Chapter I

A Brief History of Scientific Drilling

3

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

•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

During worldwide operations, Glomar Challenger sailed 96 Legs and

drilled 624 sites.

Deep Sea Drilling Project(DSDP)1968-1983

IODP-MI

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

During ODP, the JOIDES Resolution sailed 110 Legs and drilled 650 sites.

Ocean Drilling Program(ODP)1985-2003

IODP-MI

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

•The Integrated Ocean Drilling Program was the most ambitious of these scientific drilling programs involving:

International partnerships Multiple Drilling Platforms Well-defined scientific goals
