3. Chapter I Chapter I A Brief History of Scientific Drilling 3

4. Scientists have been using drilling technology to understand Earth’s history and dynamics since 1958.  Project Mohole (1958 -1966): Historic  Deep Sea Drilling Project (1968 -1983): Linear  Ocean Drilling Program (1985 - 2003): Collaborative  Integrated Ocean Drilling Program (2003 – 2013): Global  International Ocean Discovery Program (2013 - ): Global Drilling for Science

5. Project Mohole attempted to drill through Earth’s oceanic crust to the Mohorovicic Discontinuity and retrieve a sample of the mantle. Project Mohole recovered the first sample of oceanic crust. Although the mantle was never reached, Project Mohole showed that deep ocean drilling was a viable means of obtaining geological samples. Project Mohole IODP-MI

6. During worldwide operations, Glomar Challenger sailed 96 Legs and drilled 624 sites. Deep Sea Drilling Project(DSDP) 1968-1983 IODP-MI

7. DSDP: Verified the theory of plate tectonics; Discovered that Antarctica has been ice-covered for 20 million years; Showed that the Mediterranean Sea completely dried up between 5 and 12 Mya. DSDP Scientific Highlights IODP-MI

8. During ODP, the JOIDES Resolution sailed 110 Legs and drilled 650 sites. Ocean Drilling Program(ODP) 1985-2003 IODP-MI

9. ODP: Defined the longest record of Earth’s natural climate variability; Collected the first marine record of the K/T boundary; Successfully sampled gas hydrates. ODP Scientific Highlights IODP-MI

10. The Integrated Ocean Drilling Program was the most ambitious of these scientific drilling programs involving:  International partnerships  Multiple Drilling Platforms  Well-defined scientific goals Integrated Ocean Drilling Program (IODP)
