Static Stability Parameters In Oceanography, M. J. Pollak Jan 1954

Static Stability Parameters In Oceanography, M. J. Pollak

Journal of Marine Research

The use of static vertical stability criteria in oceanography is discussed and two basic types of such stability parameters are derived. It is shown how these can be determined by using sound velocity as one of the variables. Computation can be simplified by means of a graph.


Wind Mixing Currents, John C. Freeman Jr. Jan 1954

Wind Mixing Currents, John C. Freeman Jr.

Journal of Marine Research

A wind system may create an oeean current by differential mixing in a two layer ocean; such a current may be imposed on other currents due to the wind. In one situation studied, such differential mixing produced an average transport of water about 10 to 20 % of the transport due to wind stress.

Statistics Of The Sea Surface Derived From Sun Glitter, Charles Cox, Walter Munk

Journal of Marine Research

Aerial photographs of the sun's glitter on the sea surface, taken under carefully chosen conditions in the Hawaiian area, were coordinated with measurements of winds (1-27 knots) from a vessel….


Polarographic Determination Of Nitrate In Sea Water, David Tung-Whei Chow, Rex J. Robinson Jan 1953

Polarographic Determination Of Nitrate In Sea Water, David Tung-Whei Chow, Rex J. Robinson

Journal of Marine Research

A new and accurate method for the determination of nitrate in sea water, based on the pola.rographic reduction of nitrate in the presence of uranyl ions, is presented. Sulfate ions depress the reduction current by a definite proportion, depending on the chlorinity of the water sample; for chlorinities in the range of 14 to 19 ‰, this effect is rather constant. Fluoride interferes strongly with the reduction of nitrate, but aluminum or zirconyl salts may satisfactorily eliminate this effect. Other interfering ions and preservatives are also discussed. A procedure for the determination of nitrate in sea water ha.s been proposed …


On The Nature, Occurance And Origin Of Cold Low Salinity Water Along The Edge Of The Gulf Stream, W. L. Ford, J. R. Longard, R. E. Banls Jan 1953

On The Nature, Occurance And Origin Of Cold Low Salinity Water Along The Edge Of The Gulf Stream, W. L. Ford, J. R. Longard, R. E. Banls

Journal of Marine Research

In the left margin of the Gulf Stream, looking in the direction of flow, a narrow discontinuous band of relatively cold water is often found. This haa been attributed to upwelling from the colder depths of the ocean, but recent investigations throw doubt on this explanation, since this water, which forms a thin layer close to the surface, may have a lower salinity than any water in the depths. Evidence is given that the only cold low salinity source is the so-called Shelf water, which is found in a broad band between· the shore and a boundary off the Continental …


A Seawater Sampling Bottle, R. L.I. Fjarlie Jan 1953

A Seawater Sampling Bottle, R. L.I. Fjarlie

Journal of Marine Research

A new type seawater sampling bottle consisting of a tube with hinged lids and a frame holding three reversing thermometers is described. The bottle is designed to be free flushing, reliable mechanically, and simple to operate. The relative sampling efficiency of Nansen, Knudsen, Ekman and new type bottles is compared.


The Determination Of Organic Phosphorus In Sea Water With Perchloric Acid Oxidation, Andrew L. Hansen, Rex J. Robinson Jan 1953

The Determination Of Organic Phosphorus In Sea Water With Perchloric Acid Oxidation, Andrew L. Hansen, Rex J. Robinson

Journal of Marine Research

A method is proposed for the determination of organic phosphorus in sea water; in this procedure the organic material is oxidized with perchloric acid and the organic phosphorus is converted to phosphate. Oxidation in a perchloric acid medium ia superior to sulfuric acid: (a) The perchlorate salts formed upon digestion of sea water are readily water-soluble in contrast to certain sulfates; (b) A small blank correction for impurities must be applied....


