attribute	NC_GLOBAL	acquisition_description	String	Alkaline phosphatase (AP) activity was measured using the fluorogenic substrate 4-methylumbelliferyl phosphate (MUF-P) (Sigma-Aldrich, St. Louis, MO) and its reference standard, methylumbelliferone (MUF). Fluorescence was measured using black, flat bottom, 96-well microplates in a Spark 10M Multimode Microplate Reader (Tecan, M\u00e4nnedorf, Switzerland). Fluorescence of MUF is greatest at pH 10, therefore 25 \u03bcL of 0.4 M NaOH was added to the wells (final concentration 40 mM) to be read. 25 \u03bcL of 1M EDTA was added as well (100 mM final concentration) to prevent precipitation of c 439 arbonate from sampled veins. Fluorescence was measured with an excitation wavelength of 380 nm and emission of 454 nm for all substrates and standards. One cm3 powdered rock was mixed with 5 cm3 of sterileartificial seawater (ASW) in a 8 mL serum vial with 90:5:5 N2:CO2:H2 headspace. 700 \u03bcL of each slurry was withdrawn with a sterile syringe to a 1.5 mL Eppendorf tube after setup but before sealing the vial; this sample served as T0, with triplicate 200 \u03bcL technical replicates. These 700 \u03bcL samples were briefly centrifuged (60 sec. at 2500 rpm) and the supernatant used for the T0 analyses. Two additional samples were taken using the same methods as for T0 after at least 2 weeks and then again after 4-6 weeks to generate a slope of activity. Incubations were kept at 10\u02daC, the inferred in situ temperature, for the duration of each assay. Autoclaved, powderized rock from each of the samples was tested to determine the amount of fluorophore adsorbance to rock powder. Adsorbance was found to behave in a systematic manner, resulting in a straight line when comparing fluorescence standards in artificial seawater (ASW) alone with fluorescence standards plus rock powder in ASW, although this relationship was found to be different when measured at 4 hours versus days later. Therefore, a correction factor for adsorbance was applied to the enzyme data for the initial measurement (t0, y=1.90x-676), taken <2 hours after experiment initiation, versus the second and third measurements (t1 and t2, y = 4.64x - 303), taken days to weeks later. Negative controls consisting of the same ASW used for the sample incubations plus substrate, but no sample, were consistently below detection. The limit of quantification for the AP assay, defined as 3X the standard deviation of the blank, was 0.0242 pmol cm-3 rock hour-1 based on analysis of eight blanks.

attribute	NC_GLOBAL	instruments_2_description	String	Plate readers (also known as microplate readers) are laboratory instruments designed to detect biological, chemical or physical events of samples in microtiter plates. They are widely used in research, drug discovery, bioassay validation, quality control and manufacturing processes in the pharmaceutical and biotechnological industry and academic organizations. Sample reactions can be assayed in 6-1536 well format microtiter plates. The most common microplate format used in academic research laboratories or clinical diagnostic laboratories is 96-well (8 by 12 matrix) with a typical reaction volume between 100 and 200 uL per well. Higher density microplates (384- or 1536-well microplates) are typically used for screening applications, when throughput (number of samples per day processed) and assay cost per sample become critical parameters, with a typical assay volume between 5 and 50 µL per well. Common detection modes for microplate assays are absorbance, fluorescence intensity, luminescence, time-resolved fluorescence, and fluorescence polarization.

attribute	NC_GLOBAL	projects_0_acronym	String	Subseafloor Lower Crust Microbiology
attribute	NC_GLOBAL	projects_0_description	String	NSF abstract: The 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. Given 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. About the study area: The 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.
