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 …

Photodissolution Of Sedimentary Organic Matter, Lawrence M. Mayer

University of Maine Office of Research Administration: Grant Reports

The field of marine photochemistry has previously focused on dissolved organic matter and trace metals. However, recent studies have shown that sediment suspensions in the ocean are also affected by sunlight and have the potential to dissolve most of their particulate organic carbon to the dissolved organic phase.

A researcher from the University of Maine will determine the importance of photodissolution in the coastal Louisiana area, where riverine particulates are quickly deposited in shallow waters. Optical properties of the particulates will be examined to assess the photon fluxes and to determine the quantum yields of this photodissolution reaction. To determine …

Marine Sciences Faculty Scholarship

Can there ever be a truly sustainable deep-sea fishery and if

so, where and under what conditions? Ecosystembased

fisheries management requires that this question be

addressed such that habitat, bycatch species, and targeted

fish populations are considered together within an ecosystem

context.

To this end, we convened the first workshop to develop an

ecosystem approach to deep-sea fisheries and to ask whether

deep-sea species could be fished sustainably. The workshop

participants were able to integrate bycatch information into

their framework but found it more difficult to integrate other

ecosystem indicators such as habitat characteristics.
