attribute NC_GLOBAL acquisition_description String Samples for this study come from CORK observatories installed at IODP Holes
U1382A and U1383C as described elsewhere (Edwards et al., 2012b). In brief,
instrument strings containing OsmoSampler systems (Wheat et al., 2011) were
deployed at different depths within the holes from 2011-2017. Additional
OsmoSampler systems were deployed at the wellhead of the CORKs in 2014 and
were inoculated with bottom seawater, making them useful for identifying
differences between crustal subsurface and bottom seawater inoculated
microbial communities. OsmoSampler systems included Flow-through Osmo
Colonization Systems (FLOCS) for mineral colonization experiments, as
described elsewhere (Ramrez et al., 2019). Each FLOCS contained sterile
(autoclaved and ethanol-rinsed) substrates including crushed basalts, pyrite,
pyrrhotite, or inert glass beads housed within polycarbonate cassettes and
sleeves. Fluids were introduced into the FLOCS via the OsmoSampler pumps,
allowing fluid microbial communities to colonize the substrates.

All FLOCS were recovered in October 2017 during cruise AT39-01 of the RV
Atlantis with the ROV Jason (Woods Hole Oceanographic Institution) following
methods described elsewhere (Ramrez et al., 2019). In brief, the instrument
strings with the downhole FLOCS were pulled up to the ship on a wire, then
immediately disassembled to store the FLOCS in a cold room. Wellhead FLOCS
incubated in milkcrates attached to crustal fluid umbilicals at the seafloor
were also collected on this cruise with the ROV. FLOCS contents were
distributed inside an ethanol-rinsed and UV-irradiated HEPA-filtered hood
using sterile instruments. Substrates for the experiment were stored cold
(2-4C) and in the dark in sterile centrifuge tubes with ultrafiltered (0.22
m-mesh Millipore Sterivex and 0.02 m-mesh Whatman Anotop 25 filters) crustal
fluid until incubation at the shore-based laboratory. Parallel samples for
initial characterization of the substrate biofilms were transferred to sterile
cyrovials, flash frozen with liquid nitrogen, and stored at -80C until
analysis. In addition to the FLOCS samples, 4-10L samples of raw and
unfiltered crustal fluids were collected into ethanol-rinsed cubitainers after
collection into gamma-irradiated bags on the seafloor using a Mobile Pumping
System. Cubitainers were stored cold (2-4C) and in the dark for approximately
one year before beginning the experiments.

A detailed description of the cathodic poised potential protocol used is
available elsewhere (Jones and Orcutt, 2019). In brief, glass two-cell, three-
electrode MFC systems (Adams and Chittenden, CA, USA) were used as incubations
chambers, run in parallel with a multichannel potentiostat (model CHI1030C,
CHI Instruments, TX, USA). Nafion 117 proton exchange membrane (Fuel Cell
Store, TX) separated the half-cells. Cells were filled with distilled water
and autoclaved prior to filling with media and sample inocula. Ag/AgCl
reference electrodes (Gamry Instruments, PA, USA part 932-00018 and/or
Analytical Instrument Systems, NY, USA) were calibrated before each run by
immersion in 3 M NaCl and compared against a known electrode kept only for
that purpose (max +/- 20 mV drift from the value of lab master electrode).
Working electrodes (WEs) were 2 4 cm2 Indium Tin Oxide (ITO) coated glass
slides (Delta Technologies Ltd, CO, USA part CB-50IN-1111), constructed for
MFC as described elsewhere (Rowe et al., 2015). Counter electrodes (CEs) were
carbon cloth with a 4 4 cm2 surface area. Electrodes were sterilized by
rinsing with 80% ethanol, air-drying, then exposing to UV radiation for 15
minutes per side.

