Circum-Antarctic Ridges workshop, 2011, Toulouse, France

An initial workshop was convened in Toulouse in September 2011. Click here to read the report. 

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


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.

Oceanic Detachment Faults WG proposal

After the initial establishment of the Working Group (WG), membership to the WG will remain open to the international scientific community while the WG is active. New members interested in the WG theme will be expected to promote and contribute intellectually to the activities of the WG, and with ideas/suggestions that help carry on the mandate of the WG.

New InterRidge Working Groups

The InterRidge Office is pleased to announce new Working Groups:

Ocean Detachment Faults: Co-Chairs - J.Pablo Canales and Javier Escartin
Arc-Backarc Systems: Chair - Maria Seton
Seafloor Mineralisation - 3 year extension: Chair - Maurice Tivey
SMART - South Mid-Atlantic Ridge targeted Exploration: Chair: Colin Devey

WG proposal

Drivers of the Episodic life-cycle of Intra-oceanic Arc-Backarc Hydrothermal Systems 

Convergent margins, where oceanic lithosphere is subducted into the mantle, form the key interface for large–scale chemical and thermal recycling amongst the ocean, crust, mantle, and atmosphere. Intra-oceanic convergent margins typically produce a forearc-island arc-backarc sequence within an extensional stress regime and contain a disproportionate number of hydrothermal vents per unit area.
