New SCOR Working Group: "Hydrothermal energy transfer and its impact on ocean carbon cycles"

InterRidge is pleased to announce the approval of a new SCOR Working Group in Oct. 2008, to be co-funded by InterRidge, on "Hydrothermal energy transfer and its impact on ocean carbon cycles." This new Working Group (SCOR WG 135) is co-chaired by Nadine Le Bris (IFREMER, France) and Chris German (WHOI, USA). The proposal was developed from discussions at the InterRidge Theoretical Institute (IRTI) on Biogeochemical Interaction at Deep-Sea Vents, held in September 2007.

IODP Call for Scientific Ocean Drilling Proposals

The Integrated Ocean Drilling Program (IODP) explores Earth's history, structure, dynamics and deep biosphere through seafloor drilling, coring and downhole measurements. Multiple drilling platforms - operated by three partners in the USA, Japan, and Europe - include riser drilling technology, and permit operations in a variety of environments. Approximately two years of drilling currently remain before the current phase of IODP ends in 2013. Truly innovative and mature proposals can still be incorporated into the current drilling program.

Discovery of world’s most northerly black smokers at 73°N

The InterRidge Office has just received news that the world's most northerly black smoker hydrothermal vent field was discovered at 2400m in the North Atlantic at 73°N. The discovery occurred on July 12, 2008, during a cruise led by Rolf B. Pedersen, Professor of Geology and leader of the Centre for Geobiology at the University of Bergen, Norway. The cruise included PIs from Norway, Portugal, Switzerland, and USA.

Daily dispatches from multi-disciplinary cruise to the Mid-Atlantic Ridge

A multi-disciplinary cruise aboard the R/V Revelle with ROV Jason II is underway at the Mid-Atlantic Ridge from 9 July - 8 August 2008. The cruise includes three science teams, led by scientists Anna-Louise Reysenbach, Jeff Seewald, and Bill Seyfried and Kang Ding from the USA. Participants also come from China, Portugal, Russia, and The Netherlands. They will study the geochemistry, geology, microbiology, and biology of the Rainbow, Lucky Strike, Lost City, and Snake Pit vent sites.

FIX08 cruise at the East Pacific Rise

FIX08: An interdisciplinary and international collaboration to study autotrophic carbon fixation and fluid chemistry at 9ºN and 13ºN EPR

An international group of scientists representing five different countries, i.e., USA, Germany, France, Italy, and China, was recently on board R/V Atlantis on cruise AT15-28, named FIX08. They were conducting work on in-situ chemistry of high- and low temperature hydrothermal vent fluids and the characterization of microbial communities carrying out autotrophic carbon fixation.
