The Field Use Of A Salinity-Temperature-Depth Recorder, William L. Ford Jan 1949

The Field Use Of A Salinity-Temperature-Depth Recorder, William L. Ford

Journal of Marine Research

A salinity-temperature-depth recorder that provides a continuous record of the salinity and temperature of sea water has been described by Jacobson. The present paper is a discussion of the use of this instrument in the field and of its application to a variety of hydrographic problems.


The Determination Of Nitrates In Sea Water, Rex J. Robinson, Thomas G. Thompson Jan 1948

The Determination Of Nitrates In Sea Water, Rex J. Robinson, Thomas G. Thompson

Journal of Marine Research

The concentrations of nitrite-nitrogen in sea water varies from 0.000 to 2.00 microgram atoms (µg. atoms) per liter of sea water at 20° C. In the open ocean nitrites are seldom found in depths below 100 meters, and even at these depths the water may be completely devoid of nitrites. When occurring in waters near the surface, the concentration is generally less than 0.10 µg. atom of nitrite-nitrogen per liter. The higher values are obtained at times in the waters on the continental shelf and in sounds, straits, fjords and estuaries.


Note Concerning Human Respiratory Irritation Associated With High Concentrations Of Plankton And Mass Mortality Of Marine Organisms, Alfred H. Woodcock Jan 1948

Note Concerning Human Respiratory Irritation Associated With High Concentrations Of Plankton And Mass Mortality Of Marine Organisms, Alfred H. Woodcock

Journal of Marine Research

There is increasing evidence that high concentrations of plankton are sometimes associated with mass mortality among marine animals (Taylor, 1917, see ref's pp. 14-16; Marchand, 1928; BrongersmaSanders, 1947; Gunter, et al., 1947).


The Measurement Of The Viscosity Coefficient Of Sea Water, Yasuo Miyake, Masami Koizumi Jan 1948

The Measurement Of The Viscosity Coefficient Of Sea Water, Yasuo Miyake, Masami Koizumi

Journal of Marine Research

In an old study by Ruppin and Krummel (Krümmel, 1907: 281), the viscosity of sea water was measured by the method of Wil. Ostwald. However, at that time the data for the viscosity of sea water were given relative to that of pure water at 0° C. Since then several precise measurements (Dorsey, 1940: 182) have been made and reliable data obtained, and therefore it is necessary to determine more exact values for the viscosity of sea water.


Progress In The Statistical Theory Of Turbulance, Theodore Von Kármán Jan 1948

Progress In The Statistical Theory Of Turbulance, Theodore Von Kármán

Journal of Marine Research

The fundamental notion of statistical mean values in fluid mechanics was first introduced by Reynolds (1894). In his description of the turbulent motion he started from the molecular disorder. By considering the mean value and correlations in the molecular motion, as it was shown before, one obtains the equation of Stokes-Navier (1845, 1822).


The Effect Of Ocean Current On Internal Waves, Bernhard Haurwitz Jan 1948

The Effect Of Ocean Current On Internal Waves, Bernhard Haurwitz

Journal of Marine Research

In a fluid whose density changes with the height, either abruptly at a sharp surface of discontinuity or gradually, it is possible to have internal wave motions whose amplitude is greatest at the density discontinuity or, in the case of a gradual density change, somewhere in the interior of the fluid and not at the free upper surface where the surface waves have their maximum amplitude....


Some Empirical Relations Between Seasonal Values Of (E–P) And Surface Salinities Over The North Atlantic, Woodrow C. Jacobs Jan 1948

Some Empirical Relations Between Seasonal Values Of (E–P) And Surface Salinities Over The North Atlantic, Woodrow C. Jacobs

Journal of Marine Research

In the absence of horizontal flow, the surface salinity of any part of the ocean is mainly determined by three processes: Decrease of salinity by precipitation P, increase of salinity by evaporation E, and change of salinity by vertical mixing


The Sea Sampler, Athelstan F. Spilhaus, Arthur R. Miller Jan 1948

The Sea Sampler, Athelstan F. Spilhaus, Arthur R. Miller

Journal of Marine Research

The original sea sampler, as described by Spilhaus (1940), consisted of six bottles, each built somewhat like a small version of a standard Nansen bottle. These surrounded a cylinder containing a releasing block which was operated by an ordinary bathythermograph pressure element. The tripping block, which was moved by the pressure element, was scored and grooved to accommodate a series of triggers, one for each bottle, which closed the stop-cocks in turn as the whole instrument reached predetermined pressures....


Underwater Ambient Noise, R. S. Alford, J. W. Emling Jan 1948

Underwater Ambient Noise, R. S. Alford, J. W. Emling

Journal of Marine Research

Underwater sound continues to be a problem of high priority in naval warfare. Since atomic bombing may render obsolete most types of surface ships, the relative if not absolute importance of the submarine certainly has increased. Thus, the U. S. Navy logistics chief recently told a congressional committee, "By far the most important and difficult problem which confronts the navy in so far as ship characteristics and fleet operating technique are concemed is the problem of undersea warfare."


