Description

Spring 2011 -Sediment Gas Concentrations and Stable Isotope Values

Methods & Sampling

Sediment gas concentrations and stable isotope values in sediment/permaforst, Arctic Drilling Expedition April/May 2011

Samples were collected in April/May 2011
CH4 samples were collected in 20ml vials sealed with butyl rubber stopper
Gas samples were run on a flame ionization (alkanes) or thermal conductivity (carbon dioxide) detector
Stable isotope data were obtained from a gas chromatograph coupled to as stable isotope ratio monitoring mass spectrometer

Data Processing Description

BCO-DMO Processing Notes
- Generated from original file "0908788_Joye_Spring-2011_ Summary.xlsx", Sheet: "Sed Gases" contributed by Samantha Joye
- Parameter names edited to conform to BCO-DMO naming convention found at Choosing Parameter Name
- Lat and Lon converted to decimal degrees
- "nd" (no data) inserted into blank cells
- blank rows removed
- Station and Date inserted from Sediment Master Data
- "B.D.L." converted to "BDL" (periods removed) to avoid potential data errors downstream
- "N.D." converted to "nd" (periods removed) to avoid potential data errors downstream and for consistency with "nd" (see above)

Instruments

Drill Core

Supplied Description:

Instrument Type

Generic Name: Drill Core

Generic Description:

A core drill is a drill specifically designed to remove a cylinder of material, much like a hole saw. The material left inside the drill bit is referred to as the core.

Core drills are used frequently in mineral exploration where the coring may be several hundred to several thousand feet in length. The core samples are recovered and examined by geologists for mineral percentages and stratigraphic contact points. This gives exploration companies the information necessary to begin or abandon mining operations in a particular area.

Flame Ionization Detector

Supplied Name: Flame Ionizing Detector

Supplied Description:

Gas samples were run on a flame ionization (alkanes) or thermal conductivity (carbon dioxide) detector

Instrument Type

Generic Name: Flame Ionization Detector

Acronym: FID

Generic Description:

A flame ionization detector (FID) is a scientific instrument that measures the concentration of organic species in a gas stream. It is frequently used as a detector in gas chromatography. Standalone FIDs can also be used in applications such as landfill gas monitoring, fugitive emissions monitoring and internal combustion engine emissions measurement in stationary or portable instruments.

Gas Chromatograph

Supplied Description:

Stable isotope data were obtained from a gas chromatograph coupled to as stable isotope ratio monitoring mass spectrometer

Instrument Type

Generic Name: Gas Chromatograph

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB02/

Generic Description:

Instrument separating gases, volatile substances, or substances dissolved in a volatile solvent by transporting an inert gas through a column packed with a sorbent to a detector for assay. (from SeaDataNet, BODC)

Gravity Corer

Supplied Name: Gravity Core

Supplied Description:

Instrument Type

Generic Name: Gravity Corer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/51/

Generic Description:

The gravity corer allows researchers to sample sediment layers at the bottom of lakes or oceans. The coring device is deployed from the ship and gravity carries it to the seafloor. (http://www.whoi.edu/instruments/viewInstrument.do?id=1079).

Isotope-ratio Mass Spectrometer

Supplied Name: Stable Isotope Ratio Monitoring Mass Spectrometer

Supplied Description:

Stable isotope data were obtained from an gas chromatograph coupled to as stable isotope ratio monitoring mass spectrometer

Instrument Type

Generic Name: Isotope-ratio Mass Spectrometer

Acronym: IR Mass Spec; IRMS

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB16/

Generic Description:

The Isotope-ratio Mass Spectrometer is a particular type of mass spectrometer used to measure the relative abundance of isotopes in a given sample (e.g. VG Prism II Isotope Ratio Mass-Spectrometer).
