Seasonal change

Did we say cold? Winter temperatures on the plateau can range from degrees F degress C to degrees F degrees C , while summer achieves a balmy degrees F degrees C. The coasts and the Peninsula are much warmer. Mid-summer temperatures on the peninsula can reach 60 degrees F nearly 15 degrees C , and the East Antarctic coast gets up to a whopping 32 degrees F 0 degrees C.

The coasts, on the other hand, can get heavy snowfalls of up to 1. This is a big place — over 14 million square miles — that encompasses different ecosystems and terrain. In a nutshell, you have some volcanic mountains, sand-dune like snow drifts, oases in the form of dry valleys, crevasses big cracks in the ice , glaciers and more glaciers, and ice shelves near the coasts.

The Peninsula itself is a major mountain system with rock and glaciers and many islands. Lucky tourists can watch glaciers calve, though they usually hear them before they see them. The research focused first on adaptation to the cold environment, but later scientists found out that the lack of natural sunlight in winter and the excess of natural light in the summer was probably of greater importance.

Ice forms in winter over much of the sea around Antarctica, and rapidly retreats in the spring when the ice melts. Summer is a season of long days and slightly warmer temperatures when phytoplankton can grow rapidly and produce food for the entire ecosystem. High winds blowing from the continent mix the seawater, bringing high levels of nutrients necessary for phytoplankton growth near the sea surface, where there is sunlight.

On one side of its orbit around the sun, the Earth is tilted towards the sun.
