Dissolved oxygen restoration
Hypoxic and anoxic water brought back above the survival threshold and held there month after month, against loading that keeps arriving. This is the core service.
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.

Coastal dead zones counted worldwide, roughly doubling each decade since the 1960s

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 deficit sits in a layer, the layer shifts with tide and wind, and the fish die in the three days before anyone has agreed on a budget line. By the time fixed infrastructure is designed, the season is over and the loss is booked.
So the treatment was built around the vessel. SeaBreather carries its gas handling, reactor and instruments on a hull that can be in the affected water the same week, drawing the affected layer in and putting it straight back as it moves with the problem.
There is nowhere aboard to put your water. The hull travels. The water stays, oxygen-enriched, carrying a nanobubble cloud that goes on releasing oxygen into the column for hours to days after the hull has moved off.
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 load
Heat drives the oxygen out and stiffens the layering that would put it back. Breaking a thermal cap where one has formed works on the cause, and the oxygen follows. Where heat comes in from a wider sea, a nanobubble cloud held over a defined patch works the albedo effect against the solar load, carrying oxygen and shade together. That is part of what a site needs against heat, never all of it, and never a basin. Nobody has recorded a figure for the shade it buys. The first will come off your own water, against a baseline taken before the first pass.
And a fourth, on the way to the others.
Deep Strike is proactive interception — going to water where a bloom or a deficit is forming, in the next basin along or well out from the coast, and working it before it becomes somebody's emergency.
Where a coast drinks what its plants make, the column in front of an intake is somebody's tap, and a bloom can shut that intake without ever reaching a beach. Blooms can cause significant operational issues at desalination facilities, raising chemical consumption, fouling membranes faster, and in extreme cases taking a plant off-line (NCCOS data report, April 2018). That report reviews what is possible. It logs no outage and names no plant.
Why it matters commercially
A subscription that only reacts is priced against the events it cleans up. One that intercepts is priced against the events that never happen — cheaper to deliver, and worth more to whoever pays for it.
Left until it is an emergency, the same water needs a force mobilized at short notice, and that force charges for the waiting as well as the work.
Deep Strike is included in the base service zone.
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 reports oxygen transfer efficiency 1.5 times that of coarse bubbles, in a laboratory study. The platform is built on gas that dissolves instead of escaping to the sky.
Operating answers
Where the water goes, and what stays open.
For harbormasters, fisheries directorates and environment ministries.
- The water comes to the hull, and it goes straight back. It is drawn in, worked in passing and returned oxygen-enriched to the same place, at a specified rate near 5,000 gallons a minute. There is no storage aboard, and nothing is taken away to be dealt with elsewhere. What goes back is held to a specification set with your consenting authority before a hull sails and read as it lands by an independent verifier. 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 other residuals answer to the limit for your receiving water, fixed with the consenting authority and written into the agreement before deployment, never borrowed from a drinking-water rule. Where no regulation sets a figure, the known safety limits for marine life apply. Monitoring is live, an outside verifier reads it, and you can stop an active deployment on a suspected infraction. A bay that needs more than oxidation gets separation and treatment capability on the same program, answering to the same verifier.
- The catchment work still has to happen. Loading is generated on land, and cutting it upstream is the twenty-year answer. Start it now. The vessel holds the receiving water to the numbers in your agreement through the years that legislating, funding and building the upstream fix will take.
The program
A service zone, held year round.
SeaBreather goes out as a service. What a client signs is defined outcomes inside a defined service zone, held year round by the operating company licensed for that water. The hull is not for sale or hire, and system-time is not something a client buys. The base subscription covers proactive protection and Deep Strikes on forming water outside the zone; upgrades add capability or widen the zone, and the fleet is written to match.
| Vessel tier | Typical water | Suits |
|---|---|---|
| Nimble | Marinas, creeks, inner harbors, aquaculture blocks, shallow lagoons | A single asset or stretch of shoreline with a recurring seasonal problem |
| Standard | Bays, estuaries, port basins, desalination intake approaches, reef margins | A municipal or industrial service zone, several assets drawing on one basin |
| Mega | Large open zones, multi-site coastlines, national programs | A regional or sovereign program, routed as a fleet and sized to the water it has to hold |
Base subscription
Continuous service against the outcomes written for that zone: SeaBreather vessels in the water, all gases and natural augments, proactive zone protection, and Deep Strikes on forming water outside it wherever the program's fleet can reach.
It ends on two grounds only: performance outside the specification agreed for that water, or a client who has served the minimum subscription period and wants to stop. The second needs no reason.

On the record
Where the platform has 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, 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.
A permit is not a demonstration of scale, and the estuary program has said so publicly. It backed the application with technical work and, by choice, none of its own money. It wants the measuring role in open water before anything is claimed past that bay. So does Alarivean.
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 the treatment sterilizes toxins by disabling the functional groups that make them toxic, with nothing precipitated out. That term is finished and nothing has replaced it. Dr Moeller advises on the research, and later work has run with Arizona State University, the Middle East Desalination Research Center and more. CRADAs are private and never posted, so the finding is the company's own account. 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.
