Glossary of Arctic Terms:
The fraction of light reflected by a surface back into space. Ice and other white surfaces have a high albedo (close to 1) while dark surfaces have a low albedo (close to 0). An albedo of 1 means that all incoming energy is reflected back out. An albedo of 0 means that the surface is absorbing all incoming energy. Albedos closer to 0 will cause more warming because they are absorbing more incoming energy. As snow melt increases, the Arctic albedo lowers, causing more heating leading to more snowmelt.
A plant or plantlike organism of any of several phyla, divisions, or classes. Algae is mainly aquatic, usually chlorophyll containing, but lacks a true stem, roots, leaves, and vascular tissue. It includes seaweeds and many single-celled forms.
An intergovernmental group of mostly foreign ministers representing the 8 nations bordering the Arctic, created by the Ottawa Declaration of 1996, to provide a means for promoting cooperation, coordination and interaction among the Arctic States, with the involvement of the Arctic Indigenous communities and other Arctic inhabitants to manage development and conservation of resources in the Arctic region.
An aquatic arthropod with hard shell, segmented body and jointed appendages such as crab, lobster, barnacles, shrimp, and copepods.
Single celled algae with silica shells.
Tourism directed towards natural environments to support their conservation efforts and observe wildlife sustainable without causing harm or destruction.
Species that are not found anywhere else
Externalities (negative and positive)
Side effects or consequences of economic activity that affect unrelated third parties. Externalities can harm the third party (negative externality) or benefit the third party (positive externality.)
A ship designed and equipped for breaking a channel through ice.
A mammal who lives in marine or aquatic environments. These include cetaceans (whales, dolphins and porpoises), pinnipeds (seals, sea lions and walruses), fissipeds (sea otters and polar bears), and sirenians (sea-cows including dugongs and manatees.)
Northern Sea Route
A sea route from the Barents Sea to the Bering Strait following the northern coast of Siberia.
A sea route between the Atlantic and Pacific following the northern coast of North America through the Canadian arctic archipelago.
Phytoplankton- Plankton plant life.
Plankton plant life
Small to microscopic organisms drifting or floating in the sea or freshwater. Plankton mainly consists of diatoms, protozoans (single-celled microscopic animal), small crustaceans and the eggs and larval states of larger animals. Plankton is the primary food source for many animals, and the base of many food chains.
Frozen seawater that moves with oceanic currents.
Plankton consisting of small animals and the immature life stages of larger animals.
