Instruments

Bottom Sediment Grab Samplers

Supplied Name: Grab Core

Supplied Description:

Collection Type: Point Water sampler (PWS), Grab Core, Gravity Core, Drill Core

Instrument Type

Generic Name: Bottom Sediment Grab Samplers

Acronym: BSGS

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/50/

Generic Description:

These samplers are designed to collect an accurate representative sample of the sediment bottom. The bite of the sampler should be deep enough so all depths are sampled equally. The closing mechanism is required to completely close and hold the sample as well as prevent wash-out during retrieval. Likewise, during descent the sampler should be designed to minimize disturbance of the topmost sediment by the pressure wave as it is lowered to the bottom.

Discrete water sampler

Supplied Name: Point Water sampler (PWS)

Supplied Description:

Collection Type: Point Water sampler (PWS), Grab Core, Gravity Core, Drill Core

Instrument Type

Generic Name: Discrete water sampler

Generic Description:

A device that collects an in-situ discrete water sample from any depth and returns it to the surface without contamination by the waters through which it passes, such as a water bottle.

Drill Core

Supplied Description:

Collection Type: Point Water sampler (PWS), Grab Core, Gravity Core, 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.

Gravity Corer

Supplied Name: Gravity Core

Supplied Description:

Collection Type: Point Water sampler (PWS), Grab Core, Gravity Core, Drill Core

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: IRMS

Supplied Description:

Samples were run on an 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).
