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.

Australian cruise SS07-2008 in the northern Lau Back-arc Basin
The InterRidge Office would like to highlight an Australian research cruise currently underway in the northern Lau Back-arc Basin (NLB). The SS07-2008 cruise, led by Chief Scientist Richard Arculus from Australian National University, will be in two legs from 30 April - 7 June 2008 on R/V Southern Surveyor. The objective of the first leg will be to survey the bathymetry, magnetic characteristics, petrology, hydrothermal activity, and hence origins and evolution of two of four spreading centers within this region (Northwest Lau [NWLSC] and Niuafo’ou [NSC]), which are essentially unstudied.
