## World’s First “On-Demand” Autonomous Marine Water Sampling

### Tracking and Sampling Algal Blooms

The Centre for Environment, Fisheries and Aquaculture Science (Cefas) needed a way to track and sample algal blooms in the right place at the right time, to help scientists assess the health of our oceans. To solve this, together we created a mobile, responsive solution for on-demand autonomous water sampling. In this case study, you’ll learn how Cefas used the Wave Glider to:

- Navigate to areas of particular interest based on satellite data
- Collect samples on-demand via remote triggering of the Cefas Water Sampler
- Confirm the presence of the toxic *Karenia* sp. dinoflagellate
