Endangered Whales Still Get Tangled In Fishing Gear: Let’S Change The Way We Approach The Problem, Tora Johnson

Maine Policy Review

The Gulf of Maine lobster industry has been roiled by conflict over whale entanglement for decades. With fewer than 350 North Atlantic right whales remaining, federal regulators are again seeking to implement new measures to protect them from tangling in fishing gear, while the lobster industry faces myriad challenges. My 2005 book Entanglements examined the complex and fraught debate between whale advocates and fishermen. Each side believed the other was inherently evil, greedy, and unduly powerful. Of course, the truth lay somewhere between. Between them were the brave souls who went to sea to wrestle fishing gear off of entangled …

Scaling Up The Relevance Of Land-Sea Connections In Coastal Bacteria Pollution Vulnerability, Bea E. Van Dam

Electronic Theses and Dissertations

Bacteria pollution closures of Maine’s coastal shellfish harvest areas have substantial negative consequences for coastal businesses and communities. Sustainability solutions for Maine’s shellfish harvesting areas and businesses require new types of knowledge and information to protect water quality and public health while avoiding unnecessary fishery closures. Coastal management agencies have interests in tools to support science-based management decision-making related to pollution and sustainability solutions for businesses and communities.

Prior research into land-sea connections has demonstrated uses of geographic information and statistical methods to facilitate management and science communication. Research in Maine has focused on identification and comparison of attributes influencing …

Including The Human Dimension Into Resilience Planning For Maine’S Lobster Fishery, Katherine Maltby, Katherine E. Mills

Maine Policy Review

The American lobster fishery is one of the most valuable in the US but is being affected by climate-driven shifts in lobster availability, impacting people’s ability to harvest the resource and sparking broader adaptation challenges. Since the late 1990s, lobster landings in the Gulf of Maine (GOM) have climbed to record levels while those in Southern New England (SNE) have experienced significant declines. The experiences of SNE lobstermen during these declines can offer important lessons for both individual lobstermen and communities in the GOM, where lobster abundance is currently at high levels but facing future uncertainty given continuing climate trends. …

Quantifying Spatial Heterogeneity Of Wild Blueberries And Crop Water Stress Monitoring Using Remote Sensing Technologies, Kallol Barai

Electronic Theses and Dissertations

The wild blueberry is one of the major crops of Maine, with significant economic value and potential health benefits. Due to global climate change, drought impacts have been increasing significantly in recent years in the northeast region of the USA, causing significant economic losses in the agricultural sectors. It has been predicted to increase further in the future. Changing patterns of the elevated atmospheric temperatures, increased rainfall variabilities, and more frequent drought events have made the wild blueberry industry of Maine vulnerable, suggesting the adoption of novel approaches to mitigate the negative impacts of global climate changes. Also, wild blueberry …

Covid-19 And Outdoor Recreation In Maine And New Hampshire: Analysis Of Trends Using Passive Visitation Data, Andrea Knapp

Honors College

The COVID-19 pandemic has motivated alterations to the way people approach and practice outdoor recreation. Access to outdoor areas has changed rapidly in response to measures like travel bans, closures, and health and safety guidelines. Recreation managers have had to act quickly to keep up with these visitor use fluctuations in order to protect resources from use degradation. I explored how pandemic effects have changed visitation behaviors and trends in outdoor recreation in Acadia National Park and the White Mountain National Forest. Acadia National Park is a well-known and highly trafficked outdoor recreation area with over 3 million visits annually …

Climate Care: Pathways For Coastal Community Resilience, Jessica Reilly-Moman

Electronic Theses and Dissertations

Climate change increasingly impacts coasts worldwide. The ability of coastal ecosystems and the human communities who are part of them to absorb disturbance and maintain function or transform, or resilience, is of critical importance to managing these impacts. However, to date, climate resilience largely has focused on biophysical impacts and technocratic solutions, while issues of social and environmental justice and human well-being become more acute and entrenched. Consequently, I ask: How can coastal communities cope with climate change? To answer this question, I leverage traditional, emergent, and novel social research methods in Mexico, Central America, and Maine. Using ethnography, interviews, …

Using Photovoice To Navigate Social-Ecological Change In Coastal Maine: A Case Study On Visibility, Visuality, And Visual Literacy, Kevin P. Duffy

Electronic Theses and Dissertations

Media representations of the environment support specific cultures of viewing that can create expectations about how to observe social-ecological interactions in everyday life. While public perceptions may appear, in some cases, to reflect these normative representations, more critical and participatory approaches to environmental research and management have begun to complicate these representations as they are negotiated through intrapersonal, interpersonal, and group communication. Working from a visual cultural approach that interrogates issues of visibility, visuality, and visual literacy, this dissertation theorizes how coastal residents represent their own observations and experiences of environmental change through photography and what impact their views have …

