PCA rotated loading matrix for Galapagos and California sea lion dive parameters from Granito Island, Mexico and Caamaño Islet, Galapagos for a warm (GSL, Mar.2005 and CSL, Jul–Aug.2005) and cold season (GSL, Feb–Mar.2006 and CSL, Feb–Mar.2007). In bold are loadings from the diving variables that contributed the most for Principal components (PC) 1–4.
