Water Quality Management
Harmful Algal Bloom Detection & Monitoring from Space.
Blue-green algae outbreaks are increasing worldwide. Most organisations still rely on monthly sampling, finding out from complaints instead of data. There is a better way.
How it works
Every data source, one picture of your water body
Satellite coverage, weather feeds, and ground sensors get layered together. Each one fills gaps the others miss. The result: continuous bloom intelligence no single source could deliver alone.

Case study
Lough Neagh: 383 km² of lake, monitored from orbit
Lough Neagh, the UK's largest freshwater lake, supplies 40% of Northern Ireland's drinking water. It is classified as hypereutrophic (high level of nutrients) and suffers from toxic blue-green algae blooms. Amelia's Planetary Intelligence Platform provides satellite data on algal bloom patterns that are difficult to track fully from the shoreline.
Three years of continuous monitoring using optical and SAR imagery, seeing through cloud cover.
Each validated against ground truth. The platform identified events before ground teams documented them.
Bloom movement, seasonal trends, and hotspot zones revealed from historical data.
Full lake coverage in every observation, with site selection intelligence for equipment deployment.
Seen from space
The same lake across 2025. Clear water in March, toxic bloom by August.


Sentinel-2 optical imagery, 10m resolution. Contains modified Copernicus Sentinel data.

The pipeline
From satellite signal to decision
The Planetary Intelligence Platform processes data through four stages. Each stage adds intelligence. By the time it reaches you, it's not data anymore. It's a decision.
Detect
Satellite imagery monitors your entire water body every few days. When cloud cover blocks optical sensors, radar sees through. Ground data fills the gaps.
Understand
AI identifies bloom events, maps spatial extent, tracks movement, and correlates with environmental drivers like temperature, wind, and nutrients.
Predict
Risk models combine historical patterns with current conditions to forecast bloom probability before conditions escalate.
Act
Intelligence becomes decisions: where to sample, where to deploy, who to alert, when to activate remediation.

Detection to remediation
Through integrated partnerships, intelligence connects directly to action. When the platform identifies where intervention is needed, remediation teams know exactly where to deploy.
Right now, somewhere in the world, a bloom is forming. Your water body could be next.

Common questions
Optical satellites measure chlorophyll concentrations and water colour from orbit, while radar satellites detect surface roughness changes caused by bloom activity, even through cloud cover. Amelia's Planetary Intelligence Platform ingests imagery from multiple satellite programmes, including ESA Copernicus (Sentinel-1, Sentinel-2) and NASA missions (such as Landsat), then combines these signals with environmental data to identify, classify, and track bloom events across entire water bodies.
Frequency depends on latitude and the number of satellite passes that cover the water body. At mid-latitudes, radar imagery is typically acquired 4 to 5 times per week, and optical imagery every 2 to 3 days in cloud-free conditions. Combined, most freshwater lakes receive new satellite observations almost daily. When ground sensors or drone flights are connected, the picture updates even more frequently.
Satellite monitoring works for water bodies from approximately 0.5 km² upward. Larger water bodies benefit most because satellite coverage captures the full spatial extent in every observation, something that would require dozens of ground sampling points to achieve.
Optical satellites measure light reflected from the water surface, revealing chlorophyll concentrations and bloom extent, but they cannot see through clouds. Radar (SAR) satellites use signals that penetrate cloud cover, detecting surface roughness changes caused by bloom activity. Amelia's Planetary Intelligence Platform ingests both optical and radar imagery from ESA, NASA, and commercial providers, along with environmental data, to provide monitoring regardless of weather conditions.
Amelia's risk scoring models can identify conditions favourable for bloom development before a bloom becomes visible, by combining historical patterns with current environmental data such as temperature, wind, and rainfall. Once a bloom begins forming, the platform typically identifies it within one to two satellite passes, often days before it would reach levels that trigger complaints or affect water treatment.
Amelia's Planetary Intelligence Platform brings together satellite imagery, environmental data, and where available, ground observations into decision intelligence. It is designed to ingest data from multiple providers including ESA Copernicus and NASA programmes. For water quality, this means combining optical and radar satellite data with weather feeds and historical patterns to detect, track, and predict algal bloom events, providing continuous visibility instead of periodic sampling.
