Over the next two days on the Drake Passage, you enjoy some of the same experiences encountered by the great polar explorers who first charted these regions: cool salt breezes, rolling seas, maybe even a fin whale spouting up sea spray. After passing the Antarctic Convergence – Antarctica’s natural boundary, formed when north-flowing cold waters collide with warmer sub-Antarctic seas – you are in the circum-Antarctic upwelling zone.
Not only does the marine life change, the avian life changes too. Wandering albatrosses, grey-headed albatrosses, black-browed albatrosses, lightmantled sooty albatrosses, cape pigeons, southern fulmars, Wilson’s storm petrels, blue petrels, and Antarctic petrels are a few of the birds you might see.
