Monthly program update for the IODP
The devastating earthquake that struck Japan in 2011 may have unexpectedly released nearly all of the energy that had built up near the source of the resulting tsunami, new research suggests.
In the final week of October, the JOIDES Resolution set sail on Expedition 344 (Costa Rica Seismogenesis Project A Stage 2), also known as CRISP 2.
Earlier this month, the scientific drillship Chikyu drilled and collected samples from more than 2400 meters beneath the seafloor – setting a new world record for scientific ocean drilling – during Integrated Ocean Drilling Program (IODP) Expedition 337 (Deep Coalbed Biosphere off Shimokita).
Scientific deep sea drilling vessel Chikyu sets a world new record by drilling down and obtains rock samples from deeper than 2,111 meters below the seafloor off Shimokita Peninsula of Japan in the northwest Pacific Ocean.
This month, Brazil officially joined the Integrated Ocean Drilling Program (IODP), bringing the total membership to 26 countries on five continents.
The spring 2012 issue of Core Discoveries, the newsletter for U.S. scientific ocean drilling, is now available. This issue includes articles about the Chikyu breaking the scientific record at the Japan Trench, the JOIDES Resolution targeting climate records in the North Atlantic, and education and diversity news.
The Chikyu embarked on Expedition 343 (Japan Trench Fast Drilling Project) on April 1. Later in the month, drilling operations set a new world record for scientific ocean drilling, surpassing the record of 7049.5 meters below the sea surface set by DSDP Leg 60 in the Marianas Trench in 1978.
Not only did we start collecting data for Expedition 343, we also set a new record in the process. Around 8:30 the next morning, Monica Wolfson, a morning shift watchdog, came by to say that the drilling was approaching the eagerly anticipated depth of 7049.5 meters below the sea surface.
