Objective: Thirty years after the discovery of deep-sea hydrothermal vents, it is estimated that less than 10% of the global ridge crest has been mapped in detail or investigated systematically for hydrothermal venting. With the advent of routinely available AUV technology in a number of the world’s leading marine scientific institutions, we believe it is timely to propose placing hydrothermal exploration and the associated mapping of the ridge axis, on a new quantitative, regional- to global-scale footing. The plan for this WG is to identify vehicles with the necessary reliability, depth and endurance capability for long-range exploration of the mid-ocean ridge, define standard sensor packages and standardise calibration and data processing, develop a cruise plan, and identify the most urgent targets for such exploration work.

Long-Range Ridge Exploration
Working Group Update 2008
Chair - C. Devey (IFM-GEOMAR, Germany)
The WG for Long-Range Ridge Exploration was formed in 2008 and currently includes members from 8 countries (Brazil, China, France, Germany, Japan, South Africa, UK, and USA). The plan for this WG is to identify vehicles with the necessary reliability, depth and endurance capability for long-range exploration of the mid-ocean ridge, define standard sensor packages and standardise calibration and data processing,
