attribute NC_GLOBAL summary String Estimated ages for Antarctic toothfish using otoliths prepared via the bake, grind and polish method were validated and reported on by Brooks et al. 2011. The otoliths validated in the study by Brooks et al. 2011 serve as a reference set for all aging activities in the Brooks Lab and are permanently housed at the University of Colorado Boulder. The reference set collection was randomly sampled from a larger sample of 1,508 otoliths by Brooks et al. (2011).\n\nEstimated ages for the reference set collection for both viewing methods investigated (Monitor versus Direct) for the three readers in this study are defined in the dataset as HK, CG and RL. This study compared the precision and bias between the two viewing methods. The estimated ages established in the study by Brooks et al. 2011 by Reader 1 for the 185 otoliths selected for this study were compared with the consensus image view age estimates to serve as a between-method \"proxy\" comparison since both studies used the same otoliths. Reference set ages by Reader 1 in the Brooks et al. 2011 study are defined in the dataset as CB Direct R12. Note digits associated with each reader/method combination in each column header, for example HK Direct R14, represents the 14th time the reference set was aged by that ager. Individual readers may have required additional reads relative to other agers, however only the last two final reads of the reference set for each ager are reported on here as they served as the basis for comparison analyses.
