Water Chemistry Dynamics In Four Vernal Pools In Maine, Usa, Lydia H. Kifner

Electronic Theses and Dissertations

Vernal pools are small seasonal wetlands that are a common landscape feature that contribute to biodiversity in northeastern North American forests. However, even basic information about their biogeochemical functions, such as carbon cycling, is limited. Dissolved gas concentrations (CH₄, CO₂) and other water chemistry parameters were monitored weekly at the bottom and surface of four vernal pools in central and eastern Maine, USA, from April to August 2016. The vernal pools were supersaturated with respect to CH₄ and CO₂ at all sampling dates and locations. Concentrations of dissolved CH₄ and CO₂ ranged …

River Restoration: Institutions, Boundaries, And Social Ecological Dynamics, Eileen Sylvan Johnson

Electronic Theses and Dissertations

This human dimensions research, consisting of three manuscripts, explores the social and ecological dimensions of river restoration through an examination of the restoration trajectories of the Androscoggin, an impaired system, and the Kennebec, a restored system. Manuscript one examines the influence of biophysical and community attributes and institutional rules on policy stakeholders goals and actions within the two watersheds. For manuscripts one and two, we conducted semi-structured interviews with key informants, assembled documents pertaining to restoration actions, and conducted participant observation at stakeholder meetings. We qualitatively analyzed transcripts and documents. Results suggest that policy stakeholders’ understandings of biophysical and community …

Lake Site Assessments: Us Epa Time-New England Lakes, Sarah J. Nelson, Adam Baumann, Alesha Coffin, Ken Johnson, Catherine Schmitt, Kristin Strock

Forest Resources Faculty Scholarship

TIME (Temporally Integrated Monitoring of Ecosystems) is a statistically selected population of lakes in New Eng- land and the Hudson Valley (31 lakes) and the Adirondacks (43 lakes) that were selected from the original 1991 EMAP-SW (Environmental Monitoring and Assessment Program–Surface Waters) population with acid neutralizing capacity less than 100 meq/L (Young & Stoddard 1996). Samples are taken annually, during a summer base-flow ‘index period’. This sampling strategy is used to reduce hydrologic impact on water chemistry and hence provide an assessment of trends in chemistry with the least number of samples (e.g., Stoddard et al. 2003).

The EMAP program …

An Engineering, Economic, And Political Approach To Beach Erosion Mitigation And Harbor Development: A Review Of The Beach Communities Of Camp Ellis, Maine, Wells, Maine, And Cape May, New Jersey, Edmund Cervone

Electronic Theses and Dissertations

The history of coastal engineering projects is fraught with problems. In this thesis I examine the federal navigation project at Wells, Maine. In Wells, an incomplete understanding of the coastal setting led to a faulty engineering design responsible for a poorly functioning inlet and harbor and damage to neighboring beaches and wildlife habitat. Project planners and designers did not account for all unforeseen problems that arose. Reviewing the history of Wells Harbor demonstrates how proper attention to the natural setting, economics, and the political environment is essential to a successful project and enables agencies and stakeholders better to address contingencies …

“A Last Chance For Wilderness”: Defining The Allagash Wilderness Waterway, 1959-1966, Richard W. Judd

Maine History

Seen in national perspective, the Allagash Wilderness Waterway is arguably Maine's most dramatic environmental accomplishment. The waterway resulted from an extended debate over several mutually exclusive proposals for the north Maine woods— dams to flood it; national parks to preserve it; and recreational schemes to transform it into a Coney Island of the North. In the mid-1960s, a coalition of landowners and conservationists cobbled together a preservation plan that conformed to the 1968 Federal Wild and Scenic River Act but pioneered several unique features that gave the wilderness idea a decidedly “eastern” twist. As a result, the waterway became a …
