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.
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.
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.
Operating answers
The four questions a first meeting opens with.
A harbourmaster, a fisheries directorate and an environment ministry arrive with the same list. The answers are flat.
- The water comes to us. It is drawn in, treated inside the hull, and returned oxygen-enriched. Nothing is dosed into your bay, nothing is dispersed onto it, and nothing has to be chased down and taken back out afterwards.
- 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 with a discharge standard on it. SeaBreather is the hull and the oxygen work. A mission that needs an oxidant runs as HABslayer or ChemSlayer, and the water those duties release carries bromate at or below 10 micrograms per litre at the outlet, against Alarivean's own discharge standard. Prevented at source, not spotted afterwards.
- Nutrient loading stays on land. It is generated in a catchment and it will be cut in a catchment. The vessel holds the condition of the receiving water across the years that takes.
The programme
A service zone, not a project.
Aquatic Prosperity is sold as capacity held inside a defined area of water for a defined part of the year, with the base subscription covering proactive protection and adjacent Deep Strikes. Upgrades add capability or widen the zone.
| Vessel tier | Typical water | Suits |
|---|---|---|
| Nimble | Marinas, creeks, inner harbours, 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 programmes | A regional or sovereign programme routed as a fleet rather than a vessel |
Base subscription
Full-capacity service with SeaBreather vessels in water for the contracted season, 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 litre. The Sarasota Bay Estuary Programme and the Florida nonprofit START both wrote it up on their own sites.
A permit is not a demonstration of scale, and the estuary programme 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 holds a Cooperative Research and Development Agreement with NOAA. Work under it with the agency scientist Dr Peter Moeller established that this treatment sterilises toxins by disabling the functional groups that make them toxic, rather than precipitating them out. 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.
Where it goes to work
Bays, ports, fisheries, intakes.
Estuaries and bays
Stratified summer water where the deficit sits below the thermocline and the kill happens in days.
Fisheries and aquaculture
Net pens and nursery grounds where oxygen is the binding constraint on both yield and survival.
Desalination intakes
Intake approaches where organic loading and bloom material decide whether a plant runs or throttles.
Elsewhere in the system family
