A Theoretical Analysis Of The Zooplankton Population Of Georges Bank, Gordon A. Riley

Journal of Marine Research

Studi.es by Fleming (1939), Riley and Bumpus (1946), and Riley (1946) of the seasonal variations of marine phytoplankton populations have resulted in the development of a growth budget in which the rate of change of the population is balanced against the rates of all the processes that increase or decrease the organic content of the population....

Oxygen Consumption In Sea Water Over Long Periods, Norris W. Rakestraw

Journal of Marine Research

The rate and extent of oxygen consumption in sea water have been studied and measured under a variety of conditions and for a variety of purposes. Such studies, of what is often called the "biological oxygen demand," have either been involved in the estimation of the total content of organic matter or have contributed to the understanding of the processes of organic decomposition in the sea....

Note On The Correlation Of Reversing Thermometers, H. U. Sverdrup

Journal of Marine Research

Corrections have to be applied to the readings of protected and unprotected reversing thermometers because they are read at a temperature that differs from that at the time of reversal. In deriving these corrections it is generally assumed that Feruglio's (1912) equation [(5) below] is exact. It is shown here that Feruglio's equation is not quite exact, but a close approximation. From this equation practical formulae, equations (6) and (8) below, can be derived very simply without further sacrifice of accuracy.

A Momentum Integral For Surface Waves In Deep Water, Victor P. Starr

Journal of Marine Research

It has been demonstrated by the studies of Stokes (1847) and LeviCivita (1925) that surface waves of finite height which are irrotational and periodic can exist in a liquid under the influence of gravity. Furthermore, it was pointed out by Stokes that such waves produce a transport of mass in the direction of propagation and hence possess a certain horizontal momentum relative to the undisturbed water at great depths....

A Critical Wind Speed For Air-Sea Boundary Processes, Walter H. Munk

Journal of Marine Research

Most processes at the air-sea boundary are modified by the existing wind pattern. In general the rate of these processes varies gradually with wind speed. An exception seems to occur at a wind speed of about 7 m/sec; at that speed a number of apparently unrelated processes have been observed to undergo such abrupt changes that, in some instances, one is led to suspect the existance of discontinuities. Not only the rate, but the very nature of these processes seems to be altered at this critical wind speed....

Maximum And Minimum Monthly Mean Sea Surface Temperatures Charted From The "World Atlas Of Sea Surface Temperatures", Louis W. Hutchins, Margaret Scharff

Journal of Marine Research

Maximum and minimum water temperatures are of interest in oceanography in many connections. Among their more important uses, they afford the most valuable simple index of temperature conditions for analyses of the distributions of marine organisms.

Seasonal Fluctuations Of The Phytoplankton Population In New England Coastal Waters, Gordon A. Riley

Journal of Marine Research

An analysis of the seasonal phytoplankton cycle of the Georges Bank area of the Gulf of Maine (Riley, 1946) has shown that fluctuations in the population are largely controlled by the seasonal variations of a few environmental factors. An equation was developed in which the rate of change of the population in respect to time was equal to the photosynthetic rate minus the respiratory rate minus the rate of removal of the population by grazing. These rates were in turn evaluated in terms of incident solar radiation, transparency of the water, the depth of the mixed surface layer, the quantity …

Correlation Between Fluctuations In Abundance Of The Pacific Sardine (Sardinops Caerulea) And Salinity Of The Sea Water, Lionel A. Walford

Journal of Marine Research

In the course of studying several seasons' statistics on the age composition of the commercial catch of the Pacific sardine (Sardinops caerulea) I have found what appears to be a fairly indicative measure of year-class strength in the total number of three-year-old fish caught by commercial fishermen in all Pacific Coast ports of United States and Canada....

Factors Controlling Phytoplankton Populations On Georges Bank, Gordon A. Riley

Journal of Marine Research

A complex field such as oceanography tends to be subject to two opposite appr0aches. The first is the descriptive, in which several quantities are measured simultaneously and their inter-relationships derived by some sort of statistical method. The other approach is the synthetic one, in which a few reasonable although perhaps oversimplified assumptions are laid down, these serving as a basis for mathematical derivation of relationships.

A Theory Of T-S Curves As A Method For Studying The Mixing Of Water Masses In The Sea, W. B. Stockman

Journal of Marine Research

A sea or an ocean, according to Defant (1929), is composed of wat er masses which are more or less homogeneous volumes of water characterized by definite relationships of physico-chemical properties such as temperature and salinity….

A Study Of Variability In Plankton Townet Catches Of Pacific Pilchard (Sardinops Caerulea) Eggs, Ralph P. Silliman

Journal of Marine Research

During the pilchard spawning season of 1940 the United States Fish and Wildlife Service, in collaboration with the Scripps Institution of Oceanography, made periodic surveys of part of the pilchard spawning area in an attempt to make quantitative evaluations of egg deposition. In addition to estimating the number of eggs deposited in the entire survey area during the season, it was desired to make estimates of the number of eggs for parts of the area or season in connection with studies of survival, drift of larvae, etc .

