摘要:

The Gulf Stream is a fascinating subject for research, not only because it is such a long and powerful current, but also because it is so difficult to study. It almost seems at times as if the current, knowing that an attempt is being made to discover its secrets, resists man's efforts just enough to keep him baffled. After two summer's work we have, for one reason or another, been unable to get even one hydrographic section that is entirely satisfactory. Twice the conditions have been obviously abnormal and our sections have crossed warm water flooding in over the continental shelf. Twice stormy weather has forced us to abandon a section before we had quite crossed the current. Finally several times we struck bands of water running so swiftly that it was impossible to tell at what depths our temperatures had really come from.

摘要:

Due to recently devised means for measuring ocean‐depths without stopping the ship or even reducing its speed, physical oceanography is today a subject of great importance to mariners and undoubtedly will be of more and more concern to them as the use of such apparatus becomes more general. I refer to the various types of echo‐sounding machines, which already are installed on many naval vessels, both American and foreign, and on a considerable number of commercial ships. One has but to read the enthusiastic reports of those ship‐masters who have used such apparatus in guiding their ships into port to be convinced that this new aid to navigation will “take” with merchant‐seamen, as it has with hydrographic surveyors and others, and that within the near future all “well‐found” ships will be provided wi

摘要:

In a recent book‐review, the writer‐critic spoke of science today as developing at an unprecedented and somewhat embarrassing rate, and indicated that, in consequence, there exists in current literature and thought a tendency to neglect the historical or humanistic aspect of scie

摘要:

This report (published in full under the title “Preliminary report of the cooperative survey of Lake Erie—season of 1928, in Bull. Buffalo Soc. Nat. Sci., v. 14, No. 3, 7–220, 1929) gave a preliminary statement of the results of a three‐month survey of eastern Lake Erie in 1928 to determine the cause or causes for the decline in the fish‐supply. The work was carried on under the joint auspices of the United States Bureau of Fisheries, the New York State Conservation Department, the Ontario Department of Game and Fisheries, the Health Department of the City of Buffalo, and the Buffalo Society of Natural Sciences. These five organizations pooled their resources, personnel, and equipment to function as a single unit, thus avoiding duplication of effort and offering maximum opportunities for coopera

摘要:

This paper (published essentially as given in Sci. Mon.,v. 29, 97–108, 1929) gave a brief, account of the program and route of theCarnegieduring the first year of the seventh cruise which began May 1, 1929. The principal object of the magnetic work has been restricted principally to the determination of secular variation. The atmospheric‐electric observations are even more extensive than on earlier cruises since this work had been inaugurated very much later than the magne

摘要:

In this paper a report is given of volcanological studies made in the islands of Java and Bali during the summer of 1928.This extensive volcanic area is an especially favorable region for such studies because the general geological and petrographic features of the islands have been determined and because excellent field work is being carried out by the volcanological survey (Vulkaandienst) located at Bandoeng, Java. The writer wishes to express his great appreciation for the hearty cooperation on the part of Dr. Ch. Stehn, the director of the Vulkaandienst, and all of his associates.

摘要:

The San Juan Mountains, which are made up chiefly of volcanic rocks, are located in southwestern Colorado and occupy a rudely circular area of over 10,000 square miles, or larger than the state of Massachusetts. They have been studied and mapped geologically by the United States Geological Survey, chiefly by field parties under Whitman Cross and Esper S. Larsen.

摘要:

The Hawaiian station in 1928 recorded 1,034 local disturbances on the seismograph. Possibly this heralded the outbreak of Halemaumau February 20, 1929. On that day lava, gushed up along a rift in the lava‐floor and the base of the talus‐slides. It was a pumiceous basalt spouting up in a jet for 200 feet. Fountains bubbled up along the crack, spread out in a lake, and filled the floor‐cup. They continued in action about 37 hours. About 3,600,000 cubic meters of lava flow
