The first full-scale oceanographic research expedition was conducted by the Challenger.
The first voyage to explore the ocean took place On 7 December 1872. The Challenger sailed into the deep ocean from Scotland and returned almost four years later, on 24 May 1876.
This marked the beginning of oceanography.
The main goal of the expedition was to investigate the physical conditions of the deep ocean, like temperature, penetration of light, circulation, among others.
