We publish Canada’s greenhouse gas (GHG) and air pollutant emissions projections each year. The GHG emissions projections help us measure progress in reducing greenhouse gas emissions and combating climate change. GHG emissions projections are presented for a few scenarios. The air pollutant...

With the changing climate conditions, marine traffic along Canada’s coastal regions has increased over the past couple of decades and the need to improve our state of preparedness for oil-spill-related emergencies is critical. Baseline coastal information, such as shoreline form, substrate, and...

The Harlequin duck is a species at risk that occurs in the Torngat Mountains National Park. Fast-flowing rivers and streams constitute its breeding habitat but it is known to forgo breeding when abundance of aquatic insects is low. A helicopter survey is conducted every five years in late- July...

The Torngat National Park monitors the permafrost depth in the Ivitak wateshed. A temperature cable with 8 thermistors at depths from 0.5 to 7 m deep was installed in August 2010, and has been recording ground temperature at each depth at 8 hour intervals since that time. The site is a deep...

The Torngat National Park monitors the growth and extent of dwarf birch along elevational transects at 5 locations to understand how shrubs are changing the tundra vegetation in the park and sub-arctic regions. Each transect contains 3 or 4 plots, at lower slope, mid slope, and upper slope....

Soil and air temperature control the composition and productivity of tundra plant communities and different species of Arctic and alpine plants respond differently to changing soil and air temperatures, which can lead to changes in community composition The Torngat National Park monitors soil and...

Hydrology is a key factor affecting biodiversity and the ecological functioning of aquatic and riparian ecosystems through sediment transport, erosion, water chemistry, etc. Automated data loggers are being used to record year-round hourly measurments of absolute in-stream pressure, absolute...

Water temperature is a critical variable in stream ecology, and in particular has direct implications for fish populations. Automated data loggers are being used to record year-round hourly measurments of water temperature in various watersheds in Torngat Mountains national park. Note that...

The purpose of this page is to describe the organization of the greenhouse gas inventory report and to indicate where to find the online material. To learn more about Canada’s official greenhouse gas inventory, visit the Main page: https://www.canada.ca/ghg-inventory Contact us:...

The objectives of the present long‐term study, spanning a 45 year period, were to 1) investigate the temporal trends of total mercury (THg; muscle and liver) and selenium (Se; liver) in ringed seals (Pusa hispida) from different regions of the Canadian Arctic; and 2) examine possible...
