The Gulf of California in the Northeast Pacific Ocean. Black dots are the locations of the 13 reproductive colonies of California sea lions (Zalophus californianus), numbered from north to south. The green asterisks are the locations of the predicted sea surface temperature data used in this study. The map was created with the package “ggplot2” (https://cran.r-project.org/web/packages/ggplot2/index.html) in R (https://www.r-project.org/).
