Data Processing Description

BCO-DMO Processing Notes
- Generated from original file "0908788_Joye_Spring 2012_Sed_Summary.xlsx", Sheet: "Sed Master" 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, Collection Type and Date values inserted
- "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:

Collection Type: Drill core

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 ionizing detector and/or IRMS

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.

Isotope-ratio Mass Spectrometer

Supplied Name: IRMS

Supplied Description:

Gas samples were run on a flame ionizing detector and/or IRMS

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).