To Know The Land With Hands And Minds: Negotiating Agricultural Knowledge In Late-Nineteenth-Century New England And Westphalia, Justus Hillebrand

Electronic Theses and Dissertations

Ever since the eighteenth century, experts have tried to tell farmers how to farm. The agricultural enlightenment in Europe marked the beginning of a long arc of new experts aiming to change agricultural knowledge and practice. This dissertation analyzes the pivotal period in the late nineteenth and early twentieth century in Germany and the United States when scientists, improvers, and market agents began to develop comprehensive ways to communicate agricultural innovation to farmers. In a functional approach to analyzing the negotiation of agricultural knowledge through its communication in things, words, and practices, this dissertation argues that the process of change …

Surface Network Extraction From High Resolution Digital Terrain Models, Eric Guilbert

Journal of Spatial Information Science

A surface network is a topological data structure formed by a set of thalwegs and ridges on a digital terrain model. Its computation relies on the detection of saddles on the terrain. Hence, computation methods must guarantee enough saddles are detected but also that no improper conflicts between ridges and thalwegs are created, leading to an inconsistent network. This paper presents a new approach that maximizes the number of saddles and ensures this topological consistency for high-resolution terrain models represented by a raster grid. The grid is triangulated in order to preserve saddles and to facilitate thalweg and ridge computation. …

Examining Satellite Images Market Stability Using The Records Theory: Evidence From French Spatial Data Infrastructures, Chadi Jabbour, Anis Hoayek, Pierre Maurel, Zaher Khraibani, Latifa Ghalayini

Journal of Spatial Information Science

The spatial data infrastructures (SDIs) which constitute a direct link between spatial data users and the large Earth observation industry, have a leading role in establishing market opportunities in the space sector. The spatial information supplied through various forms of SDI platforms exhibits large increases in demand volatility. The users' demand is unpredictable and the market is vulnerable to high evolution shifts. We study the effect of extreme demands for a particular type of spatial information, the satellite images. Drawing on two French SDIs, GEOSUD and PEPS, we examine the shifts occurring on their platforms and assess the probability of …

Towards Detecting, Characterizing, And Rating Of Road Class Errors In Crowd-Sourced Road Network Databases, Johanna Guth, Sina Keller, Stefan Hinz, Stephan Winter

Journal of Spatial Information Science

OpenStreetMap (OSM), with its global coverage and Open Database License, has recently gained popularity. Its quality is adequate for many applications, but since it is crowd-sourced, errors remain an issue. Errors in associated tags of the road network, for example, are impacting routing applications. Particularly road classification errors often lead to false assumptions about capacity, maximum speed, or road quality, possibly resulting in detours for routing applications. This study aims at finding potential classification errors automatically, which can then be checked and corrected by a human expert. We develop a novel approach to detect road classification errors in OSM by …

The Holocaust In Białystok: Urban, Rural, And Forest Environments As Spaces Of Resistance, Survival, And Persecution, Dakota Gramour

Electronic Theses and Dissertations

During the German occupation of Poland in World War II, thousands of Jews escaped city or ghetto life by seeking refuge within rural villages or fleeing to the forests. Numerous factors shaped individual survivor experiences within these spaces. In particular, gender, age or familial status, environmental factors like weather conditions or terrain, as well as personal politics and language or technical skills, all molded how one could act or was forced to react in these spaces. This study emphasizes the unique two-way relationships between experience and three kinds of environments found in the Białystok District: the city of Białystok, small …

Service Quality Monitoring In Confined Spaces Through Mining Twitter Data, Mohammad Masoud Rahimi, Elham Naghizade, Mark Stevenson, Stephan Winter

Journal of Spatial Information Science

Promoting public transport depends on adapting effective tools for concurrent monitoring of perceived service quality. Social media feeds, in general, provide an opportunity to ubiquitously look for service quality events, but when applied to confined geographic area such as a transport node, the sparsity of concurrent social media data leads to two major challenges. Both the limited number of social media messages--leading to biased machine-learning--and the capturing of bursty events in the study period considerably reduce the effectiveness of general event detection methods. In contrast to previous work and to face these challenges, this paper presents a hybrid solution based …

The Impact Of Urban Road Network Morphology On Pedestrian Wayfinding Behaviour, Debjit Bhowmick, Stephan Winter, Mark Stevenson, Peter Vortisch

