a, Canyon bathymetry in the vicinity of the measurements used for this study was measured using a shipboard multi-beam during the BLT Recipes experiment. Thin contours are every 20 m and thick contours are every 100 m. The locations of the FCTD transects (black lines), 12-hour time-series station (orange circle), moorings (MP1, MP2, MAVS1, TCHAIN and MAVS2) and dye release are shown. M2 tidal ellipses for the MP1 and MP2 moorings estimated from the average velocity within 100 m of the seafloor are shown with a scale bar of 0.05 m s−1. The shading shows the logarithm of slope criticality to the M2 internal tide given the time-mean stratification from shipboard CTD stations during the 5-week-long experiment (not shown). b, Bathymetry of the full canyon based on global bathymetry products49,50. Thin contours are every 100 m and thick contours are every 500 m. The blue box marks the region shown in a. c, Bathymetry of the Rockall Trough based on global bathymetry products49,50, with contours every 1,000 m. The land is coloured in grey. The location of the canyon is marked by the blue cross.
