From the map above:

North Pacific blue whales were known to winter at the Costa Rica Dome, a nutrient-rich upwelling that supports abundant krill. But its location shifts, so scientists aboard the Pacific Storm research vessel used satellite tagged whales to lead the way. Three of the 15 whales tagged off Santa Barbara made the migration in early 2008. Others wintered off Mexico.
