Description

Geochemical concentrations (ppm) of six elements measured in otoliths of Atlantic croaker sampled on board of the R/V Oregon II during the NOAA Seamap Fall Groundfish Survey of 2014 (Oct 10 to Nov 4) and 2015 (Oct 8 to Nov 22).

Methods & Sampling

Dataset acquisition description

Otolith element concentrations for each individual fish (labeled as “HMU ####”) were measured at the University of Austin, Jackson School of Geosciences using laser ablation inductively coupled mass spectrometry. Standard reference materials included a National Institutes of Standards and Technology glass standard (NIST-612) and a United States Geological Survey microanalytical carbonate standard pressed pellet (MACS-3). Otolith element concentrations were quantified along the longest dorso-ventral axis spanning the core (i.e. hatch) to the edge (i.e. death). Please reference Altenritter et al. (2018) and Altenritter and Walther (2019) for detailed information on sampling and analysis, instrumentation, and data processing.

Data Processing Description

Dataset Processing Description

Raw element intensities were converted to element concentrations (ppm) in the data reduction program Iolite.
