Cooling coral reefs, securing coastal futures
Coral Reef Cooling Technology: oPodᵀᴹs provide targeted reef protection by circulating cooler deep water to prevent coral bleaching during marine heatwaves. oPodᵀᴹs naturally replicate ocean upwelling processes, supporting reef resilience across threatened coral like the Great Barrier Reef.

Blue Carbon's oPodᵀᴹs: gentle coral protection without infrastructure
As coral bleaching intensifies, reef-reliant economies face growing risk. Blue Carbon’s oPod™ offers a low-impact, energy-independent solution — cooling reefs with deeper ocean water to help them survive and regenerate naturally.
Trials indicate localised cooling of up to 8 °C within two hours under moderate swell, helping corals survive peak thermal stress events. Trials also indicate significant flow with low to calm conditions.

Non-invasive,
reef-safe design
oPodᵀᴹs require no permanent infrastructure — they’re secured with removable moorings and need no seabed construction. Deployed near, not on, coral structures, they protect sensitive ecosystems and can be repositioned in response to bleaching events.
Powered by nature, engineered for longevity
oPodᵀᴹs run entirely on waves and solar — with no external power, fuel, or emissions. With minimal maintenance, each unit is built for 7 to 10 years of ocean life. They operate autonomously and can be fitted with smart sensors for real-time environmental insight.
How oPod helps your aquaculture operations
oPod Aqua™
steady deep flow
oPod Aqua™ delivers a steady flow of deep, cool water into the upper layers of the pen.
• Constant cool water means reduced heat stress and reduced mortality.
• Deep water holds more dissolved oxygen, supporting fish health.
• Consistent fresh water reduces pests and disease.
• Constant flow means natural swimming — improved muscle, and reduced aggression.
oPod Mini™
live ocean data
oPod Mini™ is a compact, cost-effective data buoy designed to help farms meet monitoring requirements.
• Smart compliance coverage. Covers core parameters under EPA guidelines.
• Real-time data means reduced risk and reduced manual spot sampling.
• Rugged unit integrates easily without extra cost or complexity.
oPod Air™
reliable oxygenation
oPod Air™ is designed to deliver compressed air reliably, in swells as low as 0.2m upwards. Pair with oPod Aqua™ for improved circulation and oxygenation.
Ocean Intelligence - OI™
oPod Mini™ lets you forecast heatwaves, HABs and oxygen risks with clarity.
• Prediction that buys time.
• Scalable swarms for site-wide coverage.
• Detailed data plus predictive AI means faster, better decisions.
• See your ocean, clearly, right now.
Why operators are exploring oPods
Data-ready design means real-time monitoring of dissolved oxygen and temperature.
Ocean-powered air-pumping for diesel-free oxygen injection.
Lowers OPEX instantly.
No fuel or grid power required. Runs 24/7 using only wave and solar energy.
Owned, real-time data. Fewer surprises in a warming ocean.
Delivers pressurised flow to targeted locations across the site.
Government-backed. Industry-supported. Currently being piloted in Australian waters.
Scalable reef intelligence
Beyond local cooling, oPodᵀᴹs act as a platform for live reef data. Deployed in networks, they provide clear insight into temperature, salinity, pH, dissolved oxygen and chlorophyll — enabling fast, informed decisions across coastal regions.
oPodᵀᴹ Coral Cooling FAQs
oPodᵀᴹ trials have already demonstrated rapid local sea surface temperature reduction (-8 degrees centigrade).
Any reef system experiencing temperature stress from climate change, particularly in shallow tropical waters.
oPodᵀᴹs enhance natural ocean processes and support marine biodiversity without introducing foreign substances. oPodᵀᴹs replicate the upwelling typically found along the Great Barrier Reef.
