Ocean Magnetic and Electric Observations: 1915-1921

"Ocean Magnetic and Electric Observations, 1915-1921" represents a monumental achievement in the field of early 20th-century geophysics. This volume provides an exhaustive record of scientific data collected during the extensive global cruises of the research vessel Carnegie. Covering several years of maritime exploration, the work details critical measurements of magnetic declination, intensity, and inclination, alongside comprehensive atmospheric-electric observations conducted across the world's oceans.

Authored by J.P. Ault and S.J. Mauchly, the text offers a rigorous analysis of the methods, instruments, and results used to map the Earth's magnetic field with unprecedented precision. Scholars and researchers will find invaluable data regarding the electrical conductivity of the atmosphere and the potential gradient observed in remote oceanic regions. This collection serves as a foundational resource for understanding the historical development of oceanography and terrestrial magnetism. By documenting these complex physical phenomena, the work highlights the intersection of maritime navigation and theoretical physics, preserving a vital chapter in the history of international scientific collaboration and environmental observation.
