Southern elephant seals from different colonies frequent specific oceanographic regions to forage. They feed most successfully in areas with specific hydrographic properties, e.g. the upwelling regions of Circumpolar Deep Water within the Antarctic Circumpolar Current. In the Southern Ocean, southern elephant seals associate more frequently with southerly, higher‐latitude fronts and frontal zones. However, the foraging success in association with these regions varies strongly according to year, season and sex. Some of the seasonal and interannual variations in foraging success can be linked to climatic changes such as positional shifts in fronts and variability associated with frontal positions. Generally, southern elephant seals appear to be resilient against the apparent variability in the location and productivity of frontal systems.
