Feasibility of lead-radium dating the otoliths of blackfin icefish (Chaenocephalus aceratus) and ocellated icefish (Chionodraco rastrospinosus)
that the collection of otoliths from these species be given a priority whenever possible to facilitate ... determining the parameters of future applications that would lead to a validation of age. In the current study ... , sample mass for the pooled otolith samples was low (~0.4 g). This finding, coupled with low radium-226 ... levels, led to age determinations that had a high margin of uncertainty; however, the findings led to an ...
