Benjamin Grupe

Benjamin Grupe

PhD student - Scripps Institution of Oceanography

Ben Grupe is a second year PhD student in the biological oceanography program at the Scripps Institution of Oceanography. He is interested in gastropods (limpets and snails) and other epifauna that live on hard substrates at Chiléan seeps and vents. During the INSPIRE: Chile 2010 cruise, he plans to investigate how diet is related to the physical environment by analyzing the stable isotopes and fatty acids of individuals in different habitats and on various substrata (such as, rocks, shells, and wood). Grupe also plans to use population genetics to determine whether the gastropods we discover at Chiléan seeps and vents are related to species found in other parts of the Pacific Ocean, such as Costa Rica or Oregon. Molecular markers can help us answer whether there is population connectivity or gene flow between similar habitats separated by thousands of kilometers. Grupe hopes to use trace elemental fingerprinting to analyze the larval shells of juvenile gastropods, thus providing insight into basic questions about the larval ecology of seep and vent fauna.

Rosa Leon-Zayas

Rosa Leon-Zayas

PhD student - Scripps Institution of Oceanography

Rosa León-Zayas is a third year PhD student in the Scripps Institution of Oceanography marine biology research division, working under the guidance of Dr. Douglas Bartlett. She is interested in deep-sea microbial communities, which experience extreme conditions of low temperature, high pressure, absence of sunlight, and more recalcitrant sources of organic nutrients. By using "creative culturing" approaches she attempts to culture novel piezophiles (high pressure-requiring microbes), which have been suggested from culture-independent studies to be important members of certain deep-sea microbial communities. Her study is focused in the Puerto Rico Trench and she is now venturing into the Peru-Chile Trench. The final goal is to obtain more information about the metabolic interactions and physiological processes happening in the deepest parts of our planet. During the INSPIRE: Chile Margin 2010 cruise, her sampling efforts will be concentrated on acquiring hadal water and sediment samples from the Peru-Chile Trench to assess the diversity and properties of the microbial community. León-Zayas believes that teaching science as an ever-changing field is crucial for the understanding of the nature of science by future generations, as they will influence the conservation of our natural resources.

Danny Richter

Danny Richter

PhD student - Scripps Institution of Oceanography

Danny Richter is a fifth year PhD student at the Scripps Institution of Oceanography. His research interests focus on the interaction between trace metals and diatoms, especially what metals are incorporated into diatom shells (called frustules). The potential implications of his research fuel his interest and they include: better understanding the biogeochemical cycling of these metals (many of which are essential for life but can also be lethal contaminants) and the possibility that frustule-bound metals in ocean sediments might be used to reconstruct oceanic nutrient distributions in the geologic past. Richter's work on the cruise will be a real-world test for the lab work of his PhD thesis. He will compare lab and real-world metal data from frustules and water to see if they tell the same story. This trip to Chile will be the seventh and final continent that Richter has visited in the name of science. He is also passionate about fixing climate change, and has had 22 meetings with members of congress or their staff to do just that.

In this expedition, his objective is to perform population sampling in the three stations for two or three recurrent species in reducing environments to evaluate parameters — such as genetic diversity, population connectivity, genetic differentiation, etc. Moreover, he expects to get DNA samples of most collected species on the cruise to perform phylogenetic and taxonomic analyses.

Timothy Shank

Timothy Shank

Associate Scientist, Biology Department, Woods Hole Oceanographic Institution

Tim Shank earned bachelor’s degrees in biology and German from the University of North Carolina at Chapel Hill. After college, he worked at the U.S. Environmental Protection Agency and then went on to receive a doctorate in ecology and evolution from Rutgers University, where he examined the evolution of deep-sea hydrothermal vent communities and the genetic relationships of vent fauna and their adaptations to thrive in extreme chemosynthetic environments. His research interests focus on understanding the evolution of life in the deep sea and the ecological processes responsible for creating and maintaining biodiversity in the oceans. Shank combines molecular genetic approaches and ecological field studies to understand the conditions and adaptations that allow various species to migrate, evolve, and thrive along the global mid-ocean ridge and seamount systems. He has conducted more than 35 scientific expeditions to deep-sea hydrothermal vents, hydrocarbon seeps, and continental slopes. He uses submersibles, remotely operated vehicles (ROVs), and autonomous underwater vehicle; and he recently tested a full-ocean depth hybrid ROV capable of diving to the deepest regions of the oceans.

Jordan Stanway

Jordan Stanway

Graduate student - Massachusetts Institute of Technology/Woods Hole Oceanographic Institution, Joint Program in Oceanography

Jordan Stanway is an applied ocean science and engineering graduate student in the deep submergence laboratory. He will be working with the autonomous benthic explorer (ABE) to collect navigation data from the vehicle while it searches for vents and maps the seafloor. Underwater vehicle navigation remains a difficult problem because signals from the Global Positioning System (GPS) do not penetrate the sea surface. ABE must instead rely on information from an internal compass and a Doppler velocity log (DVL) for dead reckoning, and occasional updates from an acoustic tracking system to keep the errors bounded. Stanway is working on sensor fusion techniques that promise to make the navigation estimate more robust and precise, especially when ABE is too high for the DVL to see the seafloor. (It is almost as important to know where ABE is when it collects scientific data as it is to collect the data in the first place.)

Christina Tanner

Christina Tanner

PhD student - Scripps Institution of Oceanography

Christina Tanner is a third year PhD student at Scripps Institution of Oceanography. On this cruise she aims to identify whether there are vesicomyid and solemyid bivalve species that inhabit both vent and seep sediments, characterize reproductive traits of the recovered adult bivalves, and use geochemical signatures in the shells of post-settlement juveniles to identify in which of the distinct, stratified water masses that occur over the Chile margin the larval stage develops. This work off Chile will provide insight into larval biology and dispersal pathways of deep-sea bivalves associated with seeps and vents. In order to do this, Tanner will rely on bottom trawls and the multicorer for the collection of adult and juvenile bivalve specimens, and conductivity, temperature, depth (CTD) and rosette water sampling to characterize overlying water masses.

Andrew Thurber

Andrew Thurber

Expedition Principal Investigator, PhD student - Scripps Institution of Oceanography

Andrew Thurber is a fifth year PhD student in the biological oceanography program at Scripps Institution of Oceanography. His research focuses on the interaction of animals (mostly worms), Bacteria and Archaea, and chemical cycling within mud at deep-sea methane seeps. In these systems, microorganisms consume greenhouse gases and harness chemical energy to exist with no direct input of energy from the sun. These microorganisms, in turn, provide a food source for many animals which are adapted to survive in these harsh environments. Thurber examines which of these chemical processes, as mediated by microbial metabolisms, both fuel and are impacted by the predation/ consumption by the animals which live there. On the INSPIRE: Chile Margin 20101 expedition, Thurber will serve as chief scientist; he will be examining which chemical reactions feed the animals present, if that changes at each of the sites he visits, and what are the ramifications of this varying food source for deep-sea biodiversity.
