Circum-Antarctic Mid-Ocean Ridges: Structure, Evolution, Mantle Dynamics, Hydrothermal Activity and Ecological Communities

Submit an Abstract to this Session



Session ID#: 27220

Session Description:
The Circum-Antarctic mid-ocean Ridges (CAR) represent a window on mantle processes over three large interacting mantle domains (Atlantic, Indian, and Pacific). The hydrothermal activity along the CAR is also the source of major chemical transfers to the Southern Ocean, and it offers the ecological niche for deep-sea communities to develop and migrate. These ridges have been the focus of a number of recent cruises as a large coordinated effort from the InterRidge community. This session provides a forum to present the results of these investigations and enhance the collaborations. We welcome the latest results and insights from field programs and shore-based investigations, concerning mid-ocean ridge structure and dynamics, mantle composition, circulation and melting, ocean-crust chemical interaction and ecological communities, as well as comparative studies with global ocean ridges. We encourage students and early-career scientists to present their work, and hope to enhance multidisciplinary researches on these frontier topics.
