"Frozen rock material was crushed as above, and then ground quickly into a fine
powder using a precooled sterilized mortar and pestle, and then RNA extraction
started immediately. The jaw crusher was cleaned and rinsed with 70% ethanol
and RNaseZap\\u2122 RNase Decontamination Solution (Invitrogen, USA) between
samples. About 40 g of material was extracted for each sample using the RNeasy
PowerSoil Total RNA Isolation Kit (Qiagen, USA) according to the
manufacturer\\u2019s protocol with the following modifications.
Each sample was evenly divided into 8 Bead Tubes (Qiagen, USA) and then 2.5 mL
of Bead Solution were added into the Bead Tube followed by 0.25 mL of Solution
SR1 and 0.8 mL of Solution SR2. Bead Tubes were frozen in liquid nitrogen and
then thawed at 65\\u00b0C in a water bath three times. RNA was purified using
the MEGAclear Transcription Clean-up Kit (Ambion, USA) and concentrated with
an overnight isopropanol precipitation at 4 \\u00b0C. Trace amounts of
contaminating DNA were removed from the RNA extracts using TURBO DNA
free\\u2122 (Invitrogen, USA) as directed by the manufacturer.
To ensure DNA was removed thoroughly, each RNA extract was treated twice with
TURBO DNase (Invitrogen, USA). A nested PCR reaction (2 x 35 cycles) using
bacterial primers was used to confirm the absence of DNA in our RNA solutions.
RNA was converted to cDNA using the Ovation\\u00ae RNA-Seq System V2 kit
(NuGEN, USA) according to the manufacturer\\u2019s protocol to preferentially
prime non-rRNA sequences. The cDNA was purified with the MinElute Reaction
Cleanup Kit (Qiagen, USA) and eluted into 20 \\u03bcL elution buffer. Extracts
were quantified using a Qubit Fluorometer (Life Technologies, USA) and cDNAs
were stored at -80 \\u00b0C until sequencing using 150 bp paired-end Illumina
NextSeq 550.
To control for potential contaminants introduced during drilling, sample
handling, and laboratory kit reagents, we sequenced a number of control
samples as above. Two samples controlled for potential nucleic acid
contamination; a \\u201cmethod\\u201d control to monitor possible contamination
from our laboratory extractions, which included ~ 40 g sterilized glass beads
processed through the entire protocol in place of rock, and a \\u201ckit\\u201d
control to account for any signal coming from trace contaminants in kit
reagents, which received no addition. In addition, 3 more controls were
extracted: a sample of the drilling mud (Sepiolite), and two drilling seawater
samples collected during the first and third weeks of drilling. cDNA obtained
from these controls were sequenced together with the rock samples and co-
assembled. Trimmomatic (v. 0.32) was used to trim adapter sequences
(leading=20, trailing=20, sliding window=04:24, minlen=50). Paired reads were
further quality checked and trimmed using FastQC (v. 0.11.7) and FASTX-toolkit
(v. 0.014). Downstream analyses utilized paired reads. After co-assembling
reads with Trinity (v. 2.4.0) from all controls (min length 150 bp), Bowtie2
(v. 2.3.4.1, 50) was used (with the parameter \\u2018un-conc\\u2019) to align
all sample reads to this co-assembly. Reads that mapped to our control co-
assembly allowing 1 mismatch were removed from further analysis (23.5-68.5% of
sequences remained in sample data sets, see Supplementary Table 4).
Trinity (v. 2.4.0) was used for de novo assembly of the remaining reads in
sample data sets (min. length 150 bp). Bowtie aligner was used to align reads
to assembled contigs, RSEM was used to estimate the expression level of these
reads, and TMM was used to perform cross sample normalization and to generate
a TMM-normalized expression matrix. Within the Trinotate suite, TransDecoder
(v. 3.0.1) was used to identify coding regions within contigs and functional
and taxonomic annotation was made 622 by BLASTx and BLASTp against UniProt,
Swissprot (release 2018_02) and RefSeq non-redundant protein sequence (nr)
databases (e-value threshold of 1e-5). BLASTp was used to look for sequence
homologies with the same e-values. HMMER (v. 3.1b2) was used to identify
conserved domains by searching against the Pfam (v31.0) database. SignalP (v.
4.1) and TMHMM (2.0c) were used to predict signal peptides and transmembrane
domains. RNAMMER (v.1.2) was used to identify rRNA homologies of archaea,
bacteria and eukaryotes.
Because the Swissprot database does not have extensive representation of
protein sequences from environmental samples, particularly deep-sea and deep
biosphere samples, annotations of contigs utilized for analyses of selected
processes were manually cross checked by BLASTx against GenBank nr database.
Aside from removing any reads that mapped well to our control co-assembly (1
mismatch), as an extra precaution, any sequence that exhibited \\u2265 95%
sequence identity over \\u2265 80% of the sequence length to suspected
contaminants (e.g., human pathogens, plants, or taxa known to be common
molecular kit reagent contaminants, and not described from the marine
environment) as in Salter et al. and Glassing et al. were removed. This
conservative approach potentially removed environmentally relevant data that
were annotated to suspected contaminants due to poor taxonomic representation
from environmental taxa in public databases, however it affords the highest
possible confidence about any transcripts discussed.
Additional functional annotations of contigs were obtained by BLAST against
the KEGG, COG, SEED, and MetaCyc databases using MetaPathways (v. 2.0) to gain
insights into particular cellularprocesses, and to provide overviews of
metabolic functions across samples based on comparisons of FPKM-normalized
data. All annotations were integrated into a SQLite database for further
analysis.";

"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.";

Data Access Protocol (DAP) and its
selection constraints.
The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.
Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names,
followed by a collection of
constraints (e.g., variable<value),
each preceded by '&' (which is interpreted as "AND").
