The Role Of The Higher Shelf Modes In Coastal Hydraulics, Roger L. Hughes Jan 1987

The Role Of The Higher Shelf Modes In Coastal Hydraulics, Roger L. Hughes

Journal of Marine Research

A simple barotropic model is used to establish the basic nature of the hydraulics of the various shelf modes in coastal flows. It shows that there is a major difference in behavior between flows with an even number of subcritical modes and those with an odd number of subcritical modes. It is suggested that a poleward flowing western boundary current exhibiting an odd number of subcritical shelf modes loses contact with the coast at that latitude at which the flow becomes critical to the next higher shelf mode. The East Australian Current and the East Cape Current are discussed as …


Solutions For Internal Tidal Generation Over Coastal Topography, P. D. Craig Jan 1987

Solutions For Internal Tidal Generation Over Coastal Topography, P. D. Craig

Journal of Marine Research

Internal tides may be described by a hyperbolic equation which, for the case of constant buoyancy frequency, has constant coefficients. The equation is solved by using the characteristic geometry and characteristic functions to establish a set of linear algebraic equations in the modal amplitudes. The accuracy of the solutions can be assessed using energy considerations. The capability of the solution technique is demonstrated by simulating the barotropic generation of internal waves over linear topography, with emphasis on near-critical topography, when the solution exhibits high shears and discontinuous behavior at the critical slope. The structure of the waves is determined by …


Compositional Changes In Particulate Matter On The Iceland Rise, Through The Water Column, And At The Seafloor, M. J. Richardson, C. D. Hollister Jan 1987

Compositional Changes In Particulate Matter On The Iceland Rise, Through The Water Column, And At The Seafloor, M. J. Richardson, C. D. Hollister

Journal of Marine Research

Local resuspension of sediments along the Iceland Rise was substantiated by the collection in sediment traps of large particles whose source is clearly the seafloor. These resuspended components included benthic foraminifera, iron-oxide coated planktonic foraminifera, the glacial, subpolar assemblage planktonic foraminifera (N. pachyderma (sinistral)), and an increase in the volcanic glass and mineral grain/aggregate component with proximity to the seafloor.The horizontal flux of particulate matter in the near-bottom nepheloid layer through the region was ≃200 kg/s. The apparent vertical flux of sediment calculated from sediment traps at 500 m above bottom (mab) was an order of magnitude less than …


Observations On The Vertical Structure Of Tidal And Inertial Currents In The Central North Sea, L. R. M. Maas, J. J. M. Van Haren Jan 1987

Observations On The Vertical Structure Of Tidal And Inertial Currents In The Central North Sea, L. R. M. Maas, J. J. M. Van Haren

Journal of Marine Research

Tidal and inertial current ellipses, measured at several locations and depths in the central North Sea during a number of monthly periods in 1980, 1981 and 1982, are decomposed into counterrotating, circular components to which Ekman dynamics are applied to determine Ekman layer depths and vertical phase differences, from which are inferred overall values of the eddy viscosity and drag coefficient. Stratification effects produce an additional vertical phase shift of the anticyclonic rotary component, indicative of an inverse proportionality of the eddy viscosity to the vertical density gradient. From the time variations of the Ekman layer depths of the semidiurnal …


The Dynamics Of Near-Bed Seston Flux And Suspension-Feeding Benthos, D. K. Muschenheim Jan 1987

The Dynamics Of Near-Bed Seston Flux And Suspension-Feeding Benthos, D. K. Muschenheim

Journal of Marine Research

Benthic suspension feeders depend on the fluid medium for their supply of edible particles. The horizontal flux of organic seston is a function of the interaction of particles of varying densities with the near-bed velocity field. Analytical and numerical models of this process predict that the shape of the flux profile varies with flow rate, bottom roughness and particle settling velocity. Bulk horizontal particle flux may either decrease or increase with height above the bed. Flume experiments with natural sediments from Eastern Passage, Nova Scotia confirmed the trends predicted by the model. In a complex suspension, denser, inorganic particles have …


A Model For The Inertial Recirculation Of A Gyre, Richard J. Greatbatch Jan 1987

A Model For The Inertial Recirculation Of A Gyre, Richard J. Greatbatch

Journal of Marine Research

This paper considers the "time-mean" circulation of wind-driven ocean gyres in the limit referred to as "inertial" or "almost-free." In this limit, potential vorticity is conserved following the flow with sources and sinks of potential vorticity balancing in an integral sense around the gyre. Approximate analytic solutions are obtained for a continuously stratified quasi-geostrophic ocean by neglecting the relative vorticity in the gyre interiors. The solutions have features similar to those found in the western part of ocean basins both in eddy-resolving numerical models and in observations. In particular, a deep westward recirculation, such as proposed by Worthington (1976) for …


A Model For The Dynamics Of Nutrients And Oxygen In The Baltic Proper, Anders Stigebrandt, Fredrik Wulff Jan 1987

