Ballast testing is the first step: the team place the SPIRULA vehicle in shallow water, adjusting its position and buoyancy by adding or removing weight. “It’s important that the vehicle lies horizontally in the water and that it’s slightly buoyant,” says project leader Ralf Bachmayer (front).

In May, the deep-sea monitoring system SPIRULA embarked on its inaugural expedition in ocean waters. The test off the Greek island of Milos in the Aegean Sea was an all-round success, to the great satisfaction of MARUM Professor Ralf Bachmayer and his research group.
