We have drilled 2,600 feet below the sea floor and in another 500 feet, will reach the crystalline igneous basalt of the ocean crust. Though finding the age of the basalt is our main aim, the thick sediments that overly the crust also have a story to tell.
Opening the South China Sea
Team: Trevor J. Williams
Purpose: Marine Tectonics
Start Date: Jan. 27-March 30, 2014
The South China Sea is one of the most geopolitically contested marine realms on earth. But it is also of keen interest to geologists who want to understand how this ocean basin, bordered by China, the Philippines, Malaysia and Vietnam, opened up. On an International Ocean Discovery Program cruise aboard the JOIDES Resolution, scientists will drill through seafloor sediments to understand how the basin reached its present form. Marine geologist Trevor Williams of Lamont-Doherty Earth Observatory is directing downhole logging operations. Follow his dispatches from the ship here.
