40Ar/39Ar Ages for the St. Anthony Complex Dynamothermal Aureole, Northwestern Newfoundland
(1981-03-15)A study of 40Ar/39Ar age relationships of various structural levels of the St. Anthony Complex dynarnothermal aureole was undertaken. Units of the aureole dated include a small jacupirangite suite metamorphosed with the ... -
When clean energy is dirty: A geospatial analysis of Canadian hydroelectric dams constructed between 1981 and 2011 and demographic indicators of environmental marginalization
(2022-08)The increasing urgency for climate action has pushed several governments towards investments in long-term, renewable energy sources. With its abundant supply of freshwater rivers, Canada’s shift away from oil and ... -
The equity of Toronto’s urban forest: Examining the relationship between urban forest change between 2008 and 2018, resulting tree frequency, and marginalization
(2022-08)Urban forests provide a myriad of social, environmental, and economic benefits that help make cities desirable and safe places to live. However, despite the widely acknowledged importance of urban forests, they are often ... -
EVALUATING PRESCHOOL CHIDLREN’S ENVIRONMENTAL KNOWLEDGE AND CONNECTION TO NATURE USING A GAMES TESTING TOOL
(2022-04)Establishing a connection to nature as a child is a necessity as it is crucial to enhancing children’s cognitive, attitudinal, emotional, and physical development (Driessnack 2009; Giusti et al. 2014; Bratman et al. 2015; ... -
PETROGRAPHY AND TRACE ELEMENT CHEMISTRY OF CALCITE VEINS IN THE DEEP DRILL 1972 DRILL CORE, BERMUDA ISLANDS
(2022-04)The Deep Drill 1972 drill core of the Bermuda Islands provides a representative sampling of Bermuda’s volcanic basement lithologies. Although there have been studies of the two primary lithologies over the past 50 years, ... -
TRACE ELEMENT GEOCHEMISTRY OF BIOTITE FROM THE SCRAG LAKE AND NEW ROSS PLUTONS OF THE SOUTH MOUNTAIN BATHOLITH, NOVA SCOTIA, CANADA: IMPLICATIONS FOR MAGMA DIFFERENTIATION
(2022-04)The South Mountain Batholith (SMB) is a 7300 km2, peraluminous, felsic intrusion occurring in SW Nova Scotia. The batholith consists of 13 plutons emplaced in two different phases between ~385 (Phase 1) and ~368 Ma (Phase ... -
Impacts of Forest Loss on the Global Water Cycle of the Permian-Triassic Extinction
(2022-04)Recent studies have shown profound effects of deforestation on decreased precipitation and evapotranspiration. This can be attributed to the concept of green water, which is the volume of water stored in soils and ... -
Dissolution features on diamonds from hypabyssal kimberlite facies and the effect of melt composition on diamond resorption
(2022-04)Diamonds can preserve features from their time deep in earth’s mantle and their ascent from the mantle to the Earth’s surface in hot kimberlite magma due to their high stability. The record of dissolution textures on ... -
Parental Factors That Affect the Connectedness to Nature of Pre-School Aged Children in Halifax, Nova Scotia
(2022-04)Time spent in nature has been found to promote a connectedness to nature (CTN) in both children and adults (Gifford & Nilsson, 2014; Deville, 2021). However, it has been found that people in North America are spending ... -
Evaluating the Historic Change in Per Capita Nominal Consumption of Animal Products in Canada Over the Past 60 to 100 years
(2022-03)Since the early 1960s, the global anthropogenic food systems have become incredibly resource intensive and have caused a global increase in greenhouse gas emissions, freshwater scarcity, land cover conversion, and biodiversity ... -
Characteristics of Metamorphic Textures of the Loch Eil Group of the Moine Highlands
(2022-04)Recent studies on the Moine supergroup suggests that ages over a large extent have been poorly constrained, and lack of research conducted is a result of structural complexity and mineralogical monotony. The purpose of ... -
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 ... -
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 ... -
