Current findings show that defrosting permafrost and carbon-rich overflow from Canadas Mackenzie River activate part of the Arctic Ocean to release more carbon dioxide (CO2) than it absorbs.Mackenzie Rivers Influence on Carbon EmissionsThe research study, published earlier this year in the journal Geophysical Research Letters, explores how scientists are utilizing modern computer system modeling to study rivers such as the Mackenzie, which flows into an area of the Arctic Ocean called the Beaufort Sea. Some of the carbon is eventually released, or outgassed, into the environment by natural processes.Like a conveyer belt of carbon, the Mackenzie River, seen here in 2007 from NASAs Terra satellite, drains pipes an area of practically 700,000 square miles (1.8 million square kilometers) on its journey north to the Arctic Ocean.” With our design, we are attempting to explore the real contribution of the seaside peripheries and rivers to the Arctic carbon cycle,” said lead author Clément Bertin, a researcher at Littoral Environnement et Sociétés in France.Such insights are vital since about half of the area of the Arctic Ocean is composed of coastal waters, where land meets sea in a complex accept. The ECCO-Darwin design is being used to study these blooms and the ties between ice and life in the Arctic.Scientists are tracking these seemingly small and large changes in the Arctic and beyond due to the fact that our ocean waters remain a critical buffer against a changing climate, sequestering as much as 48% of the carbon produced by burning fossil fuels.Reference: “Biogeochemical River Runoff Drives Intense Coastal Arctic Ocean CO2 Outgassing” by C.
