Expedition 335: Superfast Spreading Rate Crust 4

Dates: April 17, 2011 - June 3, 2011

Location: Leaving from Puntarenas, Costa Rica and ending in Balboa, Panama

Co-chief scientists: Damon Teagle (University of Southampton); Benoit Ildefonse (Université Montpellier 2)

Staff Scientist: Peter Blum

Logging Staff Scientist: Gilles Guerin

Outreach Officers: Sarah Saunders (USIO), Sarah McNaboe (Scientific Illustrator)

Following three previous expeditions to the same site, Expedition 335 "Superfast Spreading Rate Crust 4," has returned to ODP (Ocean Drilling Program) Hole 1256D. This site lies about 900 kilometers west of Costa Rica, in 15 million-year-old ocean crust dating back to a period of "super-fast" ocean crust formation -- when the crust was forming at a faster rate than any ocean spreading occurring on our planet today.  Hole 1256D currently penetrates about 1500 meters below the seafloor, and reaches the base of the upper, volcanic crust. This expedition will continue the mission to understand the formation of oceanic crust by deepening Hole 1256D and studying the magmatic rocks of the lower crust.
