Dynamics of the Ocean Floor



Different instruments are deployed in order to collect data on seafloor seismic activity. Some of these instruments, such as the ocean bottom seismometer and the ocean bottom hydrophone, were developed at GEOMAR. New pressure sensors which are anchored on the seafloor can be used not only to detect earthquakes, but can be incorporated into early warning systems for tsunamis. In addition to these research projects, the Geodynamics unit is involved in large-scale mapping of the seafloor using side-scan sonar. Specialized software is applied to process the data and produce bathymetric maps. These three-dimensional depictions of the seafloor deliver images of areas on our planet that are normally hidden from our eyes.

 The following instruments and components are deployed for investigation:
