Expedition 328: Cascadia ACORK
Dates: 5 September 2010 - 19 September 2010
Co-Chief Scientist: Earl Davis
Staff Scientist: Mitch Malone
Staff Educator: Jennifer Collins (School of Rock principal)
The scientific purpose of Expedition 328 is to install a new subseafloor observatory (ACORK) at Site 889 that will monitor pressure at different depths in the ocean floor over time. The information recorded will be used to study a broad range of objectives and help us better understand gas hydrate formation in a region where sediments are being deposited at a convergent plate boundary.
At a later date, submersibles will be used to deploy additional instruments such as sensors that record seafloor and formation pressure and downhole instruments that measure temperature, tilt, and seismic ground motion. These will be connected to a fiber-optic cable for power and real-time communications from land.
Expedition 328 is also host to the School of Rock 2010, Deep Earth Academy's signature professional development program for educators. During School of Rock, participants will spend 12-hour days working along-side a dynamite team of instructors and crew who will guide them in their own exploration of cores, CORKS, and logging data from the Cascadia region and beyond. Using the high-tech laboratories on board, and their own observational and problem-solving skills, they will be challenged to integrate diverse sets of data from deep in the ocean floor to recreate the geology and history of the Earth. Much of their experience will also involve developing programs and products that focus on their experience, the JOIDES Resolution, and scientific ocean drilling.
