High-resolution long-slit spectra along directions related to the major axis and to the radio-emitting region for the nearby Seyfert galaxy NGC 2992 are analysed. The rather complex velocity field obtained from the [O III] line profiles shows indications of radial outflows (PA 310°, PA 340°) and of tidal effects (PA 130°, PA 160°). The typical blue-asymmetry known from previous observations of the unresolved narrow-line regions is observed to exist only in the central 3arcsec. It is found that nuclear emitting regions can be distinguished from an off-nuclear region which appears dynamically decoupled from the former. The observed light distribution of both continuum and emission lines are discussed in terms of asymmetric obscuration effects due to the dust lane existing in NGC 2992.
