Distributions of Pigments and Primary Production in a Gulf-Stream Meander
An investigation was made of physical effects of Gulf Stream meandering on the vertical and horizontal distributions of photosynthetic pigments and primary production. Cruises were conducted in the vicinity of a meander ...
Thorium sorption in seawater suspensions of aluminium oxide particles
(Pergamon, Oxford, 1993-05)
A comparison of the experimental results, in which (super 234) Th was used as a tracer of Th, with relationships predicted by surface complexation models, shows that Th sorption in the Al (sub 2) O (sub 3) suspensions was ...
Condition, Buoyancy and the Distribution of Larval Fish - Implications for Vertical Migration and Retention
A Lagrangian time-stepping model driven by water density, daytime larval feeding and swimming, and by condition-related larval buoyancy was used to track the vertical position and condition of individual larval cod (Gadus ...
Synchrony of Recruitment Across the North-Atlantic - an Update - (Or, Now You See It, Now You Dont)
About 20 years ago, Garrod and Colebrook, and Templeman, proposed that recruitment of marine fish in the North Atlantic was controlled by environmental factors that extended across the ocean basin. As evidence, they reported ...

Development of Convection in a Rotating Fluid - Scales and Patterns of Motion
Laboratory observations of thermal convection in a rotating system are described. In our rotating table experiments, an initially steady, unstratified fluid is subjected to a buoyancy flux over a limited region of a ...
Identifying overturns in CTD profiles
The authors purpose a scheme to test whether inversions in CTD density profiles are caused by overturning motions (from which mixing rates may be inferred) or by measurement noise. Following a common practice, possible ...
Fluxes through diffusive staircases: a new formulation
Deals with two aspects of the flux law for diffusive convection: (1) the dependence on density ratio, and (2) the dependence on T. Empirical formulations of the dependence of temperature and salinity fluxes on density ratio ...
Salt finger signatures in microstructure measurements
By measuring the `scaled dissipation ratio' , which is the relative magnitude of the dissipation of thermal variance compared with the dissipation of turbulent kinetic energy, one can distinguish between salt fingering and ...
A Physical Estimate of New Production in the Equatorial Pacific Along 150-Degrees-W
New production was estimated for the equatorial Pacific by quantifying the supply of nitrate into the euphotic zone. The turbulent flux of nitrate, estimated by assuming gradient transport and by direct measurements of ...
