At the bottom of the Ocean, in ~4000m water depth they can be found in high abundances: Manganese nodules. Industry and states are interested in these potato-sized objects as a new metal resource. But before commercial mining will start, the potential ecological impacts need to be investigated. Therefore, the project MiningImpact (funded through JPI Oceans) […]

Between a rock and a hard place…

Just as most scientists, geologists spend most of their working time in front of a computer (i.e., the hard place) – sometimes interrupted by some time in the lab, depending on your specialty.
