− | Contourites are oceanic sedimentary deposits originated by the circulation of thermohaline oceanic currents of contour, named this way because they follow bathymetric curves. These currents are caused by the global marine circulation and correspond to those of low temperature, which together warm temperature currents, conform a system of vital importance. These currents may flow upwards, downwards, around or above obstacles or irregular topographies. | + | Contourites are oceanic sedimentary deposits originated by the circulation of thermohaline oceanic currents of [[contour]], named this way because they follow bathymetric curves.

| In addition of taking part in the regulation of global temperatures and the distribution of the marine fauna, countour currents generate across-slope processes, that together with along-slope processes, dominate large part of the sedimentary dynamics in deep marine environments, either within the continenetal slope or the continental rise. Along-slope processes may generate drift or contouritic features. The latter are less known than the former, which are considered erosional terraces, contourite channels, abraded surfaces, moats and furrows (Hernandez-Molina et al.,2008). | | In addition of taking part in the regulation of global temperatures and the distribution of the marine fauna, countour currents generate across-slope processes, that together with along-slope processes, dominate large part of the sedimentary dynamics in deep marine environments, either within the continenetal slope or the continental rise.
