Scenes aboard the research ship "Glomar Challenger," as it commences drilling core samples from the deep ocean floor. View of the drill point being lowered from the ship's drill rig. Sections of drill pipe are connected to one another. Drilling proceeds and then the drill is retrieved. Crew extracts a drilling core which is registered, labeled, and weighed. It is examined by means of instruments. Drilling crew continues to retrieve and extract drilling cores, which are examined in detail in the shipboard laboratories.
Core samples from deep ocean floor are placed in laboratory oven on board the research vessel, Glomar Challenger. Brief view of the ship at sea.
