anomaly strike."

Static hissed, followed by the clatter of a heavy marine clipboard on the shore end.

"Cutter Kuha is altering course right now," Oksala snapped. "They are five miles out, steaming under full throttle. ETA twenty minutes to your dock for emergency inspection. Tuominen, get your station hatch unlocked."

The radio clicked into silence, leaving only the open-carrier hiss.

Suometar lowered her gaze from the ceiling to the flooded floor. Kaarle-alt stood tall in the murky water, pale, dripping, and undeniably monstrous, his black claws gleaming against the iron drain grates.

She grabbed the heavy crowbar leaning against the workbench and tossed a bundle of dirty hemp rags onto the maintenance hatch.

"Twenty minutes," Suometar said to him, her voice dead steady. "Move."
