Daily Patterns Of Fluorescence In Vivo In The Central Equatorial Pacific, Patrick J. Setser, Norman L. Guinasso Jr., David R. Schink Jan 1982

Daily Patterns Of Fluorescence In Vivo In The Central Equatorial Pacific, Patrick J. Setser, Norman L. Guinasso Jr., David R. Schink

Journal of Marine Research

A daily cycle of fluorescence in vivo was strikingly apparent in surface waters of the central equatorial Pacific between latitudes 4N and 10S, but not in waters to the north or south of this zone. These changes in fluorescence did not represent changes in chlorophyll-a concentration, but rather a photoinhibition of fluorescence by ambient light. Higher nutrient and chlorophyll-a concentrations were found in the region where cycling occurred....

On The Interaction Between Surface Waves And Undulations On The Seabed, A. G. Davies Jan 1982

On The Interaction Between Surface Waves And Undulations On The Seabed, A. G. Davies

Journal of Marine Research

When surface water waves propagate over undulating seabed topography, the resulting interaction creates a near-bed velocity field which has important implications for sediment transport. Linear perturbation theory is used here to examine this interaction for the case of two-dimensional oscillatory uniplanar nonseparating flow, in which the surface wave crests are parallel to the crests of the bottom undulations....


Spacial Distributions Of Major Phytoplankton Community Components In Narragansett Bay At The Peak Of The Winter-Spring Bloom, Franklin H. Farmer, Gabriel A. Vargo, Clarence A. Brown Jr., Olin Jarrett Jr. Jan 1982

Spacial Distributions Of Major Phytoplankton Community Components In Narragansett Bay At The Peak Of The Winter-Spring Bloom, Franklin H. Farmer, Gabriel A. Vargo, Clarence A. Brown Jr., Olin Jarrett Jr.

Journal of Marine Research

The horizontal distribution of phytoplankton in western Narragansett Bay at the height of the 1978 winter-spring bloom was characterized using data from an airborne fluorosensor to extend in situ point measurements of chlorophyll a and phytoplankton population composition to linear or area coverage....


Effect Of Pressure On The Partial Equivalent Volume Of Salts In Seawater, Alvin Bradshaw, Karl E. Schleicher Jan 1982

Effect Of Pressure On The Partial Equivalent Volume Of Salts In Seawater, Alvin Bradshaw, Karl E. Schleicher

Journal of Marine Research

The effect of pressure on the partial equivalent volumes of salts of the major ions in 35%, seawater at 10 and 25°C was determined for applied pressures of 400 and 1000 bars from measurements of the change in solution compression with salt concentration....


A Theory Of The Wind-Driven Circulation Ii. Gyres With Western Boundary Layers, William R. Young, Peter B. Rhines Jan 1982

A Theory Of The Wind-Driven Circulation Ii. Gyres With Western Boundary Layers, William R. Young, Peter B. Rhines

Journal of Marine Research

The quasigeostrophic, wind-driven circulation theory given by Rhines and Young (1982b) is extended in two directions. First, we consider forcing patterns which are not contrived so as to close without a western boundary layer. The resulting barotropic circulation pattern (see Fig. 1) has the well known east-west asymmetry produced by the β-effect....


Input Of Tritium To Intermediate Depth Water In The South Pacific, J. R. Harries, G. E. Calf Jan 1982

Input Of Tritium To Intermediate Depth Water In The South Pacific, J. R. Harries, G. E. Calf

Journal of Marine Research

Tritium concentrations have been determined for seawater samples collected near the western boundary of the South Pacific. The deepest penetration of tritium, in terms of either depth or isopycnal surface, occurs between latitudes 14 and 30S and the penetration is greater than that observed in the mid-South Pacific during the Geochemical Ocean Sections Study (GEOSECS) cruise....


The Flow Of Equatorial Kelvin Waves And The Equatorial Undercurrent Around Islands, P. B. Rowlands Jan 1982

The Flow Of Equatorial Kelvin Waves And The Equatorial Undercurrent Around Islands, P. B. Rowlands

Journal of Marine Research

A linear theory is presented for the flow of equatorial Kelvin waves and of the equatorial undercurrent around islands situated on or near the equator. The island is modelled as an infinitesimally thin meridional barrier. It is shown that small islands affect the flow very little, while large islands effectively block the flow....


Large-Scale Interannual Physical And Biological Interaction In The California Current, Dudley B. Chelton, Patricio A. Bernal, John A. Mcgowan Jan 1982

Large-Scale Interannual Physical And Biological Interaction In The California Current, Dudley B. Chelton, Patricio A. Bernal, John A. Mcgowan

Journal of Marine Research

Thirty years of temperature, salinity, steric height and zooplankton data are examined to explore the potential causes of large-scale biological variability in the California Current. The physical and biological properties are all found to be dominated by a pronounced interannual signal with very large spatial scale....

Weddell Deep Water Variability, Arnold L. Gordon Jan 1982

Weddell Deep Water Variability, Arnold L. Gordon

Journal of Marine Research

Temperature of the Weddell Deep Water west of the Greenwich Meridian in 1977 is dramatically lower than that observed in the same region in 1973. The most intense thermal alteration extends from approximately 200 m to 2700 m. Cooling, which averages 0.2°C, accompanies a nearly density compensating salinity decrease, averaging 0.02‰....


