Half a century of coastal temperature records reveal complex warming trends in western boundary currents.

ABSTRACT: Accelerated warming of western boundary currents due to the strengthening of subtropical gyres has had cascading effects on coastal ecosystems and is widely expected to result in further tropicalization of temperate regions. Predicting how species and ecosystems will respond requires a better understanding of the variability in ocean warming in complex boundary current regions. Using three ≥50 year temperature records we demonstrate high variability in the magnitude and seasonality of warming in the Southwest Pacific boundary current region. The greatest rate of warming was evident off eastern Tasmania (0.20 °C decade^-1), followed by southern New Zealand (0.10 °C decade^-1), while there was no evidence of annual warming in northeastern New Zealand. This regional variab
