Using a global positioning system to measure tidal currents in Absecon Inlet, Atlantic City, NJ

Journal of Surveying Engineering-Asce, 133(4): pp. 179-183.As a permit requirement for the development of a marina within Absecon Inlet, Atlantic City, NJ, tidal current measurements were required. Maximum ebb and flood currents determine the forces to which the structural elements of the marina will be subjected as well as sediment transport patterns near the marina. Currents also influence the maneuverability of small craft attempting to enter or exit the marina. Consequently, current velocities and directions during maximum ebb and flood tides (spring tides) were measured on 10 March 2005 in the vicinity of the proposed marina using the Global Positioning System (GPS). The location of the proposed marina in the inlet is shown in Figure 1. Current patterns are affected by the presence of Clam Creek (on southwest side of the study area) and the Route 87 Bridge over the inlet. The marina site is also subject to locally generated wind waves as well as waves entering the inlet from the Atlantic Ocean
