Predicting the frequency of storm surges and extreme sea levels in the northwest Atlantic
(2006-10)[1] A 40 year hindcast of storm surges in the northwest Atlantic and adjacent shelf seas is performed using a 2-D nonlinear barotropic ocean model forced by realistic 6 hourly winds and air pressures. This hindcast is used ... -
Predicting wave dislodgment of mussels: variation in attachment strength with body size, habitat, and season
(2001)Breaking waves impose large hydrodynamic forces which may dislodge mussels and other organisms living on exposed rocky shores. We examined the effect of variation in attachment strength with size, habitat and season on ... -
Prediction of surface currents and drifter trajectories on the inner Scotian Shelf
(2003-09)The predictive skill of a simple model of surface flow on the Scotian Shelf is assessed using oceanographic data collected in February 1996. The model is forced by wind stress, water density, and sea level along the open ... -
Preferential recycling of nutrients - the ocean's way to increase new production and to pass nutrient limitation?
(1999-12)Uptake of atmospheric CO2 by the oceans and the export of carbon into deeper waters via the biological CO2 pump is driven by the production of particulate organic matter (POM). The elemental ratios of carbon, nitrogen, and ... -
Preliminary observations of the status of shallow water reefs at Sandy Island, Carriacou, Grenada
(1996-10-29)Sandy Island is an uninhabited cay lying off the west coast of Carriacou. Surrounded by clear waters and coral reefs, with an extensive white sand beach and quiet water on its south side and a palm canopy on the island, ... -
Preparation and Characterization of Bxc1-X Thin-Films with the Graphite Structure
(1992-07)No abstract available. -
Preparation of Low Surface Area Si-Alloy Anodes for Li-Ion Cells by Ball Milling
(The Electrochemical Society, 2022-06-22)A new and simple 2-step milling technique is utilized to produce Si–Ti–N alloys with significantly reduced surface area compared to conventional ball milling, while still attaining a full amorphous active Si phase. Surface ... -
A Pressure Modulator Radiometer for Measuring Stratospheric Trace Gases
(1989-11)No abstract available. -
Pressure-Induced Isostructural Antiferromagnetic-Ferromagnetic Transition in an Organic Electride
(American Chemical Society, 2018) -
Prevalence and evolution of core photosystem II genes in marine cyanobacterial viruses and their hosts
(2006-08)Cyanophages ( cyanobacterial viruses) are important agents of horizontal gene transfer among marine cyanobacteria, the numerically dominant photosynthetic organisms in the oceans. Some cyanophage genomes carry and express ... -
Prey Exchange Rates and the Impact of Predators on Prey Populations in Streams
(1990)We present four lines of evidence that the magnitude of prey exchange (=immigration/emigration) among substrate patches has an overwhelming influence on the perceived effects of predators on prey populations. (1) An extensive ... -
The Price of Gold: An Analysis of the Financial Costs of LEED Certification and the Role of LEED in Meeting Dalhousie’s Sustainability Objectives
(2016-04)The Leadership in Energy and Environmental Design (LEED) Green Building Rating System, now plays a major part in the design process of many major construction projects. Dalhousie University is no exception, having a ... -
The Price of Plastic: An Analysis of the Environmental and Economic Impacts and Social Perceptions of Single-Use Plastic Containers at Dalhousie University
(2019-04)While recyclable, landfills house 22 to 43% of plastics (Gourmelon, 2015, p. 2). Plastic packaging comprises the majority of plastic waste (Brooks et al., 2018, p. 1). With rises in plastic production (Gourmelon, 2015, ... -
Primary production by suspended and benthic microalgae in a turbid estuary: Time-scales of variability in San Antonio Bay, Texas
(1996-12)The within-day, between-day and month-to-month variability of light attenuation and microalgal chlorophyll a (chl a) and photosynthetic response was measured in San Antonio Bay, Texas, USA. Waters were shallow (<2 m) ... -
Primary Production Estimates from Recordings of Solar Stimulated Fluorescence in the Equatorial Pacific at 150-Degrees-W
(1992-01)Biological, optical, and hydrographical data were collected on the WEC88 cruise along 150-degrees-W and during a 6-day time series station on the equator during February/March 1988. This area was characterized by a subsurface ... -
Primiparous and multiparous females differ in mammary gland alveolar development: implications for milk production
(2012-08)Mammary gland capacity is influenced by the number of secretory cells in the gland, the activity of those cells and the size and arrangement of the alveoli that they form. Although reproductive experience has been shown ...
