Description:"The otolith of a red snapper (Lutjanus campechanus) was analyzed for radiocarbon (¹⁴C) with a novel laser ablation (LA) apparatus coupled to the MIni CArbon DAting System (MICADAS). By prior growth zone counting in the otolith, it was estimated that the fish was 50-55 years old. The cross section of the otolith (Fig. 1) used in the LA scans was only a few hundred micrometers thick, and scanning distances did not exceed 6.5 mm. In this application, the LAAMS technique excels due to low material usage, high spatial resolution, and a quasi-continuous ¹⁴C signal along the growth axis."
