R/V Atlantis OASES cruise to Mid-Cayman Rise

Posted 一月 25th, 2012 by Coordinator

Beginning January 6, 2012, an international, interdisciplinary team of scientists will be spending nearly a month at sea aboard the R/V Atlantis and using the deep-diving, remotely operated vehicle (ROV) Jason to explore and sample newly discovered hydrothermal fields (the Beebe vent site at 5000 m and Von Damm vent site at 2600m on the Mid-Cayman Rise—Earth’s deepest and one of its most slowly-spreading mid-ocean ridges. On board is one of InterRidge's 2011 Fellows - Dr Eoghan Reeves.

SO-216, Manus Basin, June 2011

Posted 一月 3rd, 2012 by Coordinator

Between June 14 and July 23 of 2011 a science team lead by Wolfgang Bach of the MARUM research center in Bremen used the German research vessel SONNE for hydrothermal studies in the Manus Basin, Papua New Guinea. During the transits and in the Manus Basin, bathymetric maps of the seafloor were produced. In the study area, the ROV MARUM-QUEST was used to map and sample hydrothermal vent systems in water depths between 1150 and 1800 meters below sealevel. Quest can document venting with HD photos and videos and take samples of rocks, fauna, and fluids.

IODP Expedition 335 Superfast Spreading Rate Crust 4

Posted 十一月 21st, 2011 by Coordinator

The Superfast campaign, echoing long standing ocean lithosphere community endeavors, was designed to understand the formation, architecture and evolution of ocean crust formed at fast spreading rates. IODP Expedition 335 "Superfast Spreading Rate Crust 4" (13 April to 3 June 2011) was the fourth scientific drilling cruise of the Superfast campaign to ODP Hole 1256D. The cruise aimed to deepen this basement reference site several hundred meters into the gabbroic rocks of intact lower oceanic crust.
