The base platform

A dead zone is not a permanent condition.

Water goes anoxic because the oxygen leaves faster than it returns. SeaBreather returns it — at depth, at volume, from a vessel that goes to the water instead of waiting for the water to come to a plant.

The argument

Treatment plants wait. Water does not.

Almost every tool built for bad water assumes the water will be brought to it. Pipe it, pump it, hold it, treat it, send it back. That works for a municipal supply. It does not work for a bay.

A hypoxic estuary in August is a moving problem. The oxygen deficit sits in a layer, the layer shifts with tide and wind, and the fish that die do so in the three days before anyone has agreed on a budget line. By the time an intervention is designed around fixed infrastructure, the season is over and the loss is booked.

So we built the treatment around the vessel instead. SeaBreather carries its gas handling, its reactor and its instruments on a hull that can be in the affected water the same week. The plant does not wait for the water any more. It draws the affected layer in, works on it inside the hull, and puts it back where the deficit sits — and it moves as the problem moves.

That is the whole design premise. Everything else — the nanobubble physics, the telemetry, the fleet routing — exists to make that premise pay.

What the platform is for

Three jobs, done from the same hull.

Dissolved oxygen restoration

Hypoxic and anoxic water brought back above the survival threshold, and held there through the season rather than for an afternoon. This is the core service and the reason the platform exists.

Fishery oxygen boost

Targeted oxygenation around net pens, nursery grounds and landing areas, where a few hours below threshold is the difference between a harvest and a write-off.

Thermal hot-spot mitigation

Warm water holds less oxygen and stratifies harder. Breaking a thermal cap where it forms addresses the cause of the deficit, not only the symptom.

And a fourth, on the way to the others.

Deep Strike is proactive interception — treating the adjacent water where a bloom or a deficit is forming, before it arrives in the service zone as somebody's emergency.

Why it matters commercially

A base subscription that only reacts is priced against the events it cleans up. A subscription that intercepts is priced against the events that never happen — which is both cheaper to deliver and worth more to the buyer.

Deep Strike is included in the base service zone for exactly that reason.

How the treatment works

Nano Bubble Oxidation Technology, in one paragraph.

Gas is sheared into bubbles small enough that they stop behaving like bubbles. Below roughly a micron they no longer rise and burst; they carry a surface charge, stay suspended, and hand their gas to the water across an enormous combined surface area.

Published work on nanobubble aeration has measured the gas–liquid mass transfer coefficient rising roughly elevenfold against conventional bubbles for the same delivered gas volume. That is the physics the platform is built on: not more gas, but gas that actually dissolves instead of escaping to the sky.

The full technical account

A dense column of fine bubbles rising through dark water
Conventional aeration puts most of its gas back into the atmosphere within seconds. The size of the bubble decides whether the oxygen ends up in the water or in the air above it.

Operating answers

The four questions a first meeting opens with.

A harbormaster, a fisheries directorate and an environment ministry arrive with the same list. The answers are flat.

  • The water comes to us, and it does not stay. It is drawn in, worked inside the hull, and returned oxygen-enriched — at a specified rate near 5,000 gallons a minute, which is the plainest answer to anyone picturing your bay held in a tank pending approval. What goes back is held to the specification fixed for that outlet before a hull sails, set with the authority that issues your consent and read as it lands by a verifier who does not work for us. Contained means enclosed and instrumented. It does not mean impounded.
  • The water body stays in use. No enclosure, no drawdown, no dredging. Berths, pens and bathing water carry on working while the vessel does.
  • Oxidation is a separate duty, and its residuals are governed. SeaBreather is the hull and the oxygen work. A mission needing an oxidant runs as HABslayer or ChemSlayer. Bromate and the rest of the residual question answer to the limit that applies to your receiving water — fixed with the authority that consents the work, written into the agreement before deployment, and never lifted from a drinking-water rule that was drafted for a tap. Monitoring is live. An outside verifier reads it, and you can stop an active deployment on a suspected infraction. Where a bay needs more than oxidation it gets more: separation and treatment capability beyond that stage rides the same program, is picked against the event rather than the brochure, and answers to the same final state in front of the same verifier.
  • The catchment work still has to happen. Loading is generated on land, and cutting it upstream is the twenty-year answer — one that should be started rather than deferred. The vessel holds the condition of the receiving water across the years that takes.

The program

A service zone, not a project.

What Alarivean sells is better water — defined outcomes inside a defined service zone, bought as an ongoing subscription. The hull is not for sale and it is not for hire. Nobody buys system-time either. The base subscription covers proactive protection and adjacent Deep Strikes; upgrades add capability or widen the zone.

SeaBreather vessel tiers and the service zones they suit
Vessel tier Typical water Suits
Nimble Marinas, creeks, inner harbors, aquaculture blocks, shallow lagoons A single asset or a single stretch of shoreline with a recurring seasonal problem
Standard Bays, estuaries, port basins, desalination intake approaches, reef margins A municipal or industrial service zone with several assets and a defined season
Mega Large open zones, multi-site coastlines, national programs A regional or sovereign program routed as a fleet rather than a vessel

Base subscription

Continuous service against the outcomes written for that zone, with SeaBreather vessels in the water and all gases and natural augments included, proactive zone protection and adjacent Deep Strikes to intercept events before they grow.

On the record

Where the platform has actually been in the water.

One permit number, one regulator, one bounded trial with conditions printed on it.

In September 2024, Alarivean, Inc. received Florida Department of Environmental Protection permit FLOA00062 for a red tide mitigation field trial using an ozonated-seawater craft, under a five-year window, with the trial conditioned on active Karenia brevis above 100,000 cells per liter. The Sarasota Bay Estuary Program and the Florida nonprofit START both wrote it up on their own sites.

A permit is not a demonstration of scale, and the estuary program has said as much in public. It backed the application with technical work and, by choice, with none of its own money — which leaves it able to publish whatever the readings show. What it wants is the measuring role in open water before anything is claimed past that bay. Alarivean wants the same, and for the same reason.

Alarivean also completed the term of a Cooperative Research and Development Agreement with NOAA. Work under it with the agency scientist Dr Peter Moeller established that this treatment sterilizes toxins by disabling the functional groups that make them toxic, rather than precipitating them out. That term is finished and nothing has replaced it. Dr Moeller stays involved as an advisor on the research instead, and the work since has run with Arizona State University, the Middle East Desalination Research Center and KAUST, whose facilities fit the scale being tested next. CRADAs are private instruments and are never posted, so the document itself is not a public one; the finding is the company's own account of its own research. A research agreement is not an endorsement. No federal agency endorses a commercial product, and none has endorsed this one.
