A high resolution micromill has been used to isolate the otolith core from a whole otolith for elemental analysis. The effects of micromilling procedures (e.g., sectioning, embedding and drilling) on contamination to otolith trace element levels were examined using paired blackfin tuna (Thunnus atlanticus) otoliths.

Key advantages of our LA technique are, for example, high spatial resolution analyses and the possibility of rapid determination of numerous coeval sub-samples. The results on micromill samples are more precise but this sample preparation technique is time consuming and larger sample sizes than used for LA are needed for individual measurements.

Where r is resolution (the smallest resolvable distance between two objects), NA is a general term for the microscope numerical aperture, λ is the imaging wavelength, NA(obj) equals the objective numerical aperture, and NA(cond) is the condenser numerical aperture. Notice that equation (1) and (2) differ by the multiplication factor, which is 0.5 for equation (1) and 0.61 for equation (2).

Otoliths are calcified structures in the head of fish that record environmental information about fish's life history. Gathering the elemental information from the core of an otolith corresponding to the juvenile period of fish's life is critical to discriminate the adult fish to their natal habitats reliably.

Otolith samples of pen-reared cod with well-defined temperature history were obtained using a high-resolution sampling technique, and it was found that the otolith δ13C values had a cyclic pattern, roughly in phase with the δ18O values. A high-resolution sampling technique for stable-isotope measurements in otoliths is now available, but little is known about the precision and …
