When was the first core sample from the deep ocean floor collected?
Quick Answer
The landmark deep-sea coring work began in the 1950s, especially with the Glomar Challenger era later in the 1960s and 1970s.
The Full Story
Deep ocean core sampling developed in the mid-20th century as scientists sought direct evidence of seafloor history. Early coring efforts expanded rapidly during the 1950s, and the Deep Sea Drilling Project using the Glomar Challenger began in 1968. These cores revealed patterns of ocean-crust age, sedimentation, and climate change. The samples became crucial evidence for plate tectonics and Earth’s past climate.
