2012 Update

Deep-sea Mining
The pilot Solwara 1 project could start operations in 2012. The vent biology community is closely watching this world-first and worries about the consequences. Helen Rosenbaum wrote a very nice and comprehensive report on the subject, including economics and biology. This report can be downloaded from Another article more generally about mining the ocean floor in the Pacific can be aceessed at:

2012 Update

The Seafloor Mineralization Working Group was renewed for a second term at the last InterRidge Steering Committee meeting in San Francisco in December 2011. Interest in the mineralisation resources at midocean ridges has continued unabated with the price of metals such as copper, gold and silver near historic highs and nations beginning to look at options for exploration of seafloor areas for polymetallic sulfide resources in “the area” under the regulations of the International Seabed Authority (ISA).

2012 Update

The InterRidge Oceanic Detachments WG was put in place in January 2012, following the results and recommendations of the 2010 AGU Chapman Conference on “Detachments in the Oceanic Lithosphere”: (ht

2012 Update

Hangzhou meeting
The second WG group meeting was held in Hangzhou, China on 10-11 October 2011. It was hosted by the 2nd Institute of Oceanography. Xiqiu Han, also a member of the WG, has been a greatly appreciated local organiser. The visit included additional exchanges with colleagues and seminars for students for several meeting attendees. The group of attendees involved L. Bharathi (India), T. Gamo (Japan), C. German (US), G. W. Luther (US), X. Han (China), N. Le Bris (France), L. Legendre (France), S. Sander (NZ) and S. Sievert (US).

2012 Update

• An initial working group planning meeting is scheduled during the International Geological Congress (IGC) Meeting in Brisbane (6-10 August, 2012)
 Members are involved in convening themes/symposia at the IGC 2012:
o Theme: Mineral Deposits and Ore Forming Processes (Large, de Ronde)
o Symposium: Volcanic and basin-hosted ores (Fe, Zn-Pb, Cu, U) (Gemmell, de Ronde, Bull, Leach) 
o Symposium: Marine minerals in Oceania (Cronan, de Ronde, Exon)

Proposal for Circum-Antarctic Ridges (CAR) Working Group, 2012

Although Circum-Antarctic Ridges (CAR) represent over one third of the global mid- ocean ridge system, they remain the least known sections of mid-ocean ridges, mostly because of their location in high latitudes and areas of rough seas. However, Circum-Antarctic Ridges are unique by their shallow water depths, ultra-slow or intermediate spreading rates, and complicated series of transform offsets compared to low-latitude ridges.

Third Decadal Plan - draft now open for comments

In 2011 InterRidge initiated a discussion online and at a meeting attached to AGU, to identify the major science questions it was felt InterRidge should address in the next decade. A draft of the Third Decadal Plan 2014-23 is now available for consultation by the InterRidge community.
