The Eelgrass Group and the Shellfish Survey Group are joining forces to become
Low Tide Benthic Research
led by Susan Bryant and Dr. Sara Grady.
Eelgrass Project
The eelgrass project started as a seaperch robotics project with Laura Humphrey and has evolved each year. In 2017 we used ARCGIS to record densities, patchiness, bottom type, tunicates and wasting disease, and in the lab measured these features along with # of leaves, length, width and reproductive shoots. We took underwater GoPro footage, observations by wading, floating, and snorkeling. We present our findings annually at CSCR's early spring State of the Watershed Event, and at Zosterapalooza, a conference held in Boston by Phil Colarusso and the Environmental Protection Agency. We are thrilled to discuss our work with other researchers and local residents. Contact
Shellfish Project
Cohasset harbor estuary has a history of shellfishing, but also an ebb and flow of varieties.  The inner harbor and Cohasset side of the channel are currently closed to shellfishing, and we will explore why and whether they should remain closed, and whether there are indications that ecologically-based aquaculture could thrive here.  We may experiment with growing shellfish from spat, and what grows naturally on docks and in mud. We will also explore the little known benthic organisms, that form the base of many of our local foodchains. They live in the decaying remains of all that has fallen into the estuary over the centuries aka mud.  As the Harbor Committee and Municipal Vulnerabilities Preparedness Program consider plans to address sealevel rise, participants in this project will contribute unique insight on these issues.  We will explore the shellfish survey, begun in the Gulf River thanks to the generosity of the Gulf Association, as well as benthic studies of the past, and present our findings at the State of the Harbor and other public forums.
Schedule & How to Join
Activities will be scheduled around the tides and can be found on this calendar. (Let Susan know if this doesn't work for you). We welcome people to jump in (literally and figuratively) on the days that they can, and ask questions of the other students to get up to speed, and contribute. By the end of the summer you will have experience in these fields that few others do, and will be able to present unique insight from our estuary to other researchers and planners.  
High School students should register as regular CSCR members.  To get up-to-the-minute info on our daily weather-dependent schedule, and to let us know you plan to attend on any given day, students should sign up for REMIND (send a text message to the number 81010 that says "@cscr"). You may also contact us at or 857-231-1768.  
Bring swimming gear, watershoes, sun protection, a towel, and a change of dry clothes. Your own snorkel gear, gopros, phones with waterproofing, clam rake, or laptop are also welcome.
