Access at seashore locations
The stairs at Nauset Light Beach in Eastham are closed due to storm damage. Herring Cove North Lot in Provincetown sustained damage resulting in closure of multiple parking spaces. The Nauset Marsh Trail bridge was destroyed in a 2012 storm. More »
Cape Cod National Seashore and the surrounding communities rely solely on groundwater as their source of freshwater. In addition, the hydrological processes associated with groundwater have a great deal of ecological bearing on ponds, streams, and other wetland and terrestrial systems throughout the Seashore. Thus, it is not difficult to understand the importance of groundwater as a resource on the Outer Cape.
The groundwater of the Outer Cape consists of four distinct flow lenses, all of which are surrounded on the sides and underneath by saltwater. This area where the two layers meet is known as the freshwater/saltwater interface and its position and movement due to a variety of stressors (e.g. sea-level rise) is of particular interest to scientists.
A systematic protocol has been developed and implemented to monitor groundwater over the long-term at the Seashore. Currently, the effort includes collecting data from 30 observation wells and 10 ponds on a regular basis. This comprehensive approach has been implemented to provide an integrated assessment of water resources. The network of sampling locations has been established taking into account a variety of different factors including spatial distribution, anticipated changes to hydrodynamics, and impacts of development within all four of the ground-water-flow cells, or lenses, in the Seashore area. The monitoring protocol was developed with the intent of being used as a standard throughout the region at other coastal parks and refuges. The long-term approach is essential in order to understand the complex dynamic of hydrological change on aquatic, terrestrial, and estuarine ecosystems and on water supplies.

The word “cranberry” originated as a contraction of crane berry, a name given to the plant by early settlers because the flower resembles the head of a crane.
