Presented here are (1) Akaike's Information Criterion values for each model comparing oceanographic conditions or population size of leatherback sea turtles Dermochelys coriacea to median nesting date (MND) or to the central tendency of the nesting season (CTns), (2) graphs showing multidecadal trends in local air temperatures and precipation values at each of the study sites, and (3) a graph showing monthly patterns in local air temperature over the leatherback nesting season at Playa Grande.

2 Table S1. Akaike's Information Criterion (AIC) for each model comparing oceanographic conditions or population size of leatherback sea turtles Dermochelys coriacea to median nesting date (MND) or to the central tendency of the nesting season (CTns). AIC values are presented for models including only a single parameter (oceanographic conditions: before departure from the foraging area, during departure from the foraging area, during migration between foraging and nesting areas, and upon arrival at the nesting areas;

or population size) and for models with

2 parameters (oceanographic conditions and population size). Lowest values for AIC denote the best model and are indicated with an asterisk (*). Nesting locations are Playa Grande, Costa Rica (Pacific Ocean), and Sandy Point, US Virgin Islands (Atlantic Ocean). MEI: Multivariate El Ni?o-Southern Oscillation index;
