But while much of their focus has been on water's impacts on ice sheet change, their most recent research findings have overturned the order of their thinking. Meierbachtol, Harper and their team discovered that changes in the ice sheet have a real impact on the massive groundwater system underlying Greenland. This latest discovery occurred thanks to a marriage of drilling techniques. International cooperators made an angled hole 650 meters through bedrock underneath a Greenland glacier (冰川) to measure groundwater conditions under the ice. Meanwhile, researchers drilled 32 holes from atop the glacier, through nearly a kilometer of ice, to measure water conditions at the area between ice and bedrock, which forms an important boundary controlling groundwater flow below. After drilling, the team fixed sensors in the ice column and at the ice sheet bed to measure ice dynamics and water conditions as water flows under the ice. “By studying areas that were covered by ice 10,000 years ago, we have known that the huge mass and vast amounts of water from melting ice can impact the underlying groundwater,” Meierbachtol said. “It's generally accepted that the groundwater is sleeping over decades to centuries and its response to ice sheet change is long: thousands of years. But what we've shown here is that it is immediate.” This new understanding could have important subsequent effects on how Greenland's thinning impacts the Arctic. The thinning ice could reduce the rate of groundwater flow to the ocean, changing the water temperature and salinity (盐度) balance that is important for ocean circulation (循环) patterns. “In thinking about the complex feedbacks from Greenland's ongoing change, we have really ignored the groundwater component,” Harper said. 1.
