HMS Challenger (expedition)

The HMS Challenger expedition (1872-1876) was a groundbreaking scientific voyage that systematically explored the world's oceans for the first time. Sponsored by Britain, it aimed to gather comprehensive data on underwater geology, chemistry, and biology. Over four years, Challenger traveled thousands of miles, collecting samples and making discoveries about deep-sea environments. This pioneering expedition laid the foundation for modern oceanography, significantly expanding our understanding of marine life and the ocean floor, and establishing methods for future oceanic research.
