off the coast of Haffkrug in the Baltic Sea repeatedly performed strange bubble phenomena. These were observed in Haffkrug and Kellenhusen both at the end of September and March. The causes of these noises are still unclear, but experts such as Andreas Geist, graduate engineer in the municipal administration of Scharbeutz, and Wolfgang Jensen, former department head for flood and coastal protection, have hired various theories.

Spirit describes bubbling as an occasional phenomenon that occurs in many areas of the Baltic Sea. He attributes the noises to the fact that water from underground layers escapes on the water surface. In particular, the area in Kellenhusen, which is higher than the hinterland, could increase the blubberger alarms.

These methane sources occur at different water depths and could be generated in flatter areas by microbes that may be a heir from the ice age.
