Scientific ocean drilling in the Australasian region: a review
Extensive scientific ocean drilling in the Australasian region for 50 years has generated public-domain geoscience knowledge on a scale that no other science program could. Predominantly continuous coring, commonly to depths of 1000 m or more below the sea bed, has revealed the nature and origin of...

Extensive scientific ocean drilling in the Australasian region for 50 years has generated public-domain geoscience knowledge on a scale that no other science program could. Predominantly continuous coring, commonly to depths of 1000 m or more below the sea bed, has revealed the nature and origin of the continental margins, the plateaus and ridges, and the deep ocean, and put them into their plate-tectonic context. Many Australian and New Zealand scientists have played important roles in the 50 two-month regional expeditions, including building the international proposals that led to them. Large International teams aboard ship exchanged ideas and often formed long-term scientific partnerships. Most are not formally marine geoscientists or marine microbiologists.
