An abandoned marine sand-bar in the Cornwallis Valley, Nova Scotia
(McAlpine Publishing Co., Ltd., 1920) -
Biological processes and optical measurements near the sea surface: Some issues relevant to remote sensing
(1995)There is good evidence that bio-optical relationships are altered near the surface: (1) the fluorescence yield from chlorophyll declines, leading to bias in the estimation of pigment from fluorometry; (2) the modeled ... -
Carbon cycling in the Arctic Archipelago: the export of Pacific carbon to the North Atlantic
(European Geosciences Union, 2009-01)The Arctic Ocean is expected to be disproportionately sensitive to climatic changes, and is thought to be an area where such changes might be detected. The Arctic hydrological cycle is influenced by: runoff and precipitation, ... -
Circulation time, blood reserves and extracellular space in a cephalopod
(1984)Octopus vulgaris Cuvier has a fully enclosed blood system that includes large blood sinuses behind the eyes and around the gut. It would be useful to know the mean circulation time, the minimal number of heartbeats needed ... -
Compartmental models of nitrogen cycling in tropical and temperate marine environments
(1987)Time-course measurements of super(15)N tracer kinetics in particulate organic and in NH super(+) sub(4) pools from tropical and temperate regions were used to test several compartmental models describing the exchange of ... -
A description of water types on the Mackenzie Shelf of the Beaufort Sea during winter
(1992)For a number of years during the 1980s, observations of the physical and chemical properties of seawater in the southeastern Beaufort Sea have been acquired in late winter. The most complete data set, from 1987, has been ... -

Dissolved organic phosphorus concentrations in the northeast subarctic Pacific Ocean
(1992)Shipboard determinations of dissolved organic P (DOP) concentrations were made for NE subarctic Pacific Ocean samples with three different oxidation-hydrolysis methods: UV irradiation, acid persulfate digestion, and a ... -
Effect of the nonlinearity of the carbonate system on partial pressure of carbon dioxide in the oceans
(1995-04)Partial pressure of CO sub(2) is a nonlinear function of several seawater properties. Due to the nonlinearity in this relationship, the partial pressure of a uniform ocean would be different from that of a nonuniform ocean ... -
THE ESTUARINE AND EARLY MARINE SURVIVAL OF ATLANTIC SALMON: ESTIMATION, CORRELATES AND ECOLOGICAL SIGNIFICANCE
(2014-08-14)This thesis focuses on the estuarine, coastal and marine mortality of Atlantic salmon. The overall objective is to better understand the factors affecting the survival of Atlantic salmon during their early marine phase. ... -
Fatty acids as dietary tracers in benthic food webs
(Inter-Research, Nordbuente 23 Oldendorf/Luhe 21385 Germany, 2011)Fatty acid (FA) analysis is a well-established tool for studying trophic interactions in marine habitats. However, its application to benthic food webs poses 2 particular challenges. First, unlike pelagic zooplankton, ... -
Individual Variation in Migration Speed of Upriver-Migrating Sockeye Salmon in the Fraser River in Relation to Their Physiological and Energetic Status at Marine Approach
(University of Chicago Press, P.O. Box 37005 Chicago IL 60637 USA, [mailto:help@press.uchicago.edu], [URL:http://www.journals.uchicago.edu/], 2008)Little research has examined individual variation in migration speeds of Pacific salmon (Oncorhynchus spp.) in natural river systems or attempted to link migratory behavior with physiological and energetic status on a ... -
Inferred influence of nutrient availability on the relationship between Sun-induced chlorophyll fluorescence and incident irradiance in the Bering Sea
(American Geophysical Union, 2000 Florida Ave., N.W. Washington DC 20009 USA, [mailto:service@agu.org], [URL:http://www.agu.org], 2008-08)This study examines variability in the relationship between Sun-induced chlorophyll fluorescence and incident solar irradiance as a potential diagnostic of the nutritional status of phytoplankton. The study site is the ... -
Madden-Julian Oscillation and sea level: Local and remote forcing
(American Geophysical Union, 2010-01)The Madden-Julian Oscillation (MJO) is the dominant mode of atmospheric variability in the tropical atmosphere on intraseasonal time scales (i.e., weeks to seasons). This study examines the connection between the MJO and ... -
Mechanisms Influencing the Timing and Success of Reproductive Migration in a Capital Breeding Semelparous Fish Species, the Sockeye Salmon
(University of Chicago Press, P.O. Box 37005 Chicago IL 60637 USA, [mailto:help@press.uchicago.edu], [URL:http://www.journals.uchicago.edu/], 2009)Two populations of homing sockeye salmon (Oncorhynchus nerka; Adams and Chilko) were intercepted in the marine approaches around the northern and southern ends of Vancouver Island (British Columbia, Canada) en route to ... -
Modelling phase shifts in a rocky subtidal ecosystem
(Inter-Research, Nordbuente 23 Oldendorf/Luhe 21385 Germany, [mailto:ir@int-res.com], [URL:http://www.int-res.com/], 2008-03)The rocky subtidal ecosystem of the Atlantic coast of Nova Scotia is characterised by 2 community states, kelp beds and urchin barrens that alternate on a decadal time scale. While the shift from barrens to a kelp bed ... -
A modified galerkin-spectral model for three-dimensional, barotropic, wind-driven shelf circulation
(1993)The authors describe an efficient numerical scheme for calculating wind-driven currents on the continental shelf. Our scheme is based on the spectral approach introduced by Heaps and subsequently modified by Lardner. The ... -
A new measurement of CO sub(2) eddy flux in the nearshore atmospheric surface layer
(1991)Fluxes of CO sub(2) in the atmospheric surface layer have been measured at a shoreline site by the eddy correlation method using a new CO sub(2) sensor with greater sensitivity than the ones used in earlier studies. In ... -