A Biochemical Study Of The Marine Annelid Worm, Thoracophelia Mucronata: Its Food, Biochromes And Carotenoid Metabolism, Denis L. Fox, Sheldon C. Crane, Bayard H. Mcconnaughey Jan 1948

A Biochemical Study Of The Marine Annelid Worm, Thoracophelia Mucronata: Its Food, Biochromes And Carotenoid Metabolism, Denis L. Fox, Sheldon C. Crane, Bayard H. Mcconnaughey

Journal of Marine Research

Comparative biochemical studies of numerous marine invertebrates and fishes have indicated that the majority of such species so far examined selectively assimilate and store xanthophyllic or allied oxygenated carotenoids rather than carotenes, when consuming food containing both types of pigment. In some forms there is complete exclusion of carotenes, e.g., in several fishes, in the sea mussel (Mytilus californianus), in at least three brittle stars, and in some color-variants of the anemone Metridium senile. Some asteroid echinoderms store carotenes, but in far lower concentrations than xanthophylls, while four species of echinoids appear to assimilate relatively greater quantities of carotenes (Fox, …


New Genera And Species Of Batoid Fishes, Henry B. Bigelow, William C. Schroeder Jan 1948

New Genera And Species Of Batoid Fishes, Henry B. Bigelow, William C. Schroeder

Journal of Marine Research

The trawling campaigns carried out by the research vessel ATLANTIS of the Woods Hole Oceanographic Institution along the north and south coasts of Cuba during the winter of 1938 and spring of 1939, under the joint auspices of the University of Havana and of Harvard University, brought to light along the 200-500 fathom zone an abundant population of small skates (Family Rajidae), the existence of which had not previously been suspected there....


Estimations Of Abundance Of The Eggs Of The Pacific Pilchard (Sardinops Caerulea) Off Southern California During 1940 And 1941, Oscar E. Sette, Elbert H. Ahlstrom Jan 1948

Estimations Of Abundance Of The Eggs Of The Pacific Pilchard (Sardinops Caerulea) Off Southern California During 1940 And 1941, Oscar E. Sette, Elbert H. Ahlstrom

Journal of Marine Research

One of the more important items of information required for an understanding of the dynamics of population numbers in marine fish stocks is the rate of replenishment of the stock through its reproductive process. It has been established for the Pacific pilchard, or California sardine (Sardinops caerulea), that some spawning seasons give rise to much larger year-classes than others (Clark, 1939), as measured at the time the year-class reaches commercial age....


Radioactivity Of Ocean Sediments Vii. Rate Of Deposition Of Deep-Sea Sediments, Wm. D. Urry Jan 1948

Radioactivity Of Ocean Sediments Vii. Rate Of Deposition Of Deep-Sea Sediments, Wm. D. Urry

Journal of Marine Research

Many of the problems of past geological history and of present processes of sedimentation require a knowledge of the rate of accumulation of marine sediments. A very important step in the determination of the rate of deposition of a sediment is the measurement of a time interval. This is equally true whether use be made of the stratigraphic method with core samples or the supply method based upon the rate of supply of sedimentary material to the sea. The stratigraphic method gives rates for individual localities, whereas the supply method yields averages for large areas over long periods of geological …


Radium Analyses Of Marine Sediments In Northern Pacific And Adjacent Waters, C. L. Utterback, L. A. Sanderman Jan 1948

Radium Analyses Of Marine Sediments In Northern Pacific And Adjacent Waters, C. L. Utterback, L. A. Sanderman

Journal of Marine Research

Although systematic soundings of the ocean bottom were initiated approximately 100 years ago, and although the United States Coast and Geodetic Survey took hundreds of ocean bottom samples beginning about 75 years ago, it was not until the ship CARNEGIE collected a number of bottom samples at great depths that information began to be available on the radioactive properties of deep ocean sediments....

The Determination Of Phosphates In Sea Water, Rex J. Robinson, Thomas G. Thompson Jan 1948

The Determination Of Phosphates In Sea Water, Rex J. Robinson, Thomas G. Thompson

Journal of Marine Research

The concentration of phosphates in sea water varies from 0.000 to about 2.00 microgram atoms (µg. atoms) phosphate-phosphorus per liter at 20° C. Occasionally a maximum of 3.00 µg. atoms may be found in some deep arms of the sea.


The Determination Of Silicate In Sea Water, Rex J. Robinson, Thomas G. Thompson Jan 1948

The Determination Of Silicate In Sea Water, Rex J. Robinson, Thomas G. Thompson

Journal of Marine Research

The normal range of silicate in sea water is from 0.0 to about 200 µg. atoms Si per liter at 20° C. It has not been fully demonstrated whether the silicate determined by the method described below is in the colloidal or ionic form or both.


