Emergent Behavior In A Coupled Economic And Coastline Model For Beach Nourishment, Eli D. Lazarus, D E. Mcnamara, M D. Smith, S Gopalakrishnan, A B. Murray Dec 2011

Emergent Behavior In A Coupled Economic And Coastline Model For Beach Nourishment, Eli D. Lazarus, D E. Mcnamara, M D. Smith, S Gopalakrishnan, A B. Murray

Publications

Developed coastal areas often exhibit a strong systemic coupling between shoreline dynamics and economic dynamics. "Beach nourishment", a common erosion-control practice, involves mechanically depositing sediment from outside the local littoral system onto an actively eroding shoreline to alter shoreline morphology. Natural sediment-transport processes quickly rework the newly engineered beach, causing further changes to the shoreline that in turn affect subsequent beach-nourishment decisions. To the limited extent that this landscape/economic coupling has been considered, evidence suggests that towns tend to employ spatially myopic economic strategies under which individual towns make isolated decisions that do not account for their neighbors. What happens …

Interannual Variability In American Lobster Settlement: Correlations With Sea Surface Temperature, Wind Stress And River Discharge, Mahima Jaini May 2011

Interannual Variability In American Lobster Settlement: Correlations With Sea Surface Temperature, Wind Stress And River Discharge, Mahima Jaini

Electronic Theses and Dissertations

Recruitment to benthic marine populations is fundamentally a biophysical problem. The American Lobster Settlement Index is an annual diver-based survey of the young-of-year American lobsters (Homarus americanus) found in inshore nurseries in New England, USA and Atlantic Canada at the end of the postlarval settlement season. The considerable interannual variability in the settlement index suggests that environmental factors play an important role in regulating planktonic larval supply and transport. In this study, I focused on the longest settlement time series from three oceanographically contrasting regions: Midcoast Maine, coastal Rhode Island and the lower Bay of Fundy. Sampling in these regions …

Building A Sustainable Seafood System For Maine, Robin Alden Jan 2011

Building A Sustainable Seafood System For Maine, Robin Alden

Maine Policy Review

In this article, Robin Alden notes that Maine could have one of the premier marine food systems in the world. However, that means adequate steward­ship of the Gulf of Maine ecosystem and diversifying the fishing industry beyond lobster by creating innovative public policy and a food system that supports community fishing.

Farms And The Working Landscape, John Piotti Jan 2011

Farms And The Working Landscape, John Piotti

Maine Policy Review

After years of losing farms and farmers, Maine is seeing an increase in the number of acres being farmed, due partly to a resurgence of interest in farming and new tools that help preserve working landscapes. These tools include agricul­tural easements such as those offered by the Land for Maine’s Future, the Buy/Protect/Sell program at Maine Farmland Trust, local ordinances, and several federal programs
