Estimating Surficial Seafloor Sediment Properties Using An Empirical Orthogonal Decomposition On Acoustic Backscatter Waveform Properties, Joshua Lincoln Humberston

Master's Theses and Capstones

Seafloor classification and environmental assessment in shallow marine waters are crucial to habitat mapping, coastal management policies and maintaining navigational waterways. There are existing methods for remotely estimating some bottom properties, but the large variety of desired measured sediment properties frequently leads to insufficient quantifiable data to support marine policy decisions. This problem is exacerbated by the highly variable bottom composition of typical coastal and estuarine environments. In this work, field observations from an Odom Echotrac vertical-incidence echosounder with a 200 khz transducer were used to estimate seafloor sediment characteristics in regions with variable bottom types. Observations were obtained in …

Non-Industrial Private Forest Landowner Engagement And Amenity- Driven Migration In Wildfire-Prone Landscapes Of The Inland Northwest, Morgan Ann Crowley

Master's Theses and Capstones

Rural counties in the Inland Northwest have a ‘working lands’ culture that supports livelihoods dependent on the health of wildfire-prone private and public forests. Wildfires threaten economic livelihoods and exacerbate the challenges of working landscapes impacted by changing economies, demographic trends, and forest conditions. The main objectives of this thesis are to investigate: 1) what comprises amenity-driven migration and how are amenity- driven migration and wildfire severity related?; 2) are amenity-driven migrants engaged in forest management activities in Wallowa County, Oregon and what is forest management engagement?; 3) how does landowner parcel proximity from WUI, USFS land relate to perspectives …

Space Use And Habitat Affinities Of The Singing Vole On The Northern Foothills Of The Brooks Range, Alaska, Andrew Maguire

Master's Theses and Capstones

Arctic tundra is being affected by a rapidly warming climate, which is accompanied by shifts in plant community composition and structure. Shrub expansion, a predominant consequence of this warming, is linked with changes in nutrient cycling and has direct implications to global change biology. Habitats are being altered across the landscape, with subsequent changes to arctic faunal communities. While herbivory has been noted as important in contributing to plant community composition in the arctic, with the potential to both exacerbate and mitigate shifts toward shrub-dominated tundra landscapes, little research has been conducted on herbivore dynamics. Microtine rodents (i.e., voles and …

A New Approach To Climate Change: A Consideration Of Ancillary Benefits In Linking Regional Permit Trading Systems, William H. Meyer

Honors Theses and Capstones

In this paper, I investigate the economic efficiency of two major approaches to greenhouse gas reduction, and evaluate their respective benefits. First, I trace the path of action and thinking on addressing climate change from a global to a regional level. Second, I consider the major economic benefits of having a globally-integrated greenhouse gas abatement system. Third, I consider the economic benefits of regional approaches to climate change, with a focus on the ancillary benefits from greenhouse gas abatement. I conclude by reviewing the challenges to linking regional abatement systems into a cohesive network, and suggest a potential future approach …

Life Cycle Assessment (Lca) Of Tourism Activities, Kayla Santello

Honors Theses and Capstones

Abstract— Tourism, like other developed industries is a commerce that requires energy inputs and yields outputs with significant effects on the environment. However a comprehensive study examining the life cycle impact associated with each tourism component including transportation, accommodation, food services, and recreation is still lacking. Therefore a search of previous tourism life cycle studies was carried out and ten studies were further investigated. Indicators, assessment approaches, and system boundaries of these previous studies were assessed. Then the outcomes were normalized and compared in order to obtain ranges for the four components of tourism. It was found that energy intensity …

Sources Of Uncertainty In Estimating Stream Solute Export From Headwater Catchments At Three Sites, Ruth D. Yanai, Naoko Tokuchi, John L. Campbell, Mark B. Green, Eiji Matsuzaki, Stephanie N. Laseter, Cindi L. Brown, Amey S. Bailey, Pilar Lyons, Carrie R. Levine, Donald C. Buso, Gene E. Likens, Jennifer D. Knoepp, Keitaro Fukushima

New Hampshire EPSCoR

Uncertainty in the estimation of hydrologic export of solutes has never been fully evaluated at the scale of a small-watershed ecosystem. We used data from the Gomadansan Experimental Forest, Japan, Hubbard Brook Experimental Forest, USA, and Coweeta Hydrologic Laboratory, USA, to evaluate many sources of uncertainty, including the precision and accuracy of measurements, selection of models, and spatial and temporal variation. Uncertainty in the analysis of stream chemistry samples was generally small but could be large in relative terms for solutes near detection limits, as is common for ammonium and phosphate in forested catchments. Instantaneous flow deviated from the theoretical …

