Finland: AI Satellite Monitors Algae Blooms
AI-Powered Satellites to Tackle Harmful Algal Blooms & Beyond

Harmful algal blooms, often caused by cyanobacteria, pose a growing threat to both human and animal health. But identifying these blooms quickly and accurately is a challenge. Now, a partnership between Kuva space and Skye is leveraging the power of artificial intelligence and hyperspectral satellite imagery to revolutionize how we monitor – and ultimately mitigate - these environmental hazards.
Cyanobacteria, sometimes referred to as blue-green algae, can produce toxins harmful to humans and animals. Exposure can occur through drinking contaminated water, swimming in affected areas, or even consuming fish that have ingested the toxins. The blooms can disrupt ecosystems, impacting recreational activities and local economies.
However, visually distinguishing cyanobacteria from other, harmless algal blooms is nearly impractical.Current monitoring relies on collecting and analyzing water samples – a process that’s both time-consuming and expensive. This delay in detection can exacerbate the problem, allowing blooms to spread before effective action can be taken.
A New Approach: Hyperspectral Imaging & AI
Kuva Space and Skye are pioneering a more efficient and proactive solution. They are training advanced AI models using a rich dataset comprised of hyperspectral satellite imagery, alongside conventional water sample analysis and insights from biochemical and genetic research.
Hyperspectral imaging captures light across a much wider spectrum than traditional satellite imagery, revealing subtle differences in the chemical composition of water. This allows the AI to identify not just the presence of algae, but also the specific species and estimate its biomass.
“We’re very excited about this pilot with Kuva Space because rather than just detecting the presence of algae, we can use Kuva’s hyperspectral technology and AI to explore the spectral range and take a step further in identifying which algae species are present and assessing their biomass,” explains Jenni Attila, leading researcher & group manager at Skye.
Kuva Space: Building a Constellation for a Smarter Planet
Kuva Space launched its first hyperspectral satellite, Hyperfield-1A, in August 2024, marking a significant step forward in this technology. The company has enterprising plans to deploy a constellation of 100 satellites by 2030.
These orbiting probes won’t just be focused on algal blooms. Their ability to analyze the chemical compositions of both natural and manmade materials opens up a vast range of potential applications. Kuva’s technology is uniquely positioned to provide detailed, actionable data across multiple sectors.
Beyond Algae: Diverse Applications of Hyperspectral Technology
The versatility of hyperspectral imaging and AI-powered analysis extends far beyond environmental monitoring. Here are just a few potential use cases:
Agriculture: Optimize crop monitoring, identify nutrient deficiencies, and improve yields.
Defense: Enhance surveillance capabilities and improve situational awareness. Industrial Safety: Detect chemical leaks and monitor environmental compliance.
Marine Conservation: Track aquatic species, assess water quality, and combat illegal fishing.
This technology represents a paradigm shift in how we understand and interact with our planet, offering a powerful new tool for addressing some of the most pressing challenges facing humanity. By providing timely and accurate data, Kuva Space and Skye are paving the way for a more sustainable and secure future.
