1. A method of interrogating aerosols formed above a sea or earth surface to detect hydrocarbon gas seeps below the surface, comprising the steps of:

  • generating a beam of primary light radiation and directing the beam towards the surface, the beam being sufficiently intense and of such a spectral composition that the beam causes the aerosols to emit secondary light radiation;

    detecting the secondary light radiation emanating from the aerosols; and

    ,analysing the spectral content of the detected secondary radiation to determine whether the composition of aerosols indicates the existence of a hydrocarbon gas seep.
