This book was released on 2018-05-14 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: A history of the American Steel Barge Company and the vessels that it built and operated. The whaleback ship reflected the experiences of its inventor, Captain Alexander McDougall, who decided in the 1880s that he could build an improved and easily towed barge cheaply by using the relatively unskilled labor force available in his adopted hometown of Duluth, Minnesota. Captain McDougall’s dream resulted in the creation of the American Steel Barge Company. From 1888 to 1898, the American Steel Barge Company built and operated a fleet of forty-four barges and steamships on the Great Lakes and in international trade. These new ships were considered revolutionary by some and nautical curiosities by others. Built from what was then a high tech material (steel) and powered by state-of-the-art steam machinery, their creation in the remote north was a sign of industrial accomplishment. In Whaleback Ships and the American Steel Barge Company, Roger C. Pellett explains that the construction of these ships and the industrial infrastructure required to build them was financed by a syndicate that included some of the major players active in the Golden Age of American capitalism. The American Steel Barge Company operated profitably from 1889 through 1892, each year adding new vessels to its growing fleet. By 1893, it had run out of cash. The cash crisis worsened with the onset of the Panic of 1893, which plunged the country into a depression that mostly halted the ship-building industry. Only one shareholder, John D. Rockefeller, was willing and able to invest in the company to keep it afloat, and by doing so he gained control. When prosperity returned in 1896, the interest in huge iron ore deposits on the Mesabe Range required larger, more efficient vessels. In an attempt to meet this need, the company built another vessel that incorporated many whaleback features but included a conventional Great Lakes steamship bow. Although this new steamship compared favorably with vessels of conventional design, it was the last vessel of whaleback design to be built. Whaleback Ships and the American Steel Barge Company objectively examines the design of these ships using the original design drawings, notes the successes and failures of the company’s business strategy, and highlights the men at the operating level that attempted to make this strategy work. Readers interested in the maritime history of the Great Lakes and the industries that developed around them will find this book fascinating.
Download or read book Lakes on Mars written by Nathalie A. Cabrol and published by Elsevier. This book was released on 2010-09-15 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: On Earth, lakes provide favorable environments for the development of life and its preservation as fossils. They are extremely sensitive to climate fluctuations and to conditions within their watersheds. As such, lakes are unique markers of the impact of environmental changes. Past and current missions have now demonstrated that water once flowed at the surface of Mars early in its history. Evidence of ancient ponding has been uncovered at scales ranging from a few kilometers to possibly that of the Arctic ocean. Whether life existed on Mars is still unknown; upcoming missions may find critical evidence to address this question in ancient lakebeds as clues about Mars' climate evolution and its habitability potential are still preserved in their sedimentary record. Lakes on Mars is the first review on this subject. It is written by leading planetary scientists who have dedicated their careers to searching and exploring the questions of water, lakes, and oceans on Mars through their involvement in planetary exploration, and the analysis of orbital and ground data beginning with Viking up to the most recent missions. In thirteen chapters, Lakes on Mars critically discusses new data and explores the role that water played in the evolution of the surface of Mars, the past hydrological provinces of the planet, the possibility of heated lake habitats through enhanced geothermal flux associated with volcanic activity and impact cratering. The book also explores alternate hypotheses to explain the geological record. Topographic, morphologic, stratigraphic, and mineralogic evidence are presented that suggest successions of ancient lake environments in Valles Marineris and Hellas. The existence of large lakes and/or small oceans in Elysium and the Northern Plains is supported both by the global distribution of deltaic deposits and by equipotential surfaces that may reflect their past margins. Whether those environments were conducive to life has yet to be demonstrated but from comparison with our planet, their sedimentary deposits may provide the best opportunity to find its record, if any. The final chapters explore the impact of climate variability on declining lake habitats in one of the closest terrestrial analogs to Mars at the Noachian/Hesperian transition, identify the geologic, morphologic and mineralogic signatures of ancient lakes to be searched for on Mars, and present the case for landing the Mars Science Laboratory mission in such an environment. - First review on the subject by worldwide leading authorities in the field - New studies with most recent data, new images, figures, and maps - Most recent results from research in terrestrial analogs

Download or read book Paleolimnology written by Andrew S. Cohen and published by Oxford University Press. This book was released on 2003-05-29 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text, written by a leading researcher in the field, describes the origin and formation of lakes in order to give context to the question of how lacustrine deposits form. It explains the process of sedimentation in lakes and the chemistry of those deposits and describes how the age of lake deposits are determined. Additionally, this book shows how different groups of fossils are used in interpreting the paleontological record of lakes. In order to illustrate the more synthetic approaches to interpreting the history of lakes, the author also discusses such special topics as lake-level history, lake evolution, and the impact of environmental change on lakes.
