Welcome Bulgaria, new InterRidge Corresponding Member

We would like to welcome Bulgaria as a new Corresponding Member of InterRidge, with Dr. Vesselin Dekov serving as Bulgaria's first national correspondent. Dr. Dekov is an Associate Professor in the Department of Geology and Paleontology at the University of Sofia. With the addition of Bulgaria, we now have 31 Member Nations and Regions in InterRidge (http://www.interridge.org/nations). Look for the first update from Bulgaria in the next issue of InterRidge News later this year.

Inactive Hydrothermal Vent Field Discovered at the Southwest Indian Ridge 50.5ºE

The 5th leg of the 2008 Chinese DY115-20 expedition on board R/V Dayangyihao has successfully discovered an inactive hydrothermal vent field at 50.4671°E, 37.6579°S on the ultraslow-spreading Southwest Indian Ridge (SWIR). This inactive hydrothermal field is located on the shallowest portion of Segment 27 of the SWIR west of the Gallieni Transform Fault, with relative low mantle Bouguer gravity anomaly (Sauter, et al., 2001). This newly found site is located in the middle of a ridge segment, where the rift valley disappears and the seafloor depth is 1739 m.

First Active Hydrothermal Vent Fields Discovered at the Equatorial Southern East Pacific Rise

In August-September 2008, the third leg of the 2008 Chinese DY115-20 expedition on board R/V DayangYihao has successfully discovered, for the first time, active hydrothermal vent fields on the fast-spreading Southern East Pacific Rise (SEPR) near the equator. This expedition follows the work of a 2005 expedition by R/V DayangYihao, during which water column turbidity anomalies were measured in the region.

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.

In Memoriam: Dr. Hitoshi Sakai

Dr. Hitoshi Sakai 1930-2008
The InterRidge office has just received the sad news that Dr. Hitoshi Sakai, Professor Emeritus and world-renowned researcher in stable isotope geochemistry at Okayama University, passed away on Tuesday, September 30 after a protracted illness. He was 78 years old.

In Memoriam: Karen L. Von Damm

Karen L. Von Damm 1955-2008
The InterRidge community mourns the loss of Karen Von Damm, a full professor and world-renowned researcher in marine geochemistry at the University of New Hampshire, who passed away at her home in Durham, NH, on August 15, 2008, after being diagnosed with liver cancer in April, 2008. She was 53 years old.

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.
