Banned from taking naval vessels to foreign ports after WW1 Germany undertakes a comprehensive oceanographic expedition to the Atlantic Ocean to test many new measurement systems and to establish the long term circulation patterns of the Atlantic. Challenged by the proscription on German naval vessels from visiting foreign ports after WW1 a group of German oceanographers from the Institute for Marine Sciences in Berlin carried out a pioneering research expedition from 1925-27 to sample the hydrographic structure of the South Atlantic Ocean. Its captain Fritz Spiess was the primary driving force behind the expedition and the German navy supplied the survey ship Meteor. During this 2.5 year expedition the Meteor scientists tested a great many new measurement systems many of which later became routine oceanographic measurement systems. As a result of their observations the mean circulation pattern of the Atlantic was revealed that has remained valid to this day. People interested in the history of ocean exploration, the history of Earth science and German scientific activity between the World Wars will find this volume to be an intriguing read. Much of the book has been taken from the original cruise report written by Captain Fritz Spiess (1933). In addition, his role has been expanded to demonstrate his essential contribution to the creation of the expedition, its execution and the dissemination of its results upon completion. The present text comments on the captain’s life before and after the expedition. In 1934 Fritz Spiess started his second carrier as President of the German Marine Observatory (Deutsche Seewarte) in Hamburg. A great number of so far unpublished documents demonstrate Spiess’s ability to run his dignified agency in the turbulent times of Nazi Germany without becoming a Nazi himself. Readers will learn how this first ocean expedition, dedicated to the study of the physics a whole ocean basin, helped to provide the background for modern physical oceanography.

This book is dedicated to the analysis of bottom waters flows through underwater channels of the Atlantic Ocean. The study is based on recent observations of the authors, analysis of historical data, numerical modeling, and literature review. For example, studying both the measurements from the World Ocean Circulation experiment in the 1990s and recent measurements reveals the decadal variations of water properties in the ocean. Seawater is cooled at high latitudes, descends to the ocean bottom, and slowly flows to the tropical latitudes and further. This current is slow in the deep basins, but intensifies in the abyssal channels connecting the basins. The current overflows submarine topographic structures and sometimes forms deep cataracts when water descends over slopes by several hundred meters. The flow of Antarctic Bottom Water (AABW) is studied on the basis of CTD sections combined with Lowered Acoustic Doppler Profiling (LADCP) carried out annually, and long-term moored measurements of currents. This book is a collection of oceanographic data, interpretation, and analysis, which can be used by field oceanographers, specialists in numerical modeling, and students who specialize in oceanography.

In the summer of 1803, Thomas Jefferson sent Meriwether Lewis and William Clark on a journey to establish an American presence in a land of unqualified natural resources and riches. Is it fitting that, on the 200th anniversary of that expedition, the United States, together with international partners, should embark on another journey of exploration in a vastly more extensive region of remarkable potential for discovery. Although the oceans cover more than 70 percent of our planet's surface, much of the ocean has been investigated in only a cursory sense, and many areas have not been investigated at all. Exploration of the Seas assesses the feasibility and potential value of implementing a major, coordinated, international program of ocean exploration and discovery. The study committee surveys national and international ocean programs and strategies for cooperation between governments, institutions, and ocean scientists and explorers, identifying strengths, weaknesses, and gaps in these activities. Based primarily on existing documents, the committee summarizes priority areas for ocean research and exploration and examines existing plans for advancing ocean exploration and knowledge.

NEW YORK TIMES BESTSELLER • Turn: Washington’s Spies, now an original series on AMC Based on remarkable new research, acclaimed historian Alexander Rose brings to life the true story of the spy ring that helped America win the Revolutionary War. For the first time, Rose takes us beyond the battlefront and deep into the shadowy underworld of double agents and triple crosses, covert operations and code breaking, and unmasks the courageous, flawed men who inhabited this wilderness of mirrors—including the spymaster at the heart of it all. In the summer of 1778, with the war poised to turn in his favor, General George Washington desperately needed to know where the British would strike next. To that end, he unleashed his secret weapon: an unlikely ring of spies in New York charged with discovering the enemy’s battle plans and military strategy. Washington’s small band included a young Quaker torn between political principle and family loyalty, a swashbuckling sailor addicted to the perils of espionage, a hard-drinking barkeep, a Yale-educated cavalryman and friend of the doomed Nathan Hale, and a peaceful, sickly farmer who begged Washington to let him retire but who always came through in the end. Personally guiding these imperfect everyday heroes was Washington himself. In an era when officers were gentlemen, and gentlemen didn’ t spy, he possessed an extraordinary talent for deception—and proved an adept spymaster. The men he mentored were dubbed the Culper Ring. The British secret service tried to hunt them down, but they escaped by the closest of shaves thanks to their ciphers, dead drops, and invisible ink. Rose’s thrilling narrative tells the unknown story of the Revolution–the murderous intelligence war, gunrunning and kidnapping, defectors and executioners—that has never appeared in the history books. But Washington’s Spies is also a spirited, touching account of friendship and trust, fear and betrayal, amid the dark and silent world of the spy.