A Model For The Dynamics Of Nutrients And Oxygen In The Baltic Proper, Anders Stigebrandt, Fredrik Wulff

Journal of Marine Research

A horizontally integrated, time-dependent physical-biogeochemical model of high vertical resolution has been developed for the Baltic Sea proper. A seasonal pycnocline model computes the physical state of the mixed surface layer. Below this is an advective-diffusive model. The vertical advection is caused by a time-dependent, entraining bottom current which transports dense seawater into the system. The vertical distributions of volumes and sediment areas are accounted for by the use of the hypsographic function of the system. The chemical/biological processes controlling the distributions of nitrogen and oxygen are modelled as follows: Primary production is controlled by light, temperature, nutrients and density …


The Influence Of Planetary Rotation On Oceanic Double-Diffusive Fluxes, Dan Kelley Jan 1987

The Influence Of Planetary Rotation On Oceanic Double-Diffusive Fluxes, Dan Kelley

Journal of Marine Research

Does planetary rotation inhibit double-diffusive fluxes of heat and salt in oceanic thermohaline staircases? The Taylor number Ta, which measures the effect of planetary rotation on convection, is O(1) for laboratory diffusive staircases O(104) for oceanic diffusive staircases. Does this mean that laboratory-based flux laws are inapplicable in the ocean? Lacking flux measurements in double-diffusive systems, these questions are addressed using an analogy between double-diffusive convection and thermal convection. It is shown that Ta is an inappropriate parameter, and that rotating thermal fluxes collapse onto a simple curve when a new Taylor number Tano-slip …


Accurately Monitoring The Florida Current With Motionally Induced Voltages, Peter Spain, Thomas B. Sanford Jan 1987

Accurately Monitoring The Florida Current With Motionally Induced Voltages, Peter Spain, Thomas B. Sanford

Journal of Marine Research

A new experimental technique for appraising how accurately submarine-cable (subcable) voltages monitor oceanic volume transport is presented and then used to study voltages induced by the northern Florida Current. Until recently, subcable voltages have been largely dismissed as an oceanographic tool because their interpretation can be ambiguous. They depend upon the transport field, the electrical conductance of the environment, and the mutual spatial distribution of these two quantities. To examine how these three factors affect subcable voltages at a particular site, we combine data from two different velocity profilers: XCP and PEGASUS. These instruments provide vertical profiles of velocity, temperature, …


Components Of The Zooplankton Production Cycle In The Temperate Ocean, Cabell S. Davis Jan 1987

Components Of The Zooplankton Production Cycle In The Temperate Ocean, Cabell S. Davis

Journal of Marine Research

Components of the zooplankton production cycle (assimilation, respiration, and predation) on Georges Bank were analyzed using three models of increasing complexity, i.e., total biomass (Riley, 1947), size-structure (Huntley and Boyd, 1984) and species population (Davis, 1984a). Other temperate marine areas with seasonal cycles in temperature similar to Georges Bank were identified and available data on zooplankton biomass and species cycles were found. For Georges Bank, the species level model, based on well-defined empirical relationships between temperature, development rate, and fecundity, revealed that highest production occurs by small animals during warmest months (e.g., September), when biomass is low. By contrast, the …


Some Aspects Of The Oxygen-Deficient Conditions And Denitrification In The Arabian Sea, S. W. A. Naqvi Jan 1987

Some Aspects Of The Oxygen-Deficient Conditions And Denitrification In The Arabian Sea, S. W. A. Naqvi

Journal of Marine Research

Utilizing a fairly large amount of recently collected data, some outstanding questions concerning the Arabian Sea denitrification problem are addressed. The true levels of dissolved oxygen, determined colorimetrically, are about an order of magnitude lower than those reported previously from the oxygen minimum zone. Lateral advection of waters from south into the oxygen-deficient layer is suggested by the presence of an intermediate oxygen maximum discernible even at very low oxygen levels. An unusual minimum in nitrate and a corresponding maximum in nitrite are observed occasionally within the depth range 700–1,200 m at several stations, generally located in the northeastern Arabian …

On The Energetics Of The Gulf Stream At 73w, T. Rossby Jan 1987

On The Energetics Of The Gulf Stream At 73w, T. Rossby

Journal of Marine Research

From September 1980 through May 1983 a series of nineteen sections of velocity profiles were obtained across the Gulf Stream 200 km northeast of Cape Hatteras. By decomposing the velocity and temperature observations into mean and fluctuating fields in two coordinate systems, geographic (or Eulerian) and 'stream' coordinates, it is shown that at least ⅔ of the eddy kinetic and potential energy is caused by the meandering of a well defined baroclinic front with a structure that is nearly independent of space and time. It is also shown that more than 95% of the kinetic energy of the front can …


Single-Particle Dispersion, Lagrangian Structure Function And Lagrangian Energy Spectrum In Two-Dimensional Incompressible Turbulence, Armando Babiano, Claude Basdevant, Pascal Le Roy, Robert Sadourny Jan 1987

