Taking science measurements in the Arctic

One of the primary purposes of the drifting stations during the Russian North Pole Drifting Station program was to collect all possible meteorological data while on the ice floe. This involved installing, calibrating, and maintaining the instruments. Here, researcher German Maximov conducts a routine calibration of a pyranometer (in the large tube)

Early Research

Indigenous people have lived in the Arctic for thousands of years. Europeans began venturing into the Arctic around one thousand years ago, as Russians and Scandinavians ventured north and west, exploring new lands and searching for shipping routes. Scientific exploration began in earnest in the 18th and 19th centuries, as people realized that there was much to learn about the Arctic climate.

In the late 1800's twelve countries participated in the first International Polar Year expedition, establishing new research stations and conducting extensive studies of oceanography, sea ice, and biology of the polar regions. The expeditions catalogued new islands, animals, and plants.

While many nations have contributed to Arctic research, Russia in particular has a long history of exploration and science in the Arctic. Large parts of Russia lie above the Arctic Circle, and the country is home to the three largest communities in the Arctic. Russians first started exploring the Arctic as early as the 11th and 12th centuries, and carried out a number of expeditions in the Russian Arctic starting in the early 18th century. In 1937, Russia established drifting stations that floated on sea ice in the Arctic Ocean, which laid the foundation for later studies of sea ice.

Today, scientists study the Arctic to learn more about how climate and weather are changing. They investigate how Arctic climate and weather interact with the rest of the world, and are working to understand how climate change will affect the region. To study the Arctic, researchers sometimes travel to the field to conduct experiments or make observations. They study the properties of snow and sea ice, digging snow pits to examine the properties of snow, or measuring the thickness of sea ice by hand to determine how the ice cover is changing. Researchers also study the frozen ground and permafrost that covers much of the Arctic lands. And biologists research the unique plants and animals that live in the Arctic.

In 2007 to 2008, researchers from around the world participated in another International Polar Year, launching international expeditions and collecting vast amounts of data about the Arctic and Antarctic regions.

Researchers are also beginning to collaborate with native people, who often know a lot about the weather, plants, and animals that they see and rely upon. For example, Inuit in northern Canada noticed that weather patterns in their region had changed in way that scientists had not noticed. When researchers listened to the Inuit and collaborated with them, they documented new changes in local weather that they think are related to climate change.

The Arctic is a huge region, and scientists cannot conceivably measure every bit of it in person. So researchers also use other tools to study the Arctic from afar. They make observations using remote sensing, a variety of tools that allow them to measure factors that they cannot see directly, or which are too big to observe in person. Instead, they mount sensors on airplanes or satellites to record data. For example, satellite data provides estimates of the sea ice cover on the Arctic Ocean as well as weather patterns over the Arctic. And scientists from NASA recently flew a series of missions over the Arctic during the IceBridge project, to study details of Arctic sea ice thickness as well as changing glaciers in Greenland.

Researchers also combine their observations and data with computer models that try to replicate weather and sea ice conditions in the Arctic. Models can help scientists understand what effects higher temperatures will have, for instance, or whether declining sea ice cover on the Arctic Ocean will add to climate change.
