Glacial streams as a carbon sink

Scientists have only recently discovered that Arctic/glacial meltwater streams take in atmospheric carbon at a faster rate than tropical rainforests. Previously scientists have assumed that rivers were a source of carbon rather than a sink. The results were based on tests carried out on Ellesmere Island in Nunavut territory, Canada, the Rocky Mountains and in Greenland. Scientists studied the effects of glacial meltwater running into rivers and lakes downstream. In temperate rivers high levels of organic matter in rivers leads to ...
