Australian scientists find huge amount of water held in subglacial lakes near the ocean.
Scientists have set off a series of small explosions beneath the biggest glacier in East Antarctica in order to peer beneath the ice and find out what lies beneath.
Scientists believe warm water beneath Totten may be accelerating the loss of ice, but without being able to see beneath the surface, it is difficult to understand exactly what is going on—or predict how the glacier will respond to warming global temperatures. The team set off a series of explosions two meters under the glacier surface. These explosions sent out soundwaves that researchers could then track as they echoed off layers of ice and bedrock. By doing this, they were able to build up an image of what exists below.
In December last year, NASA said more of East Antarctica’s glaciers are “waking up”—and this is a concern as scientists thought it was far more stable than the West Antarctic Ice Sheet, which experts believe is at risk of collapse. Maps published by the space agency indicate that the glaciers surrounding Totten are also losing ice—not at the same rate as glaciers in West Antarctica, but still enough to indicate that these frozen rivers are responding to changing conditions.
