Microbial Community Variability in Hydrothermal Vents Along the Mid-Cayman Rise
Hydrothermal vents on the seafloor play host to thriving ecosystems of diverse bacterial and archaeal species. Since studying microbes living within the rocky seafloor is challenging, researchers sample hydrothermal fluid seeping out of the seafloor as a window into subseafloor communities. The microbes at these sites thrive on energy sources such as hydrogen sulfide and methane derived from water-rock reactions, and are therefore directly linked to the chemistry and geology of the hydrothermal vent. In a recent publication, DCO’s Julie Huber (Marine Biological Laboratory, Woods Hole, USA), Jeffrey Seewald (Woods Hole Oceanographic Institution, USA), and Jill McDermott (University of Toronto, Canada) and colleagues provide a comprehensive examination of microbial life in the subseafloor at two newly discovered deep-sea hydrothermal systems at the world’s deepest spreading center in the Caribbean Sea, the mafic-hosted Piccard at 4960m and the ultramafic-influenced Von Damm at 2350m.

Volcanic Gas Precursors to Phreatic Eruptions at Poás Volcano, Costa Rica
Poás volcano (Costa Rica) is one of the most chemically extreme environments on Earth, hosting an ultra-acidic crater lake as well as high temperature fumaroles. The lake was the site of intense phreatic eruptive behavior between 2006 and 2014. Volcanic eruptions involving interaction with water are particularly energetic, causing a disproportionate number of human casualties. Phreatic eruptions are also exceedingly difficult to forecast, often occurring with little or no geophysical precursors. A new article published in Earth and Planetary Science Letters by a group of Deep Carbon Observatory scientists led by Maarten de Moor (Observatorio Vulcanológico y Sismológico de Costa Rica, Universidad Nacional, Heredia, Costa Rica) reports the results from a DECADE (Deep Earth Carbon Degassing initiative) project to investigate gas emissions at Poás. Read more...

Mineralogy and Microbiology at the Juan de Fuca Ridge
The largest aquifer on Earth lies within igneous oceanic crust. This deep environment plays host to microbial ecosystems, with diverse bacterial and archaeal communities living on energy produced when circulating seawater reacts with rocks and minerals. Earth’s crust is not homogeneous, however, and in a new paper in Geomicrobiology Journal, DCO’s Amy Smith, Rick Colwell (Oregon State University, USA), and colleagues investigate how variation in crust mineralogy affects the composition and abundance of deep microbial communities.

Film Featuring DCO Scientists at Lake Dziani Dzaha Part of EGU 2016 GeoCinema
A DCO sponsored film produced by Sur une île was selected for screening at the 2016 EGU General Assembly in Vienna, Austria. Lake Dziani Dzaha presents an unusual combination of characteristics making it a likely analog for some hydrocarbon-bearing lacustrine rocks of economic importance and possibly certain Precambrian environments, including expanding rift valleys and basins. A dense population of prokaryotes and cyanobacteria dominates the Dziani Dzaha ecosystem—giving it a permanently green color. Its waters are saline (twice ocean salinity), alkaline (pH = 9), extremely rich in dissolved inorganic carbon (100 times the amount in seawater), and anoxic below one-meter depth. It also precipitates microbialites, which are organo-sedimentary deposits that accrete as a result of a lake-bottom microbial community, forming the locus for mineral precipitation. View the documentary at EGU 2016 in room 0.90 at 2:00pm Tuesday, 19 April, 4:30pm Thursday, 21 April 2016, or on the DCO website here

New Updates from the Trail by Fire Expedition
23 March 2016: Home Sweet Villarrica! Driving to Villarrica felt like coming home. A few years back, several TBF members spent a month there studying the behavior of its lava lake. Back then, they faced a series of storms and found themselves working under the snow and digging out instruments from piles of ice every other morning.
7 March 2016: Nevados de Chillán: Nevados de Chillán was the team's first stop in the Southern Volcanic Zone (SVZ) after crossing the Pampean Gap, and they were all looking forward to getting back to work after such a long journey. Additionally, their clothes had almost lost the odor of sulphur, and they risked having their volcanologist membership cards revoked. Read more...

