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.

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...
The Greenland glacier Jakobshavn Isbrae is massive, at around 40 miles long and more than a mile thick. It's famous among glaciers as the source of the iceberg that sunk the Titanic—but it's...
Walruses use sea ice as platforms on which to nurse their young and launch their dives for clams and other bottom-dwellers. Each spring, walruses move northward to stay close to these perches as ice...
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...
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...
Antarctica is almost entirely covered by ice sheets up to two miles (3 km) thick, which contain roughly 70% of the world’s freshwater. The great ice sheets spill out to sea as floating ice-shelves...
The threat that climate change poses to polar bears has received a lot of attention, but they are not the only Arctic species at risk. Ice-loving seals, such as harp, hooded and ringed seals, are...
Harp seals are protected in the United States by the Marine Mammal Protection Act . Although they are not considered endangered, as sea ice melting earlier and earlier each year, available harp seal...