Validation Of Satellite Rainfall Products For Western Uganda., Jeremy E. Diem, Joel N. Hartter, Sadie J. Ryan, Michael W. Palace

Geography

Central equatorial Africa is deficient in long-term, ground-based measurements of rainfall; therefore, the aim of this study is to assess the accuracy of three high-resolution, satellite-based rainfall products in western Uganda for the 2001–10 period. The three products are African Rainfall Climatology, version 2 (ARC2); African Rainfall Estimation Algorithm, version 2 (RFE2); and 3B42 from the Tropical Rainfall Measuring Mission, version 7 (i.e., 3B42v7). Daily rainfall totals from six gauges were used to assess the accuracy of satellite-based rainfall estimates of rainfall days, daily rainfall totals, 10-day rainfall totals, monthly rainfall totals, and seasonal rainfall totals. The northern stations had …

Climate warming is projected to affect forest water yields but the effects are expected to vary. We investigated how forest type and age affect water yield resilience to climate warming. To answer this question, we examined the variability in historical water yields at long-term experimental catchments across Canada and the United States over 5-year cool and warm periods. Using the theoretical framework of the Budyko curve, we calculated the effects of climate warming on the annual partitioning of precipitation (P) into evapotranspiration (ET) and water yield. Deviation (d) was defined as a catchment's change in actual ET divided by P …

Energy Input Is Primary Controller Of Methane Bubbling In Subarctic Lakes, Martin Wik, Brett F. Thornton, David Bastviken, Sally Macintyre, Ruth K. Varner, Patrick M. Crill

Faculty Publications

Emission of methane (CH4) from surface waters is often dominated by ebullition (bubbling), a transport mode with high‐spatiotemporal variability. Based on new and extensive CH4 ebullition data, we demonstrate striking correlations (r2 between 0.92 and 0.997) when comparing seasonal bubble CH4 flux from three shallow subarctic lakes to four readily measurable proxies of incoming energy flux and daily flux magnitudes to surface sediment temperature (r2 between 0.86 and 0.94). Our results after continuous multiyear sampling suggest that CH4 ebullition is a predictable process, and that heat flux into the lakes is the dominant driver of gas production and release. Future …

Conserving Wetlands For Humans And Amphibians: A Multidisciplinary Approach To Understanding The Social And Ecological Effectiveness Of New England's Wetland Policies, Jessica Veysey Powell

Doctoral Dissertations

Freshwater wetland ecosystems are a valuable resource, but current policies fail to prevent their continuing destruction. Policy-makers increasingly use decentralized wetland-buffer programs to address such policy failings, but scant research has evaluated whether these programs are both ecologically and socially effective. In the following dissertation, I address this gap using two complementary projects.

For the first project, I assessed whether forested buffers are an effective tool for maintaining viable populations of pool-breeding amphibians. Such species spend their early life stages in vernal pools, which are small, highly productive wetlands, but use the surrounding forest during juvenile and adult life-stages. Though …

Securitize Me: Stimulating Renewable Energy Financing By Embracing The Capital Markets, Andrew C. Fink

The University of New Hampshire Law Review

The current system of financing renewable energy projects is broken and inadequate, especially when compared to the framework for participating in oil and gas ventures. The solution lies in borrowing accepted energy business practices and adapting them to solar and wind energy projects. This Article focuses on the current issues facing renewable energy project financing in the United States, analyzes failed attempts to stimulate growth, and presents the securitization of renewable energy assets as a solution. Drawing on current legal structure and debates from the corporate sphere, this Article also discusses specific securitization techniques that can help to democratize and …

Multiyear Measurements Of Ebullitive Methane Flux From Three Subarctic Lakes, Martin Wik, Ruth K. Varner, David Bastviken

Faculty Publications

Ebullition (bubbling) from small lakes and ponds at high latitudes is an important yet unconstrained source of atmospheric methane (CH4). Small water bodies are most abundant in permanently frozen peatlands, and it is speculated that their emissions will increase as the permafrost thaws. We made 6806 measurements of CH4 ebullition during four consecutive summers using a total of 40 bubble traps that were systematically distributed across the depth zones of three lakes in a sporadic permafrost landscape in northernmost Sweden. We identified significant spatial and temporal variations in ebullition and observed a large spread in the bubbles' CH4 concentration, ranging …