A Recording Bathypitotmeter, Willem V.R. Malkus Jan 1953

A Recording Bathypitotmeter, Willem V.R. Malkus

Journal of Marine Research

The stability of a cable towed through the sea has suggested the use of its weighted end as a platform for velocity measurement. This report describes an instrument, lowered on standard hydrographic wire, which uses mechanical sensors to record speed, temperature, and pressure on a waxed paper roll. Initial measurements are presented which indicate that the vertical profile of an ocean current can be determined in approximately one hour.


The Size Of Water Masses Containing Plankton Blooms, Henry Kierstead, L. Basil Slobodkin Jan 1953

The Size Of Water Masses Containing Plankton Blooms, Henry Kierstead, L. Basil Slobodkin

Journal of Marine Research

If a phytoplankton population is assumed to be increasing logarithmically in a mass of water surrounded by water which is unsuitable for the survival of the population, it can be shown that there is a minimum critical size for the water mass below which no increase in concentration of phytoplankton can occur....


The Chaetognatha Over The Continental Shelf Of North Carolina With Attention To Their Relation To The Hydrography Of The Area, E. Lowe Pierce Jan 1953

The Chaetognatha Over The Continental Shelf Of North Carolina With Attention To Their Relation To The Hydrography Of The Area, E. Lowe Pierce

Journal of Marine Research

A series of vertical plankton samples and hydrographic data were obtained over and somewhat beyond the continental shelf off North Carolina by the ALBATROSS III during four cruises covering the period from 24 May to 14 June 1949. Continental shelf, continental slope, and Florida Current waters were found in the area sampled. Initial mixing between the water masses apparently occurs near the edge of the continental shelf....


A Possible Initial Condition For Red Tides On The Coast Of Florida, L. Basil Slobodkin Jan 1953

A Possible Initial Condition For Red Tides On The Coast Of Florida, L. Basil Slobodkin

Journal of Marine Research

It seems likely that the occurrence of a discrete mass of water, with a salinity lower than that of normal Gulf of Mexico surface water, is a necessary prerequisite for the occurrence of red tide off the Florida Coast.


Examples Of The Possible Role Of Inertia And Stratification In The Dynamics Of The Gulf Stream System, Henry Stommel Jan 1953

Examples Of The Possible Role Of Inertia And Stratification In The Dynamics Of The Gulf Stream System, Henry Stommel

Journal of Marine Research

An hypothesis is offered to explain certain major features of the Florida Current: (1) the large axial gradient of vorticity, (2) the fact that seasonal fluctuations in the Miami-Cat Key tide gauge difference are twice the amplitude of those in the Key West-Havana tide gauge difference, and (3) the fact that the Havana-Cat Key difference is at a maximum during the period of minimum flow-the opposite of what might ordinarily be expected. An elementary perturbation theory of meanders in a wide stratified current is presented and its possible application to Gulf Stream meanders is discussed....


On The Antarctic Circumpolar Current, Koji Hidaka, Mizuki Tsuchiya Jan 1953

On The Antarctic Circumpolar Current, Koji Hidaka, Mizuki Tsuchiya

Journal of Marine Research

In 1951 Munk and Palmén discussed the dynamics of the Antarctic Circumpolar Current and found that they could explain the total mass transport of this current by assuming a far larger value for the coefficient of lateral mixing than had been obtained for other parts of the oceans....

Circulation In A Meridional Plane In The Central Equatorial Pacific, Townsend Cromwell

Journal of Marine Research

Meridional sections of σt, salinity, inorganic phosphate, and dissolved oxygen, based on new data from the central equatorial Pacific, show evidences of upwelling near the equator. An Equatorial Front in the ocean surface layer is described. Sinking occurs along this front, which is found most often just north of the equator....


Microfiltration In Oceanographic Research Ii. Retention Of Colloidal Micelles By Adsorptive Filters And By Filter-Feeding Invertebrates; Proportions Of Dispersed Organic To Dispersed Inorganic Matter And To Organic Solutes, Denis L. Fox, Carl H. Oppenheimer, James S. Kittredge Jan 1953

Microfiltration In Oceanographic Research Ii. Retention Of Colloidal Micelles By Adsorptive Filters And By Filter-Feeding Invertebrates; Proportions Of Dispersed Organic To Dispersed Inorganic Matter And To Organic Solutes, Denis L. Fox, Carl H. Oppenheimer, James S. Kittredge

Journal of Marine Research

To adsorb and retain quantitatively the minute colloidal micelles held in dilute suspensions, fine inert inorganic powders (such as MgO and refined diatomaceous earth) or finely porous cellulose membranes may be employed. Minute micelles, such as molecular hemoglobin, are retained also by setous or ciliary-mucous filterfeeders....


