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.

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...
For two months, Cassandra Brooks , a marine scientist with Stanford University, travelled on an ice-breaking ship through the Ross Sea in the Antarctica—and she filmed the whole thing. A camera...
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...

The white body of the snow petrel blends in with the stark Antarctic landscape, accentuating the beautiful black eyes and beak of this seabird. They hunt in the sea ice, feeding on krill and fish...
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...
How will changes in temperature affect glaciers and ice sheets? Dr. Sarah Das from the Woods Hole Oceanographic Institution explores this phenomenon first hand in Greenland, where she studies how the...
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...
This graph of the Arctic sea ice coverage shows how close the year 2011 is to reaching a record-low . The graph contains data through September 7, 2011. The National Snow and Ice Data Center , which...
Standing at twice the height of the Adélie penguins, emperor penguins are the largest of the penguin species and can grow to be 100 pounds. This species breeds directly on the ice: a female lays her...
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...

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...
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...
