Hidden beneath Arctic ice is a world few have ever seen. Take the icy plunge with a team of ice-loving scientists.
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...
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...
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...
At a recent staff meeting a Smithsonian colleague mentioned that one of his pastimes this summer has been keeping tabs on the Arctic sea ice. The question that's on many Arctic-watchers' minds is...
The elegant Antarctic minke whale feeds on krill (tiny crustaceans) during the winter. Groups of minke whales often are found on the edges of pack ice feasting so that they can grow thick layers of...

New technology is making it possible for scientists to go where they’ve never gone before, the depths of the icy Arctic Ocean . By collecting organisms and mapping the seafloor, researchers can...
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...
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...
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...
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...
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...

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 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...
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...
