The ocean
is speaking.
Are we listening?

We build intelligent audio and visual monitoring tools for scientists, coastal communities, subsistence wild capture practitioners, and farmers working to understand what blue forests are saying — coral reefs, kelp, mangroves, and eelgrass — and act on it before it’s too late.

01 — The Problem

Blue forests are fading.
Silently.

Coral reefs, kelp forests, mangroves, and eelgrass meadows are Earth’s blue forests — together supporting the vast majority of marine biodiversity and sequestering carbon at a planetary scale. Yet they’re all disappearing faster than we can measure them. The challenge isn’t just restoration. It’s knowing whether restoration is working.

02 — The Discovery

Sound is a blue
forest’s fingerprint.

Every healthy blue forest hums with a distinct acoustic signature. Coral reefs crackle with snapping shrimp and calling reef fish. Kelp canopies shelter their own chorus of snapping shrimp and vocalizing rockfish. Mangrove channels and eelgrass meadows ring with pistol shrimp and the low-frequency calls of territorial fish. Across all of these ecosystems, larvae and juvenile fish navigate by this biological sound to find suitable habitat.

Playing healthy-habitat recordings near degraded sites dramatically increases settlement — a scalable, non-invasive restoration lever. But there’s a catch: we still can’t reliably verify whether a soundscape’s changes reflect real biological recovery. Do acoustic indices actually track biodiversity? The science remains unsettled. That’s exactly the problem we’re solving.

03 — The Innovation

Introducing
SEASCAPE.

Our flagship prototype
SEASCAPE
Stereo-Enhanced Acoustic and Camera Array for Passive Ecosystem Monitoring

Three stereo-vision pairs paired with directional hydrophones — delivering full 360° visual and acoustic coverage of the reef environment. What the cameras see, cross-validated in real time against what the hydrophones hear.

SEASCAPE is the first integrated blue-forest monitoring system that correlates stereo depth perception with passive acoustic data — letting us objectively answer whether a habitat’s soundscape reflects its true biological state, whether that habitat is a coral reef, a kelp forest, a mangrove channel, or an eelgrass meadow.

04 — The Technology

Built for
long endurance

Stereo depth perception — Three stereo-vision pairs reconstruct 3D fish trajectories, automatically distinguishing swimming larvae from drifting debris — a problem unsolvable with 2D cameras.

SLIP coatings — Organic, non-toxic slippery liquid-infused porous surface coatings prevent biofouling, keeping optics clear across months of deployment rather than weeks.

Lunar-scale deployments — Extended battery life lets us capture multiple lunar cycles — the natural rhythm of larval settlement — closing a fundamental gap in existing monitoring systems.

05 — The Mission

Science that scales
like software.

Our AI-powered pipeline turns months of raw video and acoustic data into actionable ecological intelligence — automatically, at scale, without requiring researchers in the water or disturbing natural marine behavior.

The goal: give blue-forest managers trustworthy, objective monitoring tools that tell them whether their restoration work is producing a healthier ocean. From coral reefs to kelp forests, mangrove channels to eelgrass meadows — every ecosystem that buzzes with snapping shrimp and singing fish deserves the same rigorous acoustic baseline.

We’re building the infrastructure for blue-forest restoration to finally scale.

The Study

A reef that’s lost its voice
can learn to sing again.

Acoustic enrichment (AE) — the playback of ambient sound from healthy coral reefs — shows promise in attracting fish larvae to degraded or artificial reefs. Previous evaluations relied on invasive diver-based sampling, limiting most studies to short deployments in calm, accessible environments.

This study used fully autonomous cameras to non-invasively evaluate AE efficacy across large fractions of a lunar cycle. Autonomous AE systems were deployed in Kāneʻohe Bay (Oʻahu, Hawaiʻi) over three spawning events — August 2023, June–July 2024 — at 5 m water depth on a sandy seabed.

“Treatment and control designations were alternated between deployments to remove potential spatial bias over multiple years, months and lunar cycles — ensuring the fish larvae response we detected was real.”

Key Findings

The numbers
don’t lie.

4–14×more larvae at acoustic enrichment sites vs. control
larval counts peaked around the new moon at both sites
3spawning events studied across two field seasons

Larvae follow the sound

Settlement-stage fish larvae used acoustic cues from the healthy-reef recordings to navigate toward the treatment site — even on a featureless sandy seabed.

🌕
Lunar synchrony

Both treatment and control sites peaked in larval abundance near the new moon, consistent with known lunar-cycle spawning behavior in tropical reef fish.

Non-invasive monitoring

Fully autonomous open-source cameras ($255 USD per unit) ran continuously for weeks without diver intervention — capturing behavior undisturbed by human presence.

Scalable protocol

The AE system is low-cost, battery-powered, and off-grid capable — designed to be deployable across diverse reef restoration sites globally.

The Soundscape

What does a
healthy reef sound like?

The acoustic enrichment recordings were collected from a vibrant reef 300 m from the experimental site in Kāneʻohe Bay during the new moon (August 27, 2022). Hawaiian snapping shrimp (Synalpheus parneomeris) and reef fish, including the Hawaiian Damselfish (Dascyllus albisella), dominate the ambient sound field.

These low-frequency biological sounds carry further underwater than high-frequency signals, making them effective long-range navigational cues for larvae orienting toward settlement habitat. The reef’s “fingerprint” is as unique as its ecology.

What’s Next

From field observation
to intelligent monitoring.

These results confirm that acoustic enrichment meaningfully shifts larval settlement behavior. The next frontier: proving that the acoustic signal itself reliably tracks the biological recovery we’re inducing.

That’s where SEASCAPE comes in — combining stereovision cameras with the same passive acoustic monitoring infrastructure to visually ground-truth what the hydrophones are hearing, deployment after deployment, lunar cycle after lunar cycle.

The question is no longer does it work? It’s how do we prove it, at scale, for every reef?
