Figure S1. Mean surface current (m/s) in the Southwest Indian Ocean during the winter 1995-2009 according to the SWIO12 climatological model. Southward branch of the South equatorial current represents the East Madagascar Current (EMC). Stars represent the well-known breeding areas of humpback whales in Madagascar (Cerchio et al. 2008, 2009). Figure S2a. Movements of each humpback whale tracked in this study (2012-2014) after application of SSSM to filtered Argos locations to estimate improved locations. The top left map shows the whale tracks removed from analyses. Note that two whale tracks are shown on each figure. The colour scale indicates the bathymetric depth (m). The temporal progression is represented with continuous colour gradients (the first initial location after tagging is represented in purple or brown and the final location is represented in pink or yellow). Stars and dotted lines indicate tracks with an oceanic part. Figure S2b.

The temporal progression is represented with continuous colour gradients (the first initial location after tagging is represented in purple or brown and the final location is represented in pink or yellow). Stars and dotted lines indicate tracks with an oceanic part. Supplement S1. Projection of C on T vector (PCT) was calculated as C x cos (Ac-At) where C is the current speed, Ac is the direction of the C vector and At is the direction of the T vector. The projection of H vector on T one (PHT) is calculated in the same way with the appropriate changes. Table S1. Summary of environmental variables for each whale coastal track. Values are presented as mean ± se. Individuals include females (F) alone or with calves and males (M). Distance from shore is the average of distances between closest positive bathymetric value and each whale position. Stars indicate that mean values were computed on all location values whereas mean values used in statistical tests were computed by individual. Table S2.AIC values for top of linear mixed effects models describing the influence of environmental parameters on each behavioral metric (df = degrees of freedom, AIC = Akaike Information Criterion). Table S3. Summary of environmental variables for each whale oceanic movements. Values are presented as mean ± se. Figure S3. Density distributions of the distance from shore for females and males during coastal movements. Figure S4a. Maps of female coastal movements showing b-mode values for each estimated location. It ranges from 1, meaning low probability of localized movement and 2 meaning high probability of localized movement. In alphabetical order: whale 4, whale 7, whale 9, whale 10, whale 12, and whale 15. Figure S4b. Maps of female coastal movements showing b-mode values for each estimated location. It ranges from 1, meaning low probability of localized movement and 2 meaning high probability of localized movement. In alphabetical order: whale 20, whale 21 whale 22, whale 23, and whale 25. Figure S5a. Male coastal movements showing b-mode values for each estimated location. It ranges from 1, meaning low probability of localized movement and 2 meaning high probability of localized movement. In alphabetical order: whale 1, whale 2, whale 3, whale 6, whale 11, and whale 17. Figure S5b. Male coastal movements showing b-mode values for each estimated location. It ranges from 1, meaning low probability of localized movement and 2 meaning high probability of localized movement. In alphabetical order: whale 18, and whale 19. Figure S6. Density distributions of b-mode values for females and males during coastal movements. Figure S7a. Current speed for each whale oceanic location of whales 1, 7, 9 and 12. Colour scale shows the compensation angles. Figure 7b. Current speed for each whale oceanic location of whales 13, 17 and 22. Colour scale shows the compensation angles. Figure 8.
