For over six years, our team has been exploring the underwater world of Greifensee—at a steady depth of 3 meters. Every hour, for 10 minutes, we’ve captured high-resolution images of aquatic life ranging in size from just 10 micrometres to 1 centimetre. The result? A staggering archive of over 60 million images (and counting)!
Each image is processed using a convolutional neural network (CNN) classifier that automatically identifies and categorises different types of plankton. This cutting-edge technology has allowed us to build one of the most comprehensive datasets of freshwater plankton ever.
Until now, visitors to our website have been able to view the latest real-time images of plankton drifting through the lake. But we’re excited to announce a major leap forward:
The launch of our real-time plankton composition dashboard! 🚀
Ever wondered how many Daphnias or Ceratiums were swimming in Greifensee just yesterday? Or even an hour ago? Now you can find out—instantly.
This new feature opens up exciting possibilities for researchers, educators, and nature enthusiasts alike. Whether you’re studying ecological trends or simply curious about the invisible life beneath the surface, our data is now just a click away.
We invite you to dive in and explore the dynamics of Greifensee’s microscopic world—hour by hour, day by day, year by year.
Stay tuned as we continue to unlock the secrets of Greifensee—one image at a time.
🙏 A big thank you goes to Stuart Dennis and James Runnalls for making this possible. 🙏
