Have you ever gazed out over the beautiful estuary of the North River and wondered how it all formed, and how it has changed?

This field trip, with NSRWA’s own Sara Grady, Ph.D. and UMass Amherst Research Professor Brian Yellen Ph.D., will familiarize participants with the amazing story of salt marsh resilience in the North and South Rivers estuary. We will visit a series of sites that illustrate how the beach and salt marsh formed and how they have evolved in response to sea level rise and the Portland Gale of 1898, which reconfigured the estuary’s geography. We will also take a sediment core in the North River salt marsh and look at what the layers of sediment can tell us about marsh’s response to sea level rise.

Join us on Saturday, May 21 from 1:00-3:30pm as we visit 3 locations around the watershed. Brian Yellen has been studying hydrology and sediment transportation around the North River and has made some surprising discoveries about marsh composition and processes. He, and NSRWA Ecologist Sara Grady, will provide information about the North and South Rivers as well as hold a Q&A session at each location.

We will be visiting 3 sites. The sites are in order as follows:

  1. Rexhame Beach – 325 Standish St., Marshfield, MA
  2. Marshfield Recreation Department – 900 Ferry St., Marshfield, MA
  3. Damon’s Point – 299 Damons Point Rd. Marshfield, MA

Meet at Rexhame Beach parking area at 1:00pm.

Appropriate footwear is recommended. Carpooling is encouraged.

This event is free. Families welcome. No dogs please.
