Supraglacial channel

    Newer Older

    Russell Glacier, Greenland

    Each ridge on the channel sides represents about a days worth of melt from the water flow. For scale, the channel is about 8-10 m deep here. Upstream lies a huge lake ~3km^2 in a depression on the ice-sheet surface. As the stream keeps eroding down, it would eventually cause the lake to drain rapidly within a matter of hours. The stream eventually flows to a huge moulin, where it then likely reaches the bed of the ice sheet, ~1000 m below.

    Lake-drainage events like these are common, and are currently being studied by scientists at Aberystwyth and Swansea Universities.

      Just writing to let you know about this person on Facebook that is stealing images and then watermarking them as though they were his own.

      Also he knows he is doing wrong so off and on he will hide his pages.

      You may end up having to point this out directly to Facebook.
