A Possible Function of Bioluminescence

It has been found difficult in many cases to conceive a use of the light to the luminescent organism, despite the large number of possibilities of ecological significance which have been suggested (vide Mangold, 1910, pp. 326-32; Kemp, 1910, p. 649; Putter, 1911, p. 487; Harvey, 1920, pp. 81-4; Rauthcr, 1927, pp. 162-6; Harvey, 1942, pp. 58-87). This difficulty has led to the conclusion by some…

A Momentum Integral For Surface Waves in Deep Water

It has been demonstrated by the studies of Stokes (1847) and Lcvi-Civita (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 undisturb…

The Diatoms Collected By The U. S. S. Cacopan In The Antarctic In 1947

For investigation of the Diatomaceae, a series of water samples was collected from the U. S. S. Cacopan by filling a citrate bottle either with surface water obtained with a bucket or with water obtained from various depths with Nansen bottles. The positions at which samples were collected in the Antarctic are plotted on Fig. 1. Of the main previous Antarctic Expeditions (Challenger, Deuts…

Instituut Voor De Zeevissch Eru

Er zijn weinig Javaansche bedrijven, die zoo cenzijdig en wisselvallig blij- ken te zijn en waaraan zooveel inoeilijkheden zijn verbonden. als het door zeil- prauwen uitgeoefende zeevisscherijbedrijf. 1) Bij hooge zee of bij sterke tegen- wind kan niet worden uitgevaren. Soms kan door plotselinge windstilte het vischwater niet tijdig worden bereikt, dan wel kan men door den sterken stroom …

The Sex-Ratio in Alternational Hermaphrodites, with Special Reference to The …

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 which these differentials may operate…

Quantitative Studies of Summer Plankton Populations of The Western North Atla…

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 ar…

Annales Bogorienses

The year 1967 marks the 150th anniversary of the Bogor Botanic Garden. It was founded by C. G. C. Reinwardt on May 18, 1817. From this garden grew successively the Bibliotheca Bogoriensis in 1842, the Her barium Bogoriense in 1844, the Botanical Laboratory, which is known as the Treub Laboratory, in 1884, the Museum Zoologicum Bogoriense in 1894 and finally the Marine Research Laboratory i…

Note on the Use of the T-S Correlation for Dynamic Height Anomaly Computations

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. Since dynamic height anomaly computations require a knowledge of both the temperature and the salinity as functions of depth, it is the purpose of …
