Why were cores drilled in the sea floor from the Glomar Challenger?
One of the most important discoveries was made during Leg 3. The crew drilled 17 holes at 10 different sites along a oceanic ridge between South America and Africa. The core samples retrieved provided definitive proof for continential drift and seafloor renewal at rift zones.
How did drilling by the Glomar Challenger support seafloor spreading?
Purpose. Glomar Challenger was made to help Harry Hess with the theory of Seafloor Spreading by taking rock samples confirming that the farther from the Mid-ocean ridge, the older the rock was.
What was the purpose of the Glomar Challenger?
Above: The Glomar Challenger was the first research vessel specifically designed in the late 1960s for the purpose of drilling into and taking core samples from the deep ocean floor.
What was the purpose of the Glomar Challenger and JOIDES Resolution?
In 1985 the work of the Glomar Challenger was continued by the JOIDES Resolution, a larger and more advanced drilling ship of the Joint Oceanographic Institutions for Deep Earth Sampling.
What is the purpose of ocean drilling?
Scientific ocean drilling is the process of drilling cores of rock and/or sediment from below the seafloor and bringing them to the surface for study. Scientists can analyze these cores and install sensors in the boreholes left after drilling to learn about the geology, chemistry, and biology of Earth.
What are the objectives of Ocean Drilling Program?
The primary scientific objectives of the ODP lie in studying the origin and evolution of the oceanic crust, the tectonic evolution of the continental margins, the origin and evolution of marine sedimentary sequences, studies of long term changes in the atmosphere, oceans, cryosphere, biosphere, and magnetic field, and …
How did drilling samples show that seafloor spreading really has taken place?
They found that the farther away from the ridge the samples were taken, the older the rocks were. The youngest rocks were always in the center of the ridges. This showed that sea- floor spreading really has taken place.
What is the purpose of deep sea drilling?
As for the purpose of the scientific exploration, one of the most important discoveries was made when the crew drilled 17 holes at 10 different locations along an oceanic ridge between South America and Africa. The retrieved core samples provided strong proof for continental drift and seafloor renewal at rift zones.
Where is the Glomar Challenger now?
The Glomar Explorer returned to Long Beach in September 1974 with a number of crates recovered from the sub. The sub itself was transported to the naval submarine base in Bangor, Washington.
What is the most important discovery of Ocean Drilling Program?
As for the purpose of the scientific exploration, one of the most important discoveries was made when the crew drilled 17 holes at 10 different locations along an oceanic ridge between South America and Africa.
What is the most important discovery of ocean Drilling Program?
What is the most important discovery in Ocean Drilling Program?
How does offshore drilling affect the environment?
Toxic Pollution: Normal offshore drilling operations release toxic pollution into the air and water. Exploration and drilling at the platform, transportation via tankers, and refining the oil on land can all release volatile organic compounds, greenhouse gases, and other air pollutants.
What countries are involved in Ocean Drilling Program?
ODP was an international effort with contributions of Australia, Germany, France, Japan, the United Kingdom and the ESF Consortium for Ocean Drilling (ECOD) including 12 further countries.
How did drilling into the sea floor contribute further proof of sea floor spreading How did the sea floor spreading hypothesis explain variations in ocean floor heat flow?
How did the sea-floor spreading hypothesis explain variations in ocean floor heat flow? Drilling into the sea floor brought up rocks that could be tested to see how old they are and to prove that as the rocks get further from the mid-ocean ridge and hence must have resulted from sea-floor spreading.
How has deep sea drilling tested the concept of plate motion?
Ocean Drilling Samples This showed that new oceanic crust was being formed along the plate boundary and then spreading out laterally, just like the seafloor spreading theory proposed.
What is the advantage or benefit of deep sea drilling?
Offshore Drilling Rigs Pros Increases Oil Production: Since the advent of offshore drilling technology, petroleum production has grown to sustain the rising demand. Promotes Energy Independence: With offshore drilling, many foreign countries can now explore the ocean for oil and gas, promoting self-reliance.
What does Glomar stand for?
Global Marine
“Glomar” is the syllabic abbreviation of Global Marine, the company commissioned by the CIA to build the Glomar Explorer.
Does the Glomar Explorer still exist?
Howard Hughes and the covert CIA project to raise a lost Soviet sub in early 1970s. The Glomar Explorer, once the world’s most advanced deep water drill ship, ended up in a scrap yard in Zhoushan, China, in 2015. But it left behind two remarkable offshore exploration histories.
What are the objectives of the Ocean Drilling Program?
When did the Glomar Challenger go to the ocean?
Written By: Glomar Challenger, oceanographic drilling and coring vessel, active from 1968 to 1983. The exploratory ship of the Deep Sea Drilling Project (later the Ocean Drilling Project; ODP), it was equipped with a drilling derrick 43 metres (140 feet) high and was capable of drilling more than 1,700 metres (5,570 feet) into the ocean floor.
What is the purpose of the Glomar Challenger?
Glomar Challenger. Glomar Challenger was a deep sea research and scientific drilling vessel for oceanography and marine geology studies. The drillship was designed by Global Marine Inc. (now Transocean Inc.) specifically for a long term contract with the American National Science Foundation and University of California Scripps…
What is the name of the ship that was used for drilling?
Glomar Challenger, oceanographic drilling and coring vessel, active from 1968 to 1983.

How deep in the ocean can a Glomar Explorer Go?
For the CIA ship used to recover a sunken Soviet submarine during the Cold War, see Glomar Explorer. Can drill to a depth of 22,500 ft (6,900 m), in a water depth of up to 20,000 ft (6,100 m). Glomar Challenger was a deep sea research and scientific drilling vessel for oceanography and marine geology studies.
