This study aims to understand Rainbow Smelt life history traits in Beaufort Sea's nearshore waters. Our objective is to analyze Rainbow Smelt otolith 88Sr concentrations and 86/87Sr ratios in marine and freshwater sites. We hypothesize that there are higher 88Sr concentrations and 86/87Sr ratios in marine otolith edges.
