Researchers drill historic hole in Atlantic Ocean floor

29.04.2005


Researchers from the Integrated Ocean Drilling Program (IODP) have drilled into sections of the Earth’s crust for the first time ever, and their findings could provide new insights about how Earth was formed.



Scientists aboard the research vessel JOIDES Resolution, of which Texas A&M University serves as the chief contractor, took almost three months to drill the hole, which penetrates more than 4,600 feet below the ocean floor. It is in an area called the Atlantis Massif located in the middle of the Atlantic Ocean, says Jay Miller, staff scientist at Texas A&M and one of the leaders of the project.

The new hole - the third deepest ever drilled in the "basement" area of the oceanic crust - has provided more than 3,000 feet of core samples that researchers will examine over the next three to four years, Miller said. It could provide key data on how ocean crust and other layers form, and the research may yield new perspectives on how the ocean crust was formed and has evolved through time.


"What we know about how the interior of the Earth evolved is based primarily on geophysical data," Miller explains.

"The samples we’ve collected lead us to believe that we’ve oversimplified some features. We know now that each time we drill a hole, we learn the structure of the Earth is much more complex than we had thought. Much of this drilling work is changing our understanding of how the Earth developed."

Drilling during the expedition, which was completed in early March, lasted 24 hours a day through solid rock, Miller said. Research teams from IODP’s members (the United States, Japan, China and the European Consortium for Ocean Research) involved 18 different countries.

Miller said the core samples will be analyzed and additional drilling could be possible. "The area where we were is sort of a mountain on the ocean floor," he explains. "The data from where we drilled also need to be studied thoroughly so we can develop a model to work from. This could provide us with a window to parts of the oceanic crust we’ve never seen. "From these samples, we hope to assemble pictures and data of what the entire ocean crust looks like. This hole we’ve drilled is just one part of the big puzzle below the ocean floor."

Miller said the 4,600-foot hole "is still there, open and in good condition. We could return to it at any time in the future and deepen it."

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
