Atlantic Ocean

Cape Cod and Cape Cod Bay (visible at the center of the image) can be seen in this generally south-looking view. Cape Cod is a narrow peninsula, glacial in origin, that is constantly changing as winds and water move sand along the shoreline. Cape Cod extends 105 km (65 mi) east and north into the Atlantic Ocean. A portion of Martha's Vineyard may be seen in the upper right corner of the image. Photo courtesy of NASA.
