Fig. 1: Observations of dense overflows around Antarctica.
From: Circum-Antarctic bottom water formation mediated by tides and topographic waves
a Observed overflow sites around the Antarctic coast14. The insets indicate the Weddell Sea and Ross Sea overflow sites, respectively. Black dots in the Ross Sea inset correspond to Conductivity–Temperature–Depth profiler stations 81–86, used in Fig. 2. The red dots indicate the moorings shown in (b, c), and blue dots in the insets denote other available moorings. b, c Time series of temperature and velocity for moorings D1 (75 m above bottom (mab), Weddell Sea) and WC (20 mab, Ross sea), respectively. The thick black curve in (c) indicates the fitted daily tidal flow strength (see “Methods”), while the thick magenta curve indicates the daily minimum temperature. The correlation between the two curves is −0.8.
