Comparison between model and observations. (a) The power spectra of ocean speed at 534 m depth from the BSR5 mooring data (black) and of simulated ocean speed for the CTRL (blue), and TIDE (red) cases. The diurnal and semi-diurnal tidal peaks are marked by red arrows. (b) Observed and (c) simulated vertical sections of potential temperature in the Pine Island ice shelf (PIIS) cavity. Isopyncal contours of 27.70 and 27.75 kg m−3 are shown with black lines. Underwater vehicle measurements are conducted in January 2009 along the orange line in Fig. 1a. The ridge separating the inner and outer parts of the PIIS cavity is marked by green arrows.
