Sinopsis

Exploring the Gulf Stream’s reach and the Arctic frontier
This translated collection presents the valuable papers on the eastern and northern extensions of the Gulf Stream, drawn from German sources and published for a 1870s U.S. Hydrographic Office audience. It tracks temperatures, currents, and the relationship between ocean flow and climate, with charts and observations from whaling regions and polar seas. The work is grounded in field notes, shipboard measurements, and careful comparisons of instruments and scales, offering a practical view of how early ocean science linked currents to navigation and weather.

The book compiles the German-era research into a single English edition, highlighting the methods, findings, and debates of the time. It emphasizes the role of maritime observations for understanding oceanic thermal structure, the Gulf Stream’s boundaries, and the interaction with polar waters. Readers gain a window into 19th‑century oceanography, including how data were collected, reduced, and interpreted for shipping and scientific inquiry.


  • Accounts of deep-sea temperatures and isothermal patterns across the North Atlantic

  • Descriptions of shipboard soundings, bottom samples, and microfossil findings

  • Discussions of the Gulf Stream’s influence on northern European climate and navigation

  • Context for polar and ocean-current research from multiple expeditions



Ideal for readers of historical oceanography, maritime science, and Arctic exploration, this edition provides a clear view of early efforts to map and understand the Gulf Stream and its northern reach.

The expedition, however, ascertained the temperature of the water, at a depth of fathoms, to be and at 2435 fathoms, still Compared with this, the deep-sea temperature of the Gulf of Arabia, and even of the waters under the Equator, 'will be found very low, sinking to 34 in general the deep-sea temperature of the tropical oceans is lower than that of the North Atlantic basin.

Excerpt from Papers on the Eastern and Northern Extensions of the Gulf Stream: From the German of Dr. A. Petermann, Dr. W. Von Freeden, and Dr. A. Mühry

Hydrographic Office, Washington, D. C., November 1870.

The valuable papers of Doctors Petermann, Von Freeden, and Mühry, on the eastern and northern extension of the Gulf Stream, are republished in translation; not only for the fund of information they contain, of interest both to science and to shipping, and especially to whalers and seal-fishers, but also, for the purpose of promoting the cooperation of the latter in the investigation of the relation of the currents and temperature of the northern seas.

It will be seen on the accompanying charts that comparatively few observations have been made, thus far, to the north of the ordinary routes between the United States and Great Britain. In those more northern fields the whaling, fleet is engaged at all times, frequently wintering there, and their masters have ample opportunities for making valuable observations, as, being on the spot, they are able to take advantage of those favorable openings which are so rare, and for which expeditions, sent out especially, have waited in vain.

The Hydrographic Office will cheerfully receive any records and make the most appropriate use of them, giving due credit to the contributors.

Information, as regards the observations required, the forms for records, &c., will be found in the following pages. The instruments used should, on the return, he compared with standards, and a foil description of them sent, with the record, in order that the observations may be properly reduced.

The temperatures, in the German text and on the original maps, were according to Réaumur; they have been reduced to Fahrenheit; the decimals have been dropped, and the nearest whole degree substituted to prevent crowding the maps. In the text they have been retained only where necessary.

The figures of reference in the text refer to the notes which will be found at the end of the work. These have been given in full, where the references were in the German language, or where the books referred to are difficult to obtain.

The remarks printed within brackets arc by the Hydrographic Oifice. R. H. Wyman, Captain U. S. N., in charge of Hydrographic Office.
