InterRidge participates at KOPRI's 16th International Symposium on Polar Sciences

On June 10-11, the Korea Polar Research Institute (KOPRI) hosted the 16th International Symposium on Polar Sciences in Incheon, Korea. The symposium brought together ~144 scientists from the broad fields of both ridge and climate research, representing 11 countries around the globe. The meeting was timely, with the expected launch this week of the new Korean research icebreaker R/V Araon, with sea trials planned for November 2009.

2009 InterRidge Student and Postdoctoral Fellows

The InterRidge Steering Committee is very pleased to announce the awards for the 2009 InterRidge Student and Postdoctoral Fellowship Program. The awards go to Susan Lang, a postdoctoral researcher at Scripps Institution of Oceanography (SIO), USA, to work at a laboratory in Switzerland, and to Surya Prakash, a Ph.D. candidate at the National Institute of Oceanography (NIO), India, to conduct research in the USA.

BISMaL, a new biological database online at JAMSTEC's Global Oceanographic Data Center

JAMSTEC has just launched a new database, Biological Information System for Marine Life (BISMaL), online at the Global Oceanographic Data Center (GODAC):
http://www.godac.jp/portal/page/portal/GDC/GPSS216/TAB_TOP
You can search marine species including those from deep-sea vents and seeps around the Japan Islands and browse photographs, descriptions on morphology/ecology, videos, sample records, and references of each species.

Scientific questions and recommendations from the InterRidge Seafloor Mineralization Working Group

The InterRidge Working Group on Seafloor Mineralization (SMWG) has developed three groups of questions and recommendations to advance the scientific knowledge of seafloor massive sulfide (SMS) deposits:
What are the spatial controls on hydrothermal activity and SMS deposition?
What are the timescales for the evolution of SMS deposits?
What are the changes in biological communities that occur during the evolution of an SMS deposit?
Recommendations range from developing a list of criteria to quantify the extent of activity at a hydrothermal vent site, to using cutting‐edge technology to locate and characterize inactive deposits, to encouraging biological studies of inactive and extinct SMS deposits.

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.
