Ice

Cold, white or clear, and glistening. Ice can be found in many forms, from the Antarctic, to Arctic, or simply floating along in the form of an iceberg. The world’s ice is changing due to human influence, so watching and learning from those changes is even more important than ever.

Looking through this iceberg's reflection in the Antarctic water, you can see the iceberg below the surface—some 90% of its total volume. Icebergs are pieces of freshwater ice broken off of glaciers or ice shelves, left to float...

The Ross Sea, a 1.9 million square mile (3.6 million square km) stretch of ocean off the coast of Antarctica, has been nicknamed “ The Last Ocean .” And it’s not just a ploy to get your attention. In...
Weddell seals grind their teeth on holes in the ice to keep them open to their comings and goings between ocean and air. Their dives can last over an hour when they are looking for an opening in the...
Hidden beneath Arctic ice is a world few have ever seen. Take the icy plunge with a team of ice-loving scientists.
by Hannah Waters To really see a glacier move, you first have to speed up the passage of time. What appears to be an unmoving frozen expanse, as solid as the ground beneath your feet, is in fact a...
Small Adélie penguins live throughout the Antarctic, but are most abundant in the area of the Ross Sea. They lay eggs on the few rocky outcrops of land not covered in ice. Scientists have determined...
Every year as the sun disappears for the winter, the surface waters around Antarctica freeze into a slab of ice 10-feet thick, which effectively doubles the size of the continent. In the summer, the...
Sea ice is typically viewed as the domain of physical and natural scientists, the oceanographers, marine biologists, climate modelers, and navigators of the world. It is easy to forget another...
It’s confirmed: both Antarctica and Greenland are losing ice —around 350 billion tons each year—and, as a result, sea level has risen 11.1 millimeters worldwide since 1992. This photo shows a...
Strapped in to a harness on the back deck of a 230-foot research vessel off the coast of Antarctica , I take a moment to take in my surroundings. For as far as the eye can see bleached white ice...
