Laboratory results on mussel larvae mass spec headers collected at Louisiana State Univeristy in 2014 (OA Proxies project)

Abstract:

These data are the headers from the mass spectrometer runs of mussel larvae shells, conducted on 6 and 13/14 March 2015. Includes 27 isotopes: 7Li, 11B, 23Na, 24Mg, 25Mg, 26Mg, 27Al, 31P, 39K, 42Ca, 43Ca, 44Ca, 51V, 53Cr, 55Mn, 59Co, 60Ni, 65Cu, 86Sr, 88Sr, 89Y, 138Ba, 139La, 140Ce, 208Pb, 232Th, 238U.

Not yet provided.

?? [The concentrations of isotopes in each mussel were analyzed using a laser ablation inductively coupled plasma mass spectrometer (LA-ICPMS; Cetac LSX-213; 213 nm laser coupled to an iCap Qc ICPMS) located in the Department of Geology and Geophysics at Louisiana State University. ...measured in the Secondary Ion Mass Spectrometry Labs at Arizona State University using a Cameca IMS 3F.??]

Data Processing Description

BCO-DMO Data Processing:

In order to serve on the BCO-DMO system, these changes were made to the originally submitted files:
- headers were split off from data
- separated each pair of meta/value into single record
- sorted files by time_start
- added columns for sample_type, date, run, sample, time_start, meta, and value

Instruments

Inductively Coupled Plasma Mass Spectrometer

Supplied Name: ICP Mass Spec

Supplied Description:

LA-ICPMS; Cetac LSX-213; 213 nm laser coupled to an iCap Qc ICPMS located in the Department of Geology and Geophysics at Louisiana State University.

Instrument Type

Generic Name: Inductively Coupled Plasma Mass Spectrometer

Acronym: ICP Mass Spec

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB15/

Generic Description:

An ICP Mass Spec is an instrument that passes nebulized samples into an inductively-coupled gas plasma (8-10000 K) where they are atomized and ionized. Ions of specific mass-to-charge ratios are quantified in a quadrupole mass spectrometer.

Mass Spectrometer

Supplied Name: Mass Spec

Supplied Description:

Cameca IMS 3F located at the Secondary Ion Mass Spectrometry Labs at Arizona State University

Instrument Type

Generic Name: Mass Spectrometer

Acronym: Mass Spec

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

Generic Description:

General term for instruments used to measure the mass-to-charge ratio of ions; generally used to find the composition of a sample by generating a mass spectrum representing the masses of sample components.
