The thickness of the summer ice is challenging to measure from space during the summer. This is because ponds of meltwater can accumulate on the surface of the ice which lead to inaccuracies in satellite data. A paper published in Nature describes how scientists have now found an ingenious way of removing a problem of dazzle from this meltwater to yield the first ever year-round measurements of sea-ice thickness in the Arctic Ocean.
The photograph shows in-situ validation work in the Arctic as part of the research.
