When organic material released from thawing permafrost is transported to the sea it gets broken down in the seawater contributing to a more rapid acidification of the Arctic Ocean, finds new research by scientists from Stockholm University and colleagues. Ocean acidification is an important consequence of humankind’s release of carbon dioxide (CO2) into the atmosphere from fossil fuel burning. It …
It’s spring at last! The course is plotted, the gear is packed, and the lines released. Fleets of pleasure boats can be spotted backing away from the docks that have housed them during the winter months. Besides overjoyed boaters, many recreational boats are loaded with anti-fouling paints that leak toxic tributyl tin (TBT) as well as copper and zinc into …
Professor Örjan Gustafsson received an ERC Advanced Grant to fund his team’s research into the effects of thawing Arctic permafrost on climate. There are large quantities of frozen organic matter and greenhouse gases trapped in the permafrost in shallow soils and in coastal sediments. A warmer climate could trigger the thawing, which in turn may cause release of those gases, …
