Biological Results of The Snellius Expedition: XVI. The Pisces and Leptocardi…
This paper deals with the material of the Fishes collected during the cruise of the “Snellius”. As the biological work during the expedition was not the chief scope, one could expect that the collection of Fishes would not be so extensive as from other expeditions. A great deal of the collecting of material during the cruise was done by plankton nets, which gives the results that most of th…

An Analysis of The Stirring and Mixing Processes in Incompressible Fluids
In the laboratory, the phenomena accompanying the mixture of two fluids are so commonplace that they do not seem to merit investigation. In the ocean and atmosphere, the phenomena are presumably very similar, but the lack of a good theory on which to base calculations complicates the problem much more than in the laboratory.

A Study on The Foaming of Sea Water. Part 1
In spite of the fact that many marine observers are aware that sea water has a remarkable foaming capacity, there has not been any scientific study of this subject. However, the foaming capacity may be of considerable importance in oceanography. For instance, there must be an intimate relation between the Beaufort scale and the foaming of sea water, since there is no doubt that aspects of white…

A Bathythermograph
In the study of the homogeneous layer in the ocean, Rossby1 found it desirable to have an instrument which would provide a continuous record of temperature against pressure in the surface layers of the ocean. A preliminary instrument named an "oceanograph" was constructed and used during the summer of 1934. The manifold uses to which such an instrument could be put presaged a widespread employm…

Iodine and Bromine in Sponges
Iodine and bromine have been known to occur in sponges since the early part of the nineteenth century. Since then a large number of analyses, primarily of the bath sponge but also of other sponges, have been reported. Both iodine and bromine have been found in most cases, although in greatly varying amounts.

Environmental Characteristics of a River Estuary
The Patuxent River is one of the larger tributaries of the Chesapeake 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 i…

Variations in The Phosphorus Content of Estuarine Waters of The Chesapeake Ba…
Studies by Cowles and Brambel (1938), Newcombe and Lang (1939), and Newcombe, Horne and Shepherd (1939) have provided information on the quantitative methods for estimating inorganic phosphorus and, also, on the vertical and horizontal distribution of this nutrient substance in the waters of the Chesapeake Bay. A continuation of distributional work has provided definite information on the …

A Study of Variability in Plankton Townet Catches of Pacific Pilchard (Sardin…
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 …
