Two months earlier we should have had perpetual daylight in these latitudes; but already we had had three or four hours of night, and by and by there would be six months of darkness in these circumpolar regions.
The case of America alone would almost suffice to prove its truth: for if we exclude the northern parts where the circumpolar land is almost continuous, all authors agree that one of the most fundamental divisions in geographical distribution is that between the New and Old Worlds; yet if we travel over the vast American continent, from the central parts of the United States to its extreme southern point, we meet with the most diversified conditions; the most humid districts, arid deserts, lofty mountains, grassy plains, forests, marshes, lakes, and great rivers, under almost every temperature.
Gathering information on the Antarctic Circumpolar Current, the largest ocean current in the world, the instrument was due to spend two years collecting data at a depth of 1,100 metres, before being recovered on Christmas Day in 2013 by a research expedition on the Royal Research Ship James Clark Ross.
The Antarctic Circumpolar Current is three times bigger than the Gulf Stream and connects all three major ocean basins, transporting heat and carbon between them.

states, Capella is circumpolar. One of the pleasures of a warm summer evening here at latitude 49[degrees] is watching Capella wildly scintillating low in the north.
The seafloor animals of the Southern Ocean shelf have long been isolated by the deep ocean surrounding Antarctica and the Antarctic Circumpolar Current, with little scope for southward migration, according to the research team.

It is important to recognize the existence of two separate planetary-scale circumpolar vortices: one in the stratosphere and the other in the troposphere.
The International Union for Conservation of Nature recognizes 19 subpopulations of polar bears (scientific name Ursus maritimus), all of which "live throughout the ice-covered waters of the circumpolar Arctic." While listing the bears as a vulnerable species, IUCN says in its ( Red List : "Loss of Arctic sea ice due to climate change is the most serious threat to polar bears throughout their circumpolar range."
