Circulation time, blood reserves and extracellular space in a cephalopod
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 ...
Effect of the nonlinearity of the carbonate system on partial pressure of carbon dioxide in the oceans
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 ...
Symmetry, change, perturbation, and observing mode in natural communities
Like a kaleidoscope, nature presents continuously fleeting images of natural communities. It has been difficult to discern patterns of community structure in these elusive images. For both theoretical and applied considerations, ...
Photosynthetic characteristics and estimated growth rates indicate grazing is the proximate control of primary production in the Equatorial Pacific
Macronutrients persist in the surface layer of the equatorial Pacific Ocean because the production of phytoplankton is limited. Measurements of photosynthesis as a function of irradiance (P-I) provide information on the ...
Spatial variation in right whale food, Calanus finmarchicus, in the Bay of Fundy
No abstract available.
Dissolved organic phosphorus concentrations in the northeast subarctic Pacific Ocean
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 ...
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:email@example.com], [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 ...
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 ...
A description of water types on the Mackenzie Shelf of the Beaufort Sea during winter
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 ...
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:firstname.lastname@example.org], [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 ...
