DIVING-PAM

Underwater Chlorophyll Fluorometer

The DIVING-PAM Underwater Fluorometer is a worldwide unique instrument for studying in situ photosynthesis of underwater plants, including sea grasses, macroalgae, and zooxanthellae in corals.

Based on the large experience with chlorophyll fluorescence analyses of terrestrial plants, investigations using the DIVING-PAM have shaped a clearer understanding of underwater photosynthesis under natural conditions.

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