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 (Classic Reprint)

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.
