Scientists document a direct relationship between the extent of sea ice and polar bear survival. Future projected reductions in the extent of annual sea-ice due to global warming may result in the...
McMurdo Station is the hub of the U.S. Antarctic Program. Since 1955, scientists have been coming to McMurdo primarily in the southern 'summer' months of October to February. Amidst the penguins and...
“As we motored around Paulet Island in a Zodiac boat, these two curious penguins waddled across an iceberg to get a closer look at us.” -- Nature's Best photographer, Phillip Colla . See more...
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...
Scientists use remotely operated vehicles , ROVs, equipped with collection devices and cameras to aid in deep-sea ocean exploration in the Arctic and in other regions of the world. It is unoccupied...
An emperor penguin chick ( Aptenodytes forsteri ) huddles under its mother's legs to keep warm in the long Antarctic winter. Learn more about research on emperor penguins and other Antarctic...
The crabeater seal ( Lobodon carcinophaga ) is found on the ice of Antarctica, but surprisingly they don't eat crabs! The seals primarily eat krill, tiny crustaceans that play a large part in the...
Lanceola clausi , the bull-dog amphipod , another rare deep-water species captured below 1000 meters (3281 feet) with the multinet . View the “Under Arctic Ice” photo essay to learn more.
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...
This pair of sea butterflies ( Limacina helicina ) flutter not far from the ocean's surface in the Arctic. Sea butterflies are a type of sea snail, but instead of dragging themselves around the...
Hoping to hear bowhead whales , NOAA marine mammal scientist Sue Moore listens to real-time sounds from an underwater hydrophone.
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...
In the icy waters of the Arctic , a deep-water larvacean (aka “sea tadpole” because it looks like a tadpole) drifts through the water in its 'house.' This house is made of protein and creates almost...
Scripps scientist Gerald Kooyman's expeditions have documented climate-induced changes to emperor penguin habitat in Antarctica. Learn more about life at the poles or check out this emperor penguin...
Arctic cod have a special protein that keeps their blood from freezing in ice-cold Arctic waters.
Even if you aren't a hardcore birder, chances are you have some hidden love for penguins. These flightless birds have captured our hearts through countless movies, beautiful images and their adorable...
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...
At the ends of the Earth, life thrives despite extreme conditions. In the Arctic and Southern Oceans, organisms have evolved adaptations to cope with year-round cold and six months of darkness. But...
