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...
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...
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...
A cnidarian brought up from the Arctic seafloor more than 2000 meters (6562 feet) deep.
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...
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...
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...
Bivalves brought up in a box corer from the deep Arctic seafloor.
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...
An Arctic cod rests in an ice-covered space. View the “ Under Arctic Ice ” photo essay.
This species of amphipod , Eusirus holmii , was found both at the surface of Arctic waters and as deep as 2000 meters (6562 feet). Researchers have found that while the amphipod inhabits the sea ice...
Hoping to hear bowhead whales , NOAA marine mammal scientist Sue Moore listens to real-time sounds from an underwater hydrophone.
A sea star , Hymenaster pellucidus , brought up from a benthic ROV dive. View the “Under Arctic Ice” photo essay to learn more.
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...
Scientists are excited when they discover an animal where they had never seen it before. This eelpout fish, Lycodes adolfi, was seen on the Pacific side of the Arctic in 2009. Previously, scientists...
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...
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...
