Science Objectives | |
| OCE 1031808 (Project Leader: A. T. Fisher, 11 days) supports multidisciplinary borehole experiments in oceanic crust, to assess hydrogeologic, solute and colloid transport, and microbiological processes and properties at multiple spatial and temporal scales (meters to kilometers, minutes to years). Results of these experiments will comprise a major advance in our understanding of hydrogeologic properties and fluid processes within the volcanic oceanic crust. This grant supports scientific activities that follow completion of Integrated Ocean Drilling Program Expedition 327, which operated in Summer 2010. This expedition drilled two holes through sediments and into the volcanic crust on the 3.5 m.y. old seafloor on the eastern flank of the Juan de Fuca Ridge. These holes were drilled, cased, cored, and tested, then instrumented with subseafloor, borehole observatory systems (CORKs). The Expedition 327 CORKs augment four additional observatory systems, all located within an area of about 2.5 square kilometers, creating a network of instrumented sites where researchers are monitoring pressure and temperature at depth, and sampling fluids and microbiological material using autonomous instrumentation. These CORK systems require servicing with a submersible or remotely operated vehicle (ROV) to download data, recover samples, and replace a variety of experimental systems. This is a primary goal of the Summer 2011 expedition with the ROV Jason II and the R/V Atlantis. In addition, we will install a new flow meter on the top of one of the CORK observatories, then open a large-diameter ball valve, allowing overpressured hydrothermal fluid from the crust to flow freely into the overlying ocean. This will provide a fluid and microbiological sampling opportunity, and will create a pressure perturbation that will extend within the seafloor to the other CORK observatories. By monitoring the formation pressure response at the different observatories, located at different distances and in different directions from the CORK that will be allowed to discharge fluid, researchers will be able to assess the nature of crustal hydrologic properties. MCB-0604014 (Project Leader: J. Cowen, 1 day) is intended to collect clean samples of crustal fluid s for geochemical, microbiological and ecological characterization. Researchers are studying subseafloor microbial communities and metabolic diversity in association with geochemical processes. In situ, real-time voltammetric analyses will measure key dissolved redox species, helping to elucidate the metabolic climate of the basement fluids and guide biology portions of this research. Geochemical and biological data will serve as input parameters for thermodynamic calculations of potential metabolic reactions, which will provide a ‘reality-check’ for occurrence of specific metabolisms. Biomarkers and their carbon isotopic compositions will provide information about source organisms, carbon sources, and physiological processes. MCB-0604014 activities focus mainly on acquisition of pristine fluid samples from one or more of the six CORK observatory systems described above. OCE-0726887 (Project Leader: K. Becker, 1 day) has overall project goals similar to those described for OCE-1031808, but also was to include servicing of an additional observatory system that is not part of the IODP Expedition 327 network. This additional system was installed on younger seafloor, ~50 nmi to the west, during ODP Leg 168 in 1996. At present this CORK system is being used for formation pressure monitoring. During the Summer 2011 Atlantis/Jason II expedition, we plan to visit this CORK, download pressure data, and may attempt recovery of an additional pressure measurement system installed nearby on the seafloor. | |
Science Activities | |
| Functional goals for AT18-08 are to service of a network of six subseafloor observatories (CORKs) separated by ~40 to 2460 m, collect fluid and microbiological samples, and complete cross-hole hydrogeologic, geochemical, and microbiological experiments. Because of the close spacing between the primary CORK systems that are the focus of AT18-08, it should be possible to combine operations at multiple wellheads during a single Jason dive, but this will depend on payload, electrical connection, elevator and other operational requirements. Active pressure measurement and logging systems are currently installed in the CORKs in Holes 1026B, 1301A, 1301B, 1362A, and 1362B. Data from Hole 1026B are being downloaded automatically using the Neptune Canada cable network. Data from the other CORKs will be downloaded with Jason. Pressure download operations will include