A huge dome of freshwater that is developing in the western Arctic Ocean is detected by UK scientists. Dr Giles and colleagues made their discovery using radar satellites belonging to the European Space Agency. This freshwater is coming in huge part from the rivers running off the Eurasian side of the Arctic sink.
A lot of research from buoys and other in-situ sampling had already indicated that water in this region of the Arctic had been freshening. One outcome of less sea-ice in the region is the likelihood that winds could now initiate greater mixing of the different layers in the Arctic Ocean. This would force the water together, raising sea surface stature, the group tells the journal Nature Geoscience.
