Extended Data Figure 1: Tidal flows near the PIIS calving front.
From: Vigorous lateral export of the meltwater outflow from beneath an Antarctic ice shelf
Major axis of tidal ellipse for each individual tidal constituent from a mooring deployed in the area of the main meltwater outflow from the PIIS (Fig. 1), at nominal depths of 310 m (measured with an acoustic Doppler current profiler, black symbols) and 671 m (measured with a current meter, red symbols). Tidal ellipses are computed using harmonic analysis33. The amplitude of each ellipse’s major axis is shown by dots, and error estimates are displayed as bars. The 2-year-record-mean flow speed for each of the two instruments is indicated in the inset.
