Figure 7. Three-month running average (black line) and one-year low pass (blue line) for (a) ASPG, (b) zonally-averaged Gulf Stream (GS) mean path shift, (c) wind stress curl over the open ocean (see text), (d) eddy kinetic energy density (N-EKE) for SSHA>0 (see text) north of the GS mean path estimated from AVISO satellite geostrophic currents, (e) upstream transport, and (f) total river discharge along the east coast of America north of Cape Hatteras.

Figure 8. (a) The eddy kinetic energy density for SSHA>0 (see text) north of the Gulf Stream (NEKE; unit is m2s-2), averaged over the area west of 55W and from 1000m isobath south to the GS monthly mean path position. (b) The seasonal cycle of N-EKE.