Quantitative Studies Of Summer Plankton Populations Of The Western North Atlantic, Gordon A. Riley, Samy Gorgy Jan 1948

Quantitative Studies Of Summer Plankton Populations Of The Western North Atlantic, Gordon A. Riley, Samy Gorgy

Journal of Marine Research

The following is an account of plankton measurements obtained during a cruise2 of the research vessel "Atlantis" to the Mid-Atlantic Ridge between July and September 1947. It is primarily a study of plankton in the great central Atlantic eddy known as the Sargasso Sea. For comparative purposes, a small amount of material was obtained from New England coastal waters, the so-called slope water area lying off the edge of the Continental Shelf, and the Gulf Stream. An August cruise by the "Balanus" assisted in gathering this subsidiary data. The material to be described consists of phytoplankton assays by the plant …


Harald Ulrik Sverdrup - An Appreciation, Oger Revelle, Walter Munk Jan 1948

Harald Ulrik Sverdrup - An Appreciation, Oger Revelle, Walter Munk

Journal of Marine Research

As a young man Harald Sverdrup spent seven years on Amundsen's MAUD expedition in the icy wastes of the Arctic Sea. The observations he collected during this period form the basis of fifty published papers and constitute much of our factual knowledge about geophysical phenomena in the Arctic. Nevertheless, those years of voluntary exile would be of relatively small interest to his colleagues were it not for their effect on his personal and scientific qualities, and the insight which they give into his character.


Evidence Of World-Wide Submergence, Francis P. Shepard Jan 1948

Evidence Of World-Wide Submergence, Francis P. Shepard

Journal of Marine Research

At the beginning of the century geologists were discussing the idea that the glacial period was the result of enormous vertical movements of the continents. Uplifts were said to have cooled the climates, bringing on glaciation, and subsequent subm~rgence caused the glaciers to melt. This hypothesis was supported by the finding of deep canyons on the sea floor which indicated the former elevated condition of the continents....


The Exchange Of Oxygen Across The Sea Surface, Alfred C. Redfield Jan 1948

The Exchange Of Oxygen Across The Sea Surface, Alfred C. Redfield

Journal of Marine Research

In temperate latitudes the oxygen content of sea water near the surface varies with the season. This results because the solubility of oxygen in the water changes with its temperature and because of the unequal production and utilization of oxygen by organisms at different seasons. Both factors cause an exchange of oxygen across the sea's surface. The present paper is an attempt to determine the magnitude of this exchange as it occurs in the Gulf of Maine and to evaluate the factors responsible.


Changes In The Fish Fauna Of Western North America Correlated With Changes In Ocean Temperature, Carl L. Hubbs Jan 1948

Changes In The Fish Fauna Of Western North America Correlated With Changes In Ocean Temperature, Carl L. Hubbs

Journal of Marine Research

Many lines of evidence support the conclusion that temperature is a factor of prime importance in the distribution of marine fishes along the Pacific Coast of North America. The correlation between water temperature and the type of fish found is so definite that I feGl justified in drawing inferences, from the known data of fish distribution, regarding ocean temperatures of the past and regarding the temperatures of regions for which the physical data are inadequate....


Methods For Estimating Dynamic Slopes And Currents In Shallow Waters, Pier Groen Jan 1948

Methods For Estimating Dynamic Slopes And Currents In Shallow Waters, Pier Groen

Journal of Marine Research

In computing relative currents in the sea from the mass distribution, a well known difficulty is encountered when a section extends into relatively shallow water; then a mass of land becomes part of the section.

1. The convenience of the bathythermograph for making rapid detailed surveys of the thermal structure in vertical sections of the ocean is leading to an accumulation of data on ocean temperatures far exceeding that on the corresponding salinities….


Notes On The Distribution Of Energy Frequency In Surface Waves, C. G. Rossby Jan 1947

Notes On The Distribution Of Energy Frequency In Surface Waves, C. G. Rossby

Journal of Marine Research

The behavior of irrotational surface waves of small amplitude in deep water has been thoroughly investigated through theoretical studies extending over a period of more than one hundred years. Waves of this type are therefore particularly well suited for demonstration of the characteristics of energy and frequency distribution and propagation in dispersive media. In the present note a few comments will be made on the distribution of energy with respect to frequency in such waves.


Environmental Characteristics Of A River Estuary, Carroll Blue Nash Jan 1947

Environmental Characteristics Of A River Estuary, Carroll Blue Nash

Journal of Marine Research

The Patuxent River is one of the larger tributaries of the Chesapeak~ Bay. It has its origin in the north-central part of Maryland at an. altitude of about 800 feet and empties into the. western side of the bay at a point about halfway between the mouth and upper limits of the bay. Its basin is a hilly, rolling country without lakes and is characterized by low shores that rise gently toward the interior. The soil consists of sand and clay and contains some limestone in local areas. The drainage area of the river is about 960 square miles, and …


Measurements Of Production In Fertilized Salt-Water, W. T. Edmondson, Yvette H. Edmondson Jan 1947

Measurements Of Production In Fertilized Salt-Water, W. T. Edmondson, Yvette H. Edmondson

Journal of Marine Research

The present paper describes some results of several exploratory experiments made at the Woods Hole Oceanographic Institution in connection with a proposed study of organic production in salt waters. An attempt is made to relate the viewpoint of the present paper to the more outstanding aims of fertilization work. Aside from practical matters of aquiculture, addition of nutrients to water is a valuable tool for studying what has been called food-chain dynamics. Briefly stated, the object of the described experiments was to determine immediate effects of fertilization upon the vital activities of the phytoplankton.
