Sea floor topography and flow on the flanks of the MAR.

<p>(a) 3D projection from swath bathymetry surveys around the NW MAR station, vertical and horizontal scales the same. (b) Location of the NW mooring (base 2500 m depth) and flow at different heights above the sea floor. Red vectors - long term mean velocity. Green - ellipses of the dominant (M2) tidal constituent. (c) Diagrammatic cross section of a flank of the ridge showing the relationship between flat plains, gentle slopes and steep cliffs. The steep cliffs face towards the ridge axis.</p>
