Figure 3: Vertical sections on southeastern and northwestern flanks of the AC.
From: Observing mesoscale eddy effects on mode-water subduction and transport in the North Pacific
The southeastern and northwestern sections (thick black lines in Fig. 2g,l) are in the circumferential tangent direction of the AC. Vertical sections along (a,b) the southeast (SE) and (c,d) the northwest (NW) tracks for March to April, based on (a,c) the 17 Argo floats and (b,d) the eddy-resolving OFES (Methods). The horizontal ordinate is the distance from the southernmost point. The time-depth sections averaged along the (e) southeastern and (f) northwestern tracks are shown in the lower tow panels. Black contours denote potential density, thickened to highlight the 25.0 and 25.5 kg m−3 isopycnals that correspond to the top and bottom of the STMW layer, respectively. Coloured shades denote PV (10−10m−1s−1), and vectors in b,d show the along-track flow.
