What specific problem are you solving?
Our oceans are rapidly warming and acidifying, with the Gulf of Maine warming faster than 95% of the world’s oceans. This is leading to disastrous weather events as well as ecosystem and fishery collapse. Oceans offer climate solutions at globally relevant scales, but to leverage them effectively, we need to drastically improve our ability to collect data in the ocean.
Aquaculture now produces more seafood globally than wild fisheries. The US, despite its $20B trade deficit and rich ocean resources, is falling behind. Responsible growth of domestic aquaculture could create jobs, provide low-carbon food, and support coastal restoration - but it requires better ocean data to streamline permitting and ensure sustainability.
At the same time, the latest IPCC report highlights the urgent need for Carbon Dioxide Removal (CDR). The ocean, already our largest carbon sink, holds immense potential for scalable carbon removal. With over 50 research field trials underway, robust monitoring is critical to measure carbon removed and safeguard marine ecosystems.
From climate stability to food security, the ocean is central to our future. But we can’t manage what we don’t measure. Investing in ocean monitoring is essential for responsible innovation, resilient coastal economies, and a livable planet.
What is your solution?
Bluesonde is developing a fully integrated monitoring system that provides environmental data to customers. Our easy to deploy hardware empowers users to scale their ocean monitoring efforts instead of relying on sparse data or flying blind. By combining robust hardware with a web-based dashboard, we deliver real-time water quality data to support faster, more informed decision-making.
Designed for scalability and ease of use, Bluesonde’s solution can be deployed across a range of marine environments - from aquaculture farms and coastal monitoring stations to marine Carbon Dioxide Removal (mCDR) projects. Once installed, the system automatically transmits data to a secure online platform where users can visualize trends, set custom alerts, and adjust sampling schedules to align with operational goals or regulatory requirements. With continuous, high-resolution ocean data, customers can identify changes early, adapt quickly, and make smarter, science-informed decisions.
In an era where ocean health is critical to climate resilience and sustainable development, Bluesonde delivers the tools needed to understand and protect our marine environments - efficiently, affordably, and at scale.
Who does your solution serve, and in what ways will the solution impact their lives?
Existing tools for collecting data in the ocean are expensive and complex, leaving many ocean operators flying blind. Low cost alternatives include manual water sampling, which often misses key events, or referencing publicly available data which can be far away and significantly different from your operating conditions. High cost alternatives include ocean monitoring buoys that are significantly more expensive, require frequent maintenance and require large vessels to support deployment operations.
Our team at bluesonde experienced this while performing make vs buy analysis for ocean sensing hardware required to verify ocean CDR. To procure an autonomous buoy with various surface sensors results in purchasing components from several different vendors and piecing them together. This integration work requires technical expertise and also results in excess cost, size and unnecessary or duplicated components. Due to the time and cost required, this is often being done as “one-off” builds by ocean operators and researchers.
