Amino acid compound specific nitrogen isotopic analysis (AA-CSIA) data from reef fish samples collected over a 4 year period from 2008 to 2012 from the Hawaiian Islands

Expand/Collapse All

Methods & Sampling

The reef fish samples were collected over a 4 year period from 2008 to 2012 from the main Hawaiian Islands. Species of lanternfish and dragonfish were grouped as mesopelagics, as they were collected using midwater trawling equipment (see Choy et al. 2012 PLoS ONE 7(11): e50133. doi:10.1371/journal.pone.0050133 for detailed collection methods), or dipnets in the open ocean. Finally, large, open-ocean predator species were collected at sea by trained longline fishery observers of the National Oceanic and Atmospheric Administration’s (NOAA) Pacific Islands Regional Observer Program during the years 2009-2011 in the central North Pacific Subtropical Gyre.

Data Processing Description

BCO-DMO Processing:
- Modified parameter names to conform with BCO-DMO naming conventions.
- Replaced blanks (missing data) with 'nd' to indicate 'no data'.
- Transposed columns to rows for amino acid and standard deviation columns.

Instruments

Gas Chromatograph

Supplied Name: gas chromatograph

Supplied Description:

The d15N values of derivatized samples were determined using a Delta V Plus mass spectrometer interfaced to a Trace
GC gas chromatograph through a GC-C III combustion furnace.

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)

Longline Fishing Gear

Supplied Description:

Large pelagic fish tissue samples were collected at sea by trained longline fishery observers of the National Oceanic and Atmospheric Administration’s (NOAA) Pacific Islands Regional Observer Program during the years 2009-2011.

Instrument Type

Generic Name: Longline Fishing Gear

Acronym: Longline

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/90/

Generic Description:

Longlining employs a central fishing line that can range from one to 50 miles long; this line is strung with smaller lines of baited hooks, dangling at evenly spaced intervals. Longlines can be set near the surface to catch pelagic fish like tuna and swordfish, or laid on the sea floor to catch deepdwelling fish like cod and halibut.

Mass Spectrometer

Supplied Name: mass spectrometer

Supplied Description:

The d15N values of derivatized samples were determined using a Delta V Plus mass spectrometer interfaced to a Trace
GC gas chromatograph through a GC-C III combustion furnace.

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.
