Senior Scientist, MBARI
Dave's research interests are nearly all related to the formation and degradation of oceanic volcanoes, particularly Hawaiian volcanoes, mid-ocean ridges, and isolated seamounts. Topics of interest include: compositions of mantle sources for basaltic magmas and conditions of melting; volatile and rare-gas components in basaltic magmas and their degassing history; chronostratigraphic studies of eruption sequence and evolution of lava chemistry during volcano growth; subsidence of ocean volcanoes and its related crustal flexure, plate deformation, and magmatic activity; geologic setting of hydrothermal activity; origin of isolated seamounts; and monitoring of magmatic, tectonic, and hydrothermal activity at submarine and subaerial volcanoes.
Senior Research Technician, MBARI
Jenny works with Dave Clague in the Submarine Volcanism project. On this expedition, Jenny will be in charge of the GIS work, including use of the recently acquired, high-resolution MBARI mapping AUV data of our dive site. She will also stand watch in the ROV control room, help with rock and sediment sample workup and curation once the vehicle is on deck, and coordinate these cruise logs. She is now quite solidly a marine geologist, but her degrees are in biochemistry (Smith College) and biological oceanography (Oregon State University). She is thankful for the opportunities that have led her to study volcanoes, and loves being involved with the research and going to sea. She looks forward to discovering more about how the Earth works.
Biologist, Video Lab Technician, MBARI
Lonny received a B.S. in Marine & Coastal Ecology from California State University, Monterey Bay, and an M.S. from Moss Landing Marine Laboratories. His thesis work at MLML described the biological communities found at three seamounts off the coast of California. On this cruise, Lonny will be in charge of biological sample collection and processing and video data management. This work entails identifying unique biological and geological features that will be seen during the dive, while using MBARI-designed software to log the observations. He will also be preserving and organizing many of the biological samples collected during the cruise, preparing them for identification and further analysis by MBARI scientists and research collaborators.
National Evolutionary Synthesis Center
Craig has conducted deep-sea research for 11 years and published over 30 papers in the area. Participation in dozens of expeditions has taken him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig's research focuses on the ecological and evolutionary drivers of marine invertebrate biodiversity and body size. He is the author and editor of Deep-Sea News, a popular deep-sea themed blog and rated as the number one ocean blog on the web, and his writing has been featured in Cosmos, Science Illustrated, and Open Lab: The Best Science Writing on the Web.
John studies large caldera-forming volcanoes and their eruptions—termed supervolcanoes and super-eruptions by the popular media—which have global impact. The underlying causes of these large eruptions remain enigmatic. John also studies volcano degassing, which can result in severe local, regional, and global impacts. Understanding the subterranean pathways through which volcanic gas is transported allows insight into the subsurface structure of volcanoes, and can also aid in eruption forecasting and better understanding magmatic-hydrothermal ore deposits. John's interest in this cruise lies in better understanding caldera development in marine environments in relation to underlying magmatic processes. John has been chair of the McGill Earth and Planetary Sciences Department from 2006 to 2010 and executive editor of the Bulletin of Volcanology from 2003 to 2010.
Summer Intern, MBARI
Currently Isobel is an MBARI summer intern working with the Submarine Volcanism Group looking at how crust is built at intermediate-spreading mid-ocean ridges and how melts are supplied to seafloor eruptions. Isobel is also a second year Ph.D. student at Durham University in the U.K. At home she uses physical volcanology and geochemistry to study how huge volcanic edifices (called Axial Volcanic Ridges) are being built on the Mid-Atlantic Ridge. This will be Isobel's second research cruise and she can't wait to go to sea again!
Postdoctoral Fellow, MBARI
Ryan recently completed his Ph.D. at Macquarie University in Sydney, Australia, working on volcaniclastic and sedimentary rocks of the Macquarie Island ophiolite. His interests mainly focus on subaqueous mass gravity flows and their relationships to tectonic and volcanic controls. By identifying these relationships and implementing provenance and geochemical techniques, insight into the petrogenetic history of igneous and metamorphic source terrains is sought out. Soon to start a postdoctoral fellowship at MBARI, Ryan will examine the modes of volcaniclastic particle transport and dispersal from deep-sea eruptions, and their record of eruptive and magmatic controls.
University of Quebec, Chicoutimi
Lucas Brião Koth finished his bachelor's degree in geology at the University of Brasília, Brazil, in 2008 and currently is working toward his master's degree at the University of Quebec, Chicoutimi. His research is focused on the relationship between dykes, synvolcanic faults, and mineralization associated with an Archean subaqueous volcanic center. His participation in this cruise will be complementary to his studies and is also a great opportunity to look at modern submarine volcanism and better understand the genesis of volcanic massive sulfide deposits (VMS) associated with these geological environments.
Assistant Professor of Marine Biology
University of Alaska
Sarah has a B.A. in marine biology from University of California, Santa Cruz, an M.S. from San Francisco State University, and a Ph.D. in biological oceanography from the University of Hawaii. Her research focuses on the biology and ecology of benthic invertebrates, particularly in polar and deep-sea environments. She is especially interested in the growth, reproduction and dispersal of benthic invertebrates, and uses a variety of research tools including genetic techniques. On this expedition, Sarah is working with Craig McClain to conduct biological investigations on the fauna encountered on seamounts. Their goal is to determine the number of invertebrate species found at various depths on seamounts, and investigate whether (and why) seamounts are home to unique and/or more diverse invertebrate communities than other seafloor habitats. Sarah will also be collecting specimens for use in genetic studies to look at patterns of gene flow on seamounts, which will provide clues to tell us whether seamount act like isloated island habitats, or whether tiny invertebrate larvae are able to move between seamounts and the mainland.
Graduate Student, McGill University
Jason graduated in 2010 with an H B.S. in geology from the University of Toronto and is a M.S. student at McGill University, Montreal. His research focus will be oriented on the geology and petrology of the Taney Seamounts. His research interests are the physical, chemical and geodynamic processes that govern volcanism.
Justine recently received her bachelor of science degree in biology from Duke University, where she worked for Craig McClain at the National Evolutionary Synthesis Center. She will be entering the marine biology graduate program at the University of California, Santa Cruz, in the fall with plans to pursue a career in marine conservation biology.