manipulation of valves to check the hydrostatic pressure offset and evaluate potential gauge drift. The CORK in Hole 1027C contains an older generation of data logger installed in the top of the wellhead and held in place by a corroded electrical connector. We intend to recover and replace the pressure logger in Hole 1027C. The current Hole 1027C data logger might still be collecting data (depending on battery performance) or, even if it is not currently logging, may be capable of providing data for download. We should be prepared to download data from the old logger, but this will be attempted only if we can't recover it from the wellhead. Once the old 1027C logger is replaced (as described in more detail below), the new logger will be downloaded at least once to verify functionality and conditions in this hole. The pressure logger installed in Hole 1024C will be downloaded on a dedicated dive, as this hole is located ~50 nmi west of our primary work site. Replacement of the pressure logging system in Hole 1027C will require a series of special operations. First, we are building a tool to remove the corroded brass electrical connector from the top of the wellhead. Once this connector is removed, we will deploy another tool to latch onto the data logger and pull it out using a hydraulic ram (driven by hydrostatic pressure). These tools will be carried to the seafloor using Jason's basket or an elevator. Once the old logger is removed, we will install an insert into the wellhead. There will be a hydraulic coupler coming off the side of the insert, near the top. We will use this coupler to connect to a hydraulic umbilical plumbed into a pressure gauge and data logger, which will be deployed on the CORK landing platform. This data logger was intended for deployment in a CORK wellhead during Expedition 327, so it has the same kind of underwater mateable connector as the pressure loggers used on other CORKs in this area. The insert placed in the Hole 1027C CORK wellhead will have a rotating clamp on top, like that deployed on the Site 1362 CORKs. We will install a solid plug in the clamp during Summer 2011 Jason operations, but a plug supporting additional instrumentation (for fluid sampling, microbiological substrate, etc) could be deployed at a later time. We are developing an autonomous flowmeter system that is to be deployed on the top of a ball valve in the wellhead of one of the Expedition 327 CORKs, most likely the one in Hole 1362B. This flowmeter will use an electro-magnetic induction sensor to determine the rate of fluid outflow from the CORK over time, with measurements made every 15-60 minutes for the following year. The flowmeter will be held in place with a rotating clamp built into a ball valve positioned in one of the wellhead bays. Opening that valve will start a long-term flow experiment, which will last for at least 12 months, as the overpressured formation discharges fluid at 5–10 L/s, with pressure monitoring occurring in this hole and in nearby CORKs to determine the nature of the cross-hole response. There will be a vertical pipe with a diameter of ~4 that extends upward from the flowmeter sensor by about 1 m. Four autonomous thermal loggers will be installed along the length of this pipe, to provide an independent estimate of the upward fluid flow rate (using heat as a tracer). In addition, this pipe will provide fluid and microbiological sampling opportunities. Inlets to fluid samplers can be "hung" over the top of the pipe, allowing fluids to be sampled during discharge from the hole. OsmoSampler systems are currently installed on wellheads in Holes 1026B, 1301A, and 1301B. Existing and new OsmoSampling systems include Teflon coils, copper coils, and microbiological FLOCS incubation chambers. Existing systems will be recovered and new systems will be installed at these locations and on CORKs in Holes 1362A and 1362B, which were deployed on IODP Expedition 327 without samplers in place. The OsmoSamplers installed on the CORK in Hole 1362B will draw fluids from the discharge from the flowmeter system, rather than from lines on the wellhead. Additional fluid samples will be collected from wellheads using a variety of techniques. Active pumping systems use mechanical and hydraulic pumps and will be deployed and recovered on a short-term basis (hours to days). These systems can be used to draw fluids from valves and fittings on CORK wellheads, and to sample from flow discharging from the flowmeter. NOTE: when actively sampling from CORK wellhead fittings using a mechanical/hydraulic pump system, we may need to close OsmoSampler and/or pressure monitoring valves so that we don't damage associated instruments. | |
