DIVING-PAM-II

Underwater Fluorometer with Miniature Spectrometer


The DIVING-PAM-II is the successor of the DIVING-PAM which 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 DIVING-PAM have been published.

The DIVING-PAM-II continues the manifold tested design of its predeccessor, but it possesses significantly advanced data aquisition and instrument control by employing state-of-the-art optical and electronic components.

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.
