Listening In on the Past: What Can Otolith δ18O Values Really Tell Us about the Environmental History of Fishes? [PDF]

, 2014
Oxygen isotope ratios from fish otoliths are used to discriminate marine stocks and reconstruct past climate, assuming that variations in otolith δ18O values closely reflect differences in temperature history of fish when accounting for salinity induced ...
