QUANTIFYING IMPACTS OF SPATIAL RESOLUTION ON PIXEL AND OBJECT-BASED METHODS OF IMAGE CLASSIFICATION: A CASE STUDY OF IDENTIFYING ESTUARINE MORPHOLOGY IN COBEQUID BAY, NOVA SCOTIA, CANADA
(2020-04-15)
Image processing methods can be used to classify land cover and phenomena fromsatellite imagery according to their spectral characteristics and identify target features. These methodscanprovide a relatively efficient ...
Geological controls on radon concentration in surficial sediment in Whitehorse, Yukon
(2021-04-15)
Indoor concentrations of radon gas in excess of HealthCanada guidelines have been reported throughout the Whitehorse area, yet only cursory measurements have been made to determine the concentration of radon in undisturbed ...
THE STRENGTH EVOLUTION OF A CRUSTAL SCALE SHEAR ZONE
(2020-04-15)
The brittle-ductile transition zone, thelocation of greatest strength in the crust,can be determined through the construction of a stress profilewith depth. The profile is constrained from the calculated flow stresses for ...
Understanding Resistance to Flood Risk Mapping: A Test of Climax Thinking in Southwestern Nova Scotia
(2021-04)
As a result of climate change, flooding is projected to become more severe and
frequent. Flood risk mapping delineates areas of past and potential future flooding, and allows
for informed decision-making regarding personal ...
Examining the effectiveness of municipal reuse centers in Nova Scotia: Benefits and Best Practices
(2021-04)
One of the major environmental challenges of today is the overconsumption of resources and excessive waste. Municipal reuse centers offer a potential solution, as they work to extend the lifespan of objects otherwise ...
The effect of call similarity on call discrimination by Tree Swallow (Tachycineta bicolor) nestlings in the presence of noise
(2021-04)
As the extent of noise expands with urbanization, so does the extent of its impacts on
wildlife. The impact of noise is particularly strong when it comes to the disruption of avian
communication. Birds rely heavily on ...
Examining the Impact of the National Arts Centre’s Climate Cycle Initiative on the Environmental Knowledge, Attitudes, and Professional Practices of Canadian Theatre Artists
(2021-04)
The current literature on the role of the Arts in sustainability suggests that environmental themes introduced in different forms of art (i.e. theatre, sculpture, music) can change the way people feel about environmental ...
Compound Specific Isotope Analysis of Invertebrate Tissues: Determining Nitrogen Variability in Coastal Nova Scotia
(2020-05-15)
Anthropogenic nitrogen (N) loading in coastal marine environments causes eutrophication,
alters food web structures, and degrades water quality. In Nova Scotia,
anthropogenic N sources are introduced to coastal waters ...
The effect of a weakening Atlantic Meridional Overturning Circulation on ocean temperatures in the Gulf of St. Lawrence over the past 150 years
(2021-04-15)
Ocean circulation is essential for transporting heat, dissolved CO2, and nutrients all around the globe. The strength of the ocean circulation, therefore, has a major influence on climate and vice versa. Over time, ocean ...
Using Seismic Noise to Monitor COVID-19 Societal Response in Halifax
(2022-04)
Seismometers record signals from more than just earthquakes. Cultural noise, high-frequency seismic noise generated from human activities (e.g., traffic) produces a distinct diurnal signature in frequencies above 1 Hz due ...