Single-Particle Dispersion, Lagrangian Structure Function And Lagrangian Energy Spectrum In Two-Dimensional Incompressible Turbulence, Armando Babiano, Claude Basdevant, Pascal Le Roy, Robert Sadourny

Journal of Marine Research

The single-particle dispersion, Lagrangian structure functions and Lagrangian energy spectra characteristic of two-dimensional incompressible turbulent flows are investigated theoretically and numerically. The domain of validity of the classical asymptotic estimates is extended; it is shown in particular that the asymptotic behavior of the single-particle dispersion at small times remains valid throughout the whole self-similar range when the Lagrangian energy spectrum is steeper than ω−1. Straightforward estimates of the Lagrangian integral time scale TL and the diffusion coefficient at large times K, based on energy and enstrophy, are proposed; to some extent, they remain valid locally, which …


A Least-Squares Fit Of The Advective-Diffusive Equations To Levitus Atlas Data, Nelson G. Hogg Jan 1987

A Least-Squares Fit Of The Advective-Diffusive Equations To Levitus Atlas Data, Nelson G. Hogg

Journal of Marine Research

The distributions of temperature, oxygen and potential vorticity on two isopycnals and the geostrophic shear between them are used to obtain the flow fields and diffusivities through a least-squares inversion of the steady state, advective-diffusive equations. The source of the data is the Levitus Atlas, and the two isopycnals are located in a 24° square centered on the Mediterranean Water tongue in the eastern North Atlantic. One isopycnal is in the thermocline and the other beneath so chosen to be near the level of maximum salinity and temperature anomaly.Although tracer distributions on the two levels are similar, the inversion suggests …


Modeling Eddy Transport Of Passive Tracers, Russ E. Davis Jan 1987

Modeling Eddy Transport Of Passive Tracers, Russ E. Davis

Journal of Marine Research

The mean advective and eddy transport of a passive scalar property is examined. Using a theory based on rational approximation of Lagrangian particle statistics, a transport equation relating the mean eddy flux and the mean concentration field Θ is developed. The transport equation is an elaborated advection-diffusion model in which the mean eddy flux is determined by the recent history of the gradient of Θ. The flux law involves an eddy diffusivity which depends on time lag and is defined in terms of fluid particle trajectories. Particle trajectories in simulated geophysical turbulence are used to test the applicability of the …


The Importance Of A Plume Of Tidally-Mixed Water To The Biological Oceanography Of The Gulf Of Maine, David W. Townsend, John P. Christensen, David K. Stevenson, Joseph J. Graham, Stanley B. Chenoweth Jan 1987

The Importance Of A Plume Of Tidally-Mixed Water To The Biological Oceanography Of The Gulf Of Maine, David W. Townsend, John P. Christensen, David K. Stevenson, Joseph J. Graham, Stanley B. Chenoweth

Journal of Marine Research

During the warmer months of the year the eastern Gulf of Maine features a plume of cold water which extends from the tidally well-mixed area adjacent to Grand Manan Island at the mouth of the Bay of Fundy southwest along the Maine coast to well beyond Penobscot Bay. Near Grand Manan Island the plume waters are cold (ca. 10°C), nearly vertically isothermal and carry high concentrations of dissolved inorganic nutrients. The analysis of temperature-salinity diagrams and hydrographic vertical section plots indicate that the deeper waters in Jordan Basin, of slope water origin, upwell and contribute a significant fraction of the …


Zooplankton Grazers As Transformers Of Ocean Optics: A Dynamic Model, Mark E. Huntley, Victor Marin, Florence Escritor Jan 1987

Zooplankton Grazers As Transformers Of Ocean Optics: A Dynamic Model, Mark E. Huntley, Victor Marin, Florence Escritor

Journal of Marine Research

A model was developed, based on data collected in the Southern California Bight region, to assess the effect of zooplankton grazing on the attenuation of light due to suspended particles. Diel vertical distribution and grazing activity of the principal zooplankton grazers in the coastal waters of southern California were studied during mid-March, 1986. Calanus pacificus exhibited vertical migration, but Acartia spp. and Paracalanus spp. did not. All species had a diel feeding rhythm, whether or not they migrated; grazing activity, measured by the gut fluorescence method, increased at night. Model parameters are temperature, particle doubling rate, particle size-frequency distribution, zooplankton …


Deep Zonal Currents In The Central Equatorial Pacific, Eric Firing Jan 1987

Deep Zonal Currents In The Central Equatorial Pacific, Eric Firing

Journal of Marine Research

A complex system of deep zonal currents in the central equatorial Pacific persisted during 16 months of current measurements spanning the 1982–1983 EI Niño episode. At least three extra equatorialcurrents appear to be permanent: the north and south intermediate countercurrents, with eastward velocity cores at 600 m depth, located 1.5–2.0° from the equator; and the south equatorial intermediate current, with a westward core at 900 m depth three or more degrees south of the equator. On the equator, the deep jets were nearly stationary during the period of these measurements. Comparison with earlier measurements shows that over longer periods the …
