    • Marine seismics with a pulsed combustion source and Pseudo Noise codes 

      Askeland, Bjørn; Hobæk, Halvor; Mjelde, Rolf (Peer reviewed; Journal article, 2007-03)
      There has been an ongoing debate for years of how dangerous seismic surveys are with respect to marine life. Marine seismics is today dominated by airgun technology, where high energy is generated by a release of compressed ...

    • A seismic field test with a Low level Acoustic Combustion Source and Pseudo Noise codes 

      Askeland, Bjørn; Ruud, Bent; Hobæk, Halvor; Mjelde, Rolf (Journal article, 2007-01-20)
      The Low level Acoustic Combustion Source (LACS) is a new type of pulsed underwater acoustic source with an output level of 0.5-1.0 barm peak to peak. The source is based on a combustion engine and intended for shallow ...
