Letter from the Director


Our July newsletter features new research by DCO scientists across the life, space, and Earth sciences.
 
In a paper in the Proceedings of the National Academy of Sciences, Jesse McNichol (University of Southern California, USA), Stefan Sievert (Woods Hole Oceanographic Institution, USA), Jeffrey Seewald (WHOI, USA), and colleagues estimate the global production of organic carbon by microbes living below the seafloor at deep-sea hot springs. Their data reveal a very active subseafloor biosphere that significantly influences global biogeochemical cycling.
 
Chris Glein (Southwest Research Institute, USA) and an international team of researchers published a paper in Nature reporting the discovery of complex carbon compounds emanating from the ice covered ocean on Saturn’s moon Enceladus. This finding suggests the moon's oceans contain the raw ingredients necessary for life.
 
Jodie Pall, Sabin Zahirovic, Sebastiano Doss, and Dietmar Müller (University of Sydney, Australia), and colleagues demonstrate that interactions between carbonate platforms and subduction zone volcanism have influenced the concentration of carbon dioxide in the atmosphere, as well as global climate, on geologic time scales during the past 410 million years.
 
DCO scientists have also been recognized this month. Congratulations to Tamsin Mather (University of Oxford, UK), who won the 2018 Royal Society Rosalind Franklin Award and Lecture, to Antje Boetius (Alfred Wegener Institute for Polar and Marine Research, Germany) who received the 2018 Communicators Award conferred by the Deutsche Forschungsgemeinschaft German Research Foundation and the Stifterverband, and to Claire Cousins (University of St Andrews, UK), who was elected to the Royal Society of Edinburgh Young Academy of Scotland.
 
We encourage you to submit abstracts to sessions of interest to the DCO community at the 2018 AGU Fall Meeting in Washington, DC, USA. The abstract deadline is 1 August 2018.
 
And lastly, more than 100 DCO scientists will present their research at Goldschmidt 2018 on 12–18 August 2018 in Boston, USA, including many session conveners and keynote speakers. We will report on this meeting next month.

What Lies Beneath: Microbes Thrive Below Seafloor Hot Springs
At deep-sea hot springs, the hot, chemical-rich fluids produced by geothermal processes in the ocean crust mix with cold seawater, providing conditions that support thriving communities of microbes. These organisms survive by chemosynthesis, converting the chemicals in the fluids into usable energy and biomass. They serve as the foundation of a strange ecosystem, including tubeworms, crustaceans, and octopuses, which flourishes in the darkness of the deep sea. Microbes live below the seafloor of the vents as well, but while scientists have investigated the identity of these subseafloor organisms, measuring their productivity has been far more challenging. In a new paper in Proceedings of the National Academy of Sciences, researchers have discovered that the microbes living below hydrothermal vents systems are surprisingly active. DCO Deep Life Community members Jesse McNichol (now at University of Southern California, USA), and Stefan Sievert (Woods Hole Oceanographic Institution (WHOI), USA) and Deep Energy Community member Jeffrey Seewald (WHOI, USA), along with colleagues at the Helmholtz Centre for Environmental Research (Germany), measured the activity levels of subsurface microbes while maintaining their local pressure and temperature conditions with specially designed gas-tight samplers. These experiments allowed them to make comprehensive measurements of microbial growth, identify dominant organisms, and estimate the global production of organic carbon by microbes living beneath deep-sea hot springs.

Saturn’s Moon Enceladus Harbors Complex Carbon Compounds Beneath its Icy Crust
Saturn’s moon Enceladus has a rocky core, surrounded by a global ocean encrusted by a sheet of ice. The moon may not look very hospitable, but data from NASA’s Cassini spacecraft suggest that Enceladus has all the raw ingredients necessary for life as we know it. Fly-bys of Enceladus previously revealed liquid water, hydrogen gas, and small carbon compounds, which together could potentially support microbial cells. Cassini’s mission ended in September 2017, when scientists sent it plummeting into Saturn, but researchers are still poring over the data it beamed back to Earth. A new analysis of those data finds that Enceladus not only has small organic molecules, but also larger, more complex carbon compounds bursting from its ocean. Chris Glein (Southwest Research Institute, USA), a member of DCO’s Deep Energy Community and Extreme Physics and Chemistry Community, and an international team of researchers report these findings in a new paper in the journal Nature.

