The Chandra Deep Protocluster Survey: Lyα Blobs are powered by heating, not cooling
(2009-07-20)We present the results of a 400ks Chandra survey of 29 extended Ly-alpha emitting nebulae (Ly-alpha Blobs, LABs) in the z=3.09 proto-cluster in the SSA22 field. We detect luminous X-ray counterparts in five LABs, implying ... -
The Chandra Deep Protocluster Survey: Point-Source Catalogs for a 400 ks Observation of the z = 3.09 Protocluster in SSA22
(2009-07-24)We present X-ray point-source catalogs for a deep 400 ks Chandra ACIS-I exposure of the SSA22 field. The observations are centred on a z = 3.09 protocluster, which is populated by Lyman break galaxies (LBGs), Lyalpha ... -
Change Movers & Shakers, & Music Makers: Assessing the Feasibility of Introducing a Course on Music, the Environment, and Changemaking at Dalhousie University
(2018-04)Music, the environment, and changemaking are intrinsically linked. With anthropogenic climate change posing one of society’s most pressing issues, can this connection be used to inspire and inform a new generation of ... -
Changes in buoyancy and chemical composition during growth of a coastal marine diatom: Ecological and biogeochemical consequences
(1995)Growth and sinking of the coastal marine diatom Thalassiosira weissflogii was studied during experiments in a 2.1 m tall water column. Under nutrient-replete conditions, T. weissflogii grew rapidly in the upper layer of ... -

CHANGING TIDES AT DALHOUSIE UNIVERISTY
(2008-04)As a leading Canadian university in research and educational experience, the Greening the Campus Movement presents Dalhousie University with the opportunity to make new name for itself. Dalhousie has embarked on some ... -
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 ... -
Characteristics of predators and offspring influence nest defense by Arctic and Common Terns
(2000-05)Nest defense is a critical aspect of parental care that entails both costs and benefits. The purpose of this study was to examine patterns of nest defense in a colony of Arctic and Common Terns (Sterna paradisaea and S, ... -
Characterization of a large biogenic secondary organic aerosol event from eastern Canadian forests
(2010)Measurements of aerosol composition, volatile organic compounds, and CO are used to determine biogenic secondary organic aerosol (SOA) concentrations at a rural site 70 km north of Toronto. These biogenic SOA levels ... -
Characterization of Calcite Amygdules in Devonian Basalts, in the McArras Brook Formation, Nova Scotia
(2024-04)Along the North Shore of Nova Scotia, Canada vesicular basalts in the McArras Brook Formation are host to carbonate amygdules and veins. These basalts are interbedded within a well characterized Devonian strata but have ... -
Characterization of Extragalactic 24micron Sources in the Spitzer First Look Survey
(2004-09)In this Letter, we present the initial characterization of extragalactic 24um sources in the Spitzer First Look Survey (FLS) by examining their counterparts at 8um and R-band. The color-color diagram of 24-to-8 vs. 24-to-0.7um ... -
CHARACTERIZATION OF OUTBURST CHANNEL SANDSTONES IN THE PHALEN COLLIERY, CAPE BRETON, NOV A SCOTIA
(1997-04-15)The Phalen Colliery of New Waterford, Cape Breton, Nova Scotia is currently mining coal from the Phalen Seam of the Sydney Mines Formation, part of the offshore Carboniferous Sydney Basin. Since opening in 1984, the ... -
CHARACTERIZATION OF SEISMIC AMPLITUDE ANOMALIES AT HIBERNIA USING 3D SEISMIC DATA
(1998-04-15)The Chevron et al. Hibernia P-15 well penetrated one of many bright spots and encountered gas. Bright spots are one of four 'direct hydrocarbon indicators' and result from the high acoustic impedance contrast from gas ... -

Characterizing acid episode frequency, duration, and severity in Nova Scotia’s acidified streams
(2014-04)Acid episodes are a key factor in determining the state of freshwater ecosystems that have been chronically acidified by acid precipitation. An acid episode can be defined as a rapid drop in freshwater pH to well below ... -
CHARACTERIZING ICI&I TEXTILE WASTE IN HALIFAX, NOVA SCOTIA
(2018-04)Textile waste is growing problem around the world. Relative to other recyclable materials, textile waste management remains largely unexplored among industrialized countries, particularly for textile waste produced by ... -
Characterizing the Conifer Density Gradient from the Halifax Peninsula to the Hinterlands of the Halifax Regional Municipality
(2023-04)The urban-forest tree-species composition is influenced by the urban environment and thus by daily anthropogenic activity. However, in the naturalized woodlands, species composition is primarily influenced by natural ... -
Charting Future Ocean Law And Policy Directions; Examining Canada's Tools for Marine Protection Through Two Pacific Coast Case Studies
(2022-07-18)Much of Canada’s identity has been shaped by the important socio-cultural, economic, and recreational opportunities offered by the Atlantic, Pacific and Arctic oceans. However, continual growth in these areas are increasing ...