Peculiarities Of Diurnal Vertical Migrations Of Zooplankton In Polar Seas, B. G. Bogorov

Journal of Marine Research

Studies of diurnal vertical migration in the polar seas are of special interest since we arc able to make observations in nature (without the possible drawbacks of laboratory experiments) of the behavior of animals under the widely varying light conditions that prevail during different seasons. Thus, during the polar summer it is possible to investigate the diurnal migration under conditions of uninterrupted daylight, during the polar autumn and spring under changing conditions of alternating days and nights, and finally in winter under conditions of permanent darkness. At present a series of special diurnal stations are available, taken mainly in the …

Phytoplankton-Zooplankton Relationships On Georges Bank, Gordon A. Riley, Dean F. Bumpus

Journal of Marine Research

Comparisons of different oceanic regions often suggest that in the largest sense there is a direct relationship between phytoplankton and zooplankton-that is, banks and coastal areas with large concentrations of phytoplankton are likely to be rich in zooplankton, while sparser crops of both occur in deep oceanic waters. On the other hand, surveys of particular areas often show an inverse relationship, with local swarms of zooplankton occurring in phytoplankton-poor waters, alternating with dense patches of phytoplankton containing few animals....

Plankton Harvesting, R. F. Shropshire

Journal of Marine Research

During the past several years proposals have been made from time to time that new sources of either bulk food material or specialized extracted products could be developed if it were possible to utilize the tremendous amounts of plankton which exist in sea water, thereby increasing the general supply and alleviating certain shortages....

Folliculinids On Oyster Shells, E. A. Andrews

Journal of Marine Research

Drifting oyster larvae often survive by fastening their shells to those of preceding generations, making shell aggregates. Many other permanently sedentary organisms also attach themselves to oyster shells; thus arise oyster shell communities, in which we may find bacteria, diatoms, red, green and brown algae, protozoans, sponges, hydroids, actinians, bryozoa, pelecypods and ascidians as fixed permanent dwellers.

A Preliminary Report On The Fouling Characteristics Of Ponce De Leon Tidal Inlet, Daytona Beach, Florida, B. R. Richards, William F. Clapp

Journal of Marine Research

In December 1941, the writers visited the exposure location of the North Florida Test Service on Ponce de Leon Inlet, near Daytona Beach, Florida, for the purpose of examining the extent of borer attack in this locality, and to determine the station's suitability for exposure tests on treated piling and for tests in the related field of marine fouling. Arrangements were effected for exposing a series of gum pine blocks throughout the year 1942 to record the progressive borer attack, and simultaneously, to record the growth of all marine fouling organisms prevalent at this location.

A Theory Of Surface Water Motion Deduced From The Wind-Induced Motion Of The Physalia, Alfred H. Woodcock

Journal of Marine Research

For many years the author has wondered why the Portuguese Manof-war (Physalia pelagica Bosc.) is so oriented physically that it is consistently driven by the wind about forty-five degrees to the left of the direction in which the wind is blowing (Figure 46, left). Records kept of this leftward tendency showed little variation in distribution or time, within the limits shown in Table I. In the literature concerning this animal no explicit reference to this question of its motion relative to the wind and water has been found.

The Vertical Stability Of The Coast At Boston In The Light Of Recent Tide Observations, H. A. Marmer

Journal of Marine Research

Since August 1921 the U. S. Coast and Geodetic Survey has had an automatic tide gauge in operation in Boston Harbor. Periodically the elevation of the tide staff, to which the observations are referred, has been checked by leveling it to a number of bench marks. These observations now cover a little over 22 years and furnish definite data for use in the study of the vertical stability of the coast.

The Photometric Determination Of Nitrate In Sea Water With A Strychnidine Reagent, B. M.G. Zwicker, R. J. Robinson

Journal of Marine Research

The routine determination of small concentrations of nitrate in water containing considerable chloride ion is limited to a few special procedures. Indirect reductive methods are usually avoided since natural waters contain other nitrogeneous substances. Direct estimations have been restricted to a few colorimetric procedures.

Studies On The Chemical Preservation Of Water Samples, Claude E. Zobell, Barbara Fay Brown

Journal of Marine Research

During the storage of water samples collected from the sea, rivers or lakes, increased bacterial activity causes changes in the organic, oxygen, carbon dioxide, ammonia, nitrate or phosphate content or the H-ion concentration of the water (Waksman and Carey, 1935 ; ZoBell and Anderson, 1936)....

Thermal And Diurnal Changes In The Vertical Distribution Of Eggs And Larvae Of The Pilchard (Sardinops Caerulea), Ralph P. Silliman

Journal of Marine Research

Knowledge of the vertical distribution of pilchard eggs and larvae is of interest from two standpoints: first, in adding to the general knowledge of the early life of this species in the sea; and second, in defining the vertical range of ite early stages so that regular surveys of the spawning grounds may be designed to sample all strata in which eggs and larvae are to be found. In reference to the second point it was desired if possible to relate vertical distribution to physical characteriEtics of the sea, so that the depth to which nets must be sent might …
