Kluane National Park and Reserve has one of the largest concentrations of Dall’s sheep in the world. Dall's Sheep are highly valued by local First Nations and are also being monitored in neighbouring jurisdictions. Aerial survey counts of Dall's sheep have been monitored in four subpopulations since 1977. Rams, nursery (ewes and immature rams) and young of year (lambs) are recorded.
Kluane National Park and Reserve has the only naturally occurring population of kokanee salmon (Oncorhynchus nerka) in the Canadian national park system. In 2002, the population experienced a significant decline that resulted in extremely low numbers for well over a decade. The reason for the decline remains unknown and continued monitoring is necessary to shed light on possible causes. Spawning Kokanee salmon have been counted since 1976.
Amphibians worldwide are facing declines and possible extinction. Wood frogs (Lithobates sylvaticus) are the only amphibian in Kluane National Park and Reserve. They are considered an important component of wetlands and are highly valued by Southern Tutchone peoples. Threats to wood frogs in Kluane are primarily the loss of habitat due to climate change and infection by diseases such as chytrid fungus.
The Wind Imaging Interferometer (WINDII) was launched on NASA’s Upper Atmosphere Research Satellite on 12 September 1991 and operated until 2003. Its role in the mission was to measure vector winds in the Earth’s atmosphere from 80 to 110 km, but its measurements extended to nearly 300 km. The approach employed was to measure Doppler shifts from a suite of visible region airglow lines emitted over this altitude range. These included atomic oxygen O(1S) and O(1D) lines, as well as lines in the OH Meinel (8,3) and O2 Atmospheric (0,0) bands.
The Northern Lights are a fascinating natural phenomenon. These animated shows in the night sky have contributed to the mythology, folklore and art of many cultures and civilizations in the Northern Hemisphere. In 2007, as part of the THEMIS Mission (for "Time History of Events and Macroscale Interactions During Substorms"), NASA launched a constellation of five small satellites, all carrying identical suites of electric, magnetic, and particle detectors to study auroras. These satellites fly in carefully coordinated orbits to track disturbances in the magnetosphere.
MOPITT is a Canadian instrument aboard the Terra satellite. Since 1999, it has contributed to the study of environmental pollution by continuously scanning the troposphere to make long-term measurements of carbon monoxide concentrations. Initially planned for a five-year term, this experiment has been prolonged because the data collected is still of high quality and the satellite is in good health. Its data are used to assess the scope of certain pollution control initiatives and to help understand environmental effects of other human activities such as biomass burning.
Canada’s SCISAT is studying the complex chemical processes that affect the distribution of ozone in the upper atmosphere, especially over the Artic. From its orbit 650 kilometres above the Earth, its instruments use the light from sunrises and sunsets each day to identify more than 60 gases and particles. This successful mission represents a partnership involving universities, industry, and government.
