(1985-04-15)A red bed unit in the Late Pennsylvanian Morien Group at Waddens Cove, Cape Breton County, Nova Scotia, occurs stratigraphically between the fine upper Morien Group and the coarse lower Morien Group. A succession of sandstone ... -
A Seismostratigraphic Analysis of High Resolution Seismic Reflection Data from the Western Grand Banks of Newfoundland
(1985-04-15)A seismostratigraphic analysis of data from the western Grand Banks of Newfoundland has enabled the definition of seven acoustic units. Units were defined on the basis of high resolution, seismic reflection profiles, airgun ... -
A Refraction Seismic Survey of Martinique Beach: Geometry and Significance to Barrier Beach Evolution
(1985-04-15)During the summer of 1984 a refraction seismic survey was conducted at Martinique Beach using a 12 geophone array and seismic recorder with a hammer plate as the acoustic source. Sixteen sites were occupied along the 3.5 ... -
The Analysis of High Resolution Shallow Seismic Reflection Data from Sable Island Bank
(1985-04-15)This project involves the analysis of high resolution shallow seismic reflection profiles collected on the south flank of Sable Island Bank. The objective of this study is to gain an understanding of the genesis and sediment ... -
Micro-petrological Analysis of Shergottite Meteorite North West Africa 4468
(2019-04-15)This study investigates the chemical variations within mineral phases in the Martian meteorite sample North West Africa (NWA) 4468. Meteorites are the only samples of Martian rocks that can be studied directly. Their ... -
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 ... -
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 ... -
Quantifying the Causes of Human-Black Bear Conflicts in Nova Scotia
(2021-04)Black bears are curious and will stop at nothing for a good meal. Unfortunately, Nova Scotian residents are seeing an increase in the presence of black bears around their properties and homes (Parsons pers. com., 2020). ... -
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 ... -
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 ... -
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 ... -
When and Where Can Farm-level Life Cycle Assessments be Used to Predict Aggregate Food System Contributions to Global Warming?
(2021-04)Food production is a key anthropogenic system driving global warming, biodiversity loss, land use change, and biogeochemical cycle disruption. Food system sustainability is a field of research dedicated to addressing ... -
Experimental study of reaction textures in volcaniclastic kimberlites
(2019-04-15)Some of the most famous diamond deposits are associated with Kimberly-type pyroclastic kimberlite facies (KPK) located within diatreme part of kimberlite pipes. The origin of this type of kimberlite is one of the most ... -
Magnetic Modelling in the Davis Strait and Northern Labrador Sea
(1986-04-15)The Davis Strait is a constricted passage lying between Baffin Island and Greenland. Davis Strait separates the waters of Baffin Bay and the Labrador Sea. There have been disagreements as to the nature of the crust in ... -