Each experiment consisted of five treatments: Three MFCs filled with buffered
and double autoclaved crustal fluid (cool and oxic), inoculated with samples,
and incubated with a WE set poised at -200 mV versus a standard hydrogen
electrode (SHE) referred to as the Echem treatments; one MFC filled with the
same fluid and WE but without any sample inoculum referred to as the Fluid
treatment; and one glass bottle with a mixed sample inoculum and ITO electrode
without any voltage applied referred to as the Offline treatment. Samples were
transferred into the MFCs in HEPA-filtered, UV-irradiated biosafety cabinet or
hood using sterile tools. An aliquot of each sample was also collected into a
sterile plastic tube for microbial community analysis representing a time zero
(T0) condition that may have changed from the Shipboard (SB) initial
condition. For the Echem and Fluid treatments, the counter cell redox couple
was H2O/O2. Testing (data not shown) determined that a strong kill control
method was necessary to achieve sterility of the crustal fluid, consisting of
1 h autoclaving at 121C, incubation at room temperature in the dark for ~24 h
to allow for spore germination, and then another 1 h autoclaving at 121C
before cooling down to 4C for the addition of substrate. Sodium bicarbonate
was added to the media (0.1 M) as a buffer. MFCs were incubated at 4C in the
dark.

Once the MFCs were constructed, a cyclic voltammetry (CV) sweep was performed
for each cell with the potentiostat before each poised potential experiment at
a scan rate of 0.1 V s-1 and sample interval of 0.001 V, across -1 to 1 V
range. Then the chronoamperometry (CA) experiments began by applying a
constant voltage (-200 mV versus SHE) to the Echem and Fluid MFCs. Current
generation was monitored and recorded until current changes began to decline
after a period of approximately 15 days. At the end of each CA experiment, two
further CV sweeps were performed: one with the incubated ITO electrode (Tend
i) and one with a fresh ITO electrode dipped into the incubated media (Tend
ii).

attribute NC_GLOBAL projects_0_description String NSF Award Abstract:
Seawater circulates through the upper part of the oceanic crust much like groundwater flows through continental aquifers. However, in the ocean this seawater circulation, many times heated by buried magmatic bodies, transports and releases 25% of the Earth's heat. The rate of fluid flow through ocean crust is estimated to be equal to the amount of water delivered by rivers to the ocean. Much of what we know of this subseafloor fluid flow comes from studies in the eastern Pacific Ocean on ocean crust created by medium and fast spreading mid-ocean ridges. These studies indicate that seawater and its circulation through the seafloor significantly impact crustal evolution and biogeochemical cycles in the ocean and affect the biosphere in ways that are just now beginning to be quantified and understood. To expand this understanding, this research focuses on fluid flow of seafloor generated by slow spreading ridges, like those in the Atlantic, Indian and Arctic Oceans because it is significantly different in structure, mineralogy, and morphology than that formed at fast and intermediate spreading ridges. This research returns to North Pond, a long-term; seafloor; fluid flow monitoring site, drilled and instumented by the Ocean Drilling Program in the Atlantic Ocean. This research site was punctured by boreholes in which fluid flow and geochemical and biological samplers have been deployed for a number of years to collect data and samples. It also provides resources for shipboard and on-shore geochemical and biological analysis. Broader impacts of the work include sensor and technology development, which increases infrastructure for science and has commercial applications. It also provides training for students and the integration of education and research at three US academic institutions, one of which is an EPSCoR state (Mississippi), and supports a PI whose gender is under-represented in sciences and engineering. Public outreach will be carried out in conjunction with the Center for Dark Energy Biosphere Investigations.
This project completes a long-term biogeochemical and hydrologic study of ridge flank hydrothermal processes on slow-spreading, 8 million year old crust on the western flank of the Mid-Atlantic Ridge. The site, North Pond, is an isolated northeast-trending sediment pond, bounded by undersea mountains that have been studied since the 1970s. During Integrated Ocean Drilling Program Expedition 336 in 2011 and an expedition five months later (2012), sensors, samplers, and experiments were deployed in four borehole observatories drilled into the seafloor that penetrated into volcanic crust, with the purpose of monitoring changes in hydrologic properties, crustal fluid composition and mineral alteration, among other objectives. Wellhead sampling in 2012 and 2014 already revealed changes in crustal fluid compositions; and associated pressure data confirm that the boreholes are sealed and overpressured, reflecting a change in the formation as the boreholes recover from drilling disturbances. This research includes a 13-day oceanographic expedition and use of on-site robotically operated vehicles to recover downhole instrument packages at North Pond. It will allow the sampling of crustal fluids, recovering pressure data, and measuring fluid flow rates. Ship- and shore-based analyses will be used to address fundamental questions related to the hydrogeology of hydrothermal processes on slow-spread crust.