Global Temperatures Rise When Ancient Reefs Encounter Subduction Zones
Carbonate platforms are ancient reefs that build up over millions of years, composed of the carbon-rich skeletons of coral and other tiny sea creatures. When these reefs get swallowed up by a subduction zone, where one tectonic plate sinks beneath another, the buried carbon can be remobilized and released to the atmosphere through volcanoes lining the subduction zone. A new study by DCO members Jodie Pall, Sabin Zahirovic, Sebastiano Doss, and Dietmar Müller (all at University of Sydney, Australia), and colleagues, finds that the remobilization of reef carbon through volcanoes can have a measurable impact on global climate. The researchers modeled the intersection of carbonate platforms and subduction zones during Earth’s history since the Devonian period, 410 million years ago. By comparing the total length of these intersections to estimates of historic atmospheric carbon dioxide levels, they could pick out periods when liberated reef carbon contributed to warmer temperatures, including during the Paleocene–Eocene Thermal Maximum, about 55 million years ago. They report their findings in a new paper in the journal Climate of the Past. Read more...

GeoPRISMS Program Solicitation
GeoPRISMS (Geodynamic Processes at Rifting and Subducting Margins) Program investigates the coupled geodynamics, earth surface processes, and climate interactions that build and modify continental margins over a wide range of timescales. These interactions cross the shoreline and have applications to margin evolution and dynamics, construction of stratigraphic architecture, accumulation of economic resources, and associated geologic hazards and environmental management. The GeoPRISMS Program includes two broadly integrated science initiatives (Subduction Cycles and Deformation (SCD) and Rift Initiation and Evolution (RIE)), linked by five overarching scientific topics and themes, where transformative advances are likely to occur in the decade 2011-2020, and where a focused scientific program could be most effective. These overarching science topics include 1) Origin and evolution of continental crust; 2) Fluids, magmas and their interactions; 3) Climate-surface-tectonics feedbacks; 4) Geochemical cycles; and 5) Plate boundary deformation and geodynamics. Each of the initiatives has identified primary sites for focused investigations, as well as thematic studies that will complement primary site studies. Full proposal deadline: 13 August 2018


Deep Life Cultivation Internship Program
DCO's Deep Life Community (DLC) realizes that the majority of deep microbial life has been resistant to cultivation in the laboratory, which complicates the characterization of physiological characteristics of deep community members. However, recent studies using bioreactor-cultivation techniques, under high pressure and/or temperature, have resulted in successful enrichment of previously uncultivable archaeal and bacterial components that mediate biogeochemical carbon cycling in the deep subsurface. To maintain and strengthen cultivation strategies in future deep life missions, the DLC will support early career researchers to visit some key laboratories (Inagaki - Kochi, Japan, Bartlett - La Jolla, USA, and others) to learn and practice newly developed cultivation and cultivation-dependent molecular/biogeochemical techniques, using samples from the DLC’s field missions.


C-DEBI: Rolling Call for Research Exchange Proposals
The Center for Dark Energy Biosphere Investigations (C-DEBI) facilitates scientific coordination and collaborations by supporting student, postdoctoral, and faculty exchanges to build, educate, and train the deep subseafloor biosphere community. We award small research exchange grants for Center participants. These grants may be used to support research, travel for presenting C-DEBI research at meetings, or travel exchanges to other partner institutions or institutions that have new tools and techniques that can be applied to C-DEBI research. We anticipate ~10 awards of $500-5,000 with additional matched funds to be granted annually.
