Fig. 3: Observations and simulations of the Weddell Sea overflow.
From: Circum-Antarctic bottom water formation mediated by tides and topographic waves
a Historical mooring locations, with colored dots representing different sets of moorings. Arrows indicate time-averaged flows close to the sea floor. The light purple and red shadings on the continental slope indicate the approximate spatial ranges of topographic Rossby waves (TRWs) with different frequencies (see (b, d)). b Power spectral density (PSD) of velocity for several representative moorings shown in (a). c A snapshot of vertically integrated tracer concentration in the Weddell-like model simulation, with the arrows at 300 mab (meters above bottom) denoting the circulations of TRWs. The colored pentagons indicate the sites used for spectral analysis in (d). d PSD of velocity for the selected sites shown in (c). Note the different y-axis range from (b). e Cross-slope/vertical distribution of potential temperature along the section indicated by the blue dashed line in (c).
