Call for Presenters, responses due 1/20

MassBays is teaming up with the National Park Service, Northeastern University, and UMass Boston to host a Boston Harbor and Islands Science Symposium April 11-12, 2017.

Consider presenting your research and/or program information to an audience including professional scientists, resource managers, students, and citizen scientists.

We're interested in highlighting citizen science and student work as well!

Proposals for presentations of any format are welcome -- submit your ideas by January 20th
January 25:  Lecture, Gypsy moths and drought, Norwell
February 1:  Lecture, Swimming with sharks and sea turtles, Norwell
February 8:  Lecture, Local shipwrecks and underwater artifacts, Norwell
February 15:   Lecture, A year hiking the Bay Circuit TrailNorwell
February 22: Lecture, South Shore sea and sand from the sky, Norwell
February 22: Lecture, MantaRay - Advancing Research on Marine Debris, Marblehead

Sea Level Rises...

and Massachusetts communities plan for the future

Municipalities have access to more and more resources -- information, technical support, and funding -- to assess and respond to impacts of climate change. 

Over the past two months, MassBays has helped to convene events on the Upper North Shore, South Shore, and Cape Cod, bringing together decisionmakers and scientists to share those resources. Presentations from those events are available online:

Great Marsh Sea Level Rise Symposium, November 6, 2016
South Shore Sea Level Rise Symposium, December 1, 2016
4th Annual Cape Coastal Conference, December 6-7, 2016   

Registration is also open now for a Massachusetts Sustainability Conference in Beverly on March 17th. The event is sponsored by Massachusetts Sustainable Communities and Campuses, Salem Sound Coastwatch, and Endicott College, and will include a range of topics relevant to businesses, state and local agencies, and education administrators.

Feel free to contact your MassBays Regional Coordinator if you need help sparking action in your own community.

Goodbye, Tack Factory Dam

In December MassBays South Shore Regional Coordinator Sara Grady (right) and Massachusetts Rivers Alliance Director Julia Blatt (also a member of MassBays' Management Committee, at left) joined Division of Ecological Restoration staff at the site of the Tack Factory Dam in Norwell. With the dam's removal, herring swimming up Third Herring Brook will have 8.4 more miles to explore this Spring! Check out North and South Rivers Watershed Association's time-lapse video of the dam removal.

Sources of turbidity in Salem Harbor

Citizen monitoring has documented increased turbidity in Salem Harbor over the past decades – causing concern that the cloudy water conditions are reducing the amount of light that reaches seagrass, increasing water temperature, clogging fish gills, and smothering fish eggs and larvae.

MassBays, the Massachusetts Environmental Trust, and the National Science Foundation provided funding to Salem State University researchers and Salem Sound Coastwatch to determine the source(s) of particulate matter in the Harbor. The team deployed monitoring buoys, analyzed suspended sediment samples, and cross-referenced meteorological data over 2 years (2012-2014).

In a peer-reviewed paper published in this month in the journal Science of the Total Environment, Brad Hubeny and colleagues report that “[r]esults reveal a complex system in which multiple sources are associated with particulate matter. Weight of evidence demonstrates that phytoplankton productivity in the water column, however, is the dominant source of particulate matter associated with elevated turbidity in Salem Harbor.” Riverine inputs and resuspension of harbor sediments around boat moorings contributed to a lesser extent.
