A strategy for the conservation of biodiversity on mid-ocean ridges from deep-sea mining.

Abstract

Mineral exploitation has spread from land to shallow coastal waters and is now planned for the offshore, deep seabed. Large seafloor areas are being approved for exploration for seafloor mineral deposits, creating an urgent need for regional environmental management plans. Networks of areas where mining and mining impacts are prohibited are key elements of these plans. We adapt marine reserve design principles to the distinctive biophysical environment of mid-ocean ridges, offer a framework for design and evaluation of these networks to support conservation of benthic ecosystems on mid-ocean ridges, and introduce projected climate-induced changes in the deep sea to the evaluation of reserve design. We enumerate a suite of metrics to measure network performance against conservation targets and network design criteria promulgated by the Convention on Biological Diversity. We apply these metrics to network scenarios on the northern and equatorial Mid-Atlantic Ridge, where contractors are exploring for seafloor massive sulfide (SMS) deposits. A latitudinally distributed network of areas performs well at (i) capturing ecologically important areas and 30 to 50% of the spreading ridge areas, (ii) replicating representative areas, (iii) maintaining along-ridge population connectivity, and (iv) protecting areas potentially less affected by climate-related changes. Critically, the network design is adaptive, allowing for refinement based on new knowledge and the location of mining sites, provided that design principles and conservation targets are maintained. This framework can be applied along the global mid-ocean ridge system as a precautionary measure to protect biodiversity and ecosystem function from impacts of SMS mining.

Dr. Cindy Lee Van Dover is a deep-sea biologist with an interest in ocean exploration and the ecology of chemosynthetic ecosystems. She began her work in this field in 1982, joining the first biological expedition to hydrothermal vents on the East Pacific Rise. After earning a Master's degree in ecology from UCLA in 1985, she continued her graduate education in the MIT/Woods Hole Oceanographic Institution Joint Program in Biological Oceanography. There she joined numerous expeditions and published on diverse topics such as reproductive strategies and recruitment of vent invertebrates, vent food webs, and taxonomic descriptions of new species. In 1989, she described a novel photoreceptor in a vent invertebrate, which in turn led to discovery and characterization of a geothermal source of light at vents and investigations of its biological significance. On receiving her Ph.D. in 1989, Van Dover joined the group that operates the deep-diving submersible ALVIN. She qualified as pilot in 1990 and was pilot-in-command of 48 dives. Her work with ALVIN and other deep-submergence assets has taken her to nearly all of the known vent fields in the Atlantic and Pacific, as well as to deep-water seamounts, seeps, and other significant seafloor features. Her current research focuses primarily on the study of biodiversity, biogeography, and connectivity of invertebrates from chemosynthetic ecosystems and invertebrate functional anatomy.  in addition, she is active in developing pre-industrialization policy and management strategies for deep-sea resources. She has published more than 80 articles in peer-reviewed journals and is an active participant and Chief Scientist in NSF-and NOAA-sponsored field programs to deep-sea environments. 
In addition to research, Van Dover has authored a popular book for the lay audience about the deep sea and her experiences as an ALVIN pilot (Deep-Ocean Journeys; Addison-Wesley, 1997, a.k.a. The Octopus's Garden). She is also the author of the first textbook on hydrothermal vents (The Ecology of Deep-Sea Hydrothermal Vents; Princeton University Press, 2000). Van Dover is curator of Beyond the Edge of the Sea, a traveling exhibition of illustrations of deep-sea organisms and environments by artist Karen Jacobsen (http://oceanography.ml.duke.edu/discovery/) and is currently project lead for Science and Art at the Moment of Discovery, hosting 6 artists (water color, acrylic, experimental media, batik) on a deep-sea research expedition in June 2012.  Her work has been featured in Science News, Discover Magazine, The New York Times, and National Public Radio. Dr. Van Dover was named Virginia Outstanding Scientist in 2006 and is a Fulbright Scholar (France 2004), Fellow of the American Association for the Advancement of Science, and Distinguished Lecturer for the NSF Ridge 2000 Program. She is the inaugural recipient of the Mines Medal for exceptional leadership and innovation, a George Hammell Cook Distinguished Alumni Award (Cook College, Rutgers University), a Career Awardee from the National Science Foundation, and a William & Mary Alumni Fellowship Awardee for Outstanding Teaching. She is currently the Harvey W Smith Distinguished Professor of Biological Oceanography at Duke University, Chair of the Division of Marine Science and Conservation, and Director of the Duke University Marine Laboratory in Beaufort, N.C.
