Jim Gaherty – Chief Scientist, LDEO Columbia University
Jim is a Lamont Research Professor at the Lamont-Doherty Earth Observatory of Columbia University, and is a co-Investigator on the PacificORCA project. His research focuses on using seismic imaging to probe the dynamics of Earth’s upper mantle, with particular emphasis on direct constraints on deformation processes and mantle flow. He takes Lamont’s long tradition as an “Observatory” to heart, leading seismic field expeditions to explore remote reaches of the earth such as the Canadian Arctic, islands offshore Papua New Guinea, rift-valley lake-bottoms in East Africa, and the depths of the central Pacific. He has taken a proactive role in the development and expansion of broadband seismology in the oceans, including the new international collaboration PacificArray. Email: firstname.lastname@example.org
Zach Eilon – Co-chief Scientist, UC Santa Barbara – @eilonzach
Zach is an Assistant Professor of Earth Science at the University of California Santa Barbara and a PI on the PacificORCA project. Zach’s research involves using seismic signals to investigate dynamic Earth processes using a variety of imaging techniques (i.e., making 3-D pictures of properties within the Earth). Having mostly focused his research on the continents, and how they break up or remain stable over billions of years, Zach is thrilled to finally have the chance go to sea and to dive into marine geophysical problems. While aboard, Zach has perfected his morning granola routine, drunk about a hundred gallons of coffee, and learned to identify 40 constellations. Email: email@example.com
Caroline Eakin – Faculty, Australian National University – @SeismoCaro
Caroline is a seismologist down under at the Australian National University (ANU), based within the Research School of Earth Sciences. Her work relates to imaging of plate tectonic processes and upper mantle dynamics inside the Earth. Having recently received an ANU Futures Scheme award to develop ocean bottom seismology in Australia, Caroline is here to gain experience in OBS deployments and build collaboration with the international community. As an international partner of the Pacific Array, seismologists in Australia hope to increase the number of seismic observations in the southern hemisphere and surrounding oceans to reach a better understanding of our planet. For Caroline’s musings on the humungous aquatic, see here.
Emily Hopper – Post-doc, LDEO Columbia University
Emily Hopper is a postdoctoral researcher working with Jim Gaherty at Lamont-Doherty Earth Observatory. She uses body waves to image structures in the tectonic plates, and enjoys speculating about what these could mean for the tectonic history of an area and current conditions in the upper mantle. She has been gradually transitioning to using ocean bottom data from land data, and is excited to be out here learning how we can get any of these very unique data. She is also still really excited about flying fish.
Karen Godfrey – PhD candidate, Brown University – @kgodfrey09
Karen’s research involves using seismic signals generated by earthquakes to image Earth’s upper mantle beneath the oceans. She has been using data collected by seismic stations located on the land surrounding the oceans, but ocean bottom seismometers provide an opportunity to study these regions at higher resolution. While at sea, she is learning more about these instruments and has also come to appreciate the enormity of the Pacific Ocean.
William Hawley – PhD candidate, UC Berkeley – @wbythewood
William Hawley is a graduate student at the Berkeley Seismological Laboratory and the Earth and Planetary Science department at the University of California, Berkeley. His research has focused on combining seismic observations from instruments on land and on the ocean floor to better understand how the movement of tectonic plates affects flow in the mantle, and vice versa. While aboard the Kilo Moana, he has enjoyed the food (but missed cooking), enjoyed the stars (but missed getting enough sleep), and vehemently defended the merits of cheese grits to skeptical scientists.

Rachel Hatch – PhD candidate, U. Nevada Reno – @rhatch_11
Rachel studies Geophysics at the University of Nevada, Reno. Her research focuses on characterization of sequences and swarms in the Walker Lane tectonic region in hopes of improving seismic hazard estimates. She specializes in earthquake relocation and studying source properties of moderate-to-small magnitude events. While at sea, she has enjoyed the food (a little too much), the stars, filming the deployments, and the vastness and beautiful blue color of the Pacific Ocean. Email: email@example.com
Josh Russell – PhD candidate, LDEO Columbia University – @JBRussell_
Josh is a seismology graduate student in the Department of Earth and Environmental Sciences at Columbia University. His PhD work makes use of seismic datasets collected from the seafloor (like PacificORCA) to improve our understanding of the dynamic processes behind the manufacturing and modification of Earth’s oceanic plates and the underlying mantle. In his spare time at sea, he has identified six species of pelagic birds and rescued one (a Wedge-tailed Shearwater) from the wrath of the OBS staging bay. Email: firstname.lastname@example.org
Stephen Mosher – PhD student, U. Ottawa
Stephen is a second-year PhD student at the University of Ottawa, Canada. His current research focuses on using techniques from machine learning to automatically detect, classify, and locate sources of seismic energy, especially those recorded by ocean-bottom instruments. His favourite parts of the voyage have been star gazing, being mesmerized by ocean waves, and meeting a fantastic group of people. Email: email@example.com
Carlos Gomez – Masters student, Cal State Northridge
Carlos Daniel Gómezis a 1styear Masters student at the California State University Northridge, and official t-shirt artist for the PacificORCA project. His graduate research focuses on using the Finite Element Method to study the tectonic evolution of the Southern California /San Andreas Fault region. His undergraduate research has taken him to the Arizona desert to study the volcanics associated with the Laramide Orogeny, the Igneous Bushveld Complex in South Africa where he learned various near-surface geophysical techniques and the ALBACORE array off the shore of Southern California, where he used novel anisotropy techniques to study the Lithosphere-Asthenosphere boundary.
Yuki Kawano – Masters student, ERI U. Tokyo
Yuki is a second-year master student at the Earthquake Research Institute of the University of Tokyo, and she will begin working on her PhD next year. Currently, she is working on tilt and compliance noise reduction from vertical component seismograms recorded by BroadBand Ocean Bottom Seismometers (BBOBS), and she is going to investigate upper mantle seismic structure under the Ontong-Java Plateau. On this cruise, she learned a lot about American BBOBS and amazed by the sophisticated system of OBS. Email: firstname.lastname@example.org
Jumpei Maruyama – Masters student, ERI U. Tokyo
Jumpei is a masters student in the Earthquake Research Institute of the University of Tokyo, working with Prof. Hitoshi Kawakatsu. His research focuses on upper mantle structure, especially on radial anisotropy in the lithosphere and asthenosphere, using various seismic data including signals recorded using OBSs. During the cruise, Jumpei has overcome seasickness, devoted himself to rejecting (data!) outliers, and learned some English words for international communication. Email: email@example.com