Journal of Spatial Information Science

During wayfinding pedestrians do not always choose the shortest available route. Instead, route choices are guided by several well-known wayfinding strategies or heuristics. These heuristics minimize cognitive effort and usually lead to satisfactory route choices. Our previous study evaluated the costs of four well-known pedestrian wayfinding heuristics and their variation across nine network morphologies. It was observed that the variation in the cost of these wayfinding heuristics increased with an increase in the irregularity of the network, indicating that people may opt for more diverse heuristics while walking through relatively regular networks, and may prefer specific heuristics in the relatively …

How Does Socio-Economic And Demographic Dissimilarity Determine Physical And Virtual Segregation?, Michael Dorman, Tal Svoray, Itai Kloog

Journal of Spatial Information Science

It is established that socio-economic and demographic dissimilarities between populations are determinants of spatial segregation. However, the understanding of how such dissimilarities translate into actual segregation is limited. We propose a novel network-analysis approach to comprehensively study the determinants of communicative and mobility-related spatial segregation, using geo-tagged Twitter data. We constructed weighted spatial networks representing tie strength between geographical areas, then modeled tie formation as a function of socio-economic and demographic dissimilarity between areas. Physical and virtual tie formation were affected by income, age, and race differences, although these effects were smaller by an order of magnitude than the geographical …

Modelling Orebody Structures: Block Merging Algorithms And Block Model Spatial Restructuring Strategies Given Mesh Surfaces Of Geological Boundaries, Raymond Leung

Journal of Spatial Information Science

This paper describes a framework for capturing geological structures in a 3D block model and improving its spatial fidelity, including the correction of stratigraphic, mineralisation and other types of boundaries, given new mesh surfaces. Using surfaces that represent geological boundaries, the objectives are to identify areas where refinement is needed, increase spatial resolution to minimise surface approximation error, reduce redundancy to increase the compactness of the model and identify the geological domain on a block-by-block basis. These objectives are fulfilled by four system components which perform block-surface overlap detection, spatial structure decomposition, sub-blocks consolidation and block tagging, respectively. The main …

Big Issues For Big Data: Challenges For Critical Spatial Data Analytics, Chris Brunsdon, Alexis Comber

Journal of Spatial Information Science

In this paper we consider some of the issues of working with big data and big spatial data and highlight the need for an open and critical framework. We focus on a set of challenges underlying the collection and analysis of big data. In particular, we consider 1) inference when working with usually biased big data, challenging the assumed inferential superiority of data with observations, n, approaching N, the population n -> N. We also emphasise 2) the need for analyses that answer questions of practical significance or with greater emphasis on the size of the effect, rather than the …

Route Schematization With Landmarks, Marcelo De Lima Galvao, Jakub Krukar, Martin Noellenburg, Angela Schwering

Journal of Spatial Information Science

Predominant navigation applications make use of a turn-by-turn instructions approach and are mostly supported by small screen devices. This combination does little to improve users' orientation or spatial knowledge acquisition. Considering this limitation, we propose a route schematization method aimed for small screen devices to facilitate the readability of route information and survey knowledge acquisition. Current schematization methods focus on the route path and ignore context information, specially polygonal landmarks (such as lakes, parks, and regions), which is crucial for promoting orientation. Our schematization method, in addition to the route path, takes as input: adjacent streets, point-like landmarks, and polygonal …

Local Modelling: One Size Does Not Fit All, A. Stewart Fotheringham

Journal of Spatial Information Science

This editorial piece considers what happens when we abandon the concept that models of social processes have global application in favor of a local approach in which context or the influence of 'place' has an important role. A brief history of this local approach to statistical modelling is given, followed by a consideration of its ramifications for understanding societal issues. The piece concludes with futures challenges and prospects in this area.

Indigeneity And Spatial Information Science, Matt Duckham, Serene Ho

Journal of Spatial Information Science

Spatial information science has given rise to a set of concepts, tools, and techniques for understanding our geographic world. In turn, the technologies built on this body of knowledge embed certain ways of knowing." This vision paper traces the roots and impacts of those embeddings and explores how they can sometimes be inherently at odds with or completely subvert Indigenous Peoples' ways of knowing. However advancements in spatial information science offer opportunities for innovation whilst working towards reconciliation. We highlight as examples four active research topics in the field to support a call to action for greater inclusion of Indigenous …

Inferring Movement Patterns From Geometric Similarity, Maike Buchin, Carola Wenk

Journal of Spatial Information Science

Spatial movement data nowadays is becoming ubiquitously available, including data of animals, vehicles and people. This data allows us to analyze the underlying movement. In particular, it allows us to infer movement patterns, such as recurring places and routes. Many methods to do so rely on the notion of similarity of places or routes. Here we briefly survey how research on this has developed in the past 15 years and outline challenges for future work.
