Earth's polar regions are the areas of the globe surrounding the poles, north of the Arctic circle, or south of the Antarctic Circle. They are characterised by the polar climate, extremely cold temperatures, heavy glaciation, and extreme variations in daylight hours, with 24 hour daylight in summer (the midnight sun), and permanent darkness at mid-winter. The North Pole and South Pole being the centres, these regions are dominated by the polar ice caps, resting respectively on ocean and the continent of Antarctica.

There are many settlements in Earth's north polar regions, but none except for scientific bases in the south polar regions, which are colder than the northern polar regions.

Other planets and natural satellites in the solar system have interesting quirks about their polar regions. Earth's Moon is thought to contain substantial deposits of ice in deep craters in its polar regions, which never see direct sunlight. Mars, like Earth, has polar caps, but unlike Earth's icy caps they consist mostly of carbon dioxide. On Uranus, meanwhile, the extreme tilt of the planet's axis leads to the unique situation during the Uranian year of first one pole and then the other pointing almost directly at the Sun.

We are often asked what compels us to want to see Antarctica. The answer is simple, Antarctica is nature in its purest state; her power and beauty are at once humbling, confronting and exhilarating. Indeed Antarctica touches the soul like no other place on earth. The pace can be as fast as an ice wall cracking and tumbling into the sea or as slow as an advancing glacier.

Diving in Antarctica is truly an expedition in itself, every plunge into its icy waters is different than the previous one. There is no such thing as a "better dive location" because each year the ice and weather conditions change, which makes these underwater adventures so unpredictable.

Eco-Photo Explorers has once again returned from the end of the world. This time our adventure took us further south and through the Antarctic Circle. It has long held a fascination for explorers and adventurers the world over. Here we will describe our journey south to Ushuaia, Argentina and our experience diving in the Beagle Channel. Here, we explored lush kelp forests and observe giant King Crabs. The trip south to Antarctica took us across the turbulent Drake Passage and along the pristine wilderness of the Antarctic Peninsula and through the ice-choked waters below the Antarctic Circle.
