Underwater Fluorometer with Miniature Spectrometer

The predecessor of the DIVING-PAM-II (the DIVING-PAM) has been proven as reliable and robust chlorophyll fluorometer for studying photosynthesis in and under water. To date, about 500 scientific papers containing measurements with the DIVING-PAM have been published.

The DIVING-PAM-II continues the proven and trusted design of its predecessor but advances data acquisition and instrument control by employing the latest progress in LED technology, optics and electronics.

In situ investigations of cyanobacterial photosynthesis using a Walz DIVING-PAM fluorometer has been released. The video was recorded during a research campaign in Greenland (2013) which was targeted to photosynthesis of algae on surfaces of submarine mineral formations (ikaide columns). This research campaign was sponsored in part by Walz.
