Sinopsis
Excerpt from A Practical Method for Determining Ocean Currents
This paper endeavors to encompass in a general way the foregoing subject with its various aspects. The contents deal with the fol lowing: The causes of currents; static consideration of a water mass; dynamics and Bjerknes' theory; and a practical method for mapping currents. Other related subjects discussed are friction; effect of bottom configuration; tides; variations in atmospheric pressures; and the winds. The writer has tried to present a rather technical scientific subject in such a manner that it may easily be understood by the ordinary student. Always there has been the hope that the methods elucidated herein would serve some practical economic service.
I wish to recognize with appreciation the advice and suggestions made with regard to this paper by the curator of the Museum of Comparative Zoology, Harvard University, and the hydrographic engineer, United States Hydrographic Office.

Excerpt from A Practical Method for Determining Ocean Currents
The following paper has been compiled from a series of lecture notes made by the writer when he took an advanced course on oceanography under Prof. Bjorn Helland-Hansen, Geo-Physical Institute, Bergen, Norway. Writers of textbooks on oceanography, fail from time to time, due to the rapid growth of this science, to keep pace in print with the newest methods in practice. The need for the appearance of the present treatise is emphasized when it is realized that a complete exposition of the methods elucidated herein has never before, to the Writer's knowledge, been collected in a single publication, and the particular hydrographical information, prior to this, has been unavailable short of personal instruction in Europe. Although the illustrations to be found throughout the paper are in most cases examples taken from observations of the International Ice Patrol off Newfoundland, and although the bulletin is intended especially to assist the prosecution of Ice Patrol service, the application of the text is, nevertheless, quite broad in its scope. It is therefore recommended to the attention of all students interested in the subject of physical oceanography.
The foundation upon which this paper rests was first laid down by Prof. V.Bjerknes, (see "Dynamic Meteorology and Hydrography," Carnegie Institution publications, Washington, 1910-11).In the lines of history which record attempts to apply mathematics to the natural sciences this treatise by Bjerknes stands out as one of the most successful and progressive. A perusal of the book can not fail to impress one with the infinite care and exactitude with which the theories have been presented and the exposition developed. It is a model of scientific treatment, but he who is searching for a practical method directly applicable to a hydrographical problem is bound to note the absence of just this sort of pertinent information. Since the time when Bjerknes theories became recognized by scientists there have been a few oceanographers, especially Helland-Hansen, Nansen, Ekman, and Sandstrom, who have done much to give the formulæ of motion a practical application to the sea. As a result of such development we are now supplied with a scientific method whereby if the temperature and salinity of the ocean are given from several known depths and stations the direction and velocity of the currents even in the deep water off soundings can be computed and mapped. In this connection it may be of interest to know that the currents calculated from the observational data collected in 1922 off the Grand Banks have been found to agree very closely with the drifts of the icebergs of that same year and region.

A Practical Method for Determining Ocean Currents (Classic Reprint)
Impresión bajo demandaLibrería: Forgotten Books, London, Reino Unido
Calificación del vendedor: 4 de 5 estrellas
Paperback. Condición: New. Print on Demand. This book explores the origins of ocean currents, revealing earth's rotation and variations in atmospheric pressure as their fundamental causes. The author, a renowned oceanographer, uses dynamic principles to explain ocean circulation, discussing the interplay between gravity, pressure, and specific volume in driving currents. Through an in-depth examination of density and temperature distributions, the book sheds light on the stability and motion of water masses. It also investigates the effects of tides and wind on currents, providing a comprehensive understanding of the dynamic processes shaping ocean circulation. Overall, this book offers a valuable resource for students, researchers, and anyone interested in unraveling the mysteries of the ocean's currents and their role in shaping our planet. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Nº de ref. del artículo: 9781332306879_0