On The Determination Of Absolute Velocities In The Ocean, Manuel E. Fiadeiro, George Veronis Jan 1982

On The Determination Of Absolute Velocities In The Ocean, Manuel E. Fiadeiro, George Veronis

Journal of Marine Research

An empirical search procedure based only on hydrographic data and the use of the dynamical method provides a good estimate of the level of no motion. The criterion is to select the level that yields the minimum mean square transport imbalances for the set of carefully chosen independent layers....


Observations Of Near-Equatorial Flows In The Eastern Pacific, Ants Leetmaa Jan 1982

Observations Of Near-Equatorial Flows In The Eastern Pacific, Ants Leetmaa

Journal of Marine Research

Direct measurements were made in 1980 and 1981 of the near-equatorial flow field along sections at 110, 102.5, 95, and 85W. The Equatorial Undercurrent weakens as it approaches the Galapagos. Most of the transport is lost from the warmer, upper part of the current....


The Seasonal Hydrography And Circulation Over Nantucket Shoals, Richard Limeburner, Robert C. Beardsley Jan 1982

The Seasonal Hydrography And Circulation Over Nantucket Shoals, Richard Limeburner, Robert C. Beardsley

Journal of Marine Research

Bimonthly hydrographic surveys were begun in May, 1978 to measure the spatial structure and temporal variability of the temperature and salinity fields about Nantucket Shoals over one annual cycle. Moored current meters were also deployed in January, 1979 and in July, 1979 to directly measure the current field and examine low-frequency current variability over the shoals....


Recirculation Reconsidered, James Luyten, Henry Stommel Jan 1982

Recirculation Reconsidered, James Luyten, Henry Stommel

Journal of Marine Research

The Atlantis 50W IGY section is used to test ideas about the application of inverse methods to the determination of the absolute geostrophic circulation of the North Atlantic. We argue that the uncertainties in determining the imbalances of relative layer-transports in the deep layers are so great that the heavy weight given them in the Wunsch-Grant (1982) charts of absolute circulation yields results that are artificially dominated by qottom topography and are not realistic....


Circulation In The Eastern North Atlantic, Peter M. Saunders Jan 1982

Circulation In The Eastern North Atlantic, Peter M. Saunders

Journal of Marine Research

Basin-wide geostrophic shear profiles have been computed for several latitudes in the eastern Atlantic between 32 and 53N. The absolute velocity on each section has been chosen so that the transport satisfies the Sverdrup relation. It is concluded that the wind-driven currents are not confined to the upper thermocline but extend to great depth....


Low-Frequency Temperature Fluctuations Between Ocean Station Echo And Bermuda, W. Sturges, Alan Summy Jan 1982

Low-Frequency Temperature Fluctuations Between Ocean Station Echo And Bermuda, W. Sturges, Alan Summy

Journal of Marine Research

Hydrographic data at Ocean Station Echo (35N, 48W) form an almost continuous 6-year series ending in 1973. The temperature fluctu ations at periods longer than about 8 months appear to be largely from the first vertical mode, and at periods of about 7 to 4 months from the second. These fluctuations are found to be coherent with those seen in the Panulirus data, at Bermuda, if the travel time for group velocity is included....

On The Currents And Water Masses North Of The Antilles/Bahamas Arc, John T. Gunn, D. Randolph Watts Jan 1982

On The Currents And Water Masses North Of The Antilles/Bahamas Arc, John T. Gunn, D. Randolph Watts

Journal of Marine Research

The Antilles Current, which is supposed to flow from the Atlantic North Equatorial Current along the Antilles and Bahamas island arc and contribute to the Gulf Stream, does not always exist. Data from the two most extensive grids of hydrographic surveys yet available in this region, one in summer and one in winter, show that mesoscale eddies dominate the baroclinic current field and the distribution of water properties....

The Vertical Flux Of Particulate Organic Nitrogen In The Sea: Decomposition Of Amino Acids In The Peru Upwelling Area And The Equatorial Atlantic, Cindy Lee, Carolyn Cronin Jan 1982

The Vertical Flux Of Particulate Organic Nitrogen In The Sea: Decomposition Of Amino Acids In The Peru Upwelling Area And The Equatorial Atlantic, Cindy Lee, Carolyn Cronin

Journal of Marine Research

Marine particulate matter samples were collected in moored and free-drifting sediment traps deployed off the coast of Peru during February, 1978. Three types of amino acids were analyzed in these samples: free extractable amino acids (FEA), hydrolyzed extractable amino acids (HEA) and total hydrolyzed amino acids (fHA). FEA and HEA were also analyzed in moored trap samples from the PARFLUX E station in the equatorial Atlantic Ocean....


Modeling Salt-Fingering Structures, Otto Zeman, John L. Lumley Jan 1982

Modeling Salt-Fingering Structures, Otto Zeman, John L. Lumley

Journal of Marine Research

Results are presented of calculations with a second-order turbulence model which has been modified to evolve continuously from full turbulent convection to thermo-haline convection, under appropriate circumstances. A three-layer system is simulated, with a salt-fingering interface between two convectively-driven turbulent layers. Experimental results on the salt/heat flux ratio are reproduced.

The Worthington Effect And The Origin Of The Younger Dryas, W. H. Berger, J. S. Killingley Jan 1982

The Worthington Effect And The Origin Of The Younger Dryas, W. H. Berger, J. S. Killingley

Journal of Marine Research

An increase in CO2 content of the atmosphere during deglaciation is explained by buildup of shelf carbonate with concomitant release of "excess CO2" to the surrounding upper ocean, from whence some of it enters the atmosphere. Mixing with deep water removes excess CO2 to the abyss where it is used up in dissolving foraminifera and coccoliths....
