From Deep Sea to Laboratory 2

Discovering H.M.S. Challenger's Physical Measurements Relating to Ocean Circulation

• Gebundenes Buch

Produktbeschreibung

The scientific expedition of H.M.S. Challenger in the 1870s marks the starting point of physical oceanography. This ship traveled the seas of the globe pursuing a dual objective: to conduct an in-depth study of animal life and to observe the physical properties of ocean waters. Volume 2 analyzes and uses for the first time the physical measurements collected by the scientists of the Challenger to show that their surveys establish the link between ocean circulation and the distribution of the ocean's temperature. From Deep Sea to Laboratory is available in three volumes for curious readers drawn to travel, history and science. Students, researchers and teachers of physics, fluid mechanics and oceanography will find material to deepen their knowledge.
