In July-August 2016 a team of researchers from Bristol, Sheffield, Leeds, Potsdam, Aberystwyth and NASA JPL camped on the Greenland ice sheet throughout the summer melt season to measure and monitor the changing colour of the ice and determine the causes of the darkening. In 2017 the project split into two teams – the first went in early (May-June) to observe the retreating snowpack and exposure of bare ice in spring. The second team will go in July-August to observe the peak of the melt season, when algae bloom most intensely and contaminants are concentrated onto the ice surface. This team’s measurements will enable the development new techniques for detecting ice surface contaminants and numerical models for the changing colour (and therefore melt rate) of the ice sheet.
