Abstract

The cryosphere harbours diverse microbial communities which are contributing to the global carbon budget. Various ice ecosystems like ice covers of freshwater lakes, sea ice and supraglacial areas are highly sensitive to temperate rise due to resulting enhanced availability of liquid water which is the prerequisite for life. To assess the overall importance of these communities we require a non-invasive tool which provides high resolution measurements of photosynthetic pigments such as phycoerythrin. Here we present the preliminary calibration processes for L.I.F.E. (laser induced fluorescence emission).
