URANIUM, RADIUM, AND RADON IN STREAMS, DOMESTIC WELL WATERS, AND SOILS: A GIS ANALYSIS OF GEOLOGICAL, GEOCHEMICAL, AND GEOPHYSICAL RELATIONSHIPS
(1999-04-15)Elevated levels of 238Uranium (U) and its daughter products 226Radium (Ra) and 222Radon (Rn) in groundwater, surface water, and soils have the potential of posing health risks. In particular, high levels of radioactive ... -
Urban Forests: Reintroducing Native Species to Dalhousie University Campus.
(2009-04)Urban forests are an important part of the community and people should aspire to maintain them in the same way they maintain their cars, homes and lawns. The benefits of an urban forest on campus are massive. The trees ... -
Urban surface water runoff on Dalhousie University’s Studley campus (Halifax, N.S.)
(2017-03)As an urban environment continues to grow and densify, consequences such as increased surface water runoff become ever more prominent as urban landscapes seal off previously permeable surfaces. Stormwater management ... -
The use and value of opportunistic sightings for cetacean conservation and management in Canada
(2019-12)Twenty-one marine mammal species are designated under the Species at Risk Act (SARA) in Canada. When species are designated under SARA, management plans, recovery strategies, and action plans are outlined to prevent wildlife ... -

The use of ecosystem service valuation in environmental sensitivity analysis for ship-source oil spill preparedness and response planning in Chedabucto Bay, Nova Scotia
(2015-03-09)A recent decision was made by the Government of Canada to bring its national ship-source oil spill preparedness and response regime up to world-class standards. This signaled the movement away from an approach that uses ... -
Use of F-BODIPYs as a protection strategy for dipyrrins: optimization of BF2 removal.
(Journal of Organic Chemistry, 2012)We recently reported the first general method for the deprotection of 4,4-difluoro-4-bora-3a,4a-diaza-s-indacenes (F-BODIPYs) involving a microwave-assisted procedure for the removal of the BF2 moiety, and liberation of ... -
USE OF FORAMINIFERA AND THECAMOEBIANS AS RELIABLE INDICATORS OF MARINE/FRESHWATER TRANSITION ZONES IN SOUTHERN FLORIDA
(2001-04-15)The mangrove environment of Southern Florida is expansive, dominating the much of the southern coastline, including that of the southwestern Everglades. As such, it is a dynamic environment that is constantly readjusting ... -
The Use of Tin (IV) Chloride to Selectively Cleave Benzyl Esters over Benzyl Ethers and Benzyl Amines
(Canadian Journal of Chemistry, 2014)Benzyl esters are cleaved upon reaction with SnCl4, resulting in isolation of the corresponding carboxylic acid. Importantly, benzyl ethers, amines and amides do not undergo debenzylation under these conditions, nor do a ... -
Using [CI] to probe the Interstellar Medium in z~2.5 Sub-Millimeter Galaxies
(2013-07-24)We present new [CI](1-0) and 12CO(4-3) Plateau de Bure Interferometer observations of five Sub-Millimeter Galaxies (SMGs) and combine these with all available [CI](1-0) literature detections in SMGs to probe the gas ... -
Using Adaptive and Fisheries Management to Increase MPA Success: A Case Study of the Gilbert Bay MPA [graduate project].
(2016)The Gilbert Bay Marine Protected Area (MPA) was established in 2005 with the purpose of conserving the genetically discrete Gilbert Bay cod subpopulation. However, following the implementation of the MPA the cod subpopulation ... -
Using minimum bootstrap support for splits to construct confidence regions for trees

Using SCUBA to place upper limits on arcsecond scale CMB anisotropies at 850 microns
(1999-09-19)The SCUBA instrument on the James Clerk Maxwell Telescope has already had an impact on cosmology by detecting relatively large numbers of dusty galaxies at high redshift. Apart from identifying well-detected sources, such ... -
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 ... -
Using small, temporary seismic networks for investigating tectonic deformation: Brittle deformation and evidence for strike-slip faulting in Bhutan
(2007-07)We processed data from a small, five-station temporary seismic network deployed from January 2002 until March 2003 within the Kingdom of Bhutan. We detected, associated, and located approximately 2,100 teleseismic, regional, ...