The Surface Layer Of The Gulf Stream And Adjacent Waters, William L. Ford, A. R. Miller Jan 1953

The Surface Layer Of The Gulf Stream And Adjacent Waters, William L. Ford, A. R. Miller

Journal of Marine Research

This paper presents a description of the Gulf Stream system between Cape Hatteras and 63° W. Long. and gives a qualitative analysis of the water masses in the surface layer on the basis of observations taken from November 15 to December 6, 1948. The edge of the Stream was explored for 1,050 miles of its length. The meanderings of the Stream and its tendency to develop large eddies are demonstrated. Of special note was the 90° change in direction of the mean axis of a 150-mile segment of the Stream within a period of two weeks....


Control Of Salinity In An Estuary By A Transition, Henry Stommel, Harlow G. Farmer Jan 1953

Control Of Salinity In An Estuary By A Transition, Henry Stommel, Harlow G. Farmer

Journal of Marine Research

A theoretical reason is developed to explain why the mouth of a vertically stratified estuary should act as a constraint on the amount of salt water available for mixing in the estuary. Flume experiments designed to test this idea are described. The effect of tides on the control action and application to various estuaries is discussed.


Abundance And Growth Of Venus Mercenaria And Callocardia Moorhuana In Relation To The Character Of Bottom Sediments, David M. Pratt Jan 1953

Abundance And Growth Of Venus Mercenaria And Callocardia Moorhuana In Relation To The Character Of Bottom Sediments, David M. Pratt

Journal of Marine Research

The distribution patterns of Venus mercenaria and Callocardia morrhuana in Narragansett Bay are shown to be related to the character of the bottom. Venus is most abundant where the dominant sediments are fine, but its abundance in these sediments is strongly related to the presence of large particles such as shell and rocks as minor constituents of the substratum....


A Note On The Velocity Distribution And Bottom Stress In A Wind-Driven Water Current System, J. R.D. Francis Jan 1953

A Note On The Velocity Distribution And Bottom Stress In A Wind-Driven Water Current System, J. R.D. Francis

Journal of Marine Research

The shear stress of the wind on a water surface is sometimes found by measuring the slope of the surface in a lake or wind tunnel. The stress on the bottom of the lake due to the return water current is an error term which has been variously estimated. An experimental method of determining the error is described, and the results indicate that it is but some 1½% of the wind stress.


Interference Phenomena In The Tides Of The Woods Hole Region, Alfred C. Redfield Jan 1953

Interference Phenomena In The Tides Of The Woods Hole Region, Alfred C. Redfield

Journal of Marine Research

The relations of mean range of tide, time of high water, and time of slack water along Vineyard and Nantucket Sounds may be attributed to the interference of tidal waves entering the sounds from their opposite ends. Interference of the semidiurnal constituents is maximal in the neighborhood of Woods Hole where the great reduction of these constituents, relative to the diurnal constituents, results in a pronounced diurnal inequality in the range of successive tides at appropriate phases of the moon....


Correlation Of Currents With The Distribution Of Adult Daphnia In Lake Mendota, Robert A. Ragotzkie, R. A. Bryson Jan 1953

Correlation Of Currents With The Distribution Of Adult Daphnia In Lake Mendota, Robert A. Ragotzkie, R. A. Bryson

Journal of Marine Research

Simultaneous observations of current pattern and distribution of Daphnia pulex indicate that in Lake Mendota this zooplankter is concentrated by wind-induced convergence. Theoretical examination of this hypothesis yields results which compare favorably with observations.


