Modeling Spatial Distributions Of Tidal Marsh Blue Carbon Using Morphometric Parameters From Lidar, Bonnie Turek

Masters Theses

Tidal marshes serve as important “blue carbon” ecosystems that accrete large amounts of carbon with limited area. While much attention has been paid to the spatial variability of sedimentation within salt marshes, less work has been done to characterize spatial variability in marsh carbon density. Driven by tidal inundation, surface topography, and sediment supply, soil properties in marshes vary spatially with several parameters, including marsh platform elevation and proximity to the marsh edge and tidal creek network. We used lidar to extract these morphometric parameters from tidal marshes to map soil organic carbon (SOC) at the meter scale. Fixed volume …

Why Massachusetts’ Drought Management Task Force Should Be In Statute: Drought Management Across The United States, Thomas G. Coughlin, Gabby Queenan

Student Showcase

This report explores structures and statutory authorities of Drought Management Task Forces across the United States, and particularly how different states have approached the issue of managing their respective Task Forces. There is growing interest in drought planning in the United States and worldwide.

As Massachusetts considers how to best respond to a new climate norm of short-term extreme droughts, one aspect of drought planning that is undergoing additional review is the role of the Massachusetts Drought Management Task Force, the state entity responsible for analyzing and reporting on drought conditions to the Secretary of Massachusetts Energy and Environmental Affairs …

The River Process Corridor: A Modular River Assessment Method Based On Process Units And Widely Available Data In The Northeast Us., John D. Gartner, Christine E. Hatch, Eve Vogel, Et. Al.

Water Reports

We define the river process corridor (RPC) as the area adjacent to a river that is likely to affect and be affected by river and floodplain processes. Here we present a novel approach for delineating the RPC that utilizes widely available geospatial data, can be applied uniformly across broad and multi-scalar spatial extents, requires relatively low levels of expertise and cost, and allows for modular additions and adaptations using additional data that is available in particular areas. Land managers are increasingly using a variety of delineated river and floodplain areas for applied purposes such as hazard avoidance, ecological conservation, and …

A Comparative Sustainability Study For Treatment Of Domestic Wastewater: Conventional Concrete And Steel Technology Vs. Vegetated Sand Beds (Vsb’S) And Their Relative Differences In Co2 Production, Alicia M. Milch

Masters Theses

Conventional wastewater treatment in the U.S. is an energy dependent and carbon dioxide emitting process. Typical mechanical systems consume copious amounts of energy, which is most commonly produced from fossil fuel combustion that results in the production of CO₂. The associated organic load is also metabolized by microorganisms into CO₂ and H₂O. As the desire to reduce CO₂ output becomes more prominent, it is logical to assess the costs of conventional treatment methods and to compare them to alternative, more sustainable technology. Vegetated Sand Bed (VSB) and Reed Bed (RB) systems are green technologies …

Syllabus: Sustainable Living: Solutions For The 21st Century, Lena Fletcher

Sustainability Education Resources

In this innovative interdisciplinary course you will work with your peers to research and understand how sustainability in different contexts presents solutions to many problems facing modern society. You will work in teams to investigate, evaluate, communicate, and reflect on the multifaceted challenges associated with natural resource use, food systems, energy, transportation, waste, the built environment, water quality, and climate change. You will also research case studies, debate controversies, assess political and cultural contexts, investigate technological advances, and identify gaps in scientific knowledge. Using these resources, you and your peers will be tasked with developing your own sustainable solutions for …
