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 ...
Seven case studies in sustainable agriculture
(Science Council of Canada, Ottawa, 1991-05-24)
Seven case studies of SA (sustainable agriculture) in Canada were conducted in the late fall/early winter of 1990/91. The primary objective was to provide examples of innovative SA practices that have been implemented by ...

Variations in heat flow across the Goban Spur and Galicia Bank continental margins
(1991)
Presents the results of 44 new heat flow stations which were taken in 1984 and 1989 in profiles across the Goban Spur and Galicia Bank continental margins (NE Atlantic Ocean). Simple extensional models indicate that the ...
Patch Dynamics of a Phytophagous Mite Population Effect of Number of Subpopulations
(1991)
I conducted a field test of the hypothesis that the dynamics of a predator-prey interaction should be affected by the number of interacting subpopulations within an assemblage. I used a "successful" biological control ...
Phytoplankton Growth and Light-Absorption as Regulated by Light, Temperature, and Nutrients
(1991-12)
Numerous studies of the growth of phytoplankton in the laboratory have demonstrated the dependence of cellular pigment concentration and growth rate upon light intensity, photoperiod, temperature, and nutrient supply. These ...
Hypotheses to Explain High-Nutrient Conditions in the Open Sea
(1991-12)
Oceanic high-nutrient, low-chlorophyll waters are characterized principally by the persistence of major nutrients at the sea surface. This condition indicates control of autotrophic production by something other than NO3 ...
Measuring the Geometric Component of the Transition-Probability in a 2-Level System
(1991-04)
We describe the measurement of a component of the nonadiabatic transition probability in a
two-level system that depends only on the path through parameter space followed by the Hamiltonian,
and not on how fast the path ...
An Observational Study of the Energy-Transfer between the Seasonal Mean Flow and Transient Eddies
(1991-03)
The large-scale energetics of the Northern Hemisphere atmospheric motions are computed in the frequency domain using a 5-year data set from the ECMWF operational analyses. The geographical distributions of kinetic energy ...
