STS068-173-106 Delaware Bay and Southern New Jersey, New Jersey, U.S.A. October 1994 Because of the small scale and low oblique look angle of this northeast view of Delaware Bay and southern New Jersey, none of the infrastructure that is associated with urban development can be identified in this picture that includes Dover and Wilmington Delaware, Philadelphia, Pennsylvania; and Camden and Atlantic City, New Jersey. Notice the almost straight line (northeast-southwest alignment) along the New Jersey coast that separates the barrier island beaches from the elevated, forested lands (dark region) towards the interior. These beaches are continuously subjected to erosion and reshaping. The coastal barrier beach is a classic example of an extensive sandy beach (light colored area) immediately adjacent to the Atlantic Ocean. Heading inland from the beach there is a sequence of sand dunes, elevated barrier flats, lower salt marshes, and finally many lagoons before reaching the elevated forested lands. The Delaware River, which serves as the state boundary between Pennsylvania and New Jersey, can be traced as it flows northeasterly until it reaches Trenton, New Jersey where it makes a 90 degree turn to the northwest.
