The Institute for Geophysics (IfG) at Hamburg University and the Research Center for Marine Geoscience (GEOMAR) of Kiel University have developed new, wideband ocean bottom seismic stations (OBS) for long‐term, deep‐sea deployments of up to 1 year. A first long‐term pilot experiment of these stations was conducted in the Tyrrhenian Sea north of Sicily, in‐cooperation with the first long‐term, deep‐sea test of the European Ocean Bottom Observatory GEOSTAR [ Beranzoli et al ., 2000] by Istituto Nazionale di Geofisica e Vulcanologia (INGV). The seismic data retrieved prove that the new OBSs are useful for seismological studies. A large number of tele‐seismic earthquakes have been recorded in good quality; waves originating from such events pass the mantle and crust below the network, and thus provide important constraints on their structure.
