Sea ice<\/h1><\/div>[vc_column_text]<\/p>\n

Our northernmost sea areas are covered by ice. The sea ice plays an important role in the climate by reflecting sunlight back into space, and prevents the exchange of heat, moisture and gases between the sea and the atmosphere. In recent decades, the extent of the ice has decreased significantly. This makes the Arctic more accessible to human activity, but also increases the pressure on a vulnerable ecosystem.<\/p>\n

Movement, distribution, and thickness<\/strong>Sea ice is affected by what happens both in the air above and in the water below and is a good indicator of how the climate is changing. The ice cover has been declining drastically in recent decades, and the trend towards an increasingly blue Arctic is expected to continue. Studies of the sea ice are important in order to understand the rapid climate changes in the Arctic, and to manage risks associated with increasing human activity in the region.<\/div>
