(Newser) – A key experiment that may help unlock more secrets of global warming involves planting 90 rubber duckies into one of Greenland's fastest moving glaciers, Reuters reports. US scientists are hoping some of the ducks will be found as they emerge into Baffin Bay to help track rate and movement of melting ice in Arctic waters. A probe packed with electronics has also been inserted into the glacier.   

Each of the yellow plastic ducks are labeled with the words "science experiment" and "reward" in three languages, along with an email address. "It may take some time until somebody actually finds it and sends us an email," said one of the researchers. "These are places that are quite remote, so there aren't people walking around."
