Summary
In the changing world the need for comprehensive but cost-effective and digital information is urgent. Microalgae are principal targets for ocean and lake monitoring since their composition reflect the prevailing environmental conditions. Further, microalgae have properties that can be detected by imagers. However, the information that microalgae could provide is underexploited due to limitations of temporal, spatial and volumetric resolutions of the available protocols. I aim to harness the optical properties of microalgae to form a scalable and robust monitoring protocol. The core of the proposed method is to identify and quantify microalgae by hyperspectral imaging of samples. I will use microscopy, chromatography and cytometry to calibrate and verify the hyperspectral analysis. I will also test if optical properties are linked to the microalgae life stage by carrying out field studies of the under-ice environment - one of the least known environments in the boreal and arctic.
