Dr. Douglas H. Bartlett
Dr. Douglas H. Bartlett received his Ph.D. in microbial molecular biology at the University of Illinois in 1985. After several years as a postdoctoral scholar and Research Scientist at the Agouron Institute in La Jolla he assumed a faculty position at Scripps Institution of Oceanography, University of California, San Diego, in 1989, where he now holds the rank of Professor.

Dr. Bartlett has extensive experience in analyses of extremophilic microbial life in the inner space of our oceans. His research group pursues studies of the adaptations that enable deep-sea microbes to live at great pressures, up to and beyond 17,000 pounds per square inch. Much of this work utilizes the tools of genetics, genomics and functional genomics to work through the gene parts lists and wiring diagrams associated with particular aspects of microbial adaptation.

Current projects in the Bartlett laboratory include the directed evolution of microorganisms to greater tolerance to high pressure, comparative analyses among microbial populations in different trench systems, examination of pressure effects on deep-sea oil-degrading microbes, and single-cell and metagenome analyses of microbes from the deepest regions of the Atlantic and Pacific. In recent years he has spent considerable time at sea, often using autonomous sampling instruments to recover deep-sea samples. Future generations of these instruments will enable greater capabilities for exploration and sample recovery.

Dr. Patrick Heimbach
Dr. Patrick Heimbach is associate professor at the University of Texas at Austin and fellow of the W. A. “Tex” Moncrief, Jr.,chair III in Simulation-Based Engineering and Sciences. He is also visiting associate professor at the Massachusetts Institute of Technology. His research focuses on understanding the general circulation of the ocean and its role in the global climate system. As part of the “Estimating the Circulation and Climate of the Ocean" (ECCO) consortium, he and his group are applying formal inverse modeling techniques to produce a best possible estimate of the time-evolving three-dimensional state over the past few decades of the global ocean and sea ice cover. ECCO products support global and regional ocean circulation and climate variability research. Emerging research foci are understanding the dynamics of global and regional sea level change, the ocean’s role in the Earth’s energy imbalance, the provision of formal uncertainties along with these estimates, and implications for improving the global ocean observing system for climate. Patrick is also getting involved in investigating the polar ice sheets, their dynamics, their interaction with the ocean, and their contributions to sea level rise. He is a member of the National Academies’ Ocean Studies Board and the NASEM Committee on “Sustaining Ocean Observations to Understand Future Changes in Earth’s Climate”. Patrick is co-chair of the Deep Ocean Observing Strategy (DOOS) project and co-founder of the Advanced Climate Dynamics Courses (ACDC).

Dr. Brice Loose
Dr. Brice Loose is a geochemist and Associate Professor of Oceanography at the University of Rhode Island. He studies processes at the boundary between biogeochemistry and physical oceanography, with a strong focus on the polar oceans. One of his principal goal is to figure out how sea ice affects the polar ocean carbon cycle and how changes in sea ice will alter ocean storage of carbon dioxide and methane. This effort suffers from significant knowledge gaps surrounding the physics of air-sea exchange amongst mixed ice cover, as well as the microbiology that controls water column cycling of C1 compounds like methane. He is working to further develop ocean instrumentation for biogeochemistry. He teaches a course on prototyping, design and programming using IoT hardware and software, and he is developing optimized algorithms for processing data from underwater mass spectrometers.
