Saturna Imaging System

Saturna Imaging System

To understand how microplastics break down, move through the oceans and collect on coastlines, researchers and community monitoring groups must quantify a robust set of particle size parameters. Saturna is a portable, standardized image collection system used to rapidly quantify and analyze microplastic physical attributes. 

Saturna is a standardized imaging and illumination device that plugs in to your computer and syncs to a standalone analysis web application to rapidly characterize and quantify visible microplastic particles. Use it to collect a robust set of size, colour and categorical metrics for visible microplastic samples (>400μm) like those collected from Manta trawls, neuston nets, beach quadrat samples and community studies.

      • Highly standardized built-in LED lighting system provides consistent and reproducible lighting for your microplastic samples
      • Compatible with any Windows PC and operated using our Mariana data portal or standalone analysis application
      • Provides physical size and colour data for all microplastics imaged
      • Computer pattern recognition and sizing algorithms calculate 11 discrete size calculations for every particle
      • Predictive colour models calculate repeatable and standardized average colour calculations for each particle
      • Compare your samples over spatial areas using our Mariana data portal for further insight and sample analysis
      • Use to collect high quality physical data for visible particles larger than 400μm in size
      • Integrated 8MP Sony IMX179 CMOS Imaging sensor provides high resolution data
      • Integrated ~4000k neutral white LED array and light-blocking shroud provide highly standardized microplastics images with consistent lighting for comparative size and colour analysis across time, location and external lighting conditions
      • Included QR Code background sheet provides accurate particle sizing reference for physical analysis computer vision algorithms
      • Use Saturna through our Mariana data portal or standalone application with any Windows PC
      • Waterproof hard case included for easy transport into the field (26cm x 20cm x 12cm)
      • Particles greater than 400μm are isolated from the environment using common collection protocols (e.g. net tows, community-based beach quadrat surveys)
      • The collected particles are placed on an included background sheet alongside one of our standardized calibration reference discs
      • The Saturna imager is placed over top of the particles and the included light-blocking shroud is placed over Saturna to block out external light
      • A new sample is registered and added on the Mariana data portal and a standardized image is captured of all particles on the background sheet
      • After you upload your image to Mariana, our team at Ocean Diagnostics analyzes your sample image with a proprietary image analysis software which was developed in-house specifically for microplastics' size analysis, color mapping and categorical particle predictions
      • Level of classification: an ODI technician analyzes visible microplastic particles (>400µm) for physical characteristics, including 11 size dimensions, 11 color metrics and a particle category prediction. The data output for each particle includes:

      1. Maximum Width (mm) 
      2. 2D Surface Area (mm2)  
      3. Convex Surface Area (mm2)  
      4. Perimeter (mm)  
      5. Convex Perimeter (mm)  
      6. Circular Equivalent Diameter (CED)
      7. Bounding Box Width (mm)  
      8. Bounding Box Height (mm)  
      9. Aspect Ratio  
      10. Circularity  
      11. Solidity  
      12. Average HSV Colour Value  
      13. Average BGR Colour Value  

      • Sample data including indexed particle images and CSV data sheets containing all of the above data metrics can be downloaded locally from Mariana
      • Use Mariana’s data analysis tools to create histograms, scatter plots, bar charts, and compare your samples to others on the platform
      • Desktop or laptop with USB type A port
      • Windows 10 operating system
      • Broadband internet connection
