Figure 5. (a) 16-year (1993-2008) mean and variance ellipses of depth-averaged currents along the 50 m isobath; (b) 3-month running averaged time series of the ASPG (of fig.3c+the mean) estimated along the 50 m isobath; (c) 3-month running averaged time series of depth-averaged along-shelf current averaged along the 50 m isobath from Delaware to the east end of Long island (see Fig.3). The mean is 0.025 m s-1 towards the southwest. Tick marks on (b) and (c) show January.
Figure 6. The linear best-fit of 16-year mean SSH vs. distance between DEL and ELS for the 8 numerical experiments in Table 1, computed as in Fig. 3b. The slopes represent the mean ASPGs. Their values are listed in Table 1. Symbols DEL: Delaware Bay, and ELS: eastern Long Island. For clarity, the y-scale has been shifted so that SSH = 0 at x = 450km (near New Jersey).
