The following pages provide a brief introduction to the natural history
of the Arctic. For the purposes of these pages, I have defined this
region as the Arctic Ocean and the land area north of the treeline
(region where trees cannot grow). For a map of this region and to
read about the other definitions of the Arctic region, visit the National
Snow and Ice Data center Arctic Info page. For more detailed information
on Arctic topics, please consult the References
The Arctic Ocean is unique among the worlds oceans for many
reasons. It is largely ice-covered (much of it year-round, the rest
seasonally), it receives the majority of the fresh-water input from
the worlds rivers (mostly from the Siberian continent), and
it has an abnormally high ratio of shelf to abyssal area.

Arctic and Antarctic
The Polar regions cap the opposite ends of the earth. How do they
differ and how are they similar?
The Earth's tilt causes huge fluctuations in daylight
at the Poles. Find out more about how this affects temperature and
climate in the Arctic.
Polar bears, snowy owls, and beluga whales are only
a few of the many fascinating inhabitants of the far north. Read
this page to learn more.
This page covers the base of the food chain, from the treeless tundra to the miniature plants of the sea.
What is sastrugi? How does pack ice differ from
a growler? This page is all about ice.
The Arctic's fogbows, sundogs, and mirages make

how these optical effects are formed.