Funding Opportunities

DCO: Deep Life Cultivation Internship Program
The DCO Deep Life Community 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 deep subsurface. In order 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 Deep Life Community’s field missions. Financial support includes $5,400 per person for travel and lodging costs and host lab research supply reimbursement. Interested applicants should send their CV, a brief one page statement of their cultivation plans, and a letter of support from their intended host to inagaki [at] jamstec [dot] go [dot] jp (Fumio Inagaki) and dbartlett [at] ucsd [dot] edu (Douglas Bartlett).

Call for IODP Scientific Ocean Drilling Proposals
The International Ocean Discovery Program (IODP) explores Earth’s climate history, structure, dynamics, and deep biosphere. The D/V JOIDES Resolution plans to operate 10 months per year in 2018 and 2019 under a long-term, global circumnavigation track based on proposal pressure. Future JR expeditions are projected to follow a path from the southwestern Pacific Ocean, through the Southern Ocean, and into the Atlantic Ocean for opportunities starting there in 2019. The JR is then expected to operate in the Atlantic, Mediterranean, Caribbean, and Gulf of Mexico starting in 2020. Although JR proposals for any region are welcomed, pre- and full proposals for these future operational areas are strongly encouraged. MSP expeditions are planned to operate once per year on average, and proposals for any ocean are welcomed. Chikyu operations will be project-based, and new proposals to use Chikyu in riser mode must be Complementary Project Proposals (with cost-sharing). IODP aims to foster joint projects with the International Continental Drilling Program (ICDP). Therefore, IODP also invite proposals that coordinate drilling on land and at sea. Deadline: 1 April 2016

Call for Proposals: Census of Deep Life Sequencing Opportunities
Since 2011, the Deep Carbon Observatory’s Deep Life Community has sponsored the Census of Deep Life (CoDL) that has supported surveys of the diversity of microbes present in several deep continental and subseafloor environments. The first surveys (2011-2012) were conducted using 454 pyrosequencing and subsequently (2013) Illumina sequencing strategies were adopted. Through this initiative, the Deep Life Community has allowed the characterization of diversity of subsurface microbial communities at numerous sites worldwide including the subseafloor and deep continental locations from a range of geologic settings (e.g., large igneous provinces, subglacial lakes, methane hydrate-rich sediments, cratons). The Illumina platform provides increased numbers of reads for more samples at reduced cost. For DNA samples submitted to the CoDL for sequencing, proponents have the option of obtaining 400-450 nt bacterial sequences that span the V4V5 region of Bacterial and Archaeal rRNA coding regions or a greater number of reads for V6 regions that through complete overlap of forward and reverse reads allows detection of lower abundance taxa with reduced stochastic error rates. Shotgun metagenomic DNA sequencing for key samples can also be performed. This call for proposals aims to support sequencing that represents expanded analyses from ongoing Deep Life Community projects or projects that represent sites and investigators new to the DCO’s Deep Life Community. Deadline: 30 April 2016

DCO Diversity Grants
In January 2015, the Deep Carbon Observatory began collaborating with the American Geosciences Institute (AGI) to increase the participation and retention of United States citizens and permanent residents who are geoscientists from underrepresented groups (African American, Hispanic, Latino/Latina, Native American, Native Alaskan, Native Hawaiian, Filipino, and Pacific Islander) in DCO.

23 March 2016: What the Heck is a Diamond Anvil Cell?
Daniel Hummer for the DCOECS15 Blog
In the Extreme Physics and Chemistry (EPC) community, our main goal is to learn about the structure, properties, and behavior of carbon-bearing materials at the extreme temperature and pressure conditions in the interior of Earth and other planetary bodies. Scientists have performed experiments at elevated temperatures for centuries, as there are many methods available for achieving high temperature. Attaining high pressure conditions in the laboratory, however, has historically proved much more problematic.

14 March 2016: Helping the Earth suck carbon
Ari Phillips for Fusion
There’s a lot more carbon stored inside the Earth, where it benignly remains for millions of years, than there is overloading the atmosphere. But because of the discrepancy in immediate human impact, all we ever hear about are the deadly consequences of the stuff above ground as it accumulates in carbon dioxide molecules and amplifies climate change. 

14 March 2016: Rare Minerals May Be a Sign of Life
Dirk Schulze-Makuch for Smithsonian Air & Space Magazine
More than 5,000 minerals have been identified on Earth, more than half of which are classified as rare, meaning they’ve been found in five or fewer places on the planet. Robert Hazen and Jesse Ausubel recently catalogued these rare minerals for the first time. Some are so rare that the cumulative volume of all known samples is less than a cubic centimeter.
