| Popis: |
A simple technique based on photoacoustic measurements allowed us to determine the biomass, as well as the efficiency of photosynthesis, for different taxa of phytoplankton in situ. The method yields rapid, direct results compared to tedious standard measurements of 14C fixation and oxygen evolution or compared to indirect results from measurement of fluorescence. The procedure has a high potential for following the effects of environmental parameters such as irradiance, nutrient status, and pollution on phytoplankton communities and their photosynthetic activity. |
