Warm waterway found that could melt glacier

Scientists have discovered two pathways that are likely channeling warm ocean water under a massive Antarctic glacier, which could contribute to rising global sea levels, a study revealed on Tuesday.

The 120-kilometer-long Totten Glacier, more than 30 kilometers wide, is the largest in East Antarctica and melting more quickly than others in the area.

Research in Nature Geoscience showed a trough just under 5 kilometers wide has formed as a gateway deep under-neath the glacier, along with another tunnel.
