Heavy Metal Meets Hard Rock: Battling through the Ocean Crust's Hardest Rocks to Capture the Boundary Between Magma and Water Scientists and drillers recovered a remarkable suite of heat-tempered basalts that provide a detailed picture of the rarely seen boundary between magma and seawater. These samples were collected during a return to ODP Hole 1256D, one of the deepest "hard rock" penetration sites of scientific ocean drilling. ODP Hole 1256D has been stabilized, cleared to its full depth,...

The Chicxulub crater in Mexico, the site of the asteroid strike that brought the dinosaurs to extinction 65 million years ago, is among the highlights of ocean drilling projects proposed for the next decade, reports BBC News. The Integrated Ocean Drilling Program (IODP) plans to study the crater by drilling about a mile into the sea bed. IODP is also planning expeditions to study earthquakes, ancient climates and a long-term aim to penetrate the Earth's mantle for the first time. IODP...

Scientists return from first ever riser drilling operations in seismogenic zone The Deep-sea Drilling Vessel CHIKYU successfully completed riser drilling operations on Aug. 31, for IODP Expedition 319, Stage 2 of the Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE). The CHIKYU is operated by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) in partnership with the Integrated Ocean Drilling Program. The expedition began with drilling operations at the Kumano Basin, off...

Cores provide new data source on how earthquakes are generatedThe third expedition of the Integrated Ocean Drilling Program's Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) completed its mission off the Kii Peninsula today. The expedition science party, 26 scientists representing 10 countries, set forth on Dec. 19, 2007, aboard the drilling vessel Chikyu, to evaluate the deformation, structural partitioning, and physical characteristics of the Nankai Trough fault zone. The expedition...

Rice's Sawyer, colleagues search Nankai Trough for quake clues Rice University Earth scientist Dale Sawyer and colleagues last month reported the discovery of a strong variation in the tectonic stresses in a region of the Pacific Ocean notorious for generating devastating earthquakes and tsunamis in southeastern Japan. The results came from an eight-week expedition by Sawyer and 15 scientists from six countries at the Nankai Trough, about 100 miles from Kobe, Japan. Using the new scientific...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
