      In this paper we talk about an acquisition system for seismic data. The Ocean Bottom Seismometer (OBS) is equipment designed to obtain the seismic marine data from the seabed. The main part of this paper is based in an ...
    • Time base stability of ocean bottom seismometers (OBS) 

      Shariat Panahi, Shahram; Manuel Lázaro, Antonio; Corrêa Alegría, Francisco (2009-11-01)
      Article
      Open Access
      During the past decades, Ocean Bottom Seismometers (OBS) have played a key role in permanent seismic activity monitoring at sea as well as allowing a better understating of the earth interior. Data collected by the ...

    • Time synchronization of a commercial seismometer through IEEE-1588 

      Pallares, Oriol; Shariat Panahi, Shahram; Río Fernandez, Joaquín del; Manuel Lázaro, Antonio (2011)
      Conference report
      Open Access
      Seismometers use a GPS signal for time synchronization and the seismic data are collected, time marked and stored. The precision of the time marks is a key parameter for the location and magnitude of an earthquake.Land ...
