Upper Carboniferous Fluvial Sedimentation in the Gulf of St. Lawrence Coal Basin, Mabou Mines, Nova Scotia
(1986-04-15)Mabou Mines is located on the northwestern coast of Cape Breton Island, Nova Scotia. Steeply dipping sedimentary strata of the Upper Carboniferous Pictou Group (dated as Late Westphalian C) are exposed on the shoreface. ... -
An upper limit to [C II] emission in a z ~= 5 galaxy
(2005-05-01)Low-ionization-state far-infrared (FIR) emission lines may be useful diagnostics of star-formation activity in young galaxies, and at high redshift may be detectable from the ground. In practice, however, very little is ... -
Upper Paleozoic Alluvial Plain Sedimentation in the Morien Group, Eastern Cape Breton, Nova Scotia
(1984-04-15)A section of upper Morien strata located near the western margin of the Sydney Basin was examined. Three sub-assemblages of sedimentary facies were recognized: Thick bedded sandstone characterized by a fining-up ... -
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 ...
