The Significance Of The Mississippi River Drainage For Biological Conditions In The Northern Gulf Of Mexico, Gordon A. Riley Jan 1937

The Significance Of The Mississippi River Drainage For Biological Conditions In The Northern Gulf Of Mexico, Gordon A. Riley

Journal of Marine Research

Plankton collections and bottom hauls made during the 1935 expedition of the "Atlantis" to the Gulf of Mexico suggested that there is a zone of high productivity in the shallow water area near the mouth of the Mississippi, and since the effect of river outflow on ocean life is a phase of marine biology which has not yet received adequate attention, further investigation seemed desirable.

Note On The Flow Of Streams In A Rotating System, Athelstan F. Spilhaus Jan 1937

Note On The Flow Of Streams In A Rotating System, Athelstan F. Spilhaus

Journal of Marine Research

Certain similarity of' the observed fl ow in the ocean and in the atmospherr to the behavior of' a wake stream, for which a complete, experimentally verified theory is available (1), led Rossby (2) to initiate the extension of the wake stream idea first to a rotating system and secondly, to a stratified medium. Several interesting predictions were made by Rossby as a result of his theoretica l investigation; and it was the purpose of the experiments carried out by the autho1, to in vestigate to what extent these predictions could be verified in the laboratory. The experiments were of …

Seasonal Variations In The Surface Waters Of San Juan Channel During The Five Year Period, January 1931 To December 30, 1935, Lyman D. Phifer, Thomas G. Thompson Jan 1937

Seasonal Variations In The Surface Waters Of San Juan Channel During The Five Year Period, January 1931 To December 30, 1935, Lyman D. Phifer, Thomas G. Thompson

Journal of Marine Research

Although there is a mass of data available on the physical and chemical properties of sea water in various part., of the world, relatively little data may be had from localities where continuous long time observations have been made. At the Oceanographic Laboratories on San Juan Channel near Friday Harbor, Wash., the water body is unique in that it is rather homogeneous for a depth of 100 meters. We propose to demonstrate the yearly and seasonal variations and fluctuations of the physical and chemical properties, and the phytoplankton calendar of this water mass and to determine if long time periodicities …

The Sex-Ratio In Alternational Hermaphrodites, With Especial Reference To The Determination Of Rate Of Reversal Of Sexual Phase In Oviparous Oysters, Martin D. Burkenroad Jan 1937

The Sex-Ratio In Alternational Hermaphrodites, With Especial Reference To The Determination Of Rate Of Reversal Of Sexual Phase In Oviparous Oysters, Martin D. Burkenroad

Journal of Marine Research

In a population in which the sexual nature of the individuals is not subject to change, the sex-ratio of a given brood as determinable in practice may be different at different times if there is a differential rate of maturation for the two sexes, or a differential death rate. Excluding from present consideration the periods in the life of the population at whi ch these differentials may operate, however, the sex-ratio of the brood at any given time shou ld be identical with that at any other time....

Preface, A. E. Parr Jan 1937

Preface, A. E. Parr

Journal of Marine Research

The Journal of Marine Research is intended particularly as an outlet for shorter articles on any aspect of scientific marine investigations or ·any subject with a direct or indirect bearing upon the problems of the sea. Due to the intimate connection and mutual relationship between hydrospheric and atmospheric events in nature, and to the virtual identity of dynamic methods and principles in Meteorology and Oceanography, contributions to physical meteorological theory in general and to our knowledge about the relationship between ocean and air, in particular will be considered equally pertinent to marine as to meteorological research, and therefore within the …

On The Mutual Adjustment Of Pressure And Velocity Distributions In Certain Simple Current Systems, C. G. Rossby Jan 1937

On The Mutual Adjustment Of Pressure And Velocity Distributions In Certain Simple Current Systems, C. G. Rossby

Journal of Marine Research

The writer (J) recently advanced the hypothesis that the horizontal pressure gradients observed in the current systems of the atmosphere and the ocean to a large extent must be interpreted as reactions to the Coriolis' forces impressed upon these systems by the rotation of the earth. Observational support for this point of view was found in the fact that both the temperature-salinity and oxygen-salinity correlation curves obtained from stations on both sides of the Gulf Stream in the region between Nova Scotia and Bermuda are very nearly identical, even though the individual isotherms may drop as much as 700 meters …
