T jpo, 2011, in press he origin of along-shelf pressure gradient in the Middle Atlantic Bight

Figure 3. (a) 16-year mean SSH (contours; interval = 0.005 m on shelves, but = 0.05m elsewhere). (b) The mean SSH at stations (red dots in (a)) along the 50 m isobath with distance measured from the southernmost location near Cape Hatteras. Symbols are, CHS: Chesapeake Bay, DEL: Delaware Bay, ELS: east end of Long Island, and CC: Cape Cod. The solid line indicates a linear regression from DEL to ELS, and the dash line indicates a linear regression from CHS to CC. (c) Time series of along-shelf pressure gradient fluctuations (mean is removed). The time tick marks indicate January 1^st.
