The solar energy flux as a function of depth (the irradiance profile) in the ocean is an important function. It influences the dynamics of the mixed layer via the heat budget as well as the biology of the euphotic zone. The following three-parameter model can take into account the very...
Profiles of light transmission versus depth have been studied in the region of the Scotian Rise of the
North Atlantic at bottom depths between 4900 and 5000 m. A component model has been developed
and consists of three components of transmission which can be combined to duplicate accurately any
given...
Light transmission profiles have been used to study the optical properties of the suspended particles which are characteristic of the area of the Scotian Rise in the North Atlantic Ocean. This area is typified by very strong bottom currents and a highly variable bedform morphology. A good correlation (r =...
Measurements of total irradiance versus depth and beam transmission versus depth were made at
stations near shore along the west coast of the North and South American continents. The water types at
each station were optically classified according to the system of Jerlov (1976), thus providing additional
information for the...
Narrow angle light scattering measurements were made for various sizes of spherical particles suspended in water. These were compared to calculated theoretical scattering values as derived from the theory of Mie (1908). Through measurements with different particle concentrations at angles between 0.2° and 0.7° the effect of the unscattered main...
The objective of this paper is to look at past assessments and available data to examine the match (or mismatch) between university curricula and programs available to graduate students in the ocean sciences and the career possibilities available to those students. We conclude there is a need for fundamental change...
Macronutrients persist in the surface layer of the equatorial Pacific Ocean because the production of phytoplankton is limited; the nature of this limitation has yet to be resolved. Measurements of photosynthesis as a function of irradiance (P-I) provide information on the control of primary productivity, a question of great biogeochemical...
Children’s behavioral self-regulation and executive function (EF; including attentional or
cognitive flexibility, working memory, and inhibitory control) are strong predictors of
academic achievement. The present study examined the psychometric properties of a
measure of behavioral self-regulation called the Head-Toes-Knees-Shoulders (HTKS) by
assessing construct validity, including relations to EF measures, and...
