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...
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...
Sea stars ( Odontaster validus ) and sea urchins ( Sterechinus neumayeri ) spread over an algae-covered seafloor off the coast of Antarctica. These two species are often found living in association...
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...
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...
At the Poles, Life Thrives Located beside the Shores and Shallows gallery (which highlights different kinds of coastal ecosystems around the world), the Poles area will take you to the ends of the...
Bright colors seem to jump off of this comb jelly, or ctenophore. The rainbow effect appears when light emanates from comb jellies' namesake combs, which are rows of cilia that run up and down their...
Hedbergella sliteri - this specific specimen is the "holotype" for this species. That means it is the reference point for what all members of the species should look like. This specimen was...
The National Ice Center’s work is focused on ensuring safe and efficient navigation, but it also supports scientific research and provides crucial information used by scientists to better monitor and...
Did you know that over 17,000 species thrive in the deep sea where no light penetrates the ocean waves? Or that an old restaurant menu can teach us about the history of fish populations? Or that...
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...
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...
Seasons in the Ross Sea are marked by ice freezing and melting, and these processes mix the seawater and redistribute salt and nutrients. The influx of nutrients cause phytoplankton to bloom, forming...
Three distinct types of killer whale, or orcas, can be found in the Antarctic, each with a different habitat and diet preference. One type of orca preys almost exclusively on the Antarctic minke...
"Cold-Water Diving: Going to Extremes for Research" is a video produced by Woods Hole Oceanographic Institution (WHOI) that shows the focus needed to do scientific work in cold water. The gear is...
The New Zealand Sub-Antarctic Islands site was inscribed on the World Heritage List in 1998. The islands are particularly notable for the abundance and diversity of nesting pelagic seabirds and...
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...