A Bathymetric Profile Across The Hudson Submarine Canyon And Its Tributaries, John Northrop Jan 1953

A Bathymetric Profile Across The Hudson Submarine Canyon And Its Tributaries, John Northrop

Journal of Marine Research

Echo soundings recorded continuously during a crossing of the Hudson Submarine Canyon system 200 miles southeast of New York Harbor show that the tributaries in 1200-1800 fathoms depth differ in profile and gradient from the Hudson Canyon proper….


On The Statistical Distribution Of The Heights Of Sea Waves, M. S. Longuet-Higgins Jan 1953

On The Statistical Distribution Of The Heights Of Sea Waves, M. S. Longuet-Higgins

Journal of Marine Research

The statistical distribution of wave-heights is derived theoretically on the assumptions (a) that the wave spectrum contains a single narrow band of frequencies, and (b) that the wave energy is being received from a large number of different sources whose phases are random. Theoretical relations are found between the root-meansquare wave-height, the mean height of the highest one-third (or highest one-tenth) waves and the most probable height of the largest wave in a given interval of time. There is close agreement with observation.


A Theory Of Fog Formation, Robert G. Fleagle Jan 1953

A Theory Of Fog Formation, Robert G. Fleagle

Journal of Marine Research

It is shown that just above a cold black-body surface the effect of radiation is to warm the air, whereas just above a warm surface the effect of radiation is to cool the air. Above a height of the order of one meter the signs of the radiative temperature change are reversed. Since, as Emmons and Montgomery (1947) have pointed out, fog formation usually requires net radiation from the air, it follows that, above a cold surface, fog forms only above a certain critical height whereas above a warm surface fog forms below a critical height. Other processes which produce …


Circulation In The Upper Mixed Layer Of The Equatorial North Pacific, Kozo Yoshida, Han-Lee Mao, Paul L. Horrer Jan 1953

Circulation In The Upper Mixed Layer Of The Equatorial North Pacific, Kozo Yoshida, Han-Lee Mao, Paul L. Horrer

Journal of Marine Research

The circulation in the upper mixed layer in the equatorial region of the North Pacific is treated by solving the steady-state equations containing terms of Corioli's force, pressure gradient, and horizontal as well as vertical mixing….


Parameters Of Turbulence In The Sea, Gordon A. Riley Jan 1952

Parameters Of Turbulence In The Sea, Gordon A. Riley

Journal of Marine Research

Dimensional analysis, combined with statistical examination of data, leads to the development of an equation for eddy diffusivity that is expressed in terms of readily measurable physical parameters----mean current speed, the distance between points of observation, the density of the water, and the dynamic molecular viscosity.....


Midsummer Renewal Of Oxygen Within The Hypolimnion, R. A. Bryson, V. E. Suomi Jan 1952

Midsummer Renewal Of Oxygen Within The Hypolimnion, R. A. Bryson, V. E. Suomi

Journal of Marine Research

Following a very rainy period in the summer of 1950, oxygen temporarily reappeared in the hypolimnion of Lake Mendota. It is postulated that the oxygen was introduced there by density currents of cold, silt laden, well oxygenated runoff water.


The Growth And Viability Of Sixty-Three Species Of Marine Bacteria As Influenced By Hydrostatic Pressure, Carl H. Oppenheimer, Claude E. Zobell Jan 1952

The Growth And Viability Of Sixty-Three Species Of Marine Bacteria As Influenced By Hydrostatic Pressure, Carl H. Oppenheimer, Claude E. Zobell

Journal of Marine Research

The hydrostatic pressure of sea water, which increases approximately 0.1 atmosphere per meter of depth, was found to affect the viability, reproduction, and morphology of 63 stock cultures of marine bacteria representing several genera. Many of the cultures were killed at 27° C by pressures ranging from 200 to 600 atm, although some few reproduced at 600 atm. Initial inoculum concentrations of the various bacteria appeared to influence their ability to reproduce or to tolerate high pressures. Pressures exceeding 400 atm inhibited the fission of certain bacteria without stopping their growth, thereby resulting in bizarre cells, some of which formed …
