attribute NC_GLOBAL acquisition_description String Powderized rock material 462 from each sample (produced in the laminar flow\nhood on the JOIDES Resolution using a sterile mortar and pestle) was\nimmediately transferred to sterile, muffled glass containers and stored in a\ndesiccator until analysis of carbon and nitrogen according to established\nmethods. Briefly, samples were weighed into methanol rinsed silver boats (4 x\n6 mm, Costech). 96-well glass plates (combusted 4 hrs at 450\\u00b0C) holding\nthese samples were placed in a vacuum desiccator that also contained an open\ndish with about 50 mL fresh, concentrated (12N) HCl. An inverted\ncrystallization dish was placed over the samplesto protect them from water\ncondensation. The desiccator was closed and pumped out with an airdriven\naspirator, to a reading of about ~ 0.5 atm and the desiccator was placed in an\noven kept between 60 and 65 \\u00b0C. Acidification was allowed to run for 60\nto 72 hours. When acidification was complete, the samples were removed and set\nin the oven to dry (60-65 \\u00b0C), and then placed in a vacuum desiccator\ncharged with indicating silica gel (Fisher S162-500, activated by heating\nabove 220 \\u00b0C for several hours) and pumped down again and dried for about\n24 hours.\n \n\\u00a0

attribute NC_GLOBAL project String Subseafloor Lower Crust Microbiology
attribute NC_GLOBAL projects_0_acronym String Subseafloor Lower Crust Microbiology
attribute NC_GLOBAL projects_0_description String NSF abstract:\nThe lower ocean crust has remained largely unexplored and represents one of the last frontiers for biological exploration on Earth. Preliminary data indicate an active subsurface biosphere in samples of the lower oceanic crust collected from Atlantis Bank in the SW Indian Ocean as deep as 790 m below the seafloor. Even if life exists in only a fraction of the habitable volume where temperatures permit and fluid flow can deliver carbon and energy sources, an active lower oceanic crust biosphere would have implications for deep carbon budgets and yield insights into microbiota that may have existed on early Earth. This is all of great interest to other research disciplines, educators, and students alike. A K-12 education program will capitalize on groundwork laid by outreach collaborator, A. Martinez, a 7th grade teacher in Eagle Pass, TX, who sailed as outreach expert on Drilling Expedition 360. Martinez works at a Title 1 school with ~98% Hispanic and ~2% Native American students and a high number of English Language Learners and migrants. Annual school visits occur during which the project investigators present hands on-activities introducing students to microbiology, and talks on marine microbiology, the project, and how to pursue science related careers. In addition, monthly Skype meetings with students and PIs update them on project progress. Students travel to the University of Texas Marine Science Institute annually, where they get a campus tour and a 3-hour cruise on the R/V Katy, during which they learn about and help with different oceanographic sampling approaches. The project partially supports two graduate students, a Woods Hole undergraduate summer student, the participation of multiple Texas A+M undergraduate students, and 3 principal investigators at two institutions, including one early career researcher who has not previously received NSF support of his own.\nGiven the dearth of knowledge of the lower oceanic crust, this project is poised to transform our understanding of life in this vast environment. The project assesses metabolic functions within all three domains of life in this crustal biosphere, with a focus on nutrient cycling and evaluation of connections to other deep marine microbial habitats. The lower ocean crust represents a potentially vast biosphere whose microbial constituents and the biogeochemical cycles they mediate are likely linked to deep ocean processes through faulting and subsurface fluid flow. Atlantis Bank represents a tectonic window that exposes lower oceanic crust directly at the seafloor. This enables seafloor drilling and research on an environment that can transform our understanding of connections between the deep subseafloor biosphere and the rest of the ocean. Preliminary analysis of recovered rocks from Expedition 360 suggests the interaction of seawater with the lower oceanic crust creates varied geochemical conditions capable of supporting diverse microbial life by providing nutrients and chemical energy. This project is the first interdisciplinary investigation of the microbiology of all 3 domains of life in basement samples that combines diversity and \"meta-omics\" analyses, analysis of nutrient addition experiments, high-throughput culturing and physiological analyses of isolates, including evaluation of their ability to utilize specific carbon sources, Raman spectroscopy, and lipid biomarker analyses. Comparative genomics are used to compare genes and pathways relevant to carbon cycling in these samples to data from published studies of other deep-sea environments. The collected samples present a rare and time-sensitive opportunity to gain detailed insights into microbial life, available carbon and energy sources for this life, and of dispersal of microbiota and connections in biogeochemical processes between the lower oceanic crust and the overlying aphotic water column.\nAbout the study area:\nThe International Ocean Discovery Program (IODP) Expedition 360 explored the lower crust at Atlantis Bank, a 12 Ma oceanic core complex on the ultraslow-spreading SW Indian Ridge. This oceanic core complex represents a tectonic window that exposes lower oceanic crust and mantle directly at the seafloor, and the expedition provided an unprecedented opportunity to access this habitat in the Indian Ocean.
