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 Land-use / Land Cover Change and Eutrophication in the Carleton River Watershed, Yarmouth County, Nova Scotia, Canada
(2018-04)A number of rivers and watershed systems in Southwestern Nova Scotia, Canada have experienced an increase in eutrophication promoting nutrients over the past three decades. As a consequence, artificial eutrophication and ... -
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). ... -
Quantifying the temporal and spatial variation of atmospheric particles on Dalhousie Campus – a pilot study
(2009-04)Outdoor air pollution is a broad and complicated issue that poses a real threat to human health and the environment. Past research demonstrates a link between urban air pollution and increased rates of mortality and morbidity ... -
A Quantitative Analysis of Deglaciation as a Possible Earthquake Mechanism in Canada.
(1985-04-15)With the exception of earthquakes occurring along the Pacific coast, earthquakes in Canada cannot be explained by plate tectonic theory. Deglaciation has been proposed as a possible cause of non-tectonic Canadian ... -
Quaternary and late Pliocene seismic stratigraphy of the central Scotian Slope
(2003-04-15)High resolution single channel seismic reflection profiles collected by the Geological Survey of Canada Atlantic (GSCA) have been used to define the Quaternary and Late Pliocene seismic stratigraphy of the central Scotian ... -
Quaternary Geologic History of Lady Franklin Bank, Southeastern Baffin Shelf, N.W.T.
(1983-04-15)The Lady Franklin Sand and Gravel is an informal term for a compositionally sand and/or gravel surficial sediment unit of the southeastern Baffin Shelf, delineated on the basis of grab samples and acoustic data by Praeg ... -
The Question of Relationship Between Low and High Grade Metamorphic Rocks in the French Mountain Area, of the Cape Breton Highlands, Nova Scotia
(1984-04-15)French Mountain in the Cape Breton Highlands of Nova Scotia is underlain by two broad metamorphic complexes: a metasedimentary complex and a composite gneiss complex. The metasedimentary complex, located on the southwestern ... -
Radiocarbon evidence for annual growth rings in the deep-sea octocoral Primnoa resedaeformis
(2005)The deep-sea gorgonian octocoral Primnoa resedaeformis is distributed throughout the Atlantic and Pacific Oceans at depths of 65 to 3200 m. It has a 2-part skeleton of calcite and gorgonin. Towards the inside of the axial ... -

(2012-03)As part of the suite of multidisciplinary investigations undertaken by the Ridge 2000 Program, new multichannel seismic studies of crustal structure were conducted at the East Pacific Rise (EPR) 8 degrees 20'-10 degrees ... -
Recommendations for promoting stair use in the Dalhousie Tupper Building
(2012-04)There is an increase in the proportion of people engaged in sedentary careers, which promotes a more inactive lifestyle. Promoting physical activity across Dalhousie campus is a major part of the Healthy Dalhousieʼs ... -
Reconstructing past sea surface temperatures near the Iceland-Faroe Ridge using alkenone paleothermometry (Uk’37 )
(2015-04)Understanding the ocean and its past behaviour is important because it gives insight into rates and amplitudes of global change. This thesis uses a paleoceanographic technique (Simplified Ketone Unsaturation Index (Uk’37)) ... -
