The first study to ever explore biological activity in the deepest layer of ocean crust has found bacteria with a remarkable range of capabilities, including eating hydrocarbons and natural gas, and "fixing" or storing carbon. The research, published in the journal PLoS One, showed that a significant number and amount of bacterial forms were present, even in temperatures near the boiling point of water. "This is a new ecosystem that almost no one has ever explored," said Martin Fisk, a...

Scientists will study fluid flow, chemistry, and life off British Columbia coast Marine geologists have returned from two months at sea off British Columbia, Canada, where they installed two observatories in the ocean floor to run innovative experiments at the bottom of the sea. The Integrated Ocean Drilling Program (IODP) "Juan de Fuca Ridge-Flank Hydrogeology" expedition--Expedition 327--left Victoria, Canada, on July 9th and returned on September 5th. Using the scientific research vessel...

The poles control much of our global climate. Giant ice sheets in Antarctica behave like mirrors, reflecting the sun's energy and moderating the world's temperatures. The waxing and waning of these ice sheets contribute to changes in sea level and affect ocean circulation, which regulates our climate by transporting heat around the planet. Despite their present-day cold temperatures, the poles were not always covered with ice. New climate records recovered from Antarctica during the recent...

The eruptions of "supervolcanoes" on Earth's surface have been blamed for causing mass extinctions, belching large amounts of gases and particles into the atmosphere, and re-paving the ocean floor. The result? Loss of species, increased greenhouse gases in the atmosphere, and changes in ocean circulation. Despite their global impact, the origin and triggering mechanism of these eruptions remain poorly understood. New data collected during a recent Integrated Ocean Drilling Program (IODP)...

Ancient goliaths blamed for multiple mass extinctions "Supervolcanoes" have been blamed for multiple mass extinctions in Earth's history, but the cause of their massive eruptions is unknown. Despite their global impact, the eruptions' origin and triggering mechanisms have remained unexplained. New data obtained during a recent Integrated Ocean Drilling Program (IODP) expedition in the Pacific Ocean may provide clues to unlocking this mystery. To explore the origins of these seafloor giants,...

The chemical composition of our oceans is not constant but has varied significantly over geological time. In a study published this week in Science, researchers describe a novel method for reconstructing past ocean chemistry using calcium carbonate veins that precipitate from seawater-derived fluids in rocks beneath the seafloor. The research was led by scientists from the University of Southampton's School of Ocean and Earth Science (SOES) hosted at the National Oceanography Centre,...

Ocean drilling expedition off New Zealand helps predict global sea level changes For eight weeks beginning in November 2009, off the coast of New Zealand, an international team of 34 scientists and 92 support staff and crew on board the scientific drilling vessel JOIDES Resolution (JR) were at work investigating sea-level change in a region called the Canterbury Basin. It proved to be a record-breaking trip for the research team. The JR is one of the primary research vessels of an...

Water in Earth's critical zone; declining water resources in the U.S. west; "zebra stripes" in rock; dark energy under the sea-floor; undersea volcanic eruptions; Sumatra earthquake zone among topics Society stands at a crossroads. With growing problems such as resource depletion, energy sustainability, environmental degradation and climate change, can we protect the health of the planet while achieving widespread economic prosperity? This and other questions will be addressed at the fall...

IODP Expedition 322 of the Nankai Trough Seismogenic Zone Experiment Stage 2 complete An international group of scientists aboard the Deep-Sea Drilling Vessel CHIKYU, operated by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) for the Integrated Ocean Drilling Program (IODP), return from a 40-day scientific expedition off the shore of the Kii Peninsula, Japan on Oct. 10, 2009. Expedition 322, called "Subduction Inputs" in the multi-stage project, conducted drilling, logging...

The future of scientific ocean drilling Close to 600 scientists from 21 countries met Sept. 23 "“ 25 2009 in Bremen, Germany, to outline major scientific targets for a new and ambitious ocean drilling research program. The scientific community envisions that this program will succeed the current Integrated Ocean Drilling Program (IODP), which ends in 2013. The outcome of the Bremen meeting will result in a new science plan, enabling scientific ocean drilling to take on a central role in...
