Marine biologist Mette Kaufman measures the temperature of a recently-drilled ice core . Variations in temperature at different points of the ice core provide information about the living conditions...
Drilling near the North Pole, Dr. Jan Backman reveals a brief moment in time when the Arctic was subtropical. More about world climate change can be found in our Climate Change featured story .
Special ships called ‘icebreakers’ are needed to access some areas of the ice-covered Arctic Ocean .
A 2011 excavation led by the Arctic Studies Center uncovered this fragment of decorated European stoneware called a bellarmine jug. Uncovering this fragment, that was likely manufactured in the 15th...
Found in Arctic waters, this rare deep-water species of larvacean , Oikopleura gorskyi , eats by filtering particles from the seawater it drifts through. Larvaceans build 'houses' around themselves...
Ice divers use a quadrat to study the density of creatures living on the underside of Arctic ice floes. A quadrat is a standardized square used to take sample measurements that allow researchers to...
Hoping to hear bowhead whales , NOAA marine mammal scientist Sue Moore listens to real-time sounds from an underwater hydrophone.
The world beneath the Arctic ice is magical, but cold. Divers have to tolerate temperatures of 30 degrees Fahrenheit (about -2° Celsius.) To stay warm they wear thermal undergarments and use special...
A dive tender monitors the line connected to ice divers studying creatures living on the underside of the Arctic Sea ice .
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...
To document fragile organisms found in the Arctic , scientist Kevin Raskoff builds special aquaria on the ship to photograph of live critters that have been captured.
About 2,500 years ago cold climate brought the first Inuit peoples into the Gulf of St. Lawrence, off the coast of Eastern Canada. Early Eskimo groups, known as Groswater Dorset, occupied many sites...
Chrysaora melanaster , one of the largest jellyfish commonly found in the Arctic, swims underneath the Arctic ice . Its tentacles can stretch to more than 3 meters long and pack a mean sting for...
A stormy sea lashes the village of Shismaref, Alaska, where the coastline has eroded 30–90 m (100–300 ft) in the past 30 years.
This copepod Calanus hyperboreus (up to 7mm in length) lives in the Arctic , usually within 500 meters of the surface. To survive the cold Arctic winters, Calanus hyperboreus builds up dense fat (...
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...
Using a drill, a team removes a chunk from the thick Arctic ice. Small samples are taken from where the ice meets liquid seawater. The ice is then melted for analysis.
Using an ROV (Remotely-Operated Vehicle) equipped with a high-definition video camera, scientists can observe the life that flourishes beneath the Arctic ice . On this expedition, they discovered...
