From 12-25 February 2017, a team of DCO Early Career Scientists conducted field work across the Costa Rica volcanic arc. At hot springs and volcanic sites around Costa Rica, the team collected gases, sediments, tephra, and water in the cross-disciplinary DCO Synthesis initiative, Biology Meets Subduction.

Letter from the Director
In a groundbreaking new paper, Edward Young (University of California Los Angeles, USA) and 23 co-authors from 14 institutions in 8 countries report the first resolved measurements of two rare forms of methane in gases collected from a wide range of geologic settings across the globe. These measurements provide unprecedented insights into the origins and evolution of methane, achieving one of DCO’s decadal goals.
DCO Summer School alumna Suzette Timmerman (Vrije Universiteit, Netherlands) is the lead author of a new paper using diamonds to trace the evolution of the deep carbon cycle beneath Botswana through 2 billion years of Earth history.
DCO field expeditions are making remarkable progress. Live From Costa Rica, Where “Biology Meets Subduction,” shares the excitement of a field expedition by 20 DCO Early Career Scientists to investigate the deep carbon cycle at the Costa Rica convergent margin from 12-25 February 2017.
The Oman Drilling Project recently recovered excellent core samples of the sheeted dike/gabbro transition and has begun rotary drilling in the mantle section of the ophiolite. The application process remains open to participate in Oman drilling and core logging activities.
We invite applications for the Third DCO Early Career Workshop to study Mt. Etna, Italy from 28 August-2 September 2017. As a reminder, DCO will be well represented at the Goldschmidt Conference in Paris and the abstract deadline is 1 April 2017. DCO continues to seek your input as it plans for the future.

Transformational Instrumentation Differentiates Abiotic vs. Biotic Methane
Mysteries associated with methane’s origins and evolution have intrigued the scientific community for decades. Hunting for elusive clues, scientific detectives focused their efforts on seeking reliable signatures of abiotic versus biotic sources of methane. Innovative technology for “fingerprinting” methane is enabling investigators to decipher complicated “crime” scenes at field sites around the world — revolutionizing our understanding of methane. The Deep Carbon Observatory helped launch a new era of high-tech sleuthing when Young et al. (2016) developed a new instrument, the Panorama mass spectrometer, to make the first resolved measurements of two rare forms of methane. These measurements can provide unprecedented insights into the origins and evolution of methane, achieving one of DCO’s decadal goals. In a groundbreaking new paper published in the journal Geochimica et Cosmochimica Acta, Edward Young (University of California Los Angles, USA) and 23 co-authors from 14 institutions in 8 countries unequivocally demonstrate Panorama’s proof of concept.

Prony Bay Chimneys Have Surprising First Inhabitants
At the bottom of Prony Bay by New Caledonia in the Pacific Ocean, lies a field of tall, rocky edifices called chimneys, which form from streams of warm, alkaline fluids that emerge from the seafloor. These chimneys, and the hydrothermal vent fluids that pour out of them, offer a window into the conditions existing in recesses in the rocks deep beneath the ocean floor, and into the microbes that survive there, in circumstances that could be close to the habitat that supported the first cells on Earth. DCO’s Céline Pisapia, Emmanuelle Gérard, and Bénédicte Ménez (all from the Institut de Physique du Globe de Paris, France) and colleagues, examined newly forming chimneys in Prony Bay to identify the first organisms that colonize them. In a new paper in Frontiers in Microbiology, they report the detection of filamentous bacteria, which serve as scaffolding for the chimneys, and likely live on organic compounds present in the vent fluids.

History of Earth's Early Carbon Cycle Recorded in 2-Billion-Year-Old Diamonds
For jewelry makers, imperfections in diamonds are flaws. But for geologists, these flaws hold valuable clues. Certain flaws, called mineral inclusions, reveal details such as how long the diamond took to form and the processes that shaped its growth. Members of DCO’s Reservoirs and Fluxes Community Gareth Davies, Suzette Timmerman, and Janne Koornneef (all from Vrije Universiteit, Amsterdam) investigated mineral inclusions within diamonds from Botswana. They identified one containing silicate material that formed 2.3 billion years ago in its interior and a 250-million-year-old garnet crystal towards its outer rim, the largest age range ever detected in a single specimen. Their analysis, published in a new paper in Earth and Planetary Science Letters, suggests that carbon exchange and deposition between the atmosphere, biosphere, oceans, and geosphere may have changed significantly over the past 2.5 billion years.

New Teaching Tool to Increase Understanding of Gas Hydrates and the Deep Biosphere
When Janelle Sikorski began teaching oceanography to a group of non-science majors at the Miami University in Oxford, Ohio, she realized that most of the students weren’t aware of the myriad ways that humans and the ocean interact, apart from issues of ocean pollution. Studies suggest that most college students share this lack of awareness of the Earth’s largest geologic feature. To help address this gap, Sikorski worked with Brandon Briggs, a member of DCO’s Deep Life Community, (both now at the University of Alaska Anchorage, USA), to develop a course module that teaches students about the formation and distribution of gas hydrates, which are stable, ice-like deposits of methane and water that form in seafloor sediments. They published their module in a recent paper in the Journal of Geoscience Education. Read more...
New Mineral Named in Honor of DCO co-Executive Director Hemley
Rus Hemley’s pioneering contribution to high-pressure science was recognized this month with a new mineral, hemleyite, named in his honor. Hemley’s colleagues, Luca Bindi, Ming Chen, and Xiande Xie, reported the discovery of the first natural occurrence of the Fe-analogue of akimotoite in Nature Scientific Reports on 15 February 2017. The International Mineralogical Association approved this new mineral and its new name, hemleyite, in honor of Dr. Russell J. Hemley. Hemley is the former director of the Geophysical Laboratory of the Carnegie Institution for Science, and now a research professor at George Washington University, in Washington, DC. Hemley has been instrumental in the work of the Deep Carbon Observatory, and serves as its co-executive director. Read more...

Loss of John Hayes, a Deep Carbon Pioneer
John Hayes, a geochemist and an esteemed member of the Deep Carbon Observatory’s Science Network, passed away at his home in Berkeley California on 3 February 2017. Hayes was a scientist emeritus at Woods Hole Oceanographic Institution and retired director of its National Ocean Sciences Accelerator Mass Spectrometry facility. “John was the leading pioneer of molecular-isotopic biogeochemistry and has been a great inspiration for so many younger scientists, including me. His passing will leave a huge gap in the geochemistry community. I will miss John very much - as scientific mentor and friend. I am very grateful for his guidance, generosity and warm friendship, and for sharing his unique approach to science,” said Kai-Uwe Hinrichs, University of Bremen, Germany, and co-chair of DCO’s Deep Life Community.
