A new study by the AWI shows that marine heatwaves have been taking a greater toll on the Arctic Ocean in recent decades and that there is an urgent need for further research In recent years, marine heatwaves have been taking an ever-greater toll on the world’s oceans and their ecosystems. Amplified by increasing […]
Hamilton, ON – Ground squirrel droppings, preserved for millennia in the Yukon’s deep permafrost, have yielded an enormous amount of environmental DNA from dozens of species of plants, insects, microbes and large mammals, offering detailed genetic information about an environment that no longer exists. It is among the oldest ancient DNA ever recovered and sequenced. In […]
An international team of scientists has, for the first time, quantified the total carbon stored in permafrost at the mouth of rivers flowing into the Arctic Ocean. According to a study recently published in the journal Nature Communications, about 1% of the world’s permafrost surface area lies in Arctic river deltas, which occupy an […]
New study explains what’s behind the toxic shift Scientists have identified the two biggest reasons that once-pristine rivers across the Arctic are growing cloudy with toxic orange iron particles that smother insects and suffocate fish. A new study published in Communications Earth & Environment builds on earlier research documenting widespread contamination in Alaska’s Brooks Range. As the climate warms, a […]
