Subglacial weathering alters nutrient cycles in Greenland
The nutrient cycles that underpin how carbon is stored and released from two of Greenland's glaciers is significantly affected by subglacial weathering, a new study has found, shedding further light on the geochemistry of meltwaters. The study, led by a team of isotope geochemists and glaciologists from the University of Bristol, measured the geochemical signature of the silica released from the Leverett Glacier in Southwest Greenland and the Kiattuut Sermiat in South Greenland.
