Mercy Hall 102 | 207-893-7978 |

Teaches Environmental and Marine Sciences courses including Ecology and the Environmental Challenge, the Environmental Seminar and Aquaculture: Science and Methods and Senior Research.

Scholarly Interests – Marine geochemistry, ocean acidification, climate change impacts on marine ecosystems; Aquaculture techniques and production.

Mark Green has received a $419,000 National Science Foundation grant to continue his research on two commercially valuable clam species in nearby Casco Bay. The three-year grant, which is the second Dr. Green has received from the National Science Foundation, will include fieldwork along the shoreline in Freeport and South Portland.

Professor Green teaches Limnology, Chemical Oceanography, Geological Oceanography, Introduction to Environmental Science, and Senior Research. His academic interests are in marine and lacustrine biogeochemistry.

With his National Science Foundation grant, Professor Green discovered why juvenile clams die in large numbers in Casco Bay, Maine. In the process, he disproved a longstanding theory about clam predators, and gave environmental science students valuable experience as research assistants and co-authors of journal articles.

His other primary field location is Sebago Lake, where his research focus is on the cycling of silica to and from sediments, and the interaction between iron and arsenic in deep-lake sediments. Professor Green’s personal interests are his wife and children, his dogs, and fishing.

“While Basket Island Oyster company has been around for about 10 years, originally as a hobby farm started by St. Joseph’s College professor of natural sciences Mark Green, it has surged as a commercial enterprise in the last four years. Hubacz was one of Green’s students at St. Joseph’s and after graduating in 2009 stayed on as a lab technician, assisting Green with an aquaculture class, among others.”
