Abstract
Disclosed is a pressure tolerant seismic source for deep water survey. The seismic source can include an electromagnetic coil for generating an electromagnetic pulse, a piston plate movable by said electromagnetic pulse, and a housing with a first chamber and a second chamber separated by each other via a common bulkhead arrangement. The seismic source can also include that the coil is arranged within the first chamber and the piston plate arranged within the second chamber. The seismic source can also include the second chamber is at least partly filled with a liquid coupled to the plate so that due to movement of the plate at least one pressure pulse is generated traveling through the liquid within said second chamber.
