North Pond Circulation Obviation Retrofit Kit (CORK) dissolved ion concentrations from samples collected using the Medium Volume Bag Sampler (MVBS) system during ROV Jason-II dives on Maria S. Merian in 2012-2014 (North Pond Microbes project)

Abstract:

This dataset includes Circulation Obviation Retrofit Kit (CORK) dissolved ion concentrations from borehole samples collected using the Medium Volume Bag Sampler (MVBS) system from North Pond, an isolated sediment pond located on the Western flank of the mid-Atlantic Ridge, collected during ROV Jason-II dives on Maria S. Merian in 2012.

Methods & Sampling

Standard Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) run on 0.2um filtered, acidified, subsamples from fluid sampling from IODP CORK Observatories.

Details for ROV sampling instrumentation are provided in Cowen, et al (2012).

These site descriptors 'shallow' and 'deep' refer to the umbilical that is in the borehole system. Shallow, medium and deep refers to the depth in the upper basaltic crust where the umbilical terminates.

Data Processing Description

BCO-DMO Processing:
- Added conventional header with dataset name, PI name, version date
- Modified column headers to conform to BCO-DMO naming conventions.

Instruments

GeoMICROBE

Supplied Description:

Autonomous sled with sensors and fluid sampling system.

Instrument Type

Generic Name: GeoMICROBE

Generic Description:

Integrated Ocean Drilling Program borehole CORK (Circulation Obviation Retrofit Kit) observatories provide long-term access to hydrothermal fluids circulating within the basaltic crust (basement), providing invaluable opportunities to study the deep biosphere. We describe the design and application parameters of the GeoMICROBE instrumented sled, an autonomous sensor and fluid sampling system. The GeoMICROBE system couples with CORK fluid delivery lines to draw large volumes of fluids from crustal aquifers to the seafloor. These fluids pass a series of in-line sensors and an in situ filtration and collection system. GeoMICROBE’s major components include a primary valve manifold system, a positive displacement primary pump, sensors (e.g., fluid flow rate, temperature, dissolved O2, electrochemistry-voltammetry analyzer), a 48-port in situ filtration and fluid collection system, computerized controller, seven 24 V-40 A batteries and wet-mateable (ODI) communications with submersibles. This constantly evolving system has been successfully connected to IODP Hole 1301A on the eastern flank of the Juan de Fuca Ridge.

Inductively Coupled Plasma Optical Emission Spectrometer

Supplied Name: UH_ICPOES

Supplied Description:

Instrument Type

Generic Name: Inductively Coupled Plasma Optical Emission Spectrometer

Acronym: ICP-OES or ICP-AES

Generic Description:

Also referred to as an Inductively coupled plasma atomic emission spectroscope (ICP-AES). These instruments pass nebulised samples into an inductively-coupled gas plasma (8-10000 K) where they are atomised and excited. The de-excitation optical emissions at characteristic wavelengths are spectroscopically analysed. It is often used in the detection of trace metals.
