Field sampling

Field sampling during an oceanographic cruise in the North Sea on board RV Simon Stevin. This is the first location where we found the electrogenic bacteria in the seafloor.

Field sites

In our field work, we have been able to demonstrate that long-range electron transport occurs in a wide range of habitats across the globe.
