Rubber Duckie, You’re the One…Who Will Help Us Understand Global Warming

NASA researchers have released 90 rubber ducks into the Greenland’s Jakobshavn Glacier—the same glacier that may have sunk the Titanic a century ago—in an attempt to understand why glaciers move faster in the summer and why sea levels change. Because the Jakobshavn Glacier is known to discharge as much as seven percent of Greenland’s melting icesheets, NASA researchers are specifically interested in knowing how the meltwater moves through the glacier. While they can clearly see how the icebergs fall into the ocean, it’s impossible to see exactly how the water flows. In theory, as the sun warms the ice in the summer, the top layer of the glacier melts and flows through a hole in the glacier until it reaches the other side. As such, the researchers suspect the rubber ducks will end up in the surrounding water in Baffin Bay. The rubbery toys have the words “science experiment” and ...
