The single intelligent system
for ocean protection.

A new approach to ocean protection. Subsee brings together fragmented data, monitoring, and decision-making into a continuous system for prioritisation and action.
Designed for the institutions that govern, fund, and manage the ocean.
3.5%
Share of global ocean fully or highly protected, against a global target of 30% by 2030 (The MPA Guide, June 2026)
18,000+
Marine Protected Areas (MPAs) designated globally, the majority with no enforcement capacity
2026
The first legal pathway for high seas protection enters into force
WHY NOW

The legal foundations for transformative ocean governance are now in place. The operational infrastructure is not.

Three things are true simultaneously, for the first time.
01
/ TREATY
The Biodiversity Beyond National Jurisdiction (BBNJ) Agreement, the first legally binding treaty for the protection of the high seas, is now in force.
02
/ POLICY
The European Ocean Pact commits the EU to meaningful marine protection at scale.
03
/ TARGET
The 30×30 target requires 30% of the global ocean to be effectively protected by 2030. Globally we are way off track.

The bottleneck is not political will or legal authority. It is operational intelligence.
MPAs are designated but not enforced. Data is collected but remains siloed. Decisions are slow, reactive, and disconnected from ecological reality. Governance is fragmented across overlapping jurisdictions, institutions, and legal frameworks, with no mechanism to translate observation into coordinated action. Subsee was built to close that gap.

PLATFORM

From observation to action:
The missing layer in ocean governance.

The ocean is already being observed. Satellites, acoustic sensors, autonomous survey vehicles, and field teams generate enormous volumes of marine data every day. The problem is what happens next. Data reaches different institutions in different formats, to inform decisions that are rarely coordinated. Subsee sits above the observation layer, aggregates that data, applies its scoring methodology, and delivers the intelligence institutions need to act.

Ocean Protection Score (OPS)

A standardised, evidence-based framework for scoring the protection effectiveness of any ocean zone, including Marine Protected Areas (MPAs), Exclusive Economic Zones (EEZs), or high seas areas, into a single, comparable, audit-ready metric.
e.g. Zone score: 72 / 100

Data fusion

Integrates satellite imagery, acoustic survey data, bathymetric mapping, field observations, and regulatory records into one unified operational picture.

Protection intelligence

Identifies gaps in coverage, scores MPA effectiveness against management objectives, flags emerging threats in real time, and prioritises interventions by impact.

Decision support

Works within existing institutional structures, not replacing them, giving MPA managers, regulators, and enforcement bodies intelligence they can act on, audit, and report.

The oceans, rendered visible.

Data fusion

The world model needs a human interface. Subsee’s visualisation layer is a navigable, immersive 3D/4D* representation of any ocean zone. Fly through the seabed, surface live data layers, compare change over time. It is the window into the world model: making the ocean legible to anyone, with no specialist tools required.
*4D includes time

Knowledge & intelligence layer

The world model itself: a structured, continuously deepening understanding of how ocean systems work across physical, biological, human and governance dimensions. Every new data source expands the model’s causal understanding. Query it in plain language: “What are the top three threats to this zone this month?” to receive a prioritised, evidence-backed answer.

Central Arctic Ocean

OUR FIRST PILOT

Arctic: our first pilot

With the support of the Gordon and Betty Moore Foundation, Subsee is piloting our technology in the Arctic, bringing the platform’s intelligence layer to one of the world’s most ecologically critical and rapidly changing marine environments.

The Arctic represents a defining test for ocean protection intelligence: accelerating ecological change, extreme conditions, complex overlapping jurisdictions, and governance frameworks still evolving to meet the pace of the crisis. Subsee will apply its scoring methodology and data fusion capabilities to generate protection-grade operational intelligence for the region.

PARTNERS

Built with the institutions that lead ocean science, governance, and protection.

Subsee works with leading institutions in hydrographic data, ocean science, philanthropy, and marine conservation.
Focus Areas

High Seas MPAs: BBNJ Treaty

The treaty mandates protection of marine biodiversity in Areas Beyond National Jurisdiction (ABNJ) but has no operational infrastructure. Subsee fills this gap: Environmental Impact Assessment (EIA) support, 24/7 monitoring, Ocean Protection Score (OPS) scoring and adaptive management.

GET INVOLVED

Build the intelligence infrastructure for the next generation of ocean governance.

We’re actively seeking partnerships with institutions, funders, and researchers aligned with the 30×30 agenda and the post-BBNJ opportunity.

Funders & investors

Public and private, aligned with ocean protection, climate, and biodiversity outcomes.

Ocean governance institutions

MPA authorities, national hydrographic offices, regional sea conventions, BBNJ bodies.

Research & scientific partners

With marine data, field access, or modelling capabilities.

Why Subsee is the answer to this moment

The BBNJ window

The Treaty is in force but has no operational infrastructure. The organisations who build the first credible monitoring and accountability systems will define how it works for decades. That window is open now.

AI capabilities are exponential

Incumbent consortia treat AI as an add-on. Subsee treats it as a foundation. The gap between what a lean, AI-first team can deliver today versus five years ago is enormous and growing. Every month of delay is months of compound disadvantage.

The Arctic proof point

We have deployed. We have a replicable model. The hardest part, proving it works, is done. Partner with us to expand the model to additional regions.

Climate baselines are disappearing

These seas have already changed, and they are still changing. Without trusted, persistent baselines, it becomes harder to measure damage, track further decline, and prove where restoration is working. Every year without consistent data reduces our ability to understand what has been lost and what can still be recovered.

Methodology

A standardised, auditable measure of protection effectiveness — applied consistently across any ocean zone, and used directly by funders and governance bodies to demonstrate impact.

Architecture

Subsee sits above the sensor layer, not within it. We’re interoperable with every major observation system and don’t compete with existing infrastructure — we make it more valuable.

Timing

BBNJ, the European Ocean Pact, and 30×30 together create the first sustained institutional demand for ocean protection intelligence at scale. That’s the gap Subsee builds.
FAQ

Common questions

Answers to the most common questions about Subsee, our platform, and how we work.
Subsee is an intelligence layer for ocean governance. It integrates marine data from existing sensing systems, scores the protection effectiveness of any ocean zone, and delivers decision-ready intelligence to the institutions, funders, and scientists driving the 30×30 target.

The Ocean Protection Score is a standardised, evidence-based framework that translates complex multi-source marine data into a single, comparable, audit-ready metric of protection effectiveness for any MPA, EEZ, or high seas area.

Subsee is designed for the institutions that govern, fund, and manage the ocean, including MPA authorities, national hydrographic offices, regional sea conventions, BBNJ bodies, funders, and research partners.
No. Subsee sits above the sensor layer rather than within it. It’s interoperable with major observation systems and doesn’t compete with existing infrastructure. It makes that infrastructure more valuable.

Subsee’s first pilot is in the Arctic, supported by the Gordon and Betty Moore Foundation, applying its scoring methodology and data fusion capabilities to one of the world’s most ecologically critical marine environments.

The Biodiversity Beyond National Jurisdiction (BBNJ) Agreement is the first legally binding international treaty for the protection of the high seas, entering into force in 2026. It creates the legal pathway for area-based protection of the open ocean, but has no operational infrastructure. That is precisely the gap Subsee is built to fill.
