Nauset Marsh Trail Footbridge Temporary Closure After Labor Day
A small footbridge on the Nauset Marsh trail will be closed for repair for two weeks following Labor Day. Ask at the visitor center for detour information.
Sections of Boardwalk Closed at Red Maple Swamp Trail
Sections of the boardwalk at the Red Maple Swamp Trail have been closed due to structural deterioration and safety concerns. Check at Salt Pond Visitor Center for the current status of this trail, and for your safety, remain out of closed areas.

As the Aquatic Ecologist at Cape Cod National Seashore, I develop and implement monitoring and research in the park's freshwater kettle pond and estuarine ecosystems. Much of this work focuses on water quality issues and using field collected data to understand changes that are occurring in response to human uses and climate change. My research interests include terrestrial-aquatic couplings and the effects of anthropogenic activities on receiving ecosystems, specifically studying the effects of global change on water quality and macrophyte community dynamics and stable isotopic studies of nutrient sources, biological processes, and food web interactions.

Did You Know?
In 1990, an intense series of storms uncovered a prehistoric site on Coast Guard Beach in Eastham, MA. Archaeologists excavated the Carns Site, which was lived in by native peoples during the Early and Middle Woodland period, or approximately 2,100 to 1,100 years ago.
