Submergence of the New Jersey Coast.

A series of five radiocarbon dates obtained from samples taken along the base of the lagoon between the Brigantine City Barrier and the mainland indicates a rate of submergence of 3 meters per millennium between 6090 and 2600 years before the present. During the last 2600 years the average submergence has slowed down to only 1.2 to 1.4 meters per millennium; the general picture of a rapid rise and the subsequent slackening is in agreement with results published for the New England area.
