Coastal Groundwater Catchments Of The Gulf Of Alaska, Aeon Russo Sep 2021

Coastal Groundwater Catchments Of The Gulf Of Alaska, Aeon Russo

Masters Theses

High latitude mountain environments are experiencing disproportionately adverse effects in a currently changing climate. The Gulf of Alaska (GoA) region is an exemplar of this. Dramatic shifts are occurring in the region’s freshwater reservoirs as glaciers retreat more with each passing year. Research in the region places much focus on observing and predicting climate driven shifts in glacier mass balance, surface discharge, and associated nutrient fluxes to the ocean. On the other hand, coastal groundwater discharge (CGD) is given very little attention. Global and near-global estimates of CGD indicate variable results spanning an order of magnitude. Focusing on regionally specific …


The Role Of Vegetative Cover In Enhancing Resilience To Climate Change And Improving Public Health, Anastasia D. Ivanova Feb 2021

The Role Of Vegetative Cover In Enhancing Resilience To Climate Change And Improving Public Health, Anastasia D. Ivanova

Masters Theses

Changing temperature and precipitation patterns are causing degraded soil, water, and air quality which is negatively affecting the safety and health of people, and the productivity of urban and rural communities. However, research shows that implementing urban forests and cover crops into urban and rural landscapes, respectively, can mitigate these effects by providing ecosystem services. As extreme precipitation and heat events continue to intensify, there is a need for comprehensively assessing these ecosystem services under changing climates and for this information to be easily accessible by communities for rapid land-use decision making. Therefore, I investigated the role of urban forests …


Spatially-Resolved Integrated Precipitation-Surface-Groundwater Water Isotope Mapping From Crowd Sourcing: Toward Understanding Water Cycling Across A Post-Glacial Landscape, Allison Cole, David F. Boutt Jan 2021

Spatially-Resolved Integrated Precipitation-Surface-Groundwater Water Isotope Mapping From Crowd Sourcing: Toward Understanding Water Cycling Across A Post-Glacial Landscape, Allison Cole, David F. Boutt

Geosciences Department Faculty Publication Series

Isotopic analyses of delta O-18 and delta H-2 of water in the context of the hydrologic cycle have allowed hydrologists to better understand the portioning of water between the different water domains. Isoscapes on a large spatial scale have been created to show isotopic variation in waters as a function of elevation, temperature, distance to coast, and water vapor source. We present the spatial and temporal isotopic results of precipitation, surface water, and groundwater of an ongoing study across Massachusetts, USA in order to establish an isotopic baseline for the region. This represents one of the most comprehensive and detailed …


Anaerobic Membrane Bioreactors As A Treatment For Wastewater And Biogas Production At University Of Massachusetts Amherst, Marley Norton, Brady Bell, Ariel Fine Jan 2021

Anaerobic Membrane Bioreactors As A Treatment For Wastewater And Biogas Production At University Of Massachusetts Amherst, Marley Norton, Brady Bell, Ariel Fine

Student Showcase

Achieving carbon net neutrality at UMass by the year 2032 would require an unprecedented scale of renovation. However, we stand before an opportunity to set a nationwide standard in college campus sustainability. The usage of water also requires energy, as both are inextricable commodities, high in demand and often non-renewable. The central heating plant (CHP) distributes heat across the 1,400+ acre campus and consumes copious amounts of natural gas. A viable solution to relieving the dominant reliance on non-renewable energy without leaving the CHP as a stranded asset revolves around the implementation of a hybrid low temperature hot water system …
